The 10 Best Construction Calculators to Buy 2019

Reviews

When you get into the construction business, chances are you were passionate about building stuff, not math. Yet, there aren’t many industries as numbers-heavy as construction. As a construction manager, you just have to deal with that. That’s why you need a good construction calculator. They’re portable and unlike regular calculators, they’re built specifically to solve construction math problems.

There are a variety of options out there, doing a range of tasks from measurements to materials estimates. It’s tough finding the right tools to run your construction business, and construction calculators are no exception. Whether you want to choose multiple calculators or go for one will depend on what you want to get done. Here is a review of some of the best construction calculators in the market right now.

Features to Consider in Good Construction Calculators

A construction calculator is a handy tool that you would need if you’re dealing with mathematical problems on site or in your office. This tool will be useful for estimators, quantity surveyors, architects, contractors and various trades such as carpentry, metalwork, and plumbing.

Estimators
To come up with project quantities and cost estimates, an estimator also known as a quantity surveying technician has to take off quantities from architectural drawings. A calculator will be required to determine a lot of dimensions which are not indicated on the plan. For example, the length of the truss members, hipped roof rafters, diagonal bracing, staircase members, as well as areas of sloped roofs, ceilings, bulkheads, gable walls, eaves, and fascia boards. Complex calculations are also required for volumetric quantities such as bulk excavations on sloping land and filling to make up levels. With a construction calculator, you’ll be able to do these calculations much faster.

Architects
Specifications on the site have to comply with specifications on the plan. An architect will need a specialized tool to make and confirm calculations on site. A lot of mathematical problems will also arise during the course of designing and revisions.

Contractor & Tradesmen
Builders and trade specialists make a lot of calculations on site when setting out work, laying down, fixing and cutting materials. A construction mathematical calculator is a tool that will allow you to get the right dimensions, angles, and shape to put the pieces together. Precise cuts and fixing details will save the contractor a lot of money that goes to wasted materials caused by guess-estimating and out of range measurements.

With a construction calculator, you’ll get a correct estimate. Plumbers, tile installers, glass installers, metalworkers, roofers, ceiling installers, drywall installers, and carpenters will need this tool to calculate correct fixing details on site.t

That being said, if you’re looking for a professional construction calculator, you have to take a look at the 10 best construction calculators on the market. Some have more features than others. You have to get a calculator that fits your needs, for example, there are specialized calculators for plumbers, carpenters, concrete installers, and some which have multiple functions for all trades.
