The audience, or intended u s e r s i n t h i s case, are g e n e r a l c o n t r a c t o r s and 3 c o n s t r u c t i o n managers, namely people who run c o n s t r u c t i o n j o b s on a day-to-day b a s i s and w i l l b e n e f i t from such a system. Other assumptions made which u n d e r l i e t h i s t h e s i s a r e : 1) The DSRS i s designed f o r g e n e r a l c o n t r a c t o r s and c o n s t r u c t i o n managers who are a l r e a d y employing some form o f d a i l y s i t e r e p o r t i n g . That i s , the i d e a behind t h i s t h e s i s i s not t o convince these people t h a t a d a i l y s i t e r e p o r t i s important because i t would be b e n e f i c i a l i n c l a i m s s i t u a t i o n s and would keep t h e i r s u p e r i n t e n d e n t s on t h e i r t o e s , e t c . . Instead, the i n t e n t i o n o f t h i s t h e s i s i s t o e x p l o r e the p o t e n t i a l uses o f the i n f o r m a t i o n i n a d a i l y s i t e r e p o r t by r e p r e s e n t i n g and a n a l y z i n g i t i n a computer environment; 2) The implementation o f the DSRS w i l l not r e q u i r e a d d i t i o n a l manpower a t the s i t e l e v e l . The superintendent w i l l be r e s p o n s i b l e f o r completing the r e p o r t as i n the p a s t . The s t o r e d i n f o r m a t i o n w i l l be analyzed a t the head o f f i c e by p r o j e c t management; and 3) The DSRS can be operated w i t h o r independently from the o t h e r i n f o r m a t i o n sub-systems (eg.

But t h i s a c t u a l l y means t h a t one can o n l y focus i n on a problem a f t e r i t has s u r f a c e d .

Then, the f o l l o w i n g steps were taken t o c a r r y out the r e s e a r c h : 1) Data c o l l e c t i o n forms were designed ( f o r t e s t i n g the 5 i n f o r m a t i o n t o be c o l l e c t e d and f o r g a t h e r i n g data f o r the e x p l o r a t i o n of p o t e n t i a l outputs and analyses) w i t h c a r e f u l c o n s i d e r a t i o n of how the i n f o r m a t i o n should be grouped t o f a c i l i t a t e easy i n f o r m a t i o n r e t r i e v a l i n the f u t u r e .

T h i s p r o x i m i t y was v e r y s i g n i f i c a n t because i t was agreed w i t h the company t h a t the s u p e r i n t e n d e n t would not have t o f i l l out the d a i l y r e p o r t s h i m s e l f which meant t h a t I had t o conduct data c o l l e c t i o n on s i t e everyday.

And, i t was thought t o be more convenient t o implement a new system a t the s t a r t of a p r o j e c t i n s t e a d of i n the middle of i t . Furthermore, s i n c e the r a t e of p r o d u c t i o n a t the f r o n t end of the p r o j e c t ("coming out of the ground") o f t e n v a r i e d g r e a t l y from job t o job, some of the t y p i c a l problem areas c o u l d be c a p t u r e d w i t h the proposed d a i l y s i t e r e p o r t s ; 3) Updating was f a c i l i t a t e d w i t h a l i s t o f a c t i v i t i e s t o serve as a c h e c k l i s t .

L i t e r a t u r e review was c a r r i e d out a g a i n f o r a d d i t i o n a l i d e a s ; 10) Both t e x t and g r a p h i c a l outputs were c o n s i d e r e d . S i n c e g r a p h i c a l outputs were not a v a i l a b l e on dBASE I I I PLUS, an a d d i t i o n a l software package was needed. Lotus 1-2-3 was employed f o r t h i s purpose. Only v e r y crude programs were w r i t t e n t o demonstrate these outputs (because the purpose of t h i s t h e s i s was system c o n c e p t u a l i z a t i o n and not software p r o d u c t i o n ) . N e v e r t h e l e s s , two c l a s s e s o f r e p o r t s were proposed: i ) D i r e c t Reports - s t r a i g h t data echoing; i i ) Analyzed Reports - r e q u i r e d data p r o c e s s i n g b e f o r e data were presented; and 11) A complete p i c t u r e o f the DSRS was o u t l i n e d t o show how the Data C o l l e c t i o n and R e p o r t i n g Systems would work t o g e t h e r . 7 1.4 THESIS STRUCTURE Presented i n t h i s t h e s i s i s a d e t a i l e d c o n c e p t u a l i z a t i o n of the micro-computer based DSRS which would operate as an i n t e g r a l p a r t of a c o n s t r u c t i o n p r o j e c t m o n i t o r i n g and c o n t r o l system.

