Supervision's review and approval of project documents During the project construction process, a large number of documents are generated from beginning to end. Some of these documents need to be entered into the infrastructure files after the project is completed, and some involve the quality and progress of the project. , cost and other control traceability and basis; therefore, supervisors must carefully review and approve project documents. Especially for those who are new to the supervision industry, they need to learn and master this basic skill. This article explains some common and commonly used points and methods for review and approval of engineering documents.
1 General Principles
(1) All documents must be reviewed and stamped (except quality acceptance records), signed (signature), dated, and stamped according to different requirements, including unit seal, It is divided into project seal, contract seal and quality inspection seal; the validity date of the certificate shall also be reviewed. Documents (including copies) must be clearly written; foreign language materials should be provided in Chinese. Documents issued by each unit should have clear sequential numbers.
(2) The filling format of project documents and the use of forms must comply with the regulations and requirements of local urban construction files and construction project quality and safety supervision.
(3) Approval should be careful and rigorous, and have basis and facts. The main basis is current laws, regulations, contracts, designs, specifications, meeting minutes, etc.
(4) The timeliness of approval must be paid attention to, especially for documents that need to be rejected, the approval must be timely to avoid project quality problems and claims.
(5) The review and approval should also state whether it is agreed or not and any content that needs to be supplemented by the applicant.
2 Review and approval of the start-up report
(1) Review the start-up conditions: various construction application procedures have been completed or filed, the contract has been signed, the design drawings have been approved, and the construction organization design The (plan) has been approved, the site layout and "three connections and one leveling" have been completed, and construction resources have been allocated and implemented.
(2) The start-up report must be stamped with the unit seal and cannot be replaced by the project seal.
(3) The start date must comply with the start date requirements stipulated in the contract.
(4) The approval should state the date on which construction is agreed to start or indicate the conditions that need to be met to start construction.
3 Review and approval of construction organization design (plan)
(1) Review the integrity of the content. Including preparation basis, project overview, project organization composition, construction methods, quality management system and quality assurance system, progress plan (network or bar chart), configuration of construction resources (labor force, machinery, equipment), safe and civilized construction matters, site plan (temporary plan) layout) drawings, etc.
(2) Review the correctness of the basis for preparation. For example, the laws, regulations, and procedures listed in the basis must be currently valid and applicable to all project scopes and majors involved in this project.
(3) Review pertinence and operability. Some of the construction organization designs (plans) largely copy or reproduce the content of other similar projects, which are often inconsistent with or very different from this project, and have little significance for specific construction guidance; some are not small in length, but full of general principles. The empty provisions appear to be strict and comprehensive, but in reality they are frivolous and have poor operability. In particular, hoisting and adjustment plans must be reviewed for pertinence and operability. For example, in the hoisting plan, all equipment and anchor points used for hoisting must be calculated to determine their stress and location (generally, they shall not be changed during implementation. If any Changes require recalculation).
(4) City progress plan. The planned construction period must meet the contract construction period requirements; the progress plan of a unit project should be refined into divisions, the progress plan of a divisional project should be refined into sub-items, and the progress plan of a high-rise or multi-building construction project should be refined into floor batches or building numbers. ; And review the rationality and feasibility of the overlap between each major and each process, and review whether the resource allocation can meet and guarantee the progress.
(5) The cover must be stamped with the unit seal and the signature of the approver (unit leader or chief engineer), and cannot be replaced by the project seal and the signature of the project technical leader.
4 Joint review of drawings
(1) Review the validity of the drawings. The drawings must be stamped with the "Special Seal for Issuance of Design Documents" and the "Special Seal for Review of Construction Drawings and Design Documents" of the unit with professional qualifications, and the registration seal of the qualified designer: design, proofreading, review, approval, professional responsibility in the signature column , design chief and other signatures are complete. The drawings need to be approved by relevant government departments (planning, fire protection, civil air defense, environmental protection, etc.).
(2) Review design depth.
The design description and construction description, including the annotation clauses under the drawings, are the focus of the drawing review. For example, the design of process parameters, working condition requirements, and the selection of main equipment and materials should be explained; the design drawings should be able to meet the construction needs, including There are drawings such as system diagrams and necessary cross-sections.
(3) Review the design for correctness. It should comply with the relevant design specifications, especially whether it complies with the mandatory provisions in the specifications and the requirements stipulated in the fire protection regulations.
