01
Project costs are easily inflated when there is an oversight on important cost components like fittings, accessories, or the work of installing these components. These unforeseen expenses lower the profitability and cause strain in the budget in the course of implementation.
02
The wrong calculation of quantity or deficient planning may result in shortages of materials and incompatibility of schedules. Late equipment delivery and employee mismanagement slows down the installation process and influences the entire construction process.
03
Improper estimating may lead to wrong equipment sizing or bad planning of the system. This has a direct effect on the efficiency, performance and reliability of the system following installation.
04
Overestimating results in waste that is not necessary whereas underestimating results in delays as a result of reordering. Both cases are costly and disruptive to workflow.
05
Failure to comply with code requirements or inspection standards may lead to failure in approvals, rework and high expenses incurred in the project due to delay. In the Canadian construction projects compliance is very important.
06
The performance, delays and cost overruns decrease client confidence. This does not only influence the project at hand but could also influence the business prospects in future.