Q u a l i t y o f Work - t h i s r e q u i r e s a s u b j e c t i v e r a t i n g (poor/fair/good) f o l l o w e d by comments i f p o s s i b l e ; . I n s p e c t i o n s - s i n c e s i t e i n s p e c t i o n s are always documented as a memo or r e p o r t by the i n s p e c t o r , t h i s s e c t i o n should simply i d e n t i f y the i n s p e c t o r (the name of the company, agency o r i n s t i t u t i o n only) and f o l l o w e d by a s h o r t d e s c r i p t i o n o f the i n s p e c t i o n (eg. l i n e 21 w a l l forms); and . T e s t s - s i m i l a r l y , t e s t s performed on s i t e are always documented as a r e p o r t . Thus, j u s t i d e n t i f y i n g the t e s t e r (the name o f the company, agency o r i n s t i t u t i o n only) and d e s c r i b i n g the t e s t s performed ( t e s t s r e s u l t s a re unnecessary, eg. co n c r e t e c y l i n d e r t e s t s on 35 MPa c o n c r e t e f o r s l a b on grade) would be adequate f o r t h i s s e c t i o n . Furthermore, t r a c k i n g o f d e f i c i e n c i e s may be c a r r i e d out i f a d d i t i o n a l comments such as " i n s u f f i c i e n t t i e ro d s " and " f a i l e d slump t e s t " are a l s o p r o v i d e d f o r the l a s t two items r e s p e c t i v e l y . I t s hould be noted t h a t the i n f o r m a t i o n items presented i n the above proposed d a i l y s i t e r e p o r t were not intended t o be complete. In f a c t , the subsequent f i e l d t e s t i n g was intended t o r e v e a l necessary changes t o t h i s d a i l y r e p o r t . 25 3.0 DEVELOPMENT OF THE COMPUTERIZED DATA COLLECTION SYSTEM 3.1 GENERAL CRITERIA The i n t r o d u c t i o n of micro-computers f o r p r o j e c t c o n t r o l (eg. S c h e d u l i n g System, DSRS, etc.) i s o f t e n not w e l l r e c e i v e d a t s i t e l e v e l . T h i s o p p o s i t i o n mainly comes from the e x p e r i e n c e d s i t e s uperintendent who has managed numerous jo b s over the years without such a i d s ; t h e r e f o r e , he or she i s v e r y s e t on how t o run the j o b . Moreover, t h i s person i s most l i k e l y t o be computer i l l i t e r a t e . Thus, some g e n e r a l c r i t e r i a f o r the development of the Data C o l l e c t i o n System must be e s t a b l i s h e d : 1) The system should be designed around the d a i l y s i t e r e p o r t i n g forms d e s c r i b e d i n s e c t i o n 2.2 because implementation of the computerized system w i l l be preceded by a d i s c u s s i o n (based on the t h e s e forms) on the i n f o r m a t i o n t o be c o l l e c t e d . T h i s way, even though the superintendent would have t o cope w i t h the o p e r a t i o n of the computer, a t l e a s t , the q u e s t i o n s and responses w i l l seem f a m i l i a r ; 2) The system must not overwhelm the s u p e r i n t e n d e n t w i t h e x c e s s i v e data c o l l e c t i o n time o r data volume.[37:435-436] The 15 minute time l i m i t s e t f o r r e p o r t i n g by p e n c i l and paper ( s e c t i o n 2.2) should a l s o apply here; 3) A n t i c i p a t e d responses should be p r e s e n t e d on the computer scre e n so t h a t data e n t r y can be e x p e d i t e d . Otherwise, the responses can be r e a d i l y r e v i s e d o r o v e r w r i t t e n t o r e f l e c t the a c t u a l o ccurrences o f the day.[13:4] T h i s technique i s commonly known as f u l l 26 s c r e e n e d i t i n g . Two oth e r i n p u t formats should a l s o be i n c o r p o r a t e d : s e l e c t i v e and f u l l s c r e e n t e x t i n p u t . S e l e c t i v e i n p u t r e q u i r e s the u s e r t o simply choose a response ( u s u a l l y by h i g h l i g h t i n g i t o r by e n t e r i n g the corres p o n d i n g item number) from a l i s t of p o s s i b l e responses. Whereas, f u l l s c r e e n t e x t i n p u t s o l i c i t s the response w i t h a blank f i e l d ; 4) The system should be menu d r i v e n as much as p o s s i b l e . At most, i t should o n l y r e q u i r e y o r n (yes o r no) responses t o get from s c r e e n t o screen; 5) The system should have e r r o r checking c a p a b i l i t i e s such t h a t o n l y i n f o r m a t i o n of the c o r r e c t format can be entered; 6) The system should be f l e x i b l e . I t should a l l o w easy c u s t o m i z a t i o n o f i n p u t d i s p l a y screens and be capable o f be i n g i n t e r f a c e d w i t h o t h e r p o p u l a r a p p l i c a t i o n software such as Lotus 1-2-3, MS Word, e t c . ; 7) The system should have p r o v i s i o n f o r b r i e f t e x t e n t r i e s a f t e r s e l e c t i v e i n p u t s ( r e c a l l d e f i n i t i o n from c r i t e r i o n 3) as t h i s c o u l d be used t o p i c k up a d d i t i o n a l i n f o r m a t i o n t h a t would have otherwise be l e f t u n s a i d ; 8) As mentioned i n s e c t i o n 2.2, keyword responses should be used t o s k i p over unnecessary o r non-a p p l i c a b l e q u e s t i o n s ; 9) The system should have a s e c u r i t y f e a t u r e t o prevent tampering o f s t o r e d data (eg. a password f o r system e n t r y ) ; and 10) The system should have the o p t i o n o f b e i n g i n s t a l l e d i n a l o c a l area network (LAN) environment whereby s i t e computers are d i r e c t l y l i n k e d t o those a t the head o f f i c e . T h i s would enable i n f o r m a t i o n r e t r i e v a l i n r e a l time. 3.2 DEVELOPMENT TOOLS Si n c e complete development of the DSRS i s not w i t h i n the realm o f t h i s r e p o r t , the development t o o l s (software and hardware) should be s e l e c t e d on the b a s i s o f t h e i r ease 27 o f o p e r a t i o n , c o m p a t i b i l i t y , a c c e s s i b i l i t y , and c a p a c i t y . The p r o t o t y p e DSRS d e s c r i b e d h e r e a f t e r was developed on dBASE I I I PLUS u s i n g a MS DOS-based micro-computer. Software Requirements S e l e c t i n g the data p r o c e s s i n g and management software package f o r the development of the p r o t o t y p e DSRS can be much more d i f f i c u l t than choosing the hardware simply because of the numerous c h o i c e s a v a i l a b l e i n todays market. The top o f the l i n e products i n c l u d e : Paradox, XDB, PowerBase, Open Access I I , DataEase, dBASE I I I PLUS, and R:BASE System V. However, any one of these packages would be s u i t a b l e f o r meeting the data p r o c e s s i n g and management demands of the p r o t o t y p e system (t h a t i s , choosing the b e s t database f o r the development of the a c t u a l DSRS i s