Construction work control

The main goal of construction control is to ensure manageability, transparency and predictability of processes when controlling construction and installation works for the customer. The activities of specialists are aimed at observing the customer's rights, the most important of which is considered to be improving the quality of work performance with rational use of invested funds in production.

Who carries out construction control? The construction control engineer (inspector) is an important intermediate link in the communication process between the contractor and the customer, an independent and unbiased expert in the field of building construction technology, structural work, construction economics and architecture.

This is a person with diverse technical experience in constructing various construction facilities, ranging from residential and low-rise construction to large infrastructure and oil and gas facilities. The main task of an independent expert is not only to detect defects in work performance, material supply and finished products, exposing unscrupulous contractors, but also to prevent their occurrence at subsequent stages of building or structure construction. The inspector is the tool that helps the customer monitor facility construction, contractor compliance with norms and rules for work performance, and also consult the customer regarding the correctness of certain design solutions adopted during work production. It is also important that the expert's instructions and requirements regarding quality control of construction materials, products and structures, installed equipment and apparatus, as well as quality control of construction and installation works are mandatory for the contracting organization.

According to SNiP 12-01-2004 "Organization of Construction Production", Construction Control Resolution 468 and SP 48.13330.2011 "Organization of Construction. Specialized edition of SNiP 12-01-2004": "3.7 The developer (customer) has the right to exercise control (technical supervision) over the progress and quality of performed works, compliance with their deadlines, quality and correct use of applied materials, products, equipment, without interfering in the operational and economic activities of the work performer...".

Thus, in accordance with the legislation of the Russian Federation, construction norms and rules and other regulatory acts, the main goals of construction control work are formulated:

• ensuring project implementation within the estimated construction cost;
• ensuring the use of construction materials specified in the construction project or similar in their properties, purpose, technical characteristics;
• ensuring project implementation within specified timeframes and scope;
• ensuring high quality of work production.

In accordance with these goals, the following construction control tasks are formed:

• checking the availability of quality documents (certificates in established cases) for materials, products and equipment used by the work performer, documented results in the incoming control log and laboratory tests;
• monitoring contractor compliance with rules for storage and warehousing of used materials, products and equipment; when violations of these rules are identified, the inspector can prohibit the use of improperly stored materials;
• monitoring compliance of operational quality control of construction works performed by the producer;
• monitoring the availability and correct maintenance of executive documentation for construction control by the work performer, including evaluation of the reliability of geodetic executive schemes of completed structures with selective control of element position accuracy;
• control over elimination of defects and shortcomings in project documentation quality identified during works, documented return of defective documentation to the designer, control and documented acceptance of corrected documentation, its transfer to work production performer;
• monitoring contractor compliance with construction control prescriptions from state supervision and local government bodies; notification of state supervision bodies about all cases of emergency situations at construction sites;
• monitoring compliance of work volumes and deadlines with contract conditions and construction schedule;
• evaluation (jointly with the contractor) of compliance of completed works, structures, engineering network sections, signing bilateral acts confirming compliance;
• control over the work producer's compliance with the requirement of inadmissibility of performing subsequent works before signing the specified acts;
• final evaluation (jointly with the contractor) of compliance of the completed construction facility with legislative requirements, project and regulatory documentation.

Construction control engineers of our company are capable of performing assigned tasks when conducting works on construction, reconstruction, major repairs, decommissioning of oil and gas industry and infrastructure facilities, as well as large civil and industrial facilities.

Inspection Control Services

For construction, reconstruction, major repairs of oil and gas industry and infrastructure facilities:

• analysis of project and working documentation for controllability and compliance with design solutions;
• checking compliance with norms, rules, as well as design solutions, documentation for equipment, materials and products used in work production; specifications for equipment and materials, as well as documentary confirmation of quality assurance system functioning at manufacturing plants;
• conducting permanent or selective incoming control at the construction site of materials, products and equipment purchased by the customer, unloading and storage of material and technical resources at the customer's warehouse or specialized warehouse operator (pipe acceptance, transportation and storage; acceptance and storage of welding, insulation and other materials, structures and equipment);
• incoming control of construction materials, quality control of used products, structures and equipment, their compliance with working and regulatory-technical documentation requirements, as well as documentary confirmation of quality assurance system functioning at manufacturing plants;
• exercising construction control over construction contractors' performance of incoming control procedures (other construction control services), timely conduct of necessary tests, availability and condition of accompanying quality documentation for materials (in construction control log), equipment, assembly units and structures received for work production at facilities. Prevention of using products that have not passed incoming control for construction and installation works;
• checking readiness of construction and installation organizations to perform work on project implementation;
• checking compliance of work production process, work quality and identifying deviations from the project, regulatory documents and technical regulations (general construction works, assembly and welding-assembly works; insulation and laying works; construction of pipeline crossings through natural and artificial obstacles; installation of shut-off valves and equipment, etc.);
• acceptance of concealed works with appropriate documentation;
• conducting comprehensive or selective quality control of contractor works within technical supervision using visual, instrumental and physical control methods; conducting tests of materials used in construction for compliance with manufacturer specifications;
• interaction with the project developer when necessary to make changes to the project and coordination of project changes if required;
• checking correctness of conclusions issued by construction contractor laboratories on non-destructive testing (including radiographic film control);
• monitoring compliance of quality services, production control, construction control services, instrumental control services of the construction contractor, implementation of prescriptions from RF supervisory bodies, local government, author supervision, construction control;
• timely identification of deviations from working documentation and regulatory documents, issuing prescriptions for elimination of identified deviations or violations;
• confirmation of actual work volumes performed by the contractor (act KS-2);
• participation in commissions for acceptance of completed construction facilities:

1. conducting hydraulic and pneumatic tests of facilities;

2. investigating causes of accidents at facilities;
