建筑业总产值  是以货币形式表现的建筑业企业在一定时期内生产的建筑业产品和提供的服务的总和。建筑业总产值包括：

⑴建筑工程产值：指列入建筑工程预算内的各种工程价值。

⑵安装工程产值：指设备安装工程价值，不包括被安装设备本身的价值。

⑶其他产值：建筑业总产值中除建筑工程、安装工程以外的产值。包括房屋构筑物修理产值、非标准设备制造产值、总包企业向分包企业收取的管理费以及不能明确划分的施工活动所完成的产值。

a.房屋构筑物修理产值：指房屋和构筑物修理所完成的产值，但不包括被修理房屋、构筑物本身价值和生产设备的修理产值。

b.非标准设备制造产值：指加工制造没有定型的非标准生产设备的加工费和原材料价值(如化工厂、炼油厂用的各种罐、槽，矿井生产统一使用的各种漏斗、三角槽、阀门等)以及附属加工厂为本企业承建工程制作的非标准设备的价值。

建筑业增加值  指建筑业企业在报告期内以货币形式表现的建筑业生产经营活动的最终成果。

从2004年第一次全国经济普查开始，建筑业现价增加值按生产法和分配法(收入法)两种方法计算，以收入法的计算结果为准，即从收入的角度出发，根据生产要素在生产过程中应得的收入份额计算。具体计算方法：经济普查年度建筑业增加值按照《经济普查年度GDP核算方案》计算，非经济普查年度建筑业增加值按照《非经济普查年度GDP核算方案》计算。

房屋建筑施工面积  指在报告期内施过工的全部房屋建筑面积，包括本期新开工的房屋面积、上期施工跨入本期继续施工的房屋面积、上期停缓建在本期恢复施工的房屋面积、本期竣工的房屋面积及本期施工后又停缓建的房屋面积。

(2) Output value of installation projects:  the value of the installation of equipment, (excluding the value of the equipment to be installed);

(3) Other output values: the output value of construction industry apart from that of construction projects and installation projects. It includes: output value of repair of buildings and structures; output value of non-standard equipment manufacturing; overhead expenses received by contracted enterprises from the sub-contracted enterprises and the completed output value of construction activities for which there is no clear definition.

a. Output value of repair of buildings and structures:  the value created through the repairs of buildings or structures. It does not include the value of buildings or structures being repaired and the value of the repair of production equipment;

b. Output value of manufactured non-standard equipment: the value of non-standard production equipment, including raw materials and manufacturing cost, made for the construction project (i.e., chemical plant; kettles or tanks used by refineries; various fillers, triangle tanks, valves used by mines). It also includes the output value of equipment manufactured by subsidiary workshops.

Value-added of Construction refers to the final result of the activities of production and operation of enterprises of the construction industry in monetary terms during the reference period.