not one o f the o b j e c t i v e s o f t h i s r e p o r t ) . dBASE I I I PLUS was chosen mainly f o r the f o l l o w i n g reasons: 1) The o r i g i n a l dBASE I I was one of the f i r s t proven commercial data p r o c e s s i n g and management software packages on the market. dBASE I I I PLUS i s even more powerful and r e f i n e d , and has become the i n d u s t r i a l s tandard. NOTE: a t the i n c e p t i o n o f t h i s development, dBASE IV (which w i l l meet or beat the c a p a b i l i t i e s o f i t s main competitors) had not been r e l e a s e d . However, Ashton-Tate c l a i m s t h a t a l l databases, forms, r e p o r t s , and a p p l i c a t i o n s developed i n dBASE I I I w i l l run without m o d i f i c a t i o n i n dBASE IV [3:113]; 2) I t can d i s p l a y , change, f i n d , r earrange, analyze, r e l a t e , and p r i n t any data t h a t has been s t o r e d i n a database; 28 3) I t f e a t u r e s a u s e r - f r i e n d l y menu d r i v e n A s s i s t a n t t h a t can be used t o develop s p e c i f i c a p p l i c a t i o n s , f o r example, c r e a t i n g s c r e e n formatted data e n t r y which g r e a t l y f a c i l i t a t e the data e n t r y p r o c e s s . As w e l l , i t can be used t o accomplish most of the day-to-day data management t a s k s ; 4) I t i n c l u d e s a programming language c a l l e d dBASE t h a t can be used t o c r e a t e customized a p p l i c a t i o n s f o r s p e c i f i c needs. Programming i n dBASE i s e a s i e r t o l e a r n than many oth e r programming languages because dBASE I I I PLUS has many b u i l t - i n f e a t u r e s (these f e a t u r e s w i l l not be d i s c u s s e d i n t h i s r e p o r t ; f o r more i n f o r m a t i o n , r e f e r t o the dBASE I I I PLUS us e r manuals); 5) dBASE I I I PLUS can be i n s t a l l e d i n a LAN environment. On a network, u s e r s w i t h a wide range of backgrounds and e x p e r t i s e can work wi t h dBASE I I I PLUS. For example, a t the s i t e l e v e l , u s e r s w i l l o n l y e n t e r data or operate ready-to-use programs and a p p l i c a t i o n s . Whereas, others w i l l program i n dBASE, c r e a t i n g database f i l e s and a p p l i c a t i o n programs a t head o f f i c e ; 6) dBASE I I I PLUS f i l e s can be converted such t h a t they can be imported and exported from and t o ot h e r software a p p l i c a t i o n s . T h i s i s extremely important because dBASE I I I PLUS does not have g r a p h i c s c a p a b i l i t i e s . For example, by e x p o r t i n g data t o LOTUS 1-2-3, graphs and b a r - c h a r t s can be r e a d i l y p l o t t e d ; and 7) I t f e a t u r e s a u t i l i t y c a l l e d PROTECT which can be used t o c r e a t e and ma i n t a i n s e c u r i t y on the system. T h i s important f e a t u r e i s not w i d e l y a v a i l a b l e i n today's a p p l i c a t i o n software. For example, E x p e d i t i o n , a t o t a l c o n s t r u c t i o n p r o j e c t document c o n t r o l package does not have a s e c u r i t y system, but i t i s c u r r e n t l y on the drawing board a c c o r d i n g t o one of i t s s a l e s r e p r e s e n t a t i v e s . [ 1 ] Hardware Requirements From a t e c h n i c a l s t a n d p o i n t , a micro-computer t h a t i s capable o f running dBASE I I I PLUS should be adequate f o r the DSRS. However, the time i t takes t o operate the system on s i t e cannot be overlooked s i n c e the system w i l l have t o be 29 t e s t e d i n the f i e l d e v e n t u a l l y . Given the a n t i c i p a t e d volume of i n f o r m a t i o n t h a t the system w i l l handle and the c r i t e r i o n o f m i n i m i z i n g o p e r a t i n g time, the computer should have a t l e a s t an I n t e l 80286 CPU and a hard d i s k d r i v e . 3.3 DATA ORGANIZATION Data o r g a n i z a t i o n addresses the q u e s t i o n s of how many databases are r e q u i r e d t o completely r e p r e s e n t the i n f o r m a t i o n on the d a i l y s i t e r e p o r t forms, what i n f o r m a t i o n should be c o n t a i n e d i n each database, and how these databases must be indexed i n order t o f a c i l i t a t e data r e t r i e v a l . The f o l l o w i n g c r i t e r i a were c o n s i d e r e d i n e s t a b l i s h i n g the number of databases r e q u i r e d and the i n f o r m a t i o n t h a t s h o u l d be s t o r e d i n each: 1) Group i n f o r m a t i o n such t h a t each database c a r r i e s one or a t most two r e l a t e d i d e a s . That i s , t h e r e i s no reason t o i n c l u d e weather i n f o r m a t i o n i n the same database as t h a t c o n t a i n i n g drawings a v a i l a b i l i t y i n f o r m a t i o n ; 2) C o l l e c t i n f o r m a t i o n t h a t c o u l d be r e p r e s e n t e d by the same database s t r u c t u r e (same s e t of f i e l d s , where a f i e l d i s an item of i n f o r m a t i o n w i t h i n a r e c o r d of a database) i n t o one database. For example, data r e l a t i n g t o the f i v e types of unusual developments a t the p r o j e c t l e v e l ( s t r i k e s / j o b a c t i o n s , p o t e n t i a l problems, d e l a y s , d i s p u t e s , and others) should be s t o r e d i n one database because t h e i r data c o u l d be r e c o r d e d i n the same format; and 3) Consider data m a n i p u l a t i o n requirements. The time i t t akes t o search and l o c a t e s p e c i f i c i n f o r m a t i o n w i t h i n a database should be minimized. S e a r c h i n g 30 and l o c a t i n g s p e c i f i c i n f o r m a t i o n g e n e r a l l y takes l o n g e r i n a l a r g e r database (more r e c o r d s and/or more f i e l d s ) than i n a s m a l l e r one. However, i t would be more cumbersome t o have t o assemble a number of databases ( i n s t e a d of having e v e r y t h i n g i n one) i n order t o r e t r i e v e some s p e c i f i c c a t e g o r y of i n f o r m a t i o n . Examples of these two d i f f e r e n t data s t o r a g e schemes are o u t l i n e d i n F i g u r e 3.1 along w i t h t h e i r r e s p e c t i v e advantages and disadvantages. Based on the above g u i d e l i n e s , twelve databases were needed t o most e f f e c t i v e l y r e p r e s e n t the i n f o r m a t i o n on the d a i l y s i t e r e p o r t forms. F i g u r e 3.2 shows the s e c t i o n ( s ) o f the d a i l y s i t e r e p o r t t h a t are r e p r e s e n t e d by each of the twelve databases. Each database w i l l be i l l u s t r a t e d by a customized s c r e e n d i s p l a y d u r i n g the data e n t r y p r o c e s s .

