The paper investigates the current practices of cost estimation involved in tendering and invoicing of construction projects under execution for construction works in Saudi Arabia. It shows that most of the practices use standard methods established by several government agencies while rely on bidding based on unit price tender documentation. This paper proposes the adoption of KSU-ESTIMATE, a computerized estimation program developed in King Saud University, which can be used in associate with the available AutoCAD program. The KSU-ESTIMATE is able to be linked with related databases pertinent to cost indices of materials, labours, labourers, and personnel. The program helps architects, contractors, employers and other decision makers to calculate the cost estimate of a project. The program supply designers with guidance which allows manipulation of building material schedules and window and door schedules in relation to cost. The manipulated project attributes helps design contractor and project manager to obtain a quick and accurate cost of the project and prepare invoices for individual items in construction projects.
