Construction Nest is independently operated and developed by Haris Farooq. I research construction calculation methods, develop calculator logic, test results, and create supporting guides and educational content. Where appropriate, I also seek practical feedback from experienced masons, laborers, tradespeople, and others involved in construction work.
Every tool and educational guide published on this platform follows a strict 4-point verification lifecycle to ensure field contractors, masons, and homeowners avoid costly material overages.
Formulas cross-referenced against ACI 318, ASTM volumetric standards, and NIST wood density charts. Zero proprietary black-box calculations.
Practical consultations with experienced masons, framing contractors, and laborers to calibrate real-world jobsite waste allowances (5% to 15%).
Custom client-side JavaScript architecture delivering sub-second recalculations, dynamic 3D diagram rendering, and instant print/PDF export.
Regular post-publication formula reviews against regional building codes, lumber quarter-sawn yield rates, and batch mix concrete weight ratios.
Learn how technical articles and computational calculators are drafted, checked, peer-reviewed with field trades, and published.
Formulas from engineering textbooks often assume perfect mathematical conditions (e.g., zero subgrade settlement, 100% lumber yield). Construction Nest bridges theoretical math and actual jobsites by integrating practical trade feedback.
All calculation logic utilizes double-precision floating point math with explicit unit conversions (inches, feet, yards, meters, millimeters). Every calculator page exposes the raw mathematical formulas directly beneath the tool.
I leverage modern computational intelligence to run high-speed regression tests, generate SVG architectural schematics, and parse regulatory documents. However, all calculation logic, core algorithms, and publishing decisions are strictly written and verified by Haris Farooq.
Calculators on Construction Nest are designed for preliminary estimating, purchasing budget planning, and educational cross-checks. They do not replace stamped structural engineering drawings or certified geotechnical reports.
Production-tested web tools developed and maintained by Haris Farooq for rapid field takeoff calculations.
Calculate cubic yards, ready-mix truckloads, pre-mix 60lb/80lb bags, rebar grids, and cost estimates for slabs and footings.