Notwithstanding the i n f o r m a t i o n on the d a i l y s i t e r e p o r t forms, the subsequent databases of the Data C o l l e c t i o n System c o n t a i n a d d i t i o n a l f i e l d e n t r i e s t o f u r t h e r enhance the comprehensiveness of the proposed d a i l y s i t e r e p o r t : 1) d s r h e a d . d b f (see F i g u r e 3.3) - DATA ENTERED BY: i n some i n s t a n c e s , the superintendent might have completed the d a i l y s i t e r e p o r t by p e n c i l and paper and computer data e n t r y was performed by a c l e r k .

As the name i m p l i e s , t h i s method r e q u i r e s the s u p e r i n t e n d e n t t o d i r e c t l y i n p u t the d a i l y s i t e i n f o r m a t i o n i n t o the computer without having t o complete the r e p o r t by p e n c i l and paper f i r s t (the r e p o r t would appear r i g h t on the s c r e e n as a s e r i e s o f windows). Then, the computer would generate a hard copy of the r e p o r t f o r the s u p e r i n t e n d e n t t o v e r i f y . Consequently, i t r e q u i r e s l e s s manpower and paper work. However, the f o l l o w i n g methods of data e n t r y were a l s o c o n s i d e r e d , but they were determined t o be i n a p p r o p r i a t e f o r t h i s a p p l i c a t i o n : 1) The B a s i c 2-Stage System - t h i s i s a d e s i r a b l e method f o r the superintendent who d i s l i k e s having a n y t h i n g t o do w i t h a computer.

Then the t a s k of computer data e n t r y may be c a r r i e d out by someone e l s e such as a c l e r k (second stage) . The major drawbacks of t h i s method are t h a t i t 42 i n v o l v e s more paper work, r e q u i r e s more manpower than D i r e c t Computer Input, and can r e s u l t i n e r r o r s d u r i n g computer data e n t r y . 2) The Turnaround Document [13:3] - t h i s i s a m o d i f i e d v e r s i o n of The B a s i c 2-Stage System.

But as t h e i r i n f o r m a t i o n needs grew, t h i s department found t h a t the forms were not d e t a i l e d enough, and some i n f o r m a t i o n items can be b e t t e r expressed w i t h supplemental comments.[23] Hence, they are now u s i n g a system c a l l e d the I n f o r m a t i o n R e t r i e v a l System (see Appendix B) t h a t i s s i m i l a r t o The Turnaround Document.

