Quality Control
Quality control is the periodic inspection to ensure that the constructed facilities meet the standard specified in the contract. It is usually carried by team of owners engineers or its morning. As for example, in a high way project, engineers check that compaction of soil is carried out properly by measuring its density; workability of concrete is checked by employing slump test etc. or checking compressive strength of concrete at periodical level.
Quality assurance is good management scheme whereas quality control is an inspection or sampling process.
Government works is generally carried out using lowest bid system. In lowest bid system, high quality work carried out by contractor does not play a major role rather price quoted by them is an important criteria.
The procedure for selection of contractor affects the quality control in the construction. Low bid system hardly provides any incentive to high quality work carried out by the contractor. Government organizations are highly their hard to improve the low bid system.
Quality control includes
- Setting up specific standard for construction
- Checking the deviation from the standard
- Taking action to correct or minimize the variation
- Improvement of the standard.
