When a project is over budget, the problems caused by overrun are seldom felt by only one member of the construction team.
Every member is affected in some way.
For this reason, a project's budget needs to by analyzed at several project phases including predesign, design, and construction phases. Materials or systems of higher quality than necessary used to obtain the required finished product. Construction documents with too much ambiguity, paving the way for change orders. Underbidding by the contractor of project costs. Additional time needed to complete the construction schedule.
