More about our Sydney Construction Estimating process

Newin Building Estimating Services in Sydney aims to ascertain the cost of materials and labour based on the proposed project design and specifications. Using current market rates derived directly from subcontractors and suppliers including company historical data. We can compile an accurate construction cost estimate on what the project building cost will likely be. This will enable our clients to either up or down spec based on their budget requirements.

Unless other agencies we don’t use cost guides

Our expertise in the Sydney market allows us to rate up our estimates based on the project geographical location. For example, there is a major price difference due to local contractors and level of finish say for a project in Blacktown compared to a building project in Bondi. Our philosophy is you are only as good as your rates. So every construction cost estimate we produce is based on real local data and on the specific requirements of the building project. Not generalised cost guides like Rawlinsons or Cordells which we find can make the building costs vary considerably.

We highly recommend our clients use our services as construction estimators in the concept stage of the project. This will ensure that the proposed preliminary design fits within their client’s budgets requirements. As construction estimators and our in-depth knowledge of the Sydney area. We can estimate the structural / foundation likely costs and can be accurate within 15% of actual costs once the full project documentation is developed. This will give our clients confidence in either going ahead with the current design or modifying it to suit budget requirements.

There is an inherent danger of providing a typical square meter rate for the intended building project. Factors such as foundation material, site access, specified materials and engineering/council requirements can blow out the cost quite quickly. This is why we recommend engaging a construction estimator to provide an in-depth analysis of the actual costs for the project.

If the full project documentation has been completed and the intended costings have gone way over budget. As construction estimators, we can perform a value engineering exercise as like Quantity Surveyors would do. We would study the project construction costings as a whole and recommend what alternative materials/structures can be utilised to reduce building costs as much as possible without comprising the intended scope of the design.
