Task

To create a tool that would replace Excel and manual calculations when preparing estimates and logistics plans. To make it possible for a foreman to put together a preliminary estimate in 10–15 minutes and get a list of the necessary materials, taking into account coefficients and technical standards.

Project features

A library of construction works with material consumption standards

Automatic generation of estimates from templates

Accounting for delivery, machinery loading and seasonal coefficients

Flexible configuration of the cost of works and materials

Generation of PDF reports and commercial proposals

A mobile version for foremen on site

Work stages

Analytics

Dozens of estimates from construction companies of various sizes were analyzed. The main types of work, calculation standards, seasonal specifics and typical errors were identified. The foremen’s wishes were taken into account: minimal “clickable” interaction, everything in 2-3 steps.

Design

The interface was developed with an emphasis on speed of input. An “Express estimate” mode and a detailed calculation mode are provided. The color scheme is neutral, for working in daylight on a construction site.

Development and testing

The web application is implemented on Angular + Laravel. It was tested with the participation of 5 small construction crews in a pilot region. Special attention was paid to offline access with subsequent synchronization when the network becomes available.

Results

Time to prepare a basic estimate reduced from 1.5 hours to 12-15 minutes

Improved accuracy in procurement planning thanks to built-in standards and rounding

Increased client trust thanks to the transparency and clarity of commercial proposals

The application was adopted by 11 construction crews in the first month after launch

Client review

“BuildCalc is now on every foreman’s phone. We stopped losing money due to miscalculations, and clients began to see what they are paying for. A simple and powerful tool for everyday work.”