S c o t t C o n s t r u c t i o n agreed t o t h i s r e s e a r c h without h e s i t a t i o n . In f a c t , the company has been b e n e f i t i n g from Dr. R u s s e l l ' s computerized s c h e d u l i n g [30] over the p a s t few y e a r s ; thus, i t should p e r c e i v e t h i s r e s e a r c h as another p o t e n t i a l b e n e f i t t o the f i r m . I n v a r i a b l y , i t c o u l d r e c e i v e i n c r e a s e d j o b c o n t r o l without p r o v i d i n g a d d i t i o n a l r e s o u r c e s on s i t e . M o t i v a t i n g the s i t e s u p e r i ntendent t o cooperate w i t h the r e s e a r c h was a much more d i f f i c u l t and s e n s i t i v e t a s k . A p r o j e c t manager . of the company had s a i d t h a t t r a d i t i o n a l l y , the superintendent i s simply handed the s i t e and asked t o b u i l d the s t r u c t u r e . That i s , s u p e r i n t e n d e n t s are not t o l d how t o run t h e i r j o b s . T h e r e f o r e , i t became necessary t o c l e a r l y e x p l a i n t o Highbury's s u p e r i n t e n d e n t t h a t I was not working f o r the company, and t h a t he would not have t o worry about me being t h e r e t o r e p o r t on h i s performance t o s e n i o r management. J . C. S c o t t C o n s t r u c t i o n ' s management then confirmed my c l a i m by a s k i n g the s u p e r i n t e n d e n t t o cooperate on the b a s i s o f h e l p i n g a student complete h i s t h e s i s . 139 5.2 MANUAL DATA COLLECTION So f a r o n l y the f i r s t phase of manual data c o l l e c t i o n has been d i s c u s s e d . However, due t o J . C. S c o t t C o n s t r u c t i o n ' s i n c r e a s i n g i n t e r e s t i n improved d a i l y s i t e r e p o r t i n g , a second phase o f manual data c o l l e c t i o n was c o n c e i v e d d u r i n g the course of t h i s study. 5.2.1 THE FIRST PHASE - PERSONAL EXPERIENCE The f i r s t phase of manual data c o l l e c t i o n ran from June 1, 1988 t o August 16, 1988. P r i o r t o June 1, a s i t e meeting was s e t up w i t h the superintendent, a management r e p r e s e n t a t i v e , Dr. R u s s e l l , and myself. The purpose of t h i s meeting was t o f o r m a l l y i n t r o d u c e the r e s e a r c h t o the s u p e r i n t e n d e n t and t o seek h i s c o o p e r a t i o n . The superintendent, Mr. X, had been a s u b j e c t of computer s c h e d u l i n g r e s e a r c h on h i s p r e v i o u s job w i t h the company. T h e r e f o r e , he was used t o having t o p e r i o d i c a l l y " e n t e r t a i n " r e s e a r c h e r s on s i t e . And s i n c e we were prepared t o be v e r y f l e x i b l e and o n l y update whenever i t was convenient f o r him, he agreed t o cooperate. Mr. X f e l t t h a t r i g h t a f t e r l u n c h a t 12:30 pm would be the b e s t time t o conduct the s i t e r e p o r t i n g because of these reasons: . I n s t e a d o f having t o i n t e r r u p t h i s work t o do the 140 r e p o r t i n g , he c o u l d j u s t spend a few e x t r a minutes i n the s i t e o f f i c e b e f o r e going out i n t o the f i e l d a g a i n f o r the a f t e r n o o n . . By e a r l y a f t e r n o o n , he should have a f a i r l y good i d e a o f the p r o g r e s s o f the day; and thus, he should be a b l e t o answer most of the q u e s t i o n s on the forms. Any i n f o r m a t i o n t h a t was o v e r l o o k e d c o u l d be captured on the f o l l o w i n g day. Based on the above c o n d i t i o n s , the f i r s t phase of manual data c o l l e c t i o n was o f f i c i a l l y launched on June 1. Mr. X t u r n e d out t o be extremely c o o p e r a t i v e and h e l p f u l . On the f i r s t day, he showed me what i n f o r m a t i o n he u s u a l l y c o l l e c t s i n h i s own d a i l y j o b l o g ( a l l o f which i s a l r e a d y covered i n my forms wi t h the e x c e p t i o n o f equipment c o n t r o l ) and t o l d me how important i t i s t o keep such a d i a r y f o r l e g a l purposes. A p p a r e n t l y he had been i n v o l v e d i n a c o n s t r u c t i o n l e g a l d i s p u t e i n the p a s t . As I got t o know him b e t t e r , he became more and more t a l k a t i v e . In a d d i t i o n t o d a i l y s i t e r e p o r t i n g , he would t e l l me about some o f h i s p a s t jobs, e x p l a i n a c t i v i t y sequencing, e t c . . But most important of a l l , he was w i l l i n g t o admit h i s own mistakes (as shown i n F i g u r e 4.6b). T h i s honesty c o u l d be v i t a l t o the a c c u r a t e r e p r e s e n t a t i o n of a c t i v i t y problems. U n f o r t u n a t e l y , Mr. X took a l e a v e of absence on June 16. The p r o j e c t manager, Mr. Y, took over the j o b . P r i o r t o Mr. X l e a v i n g , I had met Mr. Y on s i t e and he was i n t r o d u c e d t o the d a i l y s i t e r e p o r t forms then. On h i s f i r s t day, Mr. Y recommended a couple of u s e f u l improvements 141 t o my system. He s a i d t h a t I should ask f o r the c o r r e s p o n d i n g a c t i v i t y i n f o r m a t i o n r i g h t a f t e r the work f o r c e i n f o r m a t i o n because he would l i k e t o d e a l w i t h each t r a d e o n l y once ( i f we were t o update a l l o f the work f o r c e i n f o r m a t i o n f i r s t and a l l o f the a c t i v i t y i n f o r m a t i o n second, then we would be going through the t r a d e s t w i c e ) . For the Work Force Information form, he a l s o suggested t h a t " S u f f i c i e n t (Manpower) t o Meet Schedule" should be changed t o " S u f f i c i e n t (Manpower) t o Meet Job C o n d i t i o n s " . The d a i l y r e p o r t i n g s e s s i o n s w i t h Mr. Y were u s u a l l y r a t h e r b r i e f . He would not t e l l me a nything u n l e s s I asked f o r i t e x p l i c i t l y . In f a c t , the a c t u a l r e p o r t i n g time (not i n c l u d i n g i n t e r r u p t i o n s such as telephone c a l l s , v i s i t o r s , e tc.) was never l o n g e r than f i f t e e n minutes. On days when he was v e r y busy, I would j u s t hang around the s i t e u n t i l he was f r e e or would ask f o r the i n f o r m a t i o n w h i l e f o l l o w i n g him around the s i t e . Sometimes, I would have t o spend more than two hours on s i t e i n o r d e r t o get the i n f o r m a t i o n t h a t I need. On o c c a s i o n , he even asked me t o f i l l i n the i n f o r m a t i o n myself; and, he would check i t the f o l l o w i n g day. But what I u s u a l l y wound up doing was t o l e t the foreman c o n f i r m the i n f o r m a t i o n a t the end of the day. And, s i n c e I was r e c o r d i n g job p r o g r e s s w i t h a v i d e o camera everyday ( s h o r t f i v e - m i n u t e t a k e s ) , I was a l s o a b l e t o use the tape f o r m i s s i n g data and data c o n f i r m a t i o n . 142 A c t u a l l y , Mr. Y t o l d me why he d i d not l i k e t o f i l l out d a i l y s i t e r e p o r t s ( i n c l u d i n g J . C. S c o t t C o n s t r u c t i o n ' s own v e r s i o n ) . He f e l t t h a t "paperwork, i n g e n e r a l , do not improve job e f f i c i e n c y " . As f o r the "Reasons f o r U n s a t i s f a c t o r y Rate of P r o d u c t i o n " l i s t on the A c t i v i t y I n f o r m a t i o n Form, he s a i d t h a t he and most o t h e r s i t e s u p e r i n t e n d e n t s ( e s p e c i a l l y younger guys who are p l a n n i n g t o keep t h e i r j o b f o r a while) would not t e l l me a n y t h i n g t h a t c o u l d be used a g a i n s t themselves. He concluded by s a y i n g t h a t e f f e c t i v e s i t e management i s r e a l l y knowing how t o d e a l w i t h people. N e v e r t h e l e s s , the v a r i a n c e a n a l y s e s i n s e c t i o n 4.3.5 show t h a t the d a i l y s i t e r e p o r t (of s e c t i o n 2.2) d i d c a p t u r e a f a i r number of problems d u r i n g the course o f t h i s r e s e a r c h . However, i n order t o determine the accuracy and comprehensiveness of these problem d e s c r i p t i o n s , one would have make estimated v e r s u s recorded comparisons on time l o s t and man-hours l o s t . The estimated v a l u e s are simply the t o t a l s found i n F i g u r e s 4.8 and 4.9. Whereas the r e c o r d e d v a l u e s would have t o be d e r i v e d from the S c h e d u l i n g System ( a c t u a l v s . planned d u r a t i o n s ) and the Cost C o n t r o l System ( a c t u a l v s . planned manpower e x p e n d i t u r e ) . In g e n e r a l , both s u p e r i n t e n d e n t s seemed t o be more comfortable w i t h p r o v i d i n g q u a l i t a t i v e responses over q u a n t i t a t i v e ones. A p o s s i b l e e x p l a n a t i o n f o r t h i s 143 behaviour i s t h a t they c o u l d be worry about s e n i o r management h o l d i n g them t o the estimated q u a n t i t i e s . 5.2.2 THE SECOND PHASE Implementation of the second phase of manual data c o l l e c t i o n began i n l a t e December, 1988. The main d i f f e r e n c e between the f i r s t phase and the second phase i s t h a t the l a t t e r arose from the company's i n t e r e s t i n t h i s t o o l . A f t e r r e v i e w i n g some of the sample outputs (from s e c t i o n 4.3), the company's p r o j e c t management r e a l i z e d the p o t e n t i a l o f such a system. They then urged Dr. R u s s e l l and myself t o d e s i g n a new form, p r e f e r a b l y o n l y one page i n l e n g t h , f o r a c t u a l s i t e implementation. The p r o j e c t managers would be r e s p o n s i b l e f o r s e l l i n g t h i s form t o t h e i r s u p e r i n t e n d e n t s who would be completing the d a i l y s i t e r e p o r t as a standard company form. T h e r e f o r e , s i m p l i c i t y and l e n g t h were the two most important c o n s i d e r a t i o n s i n the d e s i g n of t h i s form. We were t o l d t h a t the i n f o r m a t i o n requested had t o be v e r y s t r a i g h t forward and f r e e of c r o s s - r e f e r e n c i n g . A l s o , the l e n g t h of the form should be minimized because the s u p e r i n t e n d e n t s do not l i k e paperwork i n g e n e r a l , and the time r e q u i r e d t o f i l l out such a form may mean time l o s t f o r s u p e r v i s i o n . A f t e r two formal meetings and s e v e r a l d i s c u s s i o n s w i t h 144 the p r o j e c t managers, a new d a i l y s i t e r e p o r t form was designed f o r s i t e implementation (see F i g u r e 5.1). The i n f o r m a t i o n requested by t h i s form i n c l u d e s most, many o f the items d i s c u s s e d i n s e c t i o n 2.2. The major d i f f e r e n c e i s i t s PROBLEM SOURCE CODES. Instead o f c l a s s i f y i n g a c t i v i t y problems by type as i n F i g u r e 2.4, the p r o j e c t managers f e l t t h a t the f i r s t t h i n g they would l i k e t o know i s where the problems are coming from. T h i s l e d t o c l a s s i f i c a t i o n by problem sources (eg. weather, s i t e c o n d i t i o n s , owner, e t c . ) . As f o r the method of data i n p u t , the company p l a n s t o adopt The B a s i c 2-Stage System (as d i s c u s s e d i n s e c t i o n 3.4.1) whereby the p r o j e c t managers w i l l be doing the a c t u a l data i n p u t i n t o the computer. Si n c e t h i s system w i l l be used on a t l e a s t f o u r o f the company's c u r r e n t h i g h - r i s e p r o j e c t s , a s u b s t a n t i a l database c o u l d be b u i l t up f a i r l y q u i c k l y . Then, c o r r e l a t i o n analyses and v a r i a n c e a n a l y s i s i n t e r p r e t a t i o n should be c a r r i e d out. 5.3 COMPUTERIZED DATA COLLECTION Two o f J . C.

