The organization of construction activities is mainly designed to provide technical conditions for work processes. An important role is played by logistics, which determines the effectiveness of the delivery of materials, engineering equipment, as well as finished structures to the construction site. But in parallel with the repair and installation work, a quality control process is being carried out by workers. The organization of supervisory processes covers several aspects of the project, but the main part is operational control, which monitors the compliance of technical works with regulatory requirements.
Excavation control
This is the initial stage of most construction activities, during which backfilling, excavation, trenching and embankment formation can be carried out. Also, in some cases, measures aimed at organizing drainage through permanent or temporary devices are provided. The tasks of supervisory specialists include visual verification of marks for deviations of structures and land building formations from design values. During a technical audit, operational control of the quality of work aims to determine the conformity of the geometric parameters of the trenches and pits to the indicators that were also indicated in the project. In this case, the basic technical documentation before the start of land activities is checked for compliance with the general regulatory requirements for the construction of such construction projects. The quality in this case is determined based on the steepness of the slopes in the recesses, the value of the slopes and soil characteristics.
Foundation device
After completion of the land work, the team proceeds with the construction of the foundation, the quality of which will largely determine the reliability and durability of the entire structure. Before starting the installation of the supporting structure, experts should check the soil composition at the site where the foundation is supposed to be installed. It should not contain particles of ice and snow, construction debris, fibrous and rotting elements. In the preparatory part, the operational control of the foundation determines the characteristics of the blocks or reinforced concrete structures that will be used in laying the foundation of the house. Next, the quality of the installation of building elements, the correctness of their relative position in the structure, the density of information and integrity are monitored. The final documentation on the results of the control at this stage will be a work log and a geodetic diagram.
Installation control
Construction and installation activities cover a considerable range of operations, which apply to the installation of reinforced concrete columns, girders, trusses, beam elements, floor slabs, shafts and panels. This is one of the most time-consuming and at the same time the most critical types of work. The control tasks at this stage can be divided into two parts. The first involves a thorough visual and measuring inspection of building materials and structures that should be used in the work. That is, the operational control of construction and installation works begins with an assessment of the conformity of the mentioned beams, plates, panels and other materials to the requirements of the project. In particular, specialists inspect surfaces for cracks, concrete sagging, corrosion, and grease stains.
The second part of the control of installation work is carried out after their completion.The quality of installation of structures is checked with an orientation to the position established in the design documentation. Deviations, alignment of the marks with geometric axes and the reliability of the fasteners are evaluated. At the exit, the operational quality control of installation works provides information for the preparation of an inspection certificate for hidden construction activities.
Joinery
In capital construction, carpentry events usually involve the installation of window and door block structures. Also, before installation, the qualitative characteristics of the main material are checked and its compliance with technical design requirements is evaluated. The wizard checks the accuracy of geometric dimensions, appearance and documentation about the properties of elements for assembly. In the future, operational control monitors the quality of installation operations, insulation of the blocks, the density of the fit elements and the correct position of the frames.
Control in decorating
Materials for finishing work are represented by a wide range, so this type of control considered one of the most common. Work on the external and external surface refinement can be carried out at a variety of objects, including ordinary living quarters and utility rooms. The control service must check the characteristics of the materials used and whether their qualities meet the requirements of the customer and environmental requirements. This is especially true of paints and varnishes. After finishing, operational quality control allows you to determine the technical and operational properties of the formed coating. Specialists also identify possible defects in coatings with defects and give recommendations for their elimination.
Insulation and roofing measures
Hydro, noise and heat insulation is carried out in almost every project. To one degree or another, insulation work is required both in residential buildings and in production facilities. Such materials can minimize the negative factors affecting building surfaces from the outside. Especially their function is expressed in the roofing. The basic structures of trusses with rafters and the quality of the roofing “pie” are also subject to control. Already at the final stage of the inspection, the operational control evaluates such parameters as the thickness of the insulation, primer coating, basic structural elements, etc.
Control of repair and construction work
Most often, in the process of such work, restoration of old coatings is carried out, insulation is updated, trusses and supporting structures are strengthened. Before starting work, experts evaluate the current state of the target objects. Next, a design solution for the implementation of repair measures is developed. As a result, operational control of the quality of construction work as part of the repair may include examination of the project. In the course of the analysis, an assessment is made of how the repair measures will be justified, from an economic point of view. By the way, it is the results of such control that often become the basis for declaring dilapidated buildings emergency.
Conclusion
Operational control measures are not an independent supervisory act. They are part of a comprehensive set of measures aimed at assessing the quality of construction tasks. At the same time, operational quality control of construction and installation works assumes a high responsibility, since it is during its implementation that the key factors affecting the safe operation of the facility are analyzed. For example, if low-quality concrete was used in the foundation foundation device, then after a few months, under adverse operating conditions, cracks and chips may form. These and other errors can be identified even before the facility is put into operation by the monitoring service.
