Problem: Discuss the different estimating techniques that are used for construction projects by answering the following questions in your post:
Required:
Question 1: What are the three most common types of estimating techniques, and in what situation is it most appropriate to use each one?
Question 2: What else is important to consider when deciding which technique to use?
What kind of soil labs are good for the construction which is underlying the wet clay is dense sand. For example, compaction, and so on.
An invert (surface of the bottom arc) level of 4 m from the ground surface is proposed for a water pipe 2 m in diameter. Draw the soil profile and locate the water pipe. Explain any issue (justify with calculations) with locating the water pipe at..
A concrete hollow box culvert is shown in Figure P14.12. A basement for a building is required near the culvert. One proposal is to construct a sheet pile wall to surround the excavation, as shown in Figure P14.12, and pump out the water in the ex..
A gate (shaped like .25 of a cylinder with radius R=3m) is used to control the flow of water through a canal.The height of the water in the tank is 30m. How much force must be applied to keep the gate from opening? The gate is 30m wide.
A sample of coarse aggregate weights 1072 grams when oven-dried, 1091 grams when saturated surface-dried, and 667.6 grams when submerged. Calculate the bulk specific gravity, apparent specific gravity, and percent absorption.
Water, at volume flow rate Q=20 L/s, is delivered by horizontal fire hose and nozzle assembly. The hose (L = 100m, D = 75 mm, and e/D = .004) is made up of five 20 m sections joined by couplings