He added t h a t i f the foreman i s not up t o par, they would s e t t l e i t between the two of them. Thus, a more robust method of c a p t u r i n g s u b j e c t i v e l y r a t e d responses must be found. Namely, t h e r e i s a need t o c a t e g o r i z e such i n f o r m a t i o n items (as s i t e c o n d i t i o n s , crew s k i l l l e v e l , q u a l i t y and d e t a i l i n g of drawings, r a t e of 148 p r o d u c t i o n a t the a c t i v i t y l e v e l , and q u a l i t y of work) f o r more q u a n t i t a t i v e assessment. Dr. R u s s e l l proposed a s o l u t i o n t h a t i s c u r r e n t l y b e i ng t e s t e d i n the second phase of manual data c o l l e c t i o n .

Then, f o r example, the s u p e r i n t e n d e n t c o u l d not p o s s i b l y g i v e c o n s i s t e n t l y good s k i l l r a t i n g s f o r h i s men and a t the same time have slow r a t e s of p r o d u c t i o n (time l o s t ) f o r t h e i r a c t i v i t i e s i f no o t h e r problems were encountered. At any r a t e , c a l i b r a t i o n of s u b j e c t i v e responses should be f u r t h e r i n v e s t i g a t e d . 5.4.2 FEEDBACK FROM THE SECOND PHASE OF MANUAL DATA COLLECTION At t h i s stage of the second phase o f manual data c o l l e c t i o n , o n l y a couple of weeks of data have been c o l l e c t e d . N e v e r t h e l e s s , one p r o j e c t manager i n s i s t e d t h a t sample outputs f o r each p r o j e c t must be prepared f o r the r e s p e c t i v e s u p e r i n t e n d e n t s i n o r d e r t o keep them motivated on t h i s s u b j e c t of d a i l y s i t e r e p o r t i n g .

