Accuracy and precision: Enables precise measurement and calculation of materials and quantities, reducing errors in estimates and improving project costing accuracy.
-
Efficiency: Streamlines the process of quantity takeoff, saving time compared to manual methods and enabling quicker turnaround on bids and estimates.
-
Scalability: Scales with project size and complexity, accommodating the needs of both small-scale and large-scale construction projects.
-
Cost savings: Helps in identifying potential cost savings by accurately estimating materials, reducing wastage, and optimising resource allocation.
“I recently signed up to Chalkstring and I tasked myself with measuring up a drawing for a job my dad has been pricing. I wanted to compare my measurements with what he got from manual takeoff. He was about 20m² off, so I had him measure it again.
He got closer, but it took him a lot longer and still lacked the accuracy of Chalkstring. Now, he's asking me to use Chalkstring for every job!"
