CONCRETE FLATWORK: THE 72-HOUR FLATNESS CLOCK

The 72-hour rule usually decides it. ASTM E1155 requires measurement within 72 hours of final troweling, before loads and partitions distort the slab. A timely, documented test is the finisher's acceptance record. A late test measures what the building did to the slab after placement. Commission the test, bill it as a line item and keep the report.

FF measures flatness (short-range bumps over roughly 2-foot intervals). FL measures levelness (slope over roughly 10-foot intervals). Both are computed under ASTM E1155 from profiler readings. A floor can be smooth but tilted (high FF, low FL). Specs state both, often with minimum local values, so a passing average can't cover up a failing corner.

Three tiers, and which one you are in depends on how much of the work you want off your desk. On Core we build your plan every month and your team does the work: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. On Strategic we build the plan, track it and adjust it every month: our team does the bookkeeping and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. On Platinum we manage the money side for you every week: our team handles your bills and receivables the way an in-house controller would, and you approve every payment. We don't do payroll.

Sixty days. We migrate your books back to the start of your last taxable year and build your job costing structure from scratch, and on Strategic and Platinum we set up the job costing and WIP software too. You're fully up and working in two months. The onboarding fee is one time, the same for every tier, and set by your revenue band.
