【 Weak current College 】 subcontract engineering of quality control

Summary: subcontracting engineering General Contracting engineering is an important component of the quality of subcontracting, have a direct impact on the total package of project quality and credibility of the overall contracting units. Therefore, the response to subcontract works in all aspects of the implementation of effective management. To make sure that the subcontract engineering quality and schedule to meet the requirements. In the simple analysis of the subcontract engineering conduct effective control of the content.

The so-called "sub projects" refers to construction unit signed the construction contract, because the market reasons or duration is too tight, or the construction unit of qualification limits, often need to be part of the contract or subcontract to other parts of the construction of a breakdown or partial project. Because it is part of the overall package works, once quality, progress is not effectively control the contracting units overall quality, progress, and a great reputation. How to effectively control the quality of subcontracting and progress, we believe that you can proceed from the following areas.

1. Select a qualified, reputable sub-contractors team on subcontracting service should be considered from the following

(1) construction qualification should meet the requirements of the subcontracting;

(2) the main technical and management personnel should have the relevant work experience or experience;

(3) the past performance of the subcontract teams and social reputation is good;

(4) and the Organization of past cooperation.

According to the above requirements choose 2 ~ 3 units comparisons identify subcontractors; then, the total package unit as subcontractors signed a definitive agreement to contract or subcontract. Whether subcontracting service and the relationship between the general contract, cannot be replaced by an oral agreement or an agreement in writing of the subcontracts. And as a General Contracting Organization, it should also be in subcontracts or subcontract engineering explicitly in the agreement on the scope, quality and technical requirements, duration, responsibilities and obligations of both parties and final acceptance of standards. In addition, General Contracting units onsite project Department needed to subcontract works in process for site management, site management methods such as quality control, safety inspection, construction, partial evaluation, etc., should be in the sub-contract receive confirmation or agreement.

2. Organization of subcontractors to Checkup

Subcontracts or after the signing of the agreement, the contracting entity shall promptly will subcontract the construction drawings for subcontractors, and the Organization of subcontracting units participate in the construction or project management company held by the construction drawing triage meeting. Subcontractors if for any reason cannot participate in the construction or project management company held by the construction drawing triage meeting, as a total package unit, shall require subcontractors project the project manager, technology leaders to subcontract works of design drawings for detailed review on subcontracting engineering design drawings of unclear or contradictory, listed in the list of issues, and General Contracting units consensus total package units participate in the supervision of the company or building Unit organization Checkup, the Unit review drawings found issues and subcontractors to review drawings, together with the questions raised at the trial, designer, supervisor, or the construction units (party a) give a clear reply or implemented.

Checkup, the total package unit in charge of technology with subcontractors based sub project of the construction organization plan or the construction programme for approval. Approval should be subcontracted project construction organization plan or scheme is able to meet the design drawings and Checkup and subcontracting requirements, whether you can meet the Contracting unit construction organization plan requirements (in particular the duration of a tense situation needs to be cross-cutting jobs, construction schedule is reasonable and easy to implement), is able to meet the laws and regulations and technical standards; if you cannot meet, subcontractors, require to be given improvement. To be supplemented after the construction design or construction program review recognized before consent subcontract engineering was started.

Subcontract engineering pre-construction, total package units onsite project Department should verify subcontractors team's main entry personnel, equipment. For this stage of the construction market, there are no norms in place to prevent subcontract engineering is subcontract, package unit verification subcontract the actual venue staff team and venue construction equipment is particularly important. Verification is mainly subcontracted project of the construction organization plan or the construction programme, check the site actually approaching persons and subcontractors in the construction organization plan or the construction plan set out in the consistency of the project Department personnel, practical approach of the equipment and the construction organization plan or the construction programme of construction equipment in the configuration are the same; if there are inconsistencies, package unit site management should be promptly submitted to subcontractors to carry out the rectification or make the necessary instructions, until you meet the requirements.

3. subcontracting engineering construction site management sub project, the total package units of site management should urge the technology gives the low-down, and through the quality and safety checks to subcontract the construction engineering conduct supervision and inspection.

