Construction processes Design team Shasta Dam under construction In the modern industrialized world, construction usually involves the translation of paper or computer based designs into reality. A formal design team may be assembled to plan the physical proceedings, and to integrate those proceedings with the other parts. The design usually consists of drawings and specifications, usually prepared by a design team including the client architects, interior designers, surveyors, civil engineers, cost engineers (or quantity surveyors), mechanical engineers, electrical engineers, structural engineers, and fire protection engineers. The design team is most commonly employed by (i.e. in contract with) the property owner. Under this system, once the design is completed by the design team, a number of construction companies or construction management companies may then be asked to make a bid for the work, either based directly on the design, or on the basis of drawings and a bill of quantities provided by a quantity surveyor. Following evaluation of bids, the owner will typically award a contract to the lowest responsible bidder. Construction Manager as Constructor Under this delivery method, a construction manager is hired prior to the completion of the design phase to act as a project coordinator and general contractor. Unlike the DBB method, a construction manager is hired during the design phase, which allows the construction manager to work directly with the architect and circumvent any potential design issues before completion of the construction documents. After documents are completed, the construction manager accepts bids for the various divisions of work from subcontractors or general contractors. Lorich Construction Management LLC Value Engineering otential problems of Design-Build: Cost estimating for a design-build project is sometimes difficult because design documents are often preliminary and may change over the course of the project. As a result, design-build contracts are often written to allow for unexpected situations without penalizing either the Design-Builder or the owner. Several organizations (such as the Design/Build Institute of America) provide standardized form contracts for design-builders to use, but it is not unusual for the design-builder to provide its own contractual documents. This uncertainty requires the owner to rely a great deal on the integrity, accumen, and competence of the design-builder. As the certainty of estimates decreases, the opinion of the construction professionals of the Design-Build firm must be trustworthy, accurate, and reasonably verifiable in order to minimize risk.

This approach has become more common in recent years and includes an entire completed package, including fixtures, fittings and equipment where necessary, to produce a completed fully functional building. In some cases, the Design and Build (D & B) package can also include finding the site, arranging funding and applying for all necessary statutory consents. The owner produces a list of requirements for a project, giving an overall view of the project’s goals. Several D&B contractors present different ideas about how to accomplish these goals. The owner selects the ideas he likes best and hires the appropriate contractor. Often, it is not just one contractor, but a consortium of several contractors working together. Once a contractor (or a consortium/consortia) has been hired, they begin building the first phase of the project. As they build phase 1, they design phase 2. This is in contrast to a design-bid-build contract, where the project is completely designed by the owner, then bid on, then completed. Kent Hansen, director of engineering for the National Asphalt Pavement Association (NAPA), pointed out that state departments of transportation (DOTs) usually use design build contracts as a way of getting projects done when states don’t have the resources. In DOTs, design build contracts are usually used for very large projects. Large projects can involve highly complex financial plans. As portions of a project are completed, they may be sold, supplanting one lender or owner for another, while the logistical requirements of having the right trades and materials available for each stage of the building construction project carries forward. In many English-speaking countries, but not the United States, projects typically use quantity surveyors. Lorich Construction Management LLC Value Engineering :The design-bid-build method is the most common construction delivery method. This process begins with an owner selecting an architect to prepare construction documents. These are prepared using drafting standards such as the Institute of Civil Engineers ICE Conditions of Contract, or the NEC Engineering and Construction Contract. In most cases, the architect will release these construction documents publicly, or to a select group of general contractors, who will then place a bid on the project which reflects what they believe cost of construction will total. This bid is inclusive of a multitude of subcontractor bids for each specific trade. The general contractor’s fee is generally built into the bid cost. Most government contracts are bid competitively using this method. Lorich Construction Management LLC Management Procurement Procurement describes the merging of activities undertaken by the client to obtain a building. There are many different methods of construction procurement; however the three most common types of procurement are: 1. Traditional (Design-bid-build) 2. Design and Build 3. Management Contracting Traditional Main article: Design-bid-build This the most common method of construction procurement and is well established and recognized. In this arrangement, the architect or engineer acts as the project coordinator. His or her role is to design the works, prepare the specifications and produce construction drawings, administer the contract, tender the works, and manage the works from inception to completion. There are direct contractual links between the architect’s client and the main contractor. Any subcontractor will have a direct contractual relationship with the main contractor.
