Cost Analysis - 0401-533 Assignment 2: Cost Estimating, Uncertainty Analysis and Cost Planning Course: Question 1: 1) Perform quantity takeoff for the foundation structure provided in the following figure and

estimate the quantities of: 1. Excavation 2. Concrete including the concrete slab 3. Gravel 2) Design crew for excavation (labors, excavators, hauling trucks... etc.) to excavate the above quantity and to haul it to a dumping location 15 km far from the construction site. Estimate productivity of crew and cost of the excavation process 3) Evaluate uncertainty in the excavation productivity and estimate its impact on schedule and budget. Note: Include a list of all assumptions that you have made at the beginning of the analysis including any missing data in the drawing 45° 3' 0" 1' 0" typical 32' 0" Plan view Width 32' 0" रहे Length 85' 0" 4" concrete slab 4" gravel Typical section view 85' 0" 3' 0" 10' 0" 1'0" 3' 0" 3' 0" 45° Question 2: Given the bridge abutment shown below, estimate its construction cost. Data for this problem should be extracted from both: 1) UAE construction data and 2) Published data such as the RS Means Unit Price Estimating Methods (available in the University library). 1) Perform quantity takeoff of the formwork and concrete needed to build the abutment 2) Design minimum reinforcing steel mesh for the abutment (provide the reinforcing steel drawings) and do quantity takeoff of steel (Select appropriate design loads and specifications of the material) 3) Use resource numeration to design crews (labour and power tools) to build the formwork, to place concrete and to fix the reinforcing steel. 4) Specify productivity of the different crews 5) Estimate cost of the materials 6) Estimate cost per unit of work (i.e. cost per ton of fixing steel, cost per m³ of placing concrete... etc. 7) Study the market trends in term of adding overhead, contingency and profit and prepare a bid proposal to build the abutment package. 30' 50' 1' 30' 8′