(1) materials, semi-finished products, equipment inspection: materials, semi-finished products, equipment and quality is the basis for the quality of the project, its quality does not meet the requirements or improper selection, will directly affect the quality of the project quality accident caused even. Therefore, the total package units shall require subcontractors to select reputable reliable vendor, choose a product certification, social reputation good product, the country has requested the review should be witness of sampling.

(2) on the construction process quality supervision and inspection: the total package units of quality control personnel respond to subcontract the construction process for regular or occasional monitoring checks, checks whether the construction process by following the construction, meets the approval of the subcontract engineering the construction organization plan or the construction programme requirements, construction process quality meets the current standards and legal requirements; on important key procedures, such as pile foundations and concrete casting process, etc., the total package units should also be sent to the monitor the entire process. The need for a concealed location, total package before the covert unit's quality control personnel should participate in covert acceptance and supervise subcontracting units for acceptance of visa in a timely manner. In prisonPublisher check, if found to be non-compliant areas, in particular, the mandatory provisions, should be ordered to be rectified, the rectified and qualified before permitting entry into the next process to ensure quality risk eradication in operation during construction.

(3) on the construction progress management: contracting units shall require subcontractors under the construction organization plan of the General schedule monthly (weekly) of construction schedule and construction organization plan, ensure that the construction schedule to meet contract requirements. The actual situation as a result of the site cannot be scheduled construction or due to bad weather will not need to adjust the construction schedule for construction, subcontracting units should contact the "works" and other writing alone reported total package units should be recognized.

(4) construction supervision and inspection personnel: total package unit managers respond to subcontract the construction site construction staff do not regularly check verification, in particular on the requirements for certificates of personnel, such as project managers, technical directors, five, electricians, welders, machine operators (including pile machine operator, mixer operatives, crane operator), shelf workers, etc., you should check the compatibility of people, permit, certificate is valid. If found not to meet the requirements of personnel, subcontractors should be ordered, and will replace the deadline expires for special types of action cards sent annual examination until you meet the requirements.

(5) construction machinery and equipment used for supervision and inspection: the total package unit managers respond to subcontract the construction construction machinery and equipment used for regular checks, in particular the vertical transport equipment, should require installation, demolition programmes and qualified unit installation acceptance before use.

(6) secure and civilized construction inspection: the total package units onsite security officer dealing with subcontractors made safe technology gives the low-down, and on the construction site for regular or periodic inspection. Security checks by the construction safety inspection standards "itemized score, if there is a security risk that can immediately be rectified, to authenticate to the rectification; cannot be rectified, you should issue the security breach notice law rectification period of rectification. Rectification period ends, the inspector should review until the review.

4. subcontracting engineering completion approval subcontract works after completion, the total package units should subcontract engineering quality and technical information to check acceptance.

(1) physical quality acceptance: When subcontractors complete subcontract the entire contents of the contract, the contracting entity shall require the posting, post, fill out the project completion report, report the total package units. By their organization to subcontract engineering quality check acceptance, at the same time you should check whether the map construction, meets the approval of the subcontract engineering the construction organization plan or the construction programme requirements. On the acceptance of findings, timely rectification, until the review.

(2) completion material inspection and acceptance: subcontractors shall be adjusted according to the relevant specifications and subcontract engineering location content finish archives requires subcontracting technical data, completion of information and archives, and transferred to the Contracting unit. Total package unit technical personnel should review, check the technical information is incomplete or untrue, shall require subcontractors to add complete or fill out the real situation.

(3) construction warranty books: subcontractors to total package units delivered engineering products + should book the engineering warranty. The engineering warranty book of content should be consistent with the construction project quality management Ordinance and the explicit duration and subcontractors of the warranty.

Only the quality of the subcontract engineering and engineering technology information passed acceptance, engineering warranty book content meet the requirements, the total package units to receive the transfer of subcontracting, and subcontractors for transfer procedures and project settlement.
