1. A normal-weight concrete has an average compressive strength of 4500 psi. What is the estimated modulus of elasticity? A short plain concrete column with dimensions of 12 in. x 12 in. x 36 in. is to be constructed. If the compressive strength of the concrete is 5000 psi, what is the maximum load that can be applied to this column using a factor of safety of 1.2? Consider a standard flexural strength specimen of length L, width a, and depth a. Assume third point loading where the load at failure from the test machine is P, which is distributed evenly (½ to each) over the two loading points. Derive the equation for calculating the modulus of rupture of the beam in terms of P, L, and a.

Cost control

Cost control or management in property or project management is the process by which managers maintain costs under human resource management, assets, and capital expenditure to ensure that the project ends on a budget basis. Cost management depends on reasonable estimates and ongoing monitoring during the project. As a result, good cost control is essential for any construction business that wants to succeed.
