Quality control in construction isverification of the compliance of the materials, products, equipment and structures used with the design techniques for the production of work, the requirements of regulatory documentation, design decisions, construction dates and its cost for design estimates.
The quality of the products is compulsorily determined at each stage of the work: in the preparation of regulatory documents, design, manufacture of materials and components, production of installation.
The quality of construction and installation work mustmeet project and documentation requirements. It depends on the qualifications of engineers and workers, applied products and materials, tools and machines used, and compliance with technology.
Quality control of construction and installation works andThe adoption of operational measures to eliminate the marriage may be internal and external. The latter is carried out by departmental and state control bodies.
The customer carries out technical supervision of the quality of the works performed, their volumes, terms of implementation and accepts fully completed facilities.
State bodies of architectural and construction controlsign a permit for the production of works, track the linkage of the building to the allocated site and compliance with the rules for the performance of work. For each contractor must have a license for activities.
Author's supervision is carried out by the general design organization, carrying out quality control of construction works and compliance with the projects under construction.
Internal quality control performedevents are performed by employees and supervisory bodies of installation organizations at all stages. Builders, masters and team leaders carry out an on-line inspection of the quality of construction work continuously and continuously. They bear personal responsibility (both administrative and criminal) for violation of construction laws and compliance with production technology. The chief engineer (as the technical director of the organization) systematically performs selective (for individual objects) quality control of construction works.
Internal control consists of input, operational, and acceptance and laboratory.
The input is a quality check of the acceptedproject documentation, incoming materials, products, components and equipment. The technical department of the parent company monitors the compliance of the documentation with all the possibilities for performing the work during the project approval and obtaining the working drawings. At the same time, the quality of materials, equipment and products is guaranteed by compliance with certificates, specifications, standards, working drawings and passports. This supervision is carried out by linear engineers, customer representatives and laboratories.
Operational (separate pieces of work) controlquality of construction work carried out in the workplace - the main type of internal technical supervision. It is carried out both by the workers themselves and by the production personnel. Performed after the completion of production operations, is aimed at identifying defects and promptly eliminating them. It is implemented according to the schemes developed as part of the PPR.
Laboratory control is necessarily carried outat large volumes of construction. Special laboratories monitor the quality of incoming products and materials, verify their compliance with specifications, GOSTs, certificates and standards.
Acceptance control assesses the quality of completed structures or their individual parts, as well as hidden works.
Geodetic and metrological quality assurance is carried out by the relevant services and laboratories for the purpose of unity, reliability of measurements, accuracy.
Quality control of construction is an indispensable condition for the erection of objects, a pledge of their safety and reliability.