C. S c o t t C o n s t r u c t i o n ; 2) Two s e t s o f s h o r t and c o n c i s e d a i l y r e p o r t forms were designed f o r f i e l d t e s t i n g : a 3-form r e p o r t (see F i g u r e s 4.15bi, 2.3, and 4.14bii) and a 1-page r e p o r t (see F i g u r e 5.1); 3) Two phases o f manual data c o l l e c t i o n were implemented f o r t e s t i n g the d a i l y r e p o r t forms and g a t h e r i n g i n f o r m a t i o n f o r data a n a l y s e s . In the f i r s t phase, I s o l i c i t e d d a i l y s i t e i n f o r m a t i o n from the s u p e r i n t e n d e n t and entered the data i n t o t he 3-form r e p o r t . In the second phase, the supe r i n t e n d e n t s f i l l e d out the 1-page r e p o r t d i r e c t l y ; 4) Chapter 3.0 pr e s e n t s a framework f o r the Data C o l l e c t i o n System. S p e c i a l a t t e n t i o n was g i v e n t o a s c e r t a i n the most e f f i c i e n t data o r g a n i z a t i o n scheme (a combination o f the two data s t o r a g e schemes shown i n F i g u r e 3.1) and the most a p p r o p r i a t e method of data i n p u t ( D i r e c t Computer I n p u t ) . A pr o t o t y p e implementation was programmed on dBASE I I I PLUS t o e v a l u a t e some of the proposed f e a t u r e s o f the system and t o f a c i l i t a t e data a n a l y s e s . Once a custom i n t e r f a c e i s w r i t t e n , the DSRS c o u l d a u t o m a t i c a l l y update the computerized S c h e d u l i n g System i f the two share the same a c t i v i t y 151 and r e s p o n s i b i l i t y coding systems; and 5) Chapter 4.0 g i v e s an overview of the Data R e p o r t i n g System. Sample outputs were generated w i t h the data c o l l e c t e d from the f i r s t phase o f manual data c o l l e c t i o n . Both t e x t and g r a p h i c a l outputs are u t i l i z e d f o r s t r a i g h t data echoing and processed i n f o r m a t i o n . The outputs are p r e s e n t e d i n t h r e e d i f f e r e n t formats; D a i l y , Time S e r i e s , and Frequency of Occurrence. At t h i s time, a p r o t o t y p e Data R e p o r t i n g System has not been programmed. Most of the outputs were ob t a i n e d from dBASE I I I PLUS and Lotus 1-2-3 (where the data i n the l a t t e r were imported from the former v i a a b u i l t - i n dBASE I I I PLUS f u n c t i o n ) . However, i n i t s p r e s e n t form, the need f o r few improvements was r e v e a l e d : 1) Responses c o u l d be b e t t e r s t r u c t u r e d and s t a n d a r d i z e d . For example, the Data C o l l e c t i o n System should have b u i l t - i n s tandard menus of weather d e s c r i p t i o n s , t r a d e s , d e l i v e r y items, c o n s t r u c t i o n equipment, a c t i v i t i e s , i n s p e c t i o n s , and t e s t s t o f a c i l i t a t e data e n t r y . S i m i l a r l y , the Data R e p o r t i n g System would b e n e f i t from menus of p r o j e c t s , t r a d e s , d e l i v e r y items, c o n s t r u c t i o n equipment, a c t i v i t i e s , and problem t y p e s ; 2) S u b j e c t i v e problem r a t i n g s should be m o d i f i e d i n t o q u a n t i t a t i v e e n t r i e s as much as p o s s i b l e ; namely, s i t e c o n d i t i o n s (access, s t o r a g e , and ground c o n d i t i o n s ) , t r a d e s k i l l l e v e l and manpower l e v e l , a v a i l a b i l i t y and q u a l i t y of drawings, and q u a l i t y o f work performed. Otherwise, s u b j e c t i v e responses should be c a l i b r a t e d f o r more c o n s i s t e n t and a c c u r a t e r a t i n g s ; and 3) Performance i n d i c a t o r s must be e s t a b l i s h e d f o r subtrades i n order t o p o s t u l a t e c o r r e l a t i o n s between t h e i r performances and job problems. S i m p l i f i e d v e r s i o n s (so t h a t they can be implemented on a d a i l y b a s i s ) of some of F i g u r e 4.19's methods a v a i l a b l e f o r measuring q u a n t i t i e s might be s u i t a b l e . Even though the u l t i m a t e g o a l o f the DSRS i s t o do away w i t h w r i t t e n r e p o r t s and work d i r e c t l y w i t h t h e computer, 152 manual data c o l l e c t i o n should not be completely r u l e d out a t t h i s time because i t i s not y e t an i n d u s t r y norm t o have a s i t e computer. Thus, F i g u r e 6.1 p r e s e n t s a complete p i c t u r e of the DSRS under two p o s s i b l e methods of data c o l l e c t i o n . In a d d i t i o n , the data c o l l e c t e d i n t h i s study c o u l d be used t o generate an a s - b u i l t a c t i v i t y breakdown and sequencing f o r the p r o j e c t (see F i g u r e 6.2). T h i s i n f o r m a t i o n would be v a l u a b l e t o both c o n t r a c t o r s and r e s e a r c h e r s . F i r s t l y , s h o r t d u r a t i o n a c t i v i t i e s t h a t were not i n c l u d e d as p a r t of the schedule c o u l d be p i c k e d up by the d a i l y r e p o r t , thus e n a b l i n g the s c h e d u l e r t o b e t t e r scope the next s i m i l a r j o b . Secondly, t h i s i n f o r m a t i o n c o u l d be i n s e r t e d i n t o the database of an e x p e r t system f o r h i g h - r i s e c o n s t r u c t i o n s c h e d u l i n g . 6.2 RECOMMENDATIONS FOR FURTHER RESEARCH An immediate t a s k t h a t should f o l l o w t h i s r e s e a r c h i s t o a n a lyze the data c o l l e c t e d from the second phase of manual data c o l l e c t i o n . A s i d e from the v a r i o u s s t r a i g h t data echoing r e p o r t s and v a r i a n c e a n a l y s i s outputs, i t might be p o s s i b l e t o e s t a b l i s h some c o r r e l a t i o n s and c r i t i c a l c o n t r o l v a l u e s (eg. i n d i c e s t o a c t as e a r l y warning i n d i c a t o r s f o r s i g n i f y i n g s p e c i f i c problems) g i v e n the s u b s t a n t i a l s i z e of the new database.

