Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.

Consider a soil that is being placed as a fill and compacted using a sheepsfoot roller (a pieceof construction equipment). Will the action of the roller change the void ratio of the soil?Explain.
One of your junior engineers has submitted a construction quality (CQC) plan foryour review before it is sent to the client. The CQC plan includes a compactionspecification for the compacted clay liner. The specification requires that the clay becompacted to a dry unit weight 92% of maximum dry unit weight (standard Proctor)and wet of standard Proctor optimum water content. Compaction and hydraulicconductivity-water content curves for the soil are shown in the figure below. The clayliner is required to have hydraulic conductivity1 x 10-7cm/sec. Find the acceptablezone based on hydraulic conductivity. Does this specification ensure that the requiredhydraulic conductivity will be obtained?

An earth dam requires 1 million cu.m. of soil compacted to a void ratio of 0.80. In the vicinity of the proposed dam, three borrow pits were identified as having suitable materials. The cost of purchasing the soil and the cost of excavation are the same for each borrow pit. The only cost difference is transportation cost. The table below provides the void ratio and the transportation cost for each borrow pit. PLEASE COMPLETE SOLUTION 1. Compute the volume of soil if taken from borrow pit C.2. Compute the transportation cost of the soil if taken from borrow pit B.3. Which borrow pit would be the most economical?
= Construction of an embankment needs 400,000 yd3 of fill. The fill should be compacted to at least 88% of the standard Proctor maximum dry density obtained in the lab, which is gammad_d,max : 128 pcf, but the contractor plans to exceed that by 2% to ensure passing quality control. The fill may be obtained from two companies (A and B) with the following profiles. Company A Distance from borrow pit to embankment: 25 miles Cost of haul ($/yd3-mile): 0.50 Cost of fill material ($/yd3): 1.50 Borrow soil moisture content: 16% Specific gravity of solids: 2.70 Degree of saturation: 70% Company B Distance from borrow pit to embankment: 30 miles Cost of haul ($/yd3-mile): 0.40 Cost of fill material ($/yd3): 1.40 Borrow soil moisture content: 18% Specific gravity of solids: 2.65 Degree of saturation: 58% The total cost of haulage by company A (million $) The total cost of haulage by company B (million $) The relative compaction, CR, should account for the contractor's plan to exceed the minimum…

The Undisturbed soil at a given borrow pit is found to have the following parameters. The water content is 15%, the void ratio is 0.60 and the specific gravity of the solids is 2.70.The soil from this borrow pit is to be used to construct a rolled fill having a finished volume of 50,000 yd3. The soil is excavated by means of a shovel and dumped on trucks. When loaded to capacity these trucks are found to contain, on average, a net weight of wet soil equal to 13,000 lbs.In the construction process, the trucks dump their load on the fill, the material is spread and broken up, after which a sprinkler adds water until the water content is equal to 18%. The soil and water are thoroughly mixed by means of dicers (or other similar equipment) and then compacted until the dry unit weight γd=110 lbs/ft3 Helpful Conversions (3ft=1yd), (γw=62.4 lbs/ft3), (7.48gal/1ft3) a) Assuming that each load is a capacity load, how many truck loads are required to construct the fill?b) What is the volume in…
