Pre-construction Services
Pre-construction services are used in planning a construction project before the actual construction begins. These services are often referred to as preconstruction or precon. It is a modern practice, considered to be part of construction project management, which is the overall planning, coordination, and control of a project from inception to completion aimed at meeting a client’s requirements in order to produce a functionally and financially viable project. Overview In the long established design-bid-build method of construction project delivery, a project would be entirely designed before being built. This resulted in a package of plans and specifications which formed the construction documents. The owner would then request bids (or tenders) for the project and award the project to a successful bidder, who would then build the project. Often the early feasibility, studies, and design development is supported by construction cost estimators, who prepare cost estimates for us ...

Construction Management
Construction management (CM) is a professional service that uses specialized, project management techniques and software to oversee the planning, design, construction and closeout of a project. The purpose of Construction management is to control the quality of a project's scope, time / delivery and cost—sometimes referred to as a project management triangle or "triple constraints." CM is compatible with all project delivery systems, including design-bid-build, design-build, CM At-Risk and Public Private Partnerships. Professional construction managers may be hired for large to jumbo-scale, high budget undertakings (commercial real estate, transportation infrastructure, industrial facilities, and military infrastructure), called capital projects. The role of a contractor Contractors are assigned to a construction project during the design for a constructibility review or once the design has been completed by a licensed architect or a licensed civil engineer. This is done by go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cost Estimate
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate. A cost estimator is the professional who prepares cost estimates. There are different types of cost estimators, whose title may be preceded by a modifier, such as building estimator, or electrical estimator, or chief estimator. Other professionals such as quantity surveyors and cost engineers may also prepare cost estimates or contribute to cost estimates. In the US, according to the Bureau of Labor Statistics, there were 185,400 cost estimators in 2010. There are around 75,000 professional quantity surveyors working in the UK. Overview The U.S. Government Accountability Office (GAO) defines a cost estimate as "the summation of individual cost elem ...

Construction Bidding
Construction bidding is the process of submitting a proposal ( tender) to undertake, or manage the undertaking of a construction project. The process starts with a cost estimate from blueprints and material take offs. The tender is treated as an offer to do the work for a certain amount of money (firm price), or a certain amount of profit ( cost reimbursement or cost plus). The tender, which is submitted by the competing firms, is generally based on a bill of quantities, a bill of approximate quantities or other specifications which enable the tenders to attain higher levels of accuracy, the statement of work. For instance, a bill of quantities is a list of all the materials (and other work such as amount of excavation) of a project which have sufficient detail to obtain a realistic cost, or rate per described item of work/material. The tenders should not only show the unit cost per material/work, but should also if possible, break it down to labour, plant and material costs. In th ...
