1. The concept of determining the basis of construction project investment
The basis for determining construction project investment mainly includes engineering quota, bill of quantities, factor market price information, engineering technical documents, environmental conditions, project construction organization and technical scheme, etc.
2. Construction project quota
The concept of (1) quota
Construction engineering quota, that is, the quota consumption standard of construction engineering,
(2) the generation of quota
The production of quota is closely related to the production and development of management science.
(3) Classification of quotas
1) According to the reflected material consumption content, it can be divided into labor consumption quota, material consumption quota and mechanical consumption quota.
2) According to the classification of construction procedures, it can be divided into basic quota or budget quota, budget quota (index) and estimation index (as the basis for the investment estimation of project proposal and feasibility study report).
3) According to the characteristics of construction engineering, it can be divided into construction engineering quota, installation engineering quota, railway engineering quota, highway engineering quota and water conservancy engineering quota.
4) According to the scope of application, quotas can be divided into national quotas, industry quotas, regional quotas and enterprise quotas.
5) According to the classification of construction costs and expenses, the quota can be divided into direct quota, indirect quota and other expenses quota.
3. Quantity list
(1) concept of bill of quantities
Refers to the construction project issued by the tenderer, in accordance with the unified rules of engineering quantity calculation, project division and measurement unit calculation of engineering quantity, listing all the bidding projects. If the bidder wins the bid and signs the contract, the bill of quantities can become an integral part of the contract.
(2) the role of bill of quantities
1) provides an open, fair and just competitive environment for bidders.
2) It is the basis of pricing, inquiry and bid evaluation.
3) Provide a basis for paying the project progress payment in the construction process.
4) Provide important basis for project settlement, completion settlement and project claim.
5) For a project subject to tender with a pre-tender estimate, the tenderee shall prepare the pre-tender estimate with the bill of quantities for reference in bid evaluation.
(3) the content of the bill of quantities
The bill of quantities includes two parts:
1) Description of bill of quantities
2) Bill of Quantities
Reasonable list item setting and accurate project quantity are the premise and foundation of the list.
(4) the principle of compiling the bill of quantities
1) Comply with relevant national laws, regulations and policies.
2) List items must be set in accordance with the unified national project division, measurement unit and engineering quantity measurement rules, and the engineering quantity calculation should follow the provisions of "three unifications".
3) Comply with the relevant requirements of the tender documents.
4) The compilation basis of the list shall be complete.
5) The compilation should be accurate and reasonable, that is, the calculation of engineering quantity should be accurate, and the setting of list items should be reasonable, without leakage or weight.
4. Other basis for determining investment in construction projects.
(1) engineering technical documents
(2) Factor market price information
(3) Environmental conditions of the construction project
(4) Others
