工程量清單（Bill Of Quantity BOQ）是在19世紀(jì)30年代產(chǎn)生的，西方國(guó)家把計(jì)算工程量、提供工程量清單專業(yè)化為業(yè)主估價(jià)師的職責(zé)，所有的投標(biāo)都要以為主提供的工程量清單為基礎(chǔ)，從而使得最后的投標(biāo)結(jié)果具有可比性。
工程量清單報(bào)價(jià)是建設(shè)工程招投標(biāo)工作中，由招標(biāo)人按國(guó)家統(tǒng)一的工程量計(jì)算規(guī)則提供工程數(shù)量，由投標(biāo)人自主報(bào)價(jià)，并按照經(jīng)評(píng)審低價(jià)中標(biāo)的工程造價(jià)計(jì)價(jià)模式。
工程量清單報(bào)價(jià)的指導(dǎo)原則是：政府宏觀調(diào)控、企業(yè)自主報(bào)價(jià)、市場(chǎng)形成價(jià)格、社會(huì)全面監(jiān)督。
工程量清單計(jì)價(jià)實(shí)行的是一種由招標(biāo)單位出具建設(shè)項(xiàng)目的工程量清單，投標(biāo)企業(yè)對(duì)照招標(biāo)企業(yè)提供的工程量清單，根據(jù)企業(yè)的管理組織水平的技術(shù)能力，充分考慮市場(chǎng)和風(fēng)險(xiǎn)因素，根據(jù)投標(biāo)競(jìng)爭(zhēng)策略進(jìn)行自主報(bào)價(jià)。投標(biāo)企業(yè)在報(bào)價(jià)過(guò)程中，必須通過(guò)對(duì)單位工程成本、利潤(rùn)進(jìn)行分析、統(tǒng)籌考慮、精心選擇施工方案，并根據(jù)企業(yè)定額合理確定人工、材料、機(jī)械等要在經(jīng)濟(jì)上的投入與配置，優(yōu)化組合，合理控制現(xiàn)場(chǎng)費(fèi)用的施工技術(shù)措施費(fèi)用，確定投標(biāo)價(jià)。這就要求投標(biāo)企業(yè)改變過(guò)去依賴國(guó)家發(fā)布的定額狀況，提高企業(yè)的施工組織管理水平，改善施工技術(shù)條件，注重市場(chǎng)信息的搜集和自身信息集累，根據(jù)自身

Of quantities (Bill Of Quantity BOQ) is produced in the 19th century, 30s, and Western countries to calculate quantities, bill of quantities provided professional duties of appraisers for the owners, all bidders must be provided to the main bill of quantities basis, making the final tender results comparable.
BOQ is the work of construction project bidding by the tenderer in accordance with national unity calculation rule for the engineering project the number of self-quotation from the bidders and low bid in accordance with accredited project cost pricing model.
BOQ's guiding principle is: the government's macro regulation and control, enterprise autonomy offer, the market price formation, social and overall supervision.
Quantities implemented is a unit issued by the construction project bidding of quantities, tender bidding companies provided corporate control of quantities, according to the level of enterprise technology management organizations ability to give full consideration to market and risk factors, according to tender autonomy offer competitive strategy. Tender companies offer process, must work on the unit cost, profit analysis, and consider carefully select the construction plan, and reasonable under the corporate scale to determine manpower, materials, machinery and other inputs to the economic and configure, optimize, reasonable control of the cost of construction-site costs of technical measures to determine the tender price. This calls for tender issued by the State enterprises to change the past, rely on a fixed position, raise the level of organization and management of construction enterprises, construction technology to improve the conditions, pay attention to market information, information collection and its accumulation, according to its own
