Temporary Heating in Construction Contracts

Abstract

It appears that in construction projects extending through winter with freezing temperatures, the cost of temporary heating is not always equitably resolved between the parties in a contract. Although existing guidelines have been initiated since 1964 by the construction industry, the bid allowances in calendar days and cost perdiem of heating, as suggested, have not been implemented. The three case studies described with varying structures and heating systems, show how heating costs are affected by changes beyond the General Contractor's control. These costs can be substantial; however, they can be minimized if owner, designer, contractor and mechanical subcontractor can cooperate.
