The 7-Step Floors GH Project Method — with QA Checklist

Why This Method Exists

Project managers, site coordinators, and facility owners commissioning specification-grade flooring need a documented methodology that aligns the floor programme with the broader construction or refurbishment schedule, identifies the critical-path dependencies that determine whether the floor delivers on time and to specification, and gives every stakeholder visibility into the QC discipline that distinguishes a Tier-1 installation from a commercial-grade approximation. This guide is the documented seven-step Floors GH project method — distilled from fifty-four years of institutional practice and applied identically across every commission from a single-zone executive boardroom to a multi-thousand-square-metre headquarters.

Step 1 — Specification Consultation and Scope Review

The project office reviews the architect’s specification document, finishes schedule, structural drawings, and any preceding correspondence. Material selection, lay pattern, joint width, levelness tolerance, and finish register are agreed in writing. The output of this step is a written specification brief that becomes the contract reference. Stakeholder QA gate: specification brief signed by the procurement lead and by the project office before site mobilisation.

Step 2 — Free On-Site Survey

A specialist visits site to verify substrate condition. Sub-floor moisture is measured per ASTM F2170 in-situ probe protocol with readings documented at survey-grade density. Substrate surface profile is verified against ICRI CSP standards. Levelness is recorded against the project’s required F-number tolerance. Existing contamination, defects, and remediation requirements are catalogued. Stakeholder QA gate: site survey report issued in writing, with any remediation scope and cost transparently presented to the procurement lead before any further commitment.

Step 3 — Substrate Remediation and Preparation

Where the survey identifies substrate conditions outside specification, remediation is executed under documented protocol — moisture-suppression layer where ASTM F2170 readings exceed threshold, self-levelling compound where F-number tolerance is unmet, diamond grinding or shot-blasting to achieve required ICRI CSP profile. Stakeholder QA gate: prepared substrate signed off by the project office and the named site supervisor before primer or bedding application begins.

Step 4 — Material Acclimatisation and Procurement Verification

Specification-grade materials are delivered to site under sealed-pack conditions, with material grade, batch number, and conformance certificate verified against the specification brief. Where the system requires acclimatisation — engineered hardwood being the principal example — the period is observed and ambient conditions recorded daily. Stakeholder QA gate: material conformance documentation filed and acclimatisation period logged before installation begins.

Step 5 — Installation to Specification

Installation proceeds per the documented method — marble book-match laying, polished-concrete progressive grinding, epoxy multi-coat application, engineered hardwood acclimatised pattern lay, ESD grounding network and conductive coating, heritage parquet block-by-block re-laying, terrazzo divider-strip and poured field, self-levelling compound mixed and pumped under controlled water-ratio. The named project office leadership is on-site at every critical phase. Stakeholder QA gate: installation milestones signed off by the project office at each substrate, primer, mid-coat, and finish stage.

Step 6 — Multi-Stage QC Sign-Off

The four-gate quality protocol — substrate, primer or bedding, mid-coat or installation compliance, and final finish — is executed with written records at each gate. No phase advances without signed QC documentation. Where regulatory compliance is part of the brief — IEC 61340-5-1 ESD verification, ASTM E1155 F-number compliance, ISO 14644 cleanroom adjacency — independent test records are commissioned and filed. Stakeholder QA gate: complete QC dossier issued to the procurement lead at practical completion, with each gate signed off by the named site specialist.

Step 7 — Handover, Written Guarantee, and Aftercare

Practical completion is marked by formal handover: the QC dossier is transmitted, the written guarantee schedule is issued (5-year Local, 7-year ISO-aligned, or 10-year Industrial as appropriate), the maintenance schedule is provided, and the project completion report is filed. The Floors GH project office remains accountable for the duration of the guarantee, with named contact maintained for any post-handover issue or commissioning question. Stakeholder QA gate: handover documentation signed by the procurement lead and by the project office; the project enters the aftercare regime.

The QA Checklist Summary

Across every commission, the procurement lead should expect to receive — in writing — the specification brief, the site survey report, substrate remediation documentation, material conformance certificates, installation milestone sign-offs, the multi-stage QC dossier, the written guarantee schedule, the maintenance schedule, and the project completion report. Tenders that propose to deliver “specification-grade” installation without committing to this documentation regime should be evaluated accordingly.
