contractor may provide work with its own forces, but it is common for a general contractor to limit its role primarily to managing the construction process and daily activity on a construction site (see also construction management). During the construction phase the architect also acts as the owner's agent to review the progress of the work as it relates to pay requests from the Contractor, and to issue site instructions, change orders (or field orders), or other documentation necessary to facilitate the construction process and certify that the project is built to the approved construction drawings. Potential problems of design–bid–build Failure of the design team to be current with construction costs, and any potential cost increases during the design phase could cause project delays if the construction documents must be redone to reduce costs. Redesign expense can be disputed should the architect's contract not specifically address the issue of revisions required to reduce costs. Development of a "cheaper is better" mentality amongst the general contractors bidding the project so there is the tendency to seek out the lowest cost sub-contractors in a given market. In strong markets, general contractors will be able to be selective about which projects to bid, but in lean times, the desire for work usually forces the low bidder of each trade to be selected. This usually results in increased risk (for the general contractor) and can also compromise the quality of construction. In the extreme, it can lead to serious disputes involving quality of the final product, or bankruptcy of a sub-contractor who was on the brink of insolvency desperate for work. As the general contractor is brought to the team post design, there is little opportunity for input on effective alternates being presented. Pressures may be exerted on the design and construction teams due to competing interests (e.g., economy versus acceptable quality), which may lead to disputes between the architect and the general contractor, and associated delays in construction. Benefits of design–bid–build The design team looks out for the interests of the owner. The design team prepares documents on which all general contractors place bids. With this in mind, the "cheaper is better" argument is rendered invalid since the bids are based on complete documents. Incomplete, incorrect or missed items are usually discovered and addressed during the bid process in the form of addenda. Ensures fairness to potential bidders and improves decision making by
