A building’s journey from a paper sketch to a fully materialized object involves many ups and downs on the way. An experienced construction estimator knows that even in the case of the simplest of projects, some external factors may occur that can completely unbalance the building estimating process and consequently put a halt to the project development. Having a basic knowledge of which are these factors can prove to be extremely useful in elaborating the project cost estimate.

Firstly, geographic considerations profoundly affect the process of selecting unit bid prices. Whether your house will be located in an urban, suburban or rural setting, or on a flat or sloped terrain, determines the type of bid you may be accounted for. An urban project usually has to operate with space restrictions, a high traffic volume and limited hours for construction. In this case, it’s important to consult the availability of local resources. Residential projects located in rural settings have much less construction restrictions and more space and time available. However, in this case the purchase of materials may prove itself bothersome in terms of additional transportation, support and wage costs.

Secondly, quantity considerations are equally important since the quantity required of a given material impacts the unit cost of constructing an item. Suppliers usually provide discounts for a larger quantity; therefore, a construction estimator will help you with predictions that will allow you to turn this situation in your advantage to purchase in the beginning the entire amount of resources your project may require. Larger quantities increase efficiency as well, the contracting personnel gaining experience and expertise during the completion of the work. Opposing, small quantities are taxed much higher and don’t allow for production rates as effective as large amounts do.

Thirdly, pricing lump sum bid items can prove itself a difficult task. These items can reduce administrative costs, allowing you in the same time an increased mobility in terms of methods available. Building estimating usually benefits from lump sum items when an item of work has a definable finished product for which all the constitutive components are not entirely known. A construction estimator proceeds in defining lump sum items according to their simplest components and takes into consideration all other factors that can’t be as easily defined.

Finally, an important factor that influences the actions of a construction estimator is the degree of specialisation the work requires. Specialty things aren’t just the new items or new emerging building methods but may refer to items that are different from the large part of the work required on the project. Correct depiction is thus necessary when the building estimating is done. Examples of specialty work in a project may be landscaping, hydraulics, ceramic tiling or certain accessibility features. These commonly require the expertise and review of professionals who are fully familiar with this type of work.
