The idea
Ten construction and contractor Excel systems — estimating, billing, payroll, compliance and project controls — in Indian and United States editions.
Site paperwork is where the money actually goes missing: an unrecorded variation, a missed measurement, a delay nobody documented, a subcontractor whose insurance lapsed. The engineers who need this will not adopt software — they will open a spreadsheet — so the spreadsheet has to be right.
What is in it
Estimating & billing
- Construction Cost Estimator (India BOQ)
- Contractor Estimate Template (bid, job costing)
- Construction Billing Spreadsheet (IS 1200, CPWD)
- Bar Bending Schedule (rebar cutting length)
Payment & compliance
- Construction Payment Tracker (retainage, change orders, waivers)
- Construction Labour Payroll (India compliance)
- Subcontractor Insurance Tracker with enforcement letters
Controls & documentation
- Construction Project Controls (EVM dashboard, delay register)
- Construction Site Documentation Pack (RFI, procurement, test registers)
- Contractor Bundle — estimating, payment and compliance together
How we are building it
Two regional editions rather than one generic set, because compliance is the entire value and a generic labour-compliance sheet is worse than none: it gives false confidence in exactly the document an audit will open first.
What is being built
- Estimating and job costing, with a BOQ bid calculator
- Billing to IS 1200 and CPWD, and a payment tracker with retainage and change orders
- Bar bending schedules with rebar cutting lengths, to IS 456 and IS 1786
- Labour payroll and compliance for Indian sites; COI expiry and enforcement letters for US ones
- Project controls with an EVM dashboard and a delay register
- A site documentation pack — RFI, procurement and test registers
