A Project budget reflects the financial plan of the operations, divided into responsibility centres, with specific goals clearly outlined along with the costs expected to be incurred. The primary purpose of having a budget is to assign financial targets and resources to each responsibility centre, to coordinate their activities, to form the basis for controlling performance, and to make the participant’s cost consciousness instead of purposeless routine working.

The budget uses the language of accounting to state objectives and measure performance. The project budget integrates monetary objectives, responsibilities and allocated resources. The base of the budget is the project plan and its schedule of work. The project functional organization is structured into responsibility centres. Each responsibility centre is assigned labour, equipment and budgeted costs for the assigned goals. And, finally, the project financial plan is presented in the form of the master budget which summarizes all the budget information like profit and loss statements, balance sheets, capital expenditure budget, cash flow forecasts and performance indicators.

In a construction project, the client and the contractor have separate budgets. Although, the project schedule of work and work done value (or earned value) form the common baseline for developing these budgets, their purpose differs.

The client’s construction budget is primarily a capital budget designed to formulate time-phased funds requirement and the sources from which these funds are to be provisioned. The client capital budget includes the expenditure on preliminaries, procurement of land, client supply resources, consultants fee, contractors payments and the cost of working capital.

On the other hand, a contractor’s budget is resources-cost and sales-income oriented budget. It includes quarterly statements of income and expenditure and forecast of financial statements of projected balance sheet, cash flow, profit and loss and performance measuring baselines. The break up of a typical contractors budget is shown in fig.

The project budget making process goes through the following stages:

a)     Structuring responsibility centres.

b)    Budgeting sales and assigning a sales target to each responsibility centre.

c)     Budgeting production expenses necessary for the fulfillment of assigned tasks of each responsibility centre.

d)    Provisioning for inflation and escalation.

e)     Forecasting profit and loss, cash flow statement and balance sheet.

f)      Preparing a project master budget.