Each Technician taking part in the survey is responsible for walking al l streets and lanes in a particular area of the City, and recording the conditions they observe on an inventory update sheet. In this way data is updated annually on the condition of every roadway, curb, sidewalk, boulevard, shoulder, and lane on City right-of-way. The data collected is used by the Streets Division for two main purposes: 1. To establish, estimate and priori t ize next year's street maintenance program. 2. To promptly repair unsafe conditions. An additional function of the data is to provide a historical record for legal claims against the City resulting from alleged street or lane hazards. 1. General "Streets Inventory Field Update" sheets record the results of last year's survey in the top row of each set of boxes (printed by computer). These sheets are designed so that al l items checked in the f ie ld for lanes and streets can be recorded on one sheet. Sheets are sorted into the east-west and north-south streets within each sub-distr ict , and are numbered in sequence in the upper right-hand corner. Books, each containing one sub-distr ict , are issued one at a time to each Technician. On completion of a book of these sheets i t is returned, signed in , and another book is issued in order of priori ty. (Specific distr icts must be completed before December so estimates can be made for next year's street maintenance program). Each "Streets Inventory Field Update" sheet may cover more than one "postal" hundred block segment of street. The extent of the information on any sheet is from intersection to intersection and considers address changes only by showing the hundred block range in the identification line at top of the sheet (example: 32-34 East Broadway). In addition to completing the "Streets Inventory Field Update" sheets, Technicians must record and hand out notices for shrubs, branches, hedges, and foliage which encroaches onto pedestrian pathways (see Figure 2-blank notice). Allowance should be made for a ta l l pedestrian (approximately 7 feet vertical clearance), and for branches that may sag when wet. Encroaching hedges should be trimmed at least 1' clear from the edge of sidewalks. 169 2. Use of the "Streets Inventory Field Update" Sheet 2.A. Explanation of General information. 1) For each sheet the Technician's name and the date of the inspection must be printed in the spaces provided in the upper right corner. 2) If a digit appears after the "Coords" (co-ordinates) code in the box labelled "Side", i t determines which roadway of a divided street the card refers to. A "1" in this location indicates the north or west roadway. A "2" indicates the south or east roadway. All undivided streets should have a "0" in this box. 3) The "Blk" (block), "Dir" (direction), "On Street" box indicates the location of the block by "postal" address. If i t is a long block containing more than a single hundred block segment, the sheet will show the multiple hundred block notation as previously mentioned. 4) The "At Street" box records the cross street at the north or west end of the block. This reduces the need for constantly referring to the house addresses as the technician rates each block. 5) With the increase in the number of streets and lanes with Asphaltic Concrete (A.C.) Pavements, special care should be taken to assure that the "Surface Type" code is correct. This code is most significant in Streets maintenance budgetting (see Table 1, for a l i s t of the codes). 6) The "Class" box indicates the functional classif icat ion of the road (e.g. ar ter ia l , residential , e tc . ) . If the code is in error, Technicians should note this in the "Comments" box. 7) An asterisk (*) in any box indicates that the previous rate, type or defect was missing or incorrect and that the Technician should take special note to correct the error. 8) Separate 'change' boxes are provided for changes just below the computer printed rates and defects. The new or revised information is to be entered using red pencil into the boxes provided, without the old or incorrect information being crossed out. If repairs have been completed a defect is deleted by the use of a zero "0" in the appropriate box. It  is very important that repaired defects are recorded this way. Any entire item to be deleted (e.g. lane) should have "delete" written through i t without changing any of the individual defects for that item. 170 9) Special note should be made of errors or omissions occurring for items which do not have a 'change' box; simply write the correct information just below the area where the figures should appear. The changes in street type, width, class, co-ordinate, name, blocks, or d ist r ic t will be coded (by others) in the office with an "Office Update" sheet. 10) Roadway surface defects are grouped as "Asphalt Surface", "Concrete Surface", or "Both" (defects are found in both types of surface). Unless a street contains a mix of asphalt and concrete surfaces, entries should only be made under 2 of the 3 groups. 11) There must be either a curb rate or a shoulder rate but not both. There is a possible exception where a divided roadway has a boulevard rate on a center island without curbs. 12) There must always be a type 1, 2, 3, 4, 5 or 6 for sidewalks or boulevards. If the type is a 4 (concrete) there must be a sidewalk rate. For types 1, 2, and 3 there must be a boulevard rate. A boulevard rate may occur with a type 4 and 6 sidewalk. 2.B. Explanation of Defects and Ratings 2.B.-1 Location When recording defect classes, defect extents, and ratings, be sure that you are using the correct update sheet for that location: Intersections Intersection information is to be recorded only on the update sheet for the block of street to the west. In cases where there is no street west of an intersection, the intersection is included with the block to the north, (see Figure 1). Lanes If the sheet is for a street which has an east-west co-ordinate, the lane to the south which is running the same direction as the street is to be rated on that sheet. A north-south lane must be rated on the sheet for the north-south street to the west. Two sets of boxes are provided for recording lane information on the update sheet. The f i r s t lane south or east of the road is lane No. 1, and should be recorded in the upper set of boxes. The second lane south or east is lane No. 2, and should be recorded in the lower set of boxes. See Figure 1 for an example of lane locations.
