Whether the design drawings conform to the national and relevant technical policies, economic policies and relevant regulations. Whether the design meets the construction technology and equipment conditions, whether there are technical difficulties when special technical measures are needed, and whether the safety construction can be ensured. Whether there are special materials, including new materials, and whether their varieties, specifications and quantities can meet the requirements. Whether there are contradictions among buildings, structures, equipment and pipelines, and whether the equipment layer, tube well, shaft size and floor thickness meet the installation requirements. The foreman's disclosure should be scientific, and the so-called science means correct basis, correct understanding and correct disclosure. Specifications, procedures, drawings, atlas and standards are all effective at present, which is the premise. The key is to understand them correctly, turn them into their own things and use them flexibly. The most important thing is to explain to the operation team that they are construction technical documents that integrate various technical documents, so that the operation team can carry out the construction correctly according to the disclosure. The foreman's disclosure should be targeted, and the design and construction instructions should be overcome as technical disclosure. This is the same, and each building number is the same, but it can't guide the construction in the end. According to the construction characteristics of this building, the disclosure is carried out to really guide the construction. Concrete. For example, the drainage system: install from the casing, reserve holes, whether the distance between the pipeline and the wall refers to the clean wall or the structural wall, the form and distance of the clip, the slope and verticality of the pipeline, the connection mode, the required quality target, etc. It should be specific. Comprehensive. Draw details if the drawings are unclear, and the team cannot be allowed to play freely; If the drawings are unclear, they should be supplemented to prevent the operators from misunderstanding or losing items. Practicality. The words "construction in accordance with design drawings and construction and acceptance specifications" should not be used to explain the disclosure. The control points on the design drawing, such as the connection mode, the form of fixing clips, brackets and brackets, the slope, the distance from the wall, the connection mode, the requirements for corrosion protection and pressure test, should be clearly written.
