(a). (b). When pricing a BOQ, what elements go into the unit rate analysis? Compute the total estimate for constructing a building foundation of a structure shown in Figures (Q4a) to (4c) up to and including the 100 mm concrete slab. Clearly show the analysis of how rates for main items have been built up. The cost of some major materials are given in Table Q4. Use appropriate assumptions where necessary. 4 Table Q4: Cost of some major materials Material Welded Steel Fabric (A98), 60x2.4m Unit Price (MWK) Damp proof membrane (50m x 1.2m) Roll 900,000.00 Shutterply (2.4mx1.2m) Roll 80,000.00 Diesel fuel No 60,000.00 Petrol fuel litres 2,734.00 19mm Aggregates litres 2,520.00 14mm Aggregates m3 25,000.00 9.5mm Aggregates m3 22,000.00 Ordinary Portland Cement m3 21,000.00 Softwood Timber (150x50mm) bag 25,000.00 Softwood Timber (100x50mm) No 15,00.00 No Softwood Timber (50x50mm) 10,000.00 No 6,000.00 River sand m3 10,000.00 Skilled labour hr 1500.00 Unskilled labour Transport day 1,500.00 m3/km 6,500.00
