The developer may not specify the ready-mixed concrete supplier or purchase ready-mixed concrete directly. Yesterday, the website of the Beijing Municipal Construction and Construction Commission released the “Circular on Printing and Distributing Several Opinions on Strengthening the Management of Ready-mixed Concrete Production and Use”, which requires all units to strictly control the quality of construction projects.

"Notice" shows that the construction unit will be responsible for acceptance and inspection of ready-mixed concrete entering the construction site, and the supervision organization shall also supervise and sign the process of entering, sampling, maintaining, and submitting the concrete and sign and witness it. Beijing will, on the basis of the implementation of the procurement of ready-mixed concrete for construction projects, gradually implement online contracting or contract filing of the ready-mixed concrete sale contract, fly ash procurement contract, and the systemic sand purchase contract using tailings waste rock as raw material.

Since October last year, for the quality of housing construction, the Beijing Municipal Housing and Construction Commission has conducted a comprehensive inspection of the city's concrete mixing plant enterprises and further strengthened the quality supervision of the city's affordable housing projects. Subsequently, a number of companies that did not meet the regulations were punished and rectified. Before the end of 2011, Beijing will also complete the second batch of qualifications review and green production compliance assessment for the mixing site, and strive to achieve more than 80 standard mixing stations.
