National Examinations — May 2014 — 07-Str-B2 Management of Construction. Three hours, closed book; candidates may use one of the two approved calculators (Casio or Sharp). The paper prints six questions of equal value (20 marks each) and states that any five questions constitute a complete paper, only the first five appearing in the answer book being marked. Candidates are urged to submit a clear statement of any interpretive assumptions with their answers. All six questions are worked below, because this set is intended as a study resource rather than as a single exam sitting.

Reference texts: RSMeans, Building Construction Cost Data — the "How to Use the Cost Data" front matter, which defines daily output, labour-hours, bare costs and the Total Incl. O&P column used in Question 1; Halpin, D.W. & Senior, B.A., Construction Management (4th ed., Wiley) — unit-price estimating, crew balancing, labour relations and construction safety; Hegazy, T., Computer-Based Construction Project Management (Prentice Hall) — precedence networks with SS/FS/FF relationships and lags, which is exactly the notation of Question 2; Hendrickson, C. & Au, T., Project Management for Construction (2nd ed., Carnegie Mellon) — scheduling and cost control; Sullivan, W.G., Wicks, E.M. & Koelling, C.P., Engineering Economy (17th ed., Pearson) — present-worth analysis and the maximum-justified-investment problem of Question 4; Canadian Construction Documents Committee, CCDC 2 — Stipulated Price Contract (2020), General Conditions 6.5 (delays) and 6.6 (claims for a change in Contract Price); Goldsmith, I. & Heintzman, T.G., Goldsmith on Canadian Building Contracts (5th ed., Thomson Reuters) — delay and notice law in Canada; AACE International, Recommended Practice 29R-03: Forensic Schedule Analysis — the but-for and windows methods named in Question 5; British Columbia Labour Relations Code, RSBC 1996 c. 244 — certification, bargaining units and the construction-industry provisions behind Question 3; WorkSafeBC, Occupational Health and Safety Regulation (Parts 4, 8, 11, 18 and 20) and the BC Workers Compensation Act — the prime-contractor duty and the traffic-control, fall-protection and hazardous-substance rules behind Question 6.

Check — two readings taken from the printed page. The RS Means extract in Question 1 prints two cells as question marks; both are recovered below from the crew table, and the recovered labour-hour figure is checked against the printed $27 labour column before it is used. Two arrows leave the right-hand edge of activity D and turn vertically to reach E and C; they are read here as ordinary finish-to-start links, which is the only reading consistent with the drawing and with the fact that every unlabelled arrow on the sheet carries no lag.
