Estimating and Quantity Analysis Tools

As a result of 3D design tools users are expecting the construction project estimator as a by-product to maintain the quality and productivity. For an estimating solutions the actual factor should be considered.

Causes that affects productivity

Necessary instructions, materials and equipment's needed should be accounted in the estimate.

Because of these factors estimating software fails to meet their users requirement. 

Project portfolios, especially for large construction firms, are incredibly diverse. General contractors have an increasing number of model-based projects, with the majority of projects still based on 2-D plans. In fact, even for projects that include a 3-D BIM model, construction components are often missing from the model, resulting in the need to perform a hybrid of both 3-D and 2-D quantity takeoffs.

Multiple inputs require separate tools for a 2-D takeoff versus a 3-D takeoff. These tools often act independently of the estimating software that will ultimately need to consume those quantities. In addition, separate takeoff tools require the estimator to learn multiple systems, each with their unique user interface workflows.

Compounding the issue, these tools often depend on a cost library specific to the takeoff tool. One can see the complexity and redundancy: a cost library for the 2-D takeoff solution, a cost library for the 3-D takeoff solution, and in most cases an entirely separate cost library for the actual estimating software. In other words, every time there is a material price update, someone has to update that price in as many as three separate cost libraries.

Thankfully, technology advancements are coming to market that eliminate this unnecessary complexity. The most robust tools combine best-of-breed estimating and takeoff solutions to help estimators increase efficiencies, win more work and maximize the profitability of projects.
