9) Thermal Correction: The correct parts out in order to increase the heating temperature of steel, plastic, reduce stiffness, use of force or deformation of the cooling contraction of the correction process.

10) investment estimates, project billing, project tendering environment, environmental engineering tender?

A: The investment estimate is the construction unit in the project investment decision-making process,virtuemart template, according to the provisions of existing data and the estimation methods on a construction project to estimate the amount of the investment documents.

project settlement refers to the period of construction and installation works, construction units and construction units around the construction and installation, price calculation, payment matters Bafu and economic exchanges took place behavior.

Environmental Engineering tenders: means a contract in accordance with the statutory tender process for the proposed project is funded by their own or entrust a consulting company (or Management Company) the preparation of tender documents, invitation to tender by public tender or competitive way, merit-based determine the general term for a series of work the contractor.

Environmental Engineering units Tender Tender Tender is the whole process, including engineering design and construction tender bid.
