Quality control construction site

The number and severity of fabrication and installation deficiencies are also directly related to quality control efforts during construction phases of a project. For example, a review of contractor submittals, or shop drawings, usually helps assure comphance with contract documents before equipment is delivered to the job site. Site inspections during installation work may detect deficiencies in design or workmanship before they lead to operational problems and performance difficulties. In addition, specific operating and performance testing as a prerequisite to final accepfance is a key element in assuring that a system is installed properly. 

Construction Material and Labour Costs. In the Australian context, reduction of site labour costs for fabrication or construction is important, owing to the relatively high influence on project execution costs that labour exhibits when compared to materials. This applies not only for direct labour, but also to indirect labour required for adequate supervision, quality control and safety management at the workplace. Hence it is common for infrastructure to be fabricated as Pre-Assembled Modules (PAM) in a location where such labour is more cost-efficient. The need for pre-assembly of structures also tends to drive designers towards size and weight-efficient steel assemblies, rather than concrete or other materials, in order to reduce freight costs. 

The amount of testing that has to be carried out on site as part of the constructor s overall quality control process will depend on the nature of the structure and the construction process. If the units are delivered to site with a certificate confirming that their dimensions are within the specified tolerances, only critical dimensions need to be...

All nuclear power plant components are factory fabricated to reduce costs and enhance quality control. The components are assembled into fully transportable modules for transport to the site by barge, rail, or by truck. Assembly of modules at the site reduces construction time and costs. Similarly, modular components for the non-safety grade balance of plant can be factory fabricated, and quickly assembled at the site or they can be the responsibility of local companies. 

A determination that stormwater controls are not necessary based on either (A) Total Maximum Daily Load (TMDL) approved or established by ERA that addresses the pollutant(s) of concern for construction activities or (B) For non-impaired waters that do not require TMDLs, an equivalent analysis that determines allocations for small construction sites for the pollutant(s) of concern or that determines that such allocations are not needed to protect water quality based on consideration of existing in-stream concentrations, expected growth in pollutant contributions from all soruces, and a margin of safety. 

The modification method for soil removed by the sealed digging technique is now widely used. Future developments are anticipated. In order for this technique to be accepted more widely, it is necessary to develop auxiliary techniques to use soil removed from construction sites. Needed, in particular, are construction management and quality control, including the amount of additives added and mixing method used, as well as standardization in selection of additives and amount of additives. It is hoped that these problems can be solved based on actual use of materials and techniques.
