WHAT IS QUALITY IN CONSTRUCTION

What is quality


Quality is some sort of a multidimensional aspect. As the perception changes so is the way quality will be seen for different people. There is no universally accepted definition on quality as a reference. sometimes objective and sometimes subjective. The best one today can find a challenge with even better-quality definition on the next day.

So, let’s talk about the quality of civil construction primarily as this qualityandconstruction.com is an exclusive place for civil engineers and for others those who are involved with civil construction. Assuming a scenario from some real-life incidents – if not for all but at least for few people out in the universe for sure – may make it simple for knowing the importance of Quality during construction works. Everyone has a dream of having an own home even at the cost of life long earning and savings. Many lucky ones materialize that dream and owns one.

A real life scenario of bad quality


Imagine one fine day while enjoys a monsoon, water droplets are falling on your head, or in the dining table or on another day when one wants to go for an urgent work suddenly experiencing chocking of water lines in a recently owned home. Both the cases frustrate everyone. And what could have been reason for these, in layman’s language the quality of building is bad” or in simple terms it must be because the ‘’construction of the building failed to meet the standard’’ that it would otherwise have to or in technical terms a proper quality system to supervise or monitor the works has been absent” from the contractor while the works being executed.

The roof slab leak maybe due to substandard quality of material (Concrete) used, or due to the incompetent supervision or may be the combination of both. The second case of problems in the pipelines may be because of untested/un-commissioned plumbing works of the buildings before it handed over for use. All of this points to the importance of Quality control and Quality Assurance while the construction is in progress.

The problems related to Quality Control in construction is not limited to these two cases only. As there are several activities in civil construction or any construction the probability too is high unless the quality of these works is not monitored, supervised with a plan in place.

The difficulties to face for substandard quality


Rectifying such damages on buildings are much more complex than making the original structure in its first place, be it any type of construction let alone civil but other trades like mechanical, electrical, firefighting, telecommunication etc. Apart from the hardships on the corrective actions it ultimately cost more money and time which are the most two critical components of all projects in across the globe.

Quality is not vague or subjective, judgement and opinion have no part in the measuring of and determining of quality. The words like “high quality”, “smooth” or even “satisfactory” do more to confuse all those involved than clarify what is required. Consider it is specified as flat or reasonably vertical, it does not categorize as a quality criteria and the requirement cannot be met. without reasonable interpretation and impossible to evaluate the actual performance. But instead it should be stated like “a tolerance +/- 3mm for 6m is allowed for vertical measurements.

Impacts of substandard quality in construction

So, it is easy to realize now that quality control and quality assurance remains as the top priority in construction. If not, then WHY IT SHOULD’NT BE? There could be many attributes which are direct and sometimes indirect that could have the possibility of bearing the brunt due to the degree of. Some of them are,


quality in construction time

Time: 

Any rework on an already completed item, arising out of non-conformance against the approved details, specifications and/contractual requirements result in extremely time-consuming activity for the project.

quality in construction reputation

Reputation:

A service or a product that comes with quality always gets a thumbs up from its users creating confidence on them. And the opposite will happen if it is of bad quality.
