The financing cost depends on the incoming and outgoing cash flow throughout the project, and can differ greatly from project to project. This study proposes a model that calculates the expected financing cost based on the cash flow forecast. This approach is more realistic than assuming an approximate percentage of the total cost. The proposed mod...

Although a few studies have considered financing cost in the construction project, no research has been conducted to select the optimal financing alternatives out of those offered by financial institutions. This study presents a model that minimizes financing cost by considering different financing alternatives and a work schedule with normal activ...

Time-cost tradeoff analysis allows a contractor to build a project using an optimal schedule that leads to minimum cost. The financing cost can be minimized if the financing decision considers different financing alternatives such as short-term and long-term loans and lines of credit. Financing optimization should be integrated into time-cost trade...

This paper discusses the findings of a study conducted under the direction and supervision of the ASCE Committee on Management Practices in Construction (MPIC) to investigate the expectations of the parties involved in the construction process including designers, general contractors, subcontractors, owners, construction managers (CMs), and educato...

Purpose: Planning for increased contractor profits should start at the time the contract is signed because low profits and lack of profitability are the primary causes of contractor failure. This research proposes an integrated profit maximization model (IPMM) that aims for maximum expected profit by using time-cost tradeoff analysis, adjusted star...

Contractors need financing throughout a project, mainly because (1) the owner withholds retainage to make sure that the project is performed properly by the contractor, and (2) the periodic payments made by the owner are usually delayed. Since financing has a cost, the integration of financing and scheduling is of vital importance in managing const...

Contractors need financing throughout a project, mainly due to retainage, which is the money that the owner withholds to make sure that the project is performed properly by the contractor. Even if an owner does not withhold retainage, financing is still necessary because the periodic payments made by the owner are usually delayed. All pertinent st...

The disturbed state concept (DSC), originally developed by Desai during the past two decades, was found very beneficial in modelling granular materials as well as others. A deforming elasto-plastic engineering solid, according to this concept, can be considered as a composition of these two states where the portion of the second state, i.e. the ful...

Behavior of rockfills was investigated experimentally and theoretically. A series of standard triaxial compression tests were carried out on a quarried rockfill material at different stress levels. It was found that both the stress level and the shear stress ratio, like most of granular materials, controls the behavior of rockfill materials. At low...
