Material Estimation Tools

Quotr.ai is an AI-powered construction technology platform designed to modernize the pre-construction workflow for subcontractors, general contractors, and developers. It serves as an all-in-one workspace that replaces manual spreadsheets and fragmented documents with a streamlined, automated system, transforming static construction drawings into actionable data so firms can move from uncertainty to execution in minutes.

SizeTheJob builds fast, accurate construction-materials calculators that answer one question before you spend money: how much do I need? Free, no sign-up, and every page shows the math. Every calculator runs on one shared, unit-tested math engine. For bulk materials it computes the volume of your area (length × width × depth, with shape options for circles, triangles, and L-shapes), converts to cubic yards (1 yd³ = 27 ft³), and applies the material’s density to estimate tons and bags.
