Construction Cost Estimates

Construction cost estimates is an integral part of any construction project. Without this, construction costs can become a liability at a later stage of the project. A construction cost estimator is normally part of the budgetary planning process, making it one of the initial phases.

Project Feasibility Estimates

Project feasibility estimate as it applies to the area of reclamation can be defined as 'An estimate used for determining the economic feasibility of a project, the probable sequence and cost for construction of a project, and as a guide in the choice between alternative locations or plans'.

Project Cost Verification Report

A project cost verification report will generally include all the costs by the date of the report, where they are known, a forecast of the costs likely to be incurred during the rest of the project, in so far as these can be foreseen and estimated, and risk allowances for the possibility of unforeseeable costs.

Project Cost To Complete Reports

Cost To Complete Reports (CTC). A CTC is a detailed estimate that identifies the total cost of a project then deducts the cost of works that have been completed to date. This is then used to calculate the cost to complete the unfinished works.

Assessment Of Contract Variations

Any changes to the contract requiring a change to a particular section of work will lead to a Variation of Contract. A variation causes changes to the contract sum and can either be a positive or a negative amount and are generally assessed by a Quantity Surveyor and included in the monthly Progress Claim Assessments.
