Five major construction estimation mistakes to be avoided at all cost

Before commencing any construction projects, the plans have to be laid down on paper to estimate the possibility of success in the project. The accuracy of construction estimates must therefore be high which is why you need to involve an expert before commencing it. Construction estimators are the professionals who figure out the amount of investment that can go into construction of a building before it even starts.

When looking for Construction estimator Australia, you should know the qualities to look for in them which include experience in construction industry, training in construction related studies and most importantly a great track record in the industry. Quantity surveyors are often mistaken for estimators, while both perform similar roles there are differences. Estimators are involved in the tendering stage of the project, before it begins. Quantity surveyors in Adelaide are involved throughout the entire project, ensuring estimates are met to keep the budget and timeline on schedule. Therefore, it would be a mistake not to have a quantity surveyor involved in the project after the initial estimation. The same way it is a failure to not involve an estimator and only a quantity surveyor. Keep reading to learn more and stop your project suffering from the following construction estimation mistakes.

Poor risk assessment 

Any construction estimation process is never complete without proper risk assessment being done. Other than helping the project owner make plans for contingencies, the estimator can pass on bid submission should the project be too risky. Risk assessment only highlights the potential things that could go astray and how the management team can lay down the necessary recovery plan for the same. It is necessary to avoid going further with the plan if the estimator says it is too risky and instead have the whole plan reevaluated.

Inaccurate takeoffs 

According to most estimators, the takeoff part of the estimate is most important because it lays the framework on how much the project will cost the project owner. Wrong takeoffs can lead to a wrong estimate which instead confuses the entire project, sabotaging its quality and safety.

The right takeoff will let you know just how much you need for labor and supplies to be used for the project and hence make the reasonable budget as needed. To make their work easier, professional construction estimators rely on technology options like takeoff software for improved accuracy. 

Cost of labor for the project 

Besides the cost of purchasing construction materials and supplies, estimators will have to determine how much labor costs should be planned for. This might just be the hardest estimate to make mainly due to varying factors like experience needed, time to be clocked in at work and rate of pay needed by the employees.

Refer to labor cost of previous recent projects for the current estimate to be correct. You also have to understand that hiring of experienced workers will mean getting the tasks done both professionally and within the stipulated time period. 

Cost of supplies and materials needed

Most estimators admit that determining the approximate amount of budgeting to be set aside for supplies and building materials is never easy to come up with. One of the reasons for the same includes the fluctuation of prices for different construction materials needed for the task.

A great estimator should therefore use updated figures from suppliers in their network rather than relying on old figures. Estimators should besides enlighten their suppliers of the exact amount needed and ascertain whether supply would be a problem or not. 

Failure to review the plan upon completion

There is no denying that mistakes are human, however the bigger mistake is to ignore the mistakes made especially with serious projects like constructions.  Minor omissions can be fathomed but not those involving failure to get the right measurements or use of the wrong measurement units.

After coming up with the estimates plan, estimators should take some time to review its details just to make sure they make sense and would work upon application. Rushing your work and failure to review them can see you turn a blind eye on so many mistakes that could lead to the failure of the whole project once commenced.
