Office Fit-Out in Muscat: How Design & Build Delivered a Head Office in 100 Days
TANMIA's 1,400 sqm corporate head office went from bare shell and core to a fully finished workplace in 100 calendar days. Here is what makes that speed possible — and what it requires.
The brief
Oman National Investments Development Company (TANMIA), a leading Omani private equity and asset management firm, needed a 1,400 sqm corporate head office in Muscat that reflected its investment-driven identity — delivered fast, from a bare shell-and-core floor plate.
Why shell and core is the hard version
A shell-and-core handover means no ceilings, no flooring, no air conditioning distribution, no partitions — every system the office needs has to be designed, approved, procured, and installed. In a conventional model, a design consultancy produces drawings, a tender process selects a contractor, and procurement starts only after award. Each seam between organisations adds weeks.
What 100 days actually looks like
Under one design-and-build roof, the sequence overlaps instead of queuing. While detailed design of the CEO floor was being finalised, long-lead items — joinery, stone, light fittings — were already in fabrication through RVI's international procurement network. Site works began on the areas whose design was frozen first: lift lobby, reception, then open workstation areas, then executive offices.
The result: lift lobby, reception and lobby, workstation areas, and CEO office delivered as one coherent workplace — functional planning with bespoke corporate detailing — in 100 calendar days from site start to handover.
What it requires from the client
Speed is a partnership. Decisions on the critical path — material approvals, brand elements, executive layouts — need answering in days, not committee cycles. A single point of accountability on the delivery side works best when matched by a clear decision-maker on the client side.
If your organisation is planning an office fit-out in Muscat against a hard deadline — a lease event, a launch, a relocation — the programme conversation should happen before the design one.