(4) If all majors are jointly reviewed, the correlation and joint points between majors need to be reviewed, such as the connection between air ducts, air outlets and buildings, and the connections between water, electricity, and air pipelines in densely populated areas. Whether the wiring setting method is reasonable and feasible.
5 Qualification review and approval of subcontracting units
(1) Qualification review. Business license, construction (production) license, enterprise qualification certificate, tax and financial status certificate, legal person (legal person authorization) qualification certificate, academic qualifications, professional titles, professional qualifications, qualification certificates of key management personnel, recent performance of similar projects, etc. Conduct inspections when necessary.
The examination must be detailed. For example, when examining a business license, it is necessary to look at the nature of the enterprise, date of establishment, registered capital, and business scope to roughly judge the scale, popularity, and professionalism of the enterprise.
(2) Review the nature of subcontracting: it must not be subcontracting, dismemberment subcontracting, layered subcontracting or other illegal activities, otherwise it will be rejected.
6 Special industries and special operations review
(1) Special industries, such as curtain walls, elevators, boilers, pressure vessels, fire protection, etc., must review their design, production, installation, etc. Practicing qualifications.
(2) Special operations personnel, such as scaffolders, electricians, welding, lifting, elevators and other construction personnel must review their operating license qualifications.
7 Review and approval of materials, components, and equipment
(1) Review the correctness of selection. Model, specifications, materials, performance and inspection indicators, and crystal brands must meet the requirements of design and specifications as well as the owner's requirements for brand grade.
(2) Review product qualification certificates and information. The product must have recent certification of a complete set of product inspections (type inspection and factory inspection). Equipment products must also have installation, use, maintenance instructions and other information. Software product information must also provide program structure instructions and interface specifications. Products with national mandatory requirements must undergo 3C certification; products with special requirements such as fire protection, explosion-proof, and waterproof must undergo performance index inspection; measurement products must have a qualification certificate approved by the quantity management department, and imported products must undergo commodity inspection certificate.
(3) The copy of the manufacturer’s inspection certificate issued by the agent must be stamped with the agent’s red seal and indicate where the original is.
(4) Materials that need to be sampled for inspection on site and products that need to be inspected before installation (such as tightness inspection of valves and nozzles) must be inspected and recorded.
(5) Approval should state whether the product is qualified after visual inspection (inspection), whether the selected product meets the design and specification requirements, whether it is allowed to enter the site and agreed to be used in the proposed location, or indicate all the remaining information that needs to be provided. If the documents are missing, we will make a decision after verification.
8 Quality acceptance record review and approval
(1) The division of project quality acceptance shall be implemented in accordance with the "Uniform Standards for Quality Acceptance of Construction Projects" (GB 50300-2001).
(2) Project quality acceptance standards must be filled out clearly and completely in accordance with professional specifications and design requirements. For example, pipeline project pressure test records must include pipe section number, material, working pressure, temperature, medium for strength test, Pressure, time and conclusion, medium, pressure, time and conclusion of tightness test.
(3) The approval must state whether the inspected main control items and general items meet the specification requirements and whether the construction quality is qualified; if the approval of the pipeline engineering pressure test record is required, it must also state whether the test pressure is Observe the time, pressure drop, voltage stabilization time and other processes.
9 Review and approval of project progress payment
(1) Review the project completion amount. On-site measurement of completed projects that have passed inspection, and review of their quality acceptance records.
(2) Mark the completed work amount accordingly on the drawings and indicate the month of completion.
(3) The approval shall indicate the amount to be paid according to the proportion stipulated in the contract and the amount to be deducted according to the contract.
(4) Establish a progress payment approval ledger. The monthly declared amount and approved amount are listed on the ledger. Note that when the total amount of a sub-item will exceed the entire amount of the item in the bill of quantities (or budget) When doing so, it should be carefully reviewed and approved and the reasons carefully analyzed.
10 Review and approval of construction delays and claims
(1) Review basis. Reasons and evidence for the claim, verify the facts causing the delay and claim, determine the reasons belonging to the contractor or non-contractor, and determine the responsibilities of each party according to the contract. The time limit for filing a claim shall be within the specified time.
(2) The approval should state whether the situation is true and whether the reason for the claim is established; state the number of days that will be delayed beyond the critical line of schedule, and the amount calculated according to the contract provisions and cost calculation basis.
