Engineers, not middlemen
Every HashBuy project is run by a degree-qualified engineer who is on site, not a contractor who subcontracts the thinking.
How we build
This page is the long version of a simple promise: everything is designed, everything is tested, everything is written down. Here is exactly what that means on your site.
The five steps
A 45-minute call or office visit. We learn how you live or how your business runs, what you must have, and what you refuse to compromise on.
Output: Written brief and budget band
Architects and structural engineers design together, so the plan you fall in love with is the plan that can be built, on budget, to code.
Output: Drawings, 3D views, fixed BOQ
A plain-language contract with the scope, the schedule, the named materials and a milestone payment plan. No hidden extras, ever.
Output: Signed contract and schedule
A resident engineer on site every day, lab tests for every pour, and a Friday report with photos, spend and next week’s plan.
Output: Weekly reports and milestone sign-offs
A joint inspection with a snag list closed to zero, as-built drawings, warranties, and keys in your hand on the date we promised.
Output: Keys, warranty card, as-builts
Testing
Every material on a HashBuy site is tested by an accredited third-party lab. The results go in your weekly report, so you see them before we do anything irreversible.
| Material | Test | Standard | Frequency |
|---|---|---|---|
| Concrete | Cube compressive strength at 7 and 28 days, slump test on every pour | ASTM C39 / BS EN 12390 | Every pour |
| Steel reinforcement | Mill certificate check, tensile and bend test on samples | ASTM A615 Grade 60 | Every delivery |
| Bricks | Compressive strength and water absorption | ASTM C67 | Every kiln batch |
| Soil | Bore log, SPT, bearing capacity and water table | ASTM D1586 | Before design |
| Plumbing | Pressure test on all supply lines before concealment | 1.5x working pressure, 24 h | Every line |
| Waterproofing | Flood test on roofs and wet areas | 48 h ponding | Every slab and bathroom |
Reporting
Every Friday, every project, since the first one. Photos, a short video, spend against budget, lab results, schedule status, next week's plan and any decision we need from you. It takes you five minutes to read and it means you never have to ask.
Illustrative. Real reports include photos, video and attached invoices.
Standards
Every HashBuy project is run by a degree-qualified engineer who is on site, not a contractor who subcontracts the thinking.
A bill of quantities with named brands and a contract that only changes when you ask it to. The number you sign is the number you pay.
Concrete cubes, steel certificates and brick crush tests for every delivery. Results go in your weekly report.
Photos, videos, spend-to-date, schedule status and next week’s plan. From Lahore or London, you always know.
Our contracts carry a delay clause with a daily penalty we pay you. That is how confident we are in our programmes.
Twelve months on finishes and a long-term structural warranty, with a named engineer who answers the phone.
Helmets, harnesses above two metres, edge protection and a trained first-aider on every site. A NEBOSH-certified manager audits monthly. We send workers home with the same number of fingers they arrived with.
Twelve months on finishes and workmanship. Long-term structural warranty on foundations and frame. A named engineer you can call, not a help desk.
Our contracts carry a daily penalty paid by HashBuy if we miss the agreed date. Exclusions are written down and limited to weather, force majeure and client-caused delay.
