Your submittal should include the quantity take-offs and cost estimates presented for both alternatives as shown above in a
table format (one table each).
Construction Cost Estimate Assignment A land developer plans to build a new building on a site that has marginal soil conditions. The geotechnical engineer has identified two alternative foundation systems for this proposed building: Alternative 1: Support the building on pile foundations that extend through the marginal soils into the deeper stronger soils. Alternative 2: Excavate the upper 10 feet of soil and replace it as a compacted fill. The proposed building may then be supported on spread footing foundations founded on the compacted fill. Both alternatives will use a slab-on-grade floor. In addition, both aiternatives will produce a foundation system with equal quality and reliability, and the construction time will be about the same. Neither will require any future maintenance. Thus, the only consideration in selecting the final design is the respective cost of the foundation construction. The structural engineer developed preliminary design drawings for both alternatives, and these drawings show the following: - The proposed building will be rectangular with plan dimensions of 150ft by 200ft. It will have 36 interior columns and all of the perimeter walls will be bearing walls. - For Alternative 1, each column will require four piles, each of which must be 25ft long. In addition, each column will require a 553ft reinforced concrete pile cap. The exterior bearing walls will require 25ft long piles at 10ft on center, and a 22ft reinforced grade beam along the base of the wall. - For Alternative 2, each column will require a 10103ft reinforced concrete spread footing, and the exterior bearing walls will require a 32ft reinforced concrete continuous spread footing. The civil engineer developed a preliminary site plan and grading plan. For Alternative 2, the excavation and recompaction will extend 10ft beyond the building footprint, as recommended by the geotechnical engineer. The civil engineer also determined that Alternative 2 will require 1500 cubic yards of import fill to make up for the shrinkage that will occur during the excavation and recompaction process. Develop hand-drawn sketches of each alternative showing the relevant items needed to develop the cost estimate. Include relevant dimensions. The unit cost information is as follows: Compute the construction quantity take offs and develop construction cost estimates for both alternatives. Present this information using the following format (just an example here): Based on the results of this analysis, recommend a course of action.
