Multinational Regional Headquarters, Airport City Accra
Specification-grade engineered hardwood across executive boardroom and C-suite floors paired with mirror-finish polished concrete across reception and circulation. Coordinated multi-system installation under a single project office for a Tier-1 multinational regional headquarters in Airport City.
Project Profile
| Field | Detail |
|---|---|
| Sector | Multinational Corporate Headquarters |
| Scale | 1,800 sqm across executive boardroom, C-suite offices, reception court, and principal circulation |

| Timeline | 8 weeks, phased against the building’s broader fit-out programme |
This commission covered the executive and reception floors of a multinational corporate regional headquarters within Airport City, Accra — a programme requiring the visual register of a Tier-1 institutional interior delivered to the construction-grade timeline that multinational corporate fit-outs invariably impose.
Specification Challenge
Multinational regional headquarters fit-outs operate against compressed programme windows and uncompromising specification briefs. The floor was required to deliver two distinct visual registers across a single building: the warmth and acoustic register of engineered hardwood across executive zones, and the contemporary mineral register of mirror-polished concrete across reception and circulation — with deliberate transition detailing managing the threshold between systems without visible interface.
Two technical demands required engineering before installation could commence. First, substrate flatness across the reception court was outside the FF35 tolerance required for the polished-concrete mirror finish to deliver consistently across the field. Second, the engineered hardwood specification required documented acclimatisation in a controlled-humidity environment that the active construction site could not naturally provide — a temporary humidification protocol was required to bring ambient conditions to the manufacturer’s specification before any board was opened.
Approach
The Floors GH project office structured the engagement in three documented phases, each with multi-stage QC sign-off before progression.
Phase 1 — Substrate Preparation Across Both Systems. Following ASTM F2170 moisture verification, the reception court substrate was brought to FF35 tolerance through specification-grade self-levelling compound. The executive-zone substrate was diamond-ground to ICRI CSP grade for the engineered hardwood underlayment system. Substrate handover was signed off in writing before either system advanced.
Phase 2 — Engineered Hardwood Installation. Specification-grade engineered hardwood was acclimatised in-room under the controlled-humidity protocol, with ambient readings recorded daily across the acclimatisation window. Boards were laid in a straight pattern across the boardroom and herringbone across the C-suite reception, with expansion gaps maintained to manufacturer tolerance and skirting transitions planned for invisible interface.
Phase 3 — Polished Concrete to Mirror Finish. Across the reception court and principal circulation, progressive diamond grinding stepped through coarse-bond, intermediate-grit, and fine-bond tooling. A lithium-silicate densifier was applied at the specified aggregate-exposure stage. The final polish brought the surface to specified specular reflectivity, with the threshold to the engineered-hardwood field detailed as a flush brass divider strip flush with both planes.
Outcome
- FF35 floor flatness compliance documented across the reception court before polished-concrete commencement
- Engineered hardwood acclimatisation log filed with manufacturer-required ambient readings across the full acclimatisation window
- Polished concrete specular reflectivity measured to specification across the reception and circulation field
- Threshold between engineered hardwood and polished concrete delivered as a flush brass divider visible only at the material transition
- Programme delivered within the eight-week construction window with zero coordination conflict against the building’s broader fit-out
- Written guarantee issued covering installation integrity across the full 1,800 sqm programme
What This Project Demonstrates
Multinational corporate headquarters fit-outs in Airport City represent one of the most coordination-heavy intersections in Ghana’s specification flooring market: two distinct premium systems, deliberate transition detailing, compressed programme, and specification documentation aligned to the fit-out’s broader QA regime — all delivered under a single project office responsible end-to-end.
Floors GH has operated in this register since the practice was established 1972. Coordinating multi-system installations under a single project office — with substrate, transition, and warranty documented as one programme rather than orchestrated across multiple specialist installers — is the specification advantage Tier-1 multinational clients commission this practice for. Where Ghana’s premier institutions step, the floor beneath them has been placed with this level of care.
Outcome with Measured Impact
The completed installation delivered 740 m² of European oak engineered hardwood with 5mm wear-layer veneer and oil-finish surface treatment across the regional headquarters’ principal floors, executive suites, and boardroom prelude. Post-install verification at 18 months: surface integrity holding at handover spec (no warpage, no veneer delamination); operations-team feedback confirms executive-floor warmth and acoustic properties as specified at design phase.
Cost-per-square-metre-year analysis (planned versus actual at 18 months) tracks materially favourable against the carpet alternative the original brief considered — maintenance burden reduced approximately 40%, replacement cycle extended from projected 5-year carpet refresh to anticipated 25-year hardwood refresh.
Why This Project Was Specified to Floors GH
The multinational’s regional facility director had inherited a procurement cycle that had previously favoured price-led contractors for finishing work. The 2025 brief explicitly required institutional-grade specification with documented warranty, training-of-staff component, and integration with the corporation’s global facility management framework. Floors GH was selected for documentation continuity matching the global FM framework, the ISO 9001/14001/45001 certification triad, and the project-office model with named senior specialist accountability.
