Office floor renovation: deliver in 12 weeks, budget locked in

A Kytom mission is an end-to-end commitment: technical audit, costed programming, APD/DCE design, managed execution and OPR handover, all under a single enforceable fixed price. You sign with a single point of contact, you receive a firm quote within 15 days, and you get a floor delivered in compliance with the regulatory requirements applicable to workplaces (R4213 standard), the environmental requirements in force on extensions, and the targeted threshold.

Across 47 floors delivered between 2022 and 2024, we measure compliance with the fixed price at 98% and an average lead time of 12 weeks on the typical 700 to 1,000 sqm area. The fixed price buys interface responsibility: disputes between trades (raised floor sealing versus power systems, insulation versus suspended ceiling) that generate 14 to 22 days of downtime with separate work packages are absorbed by us. For the CFO, this means a CAPEX of 400 to 1,200 EUR/sqm excl. tax, scheduled and amortisable over the lease term, without the unforeseen 12 to 18% change orders common elsewhere.

Our method sequences five phases contracted from signing. Phase 1, technical and usage audit: surveyor’s measurements, asbestos/lead diagnosis for pre-1997 buildings, energy audit dedicated to tertiary buildings, observation of flows over 5 to 10 days. Phase 2, programming: space planning, workstation ratios, phygital scenarios delivered within 15 days with a firm budget. Phase 3, APD/DCE design in 3 weeks, integrating operational environmental standards or WELL where the asset warrants it. Phase 4, managed execution by a dedicated Kytom site supervisor, in occupied premises (night work, phasing by 200 sqm) or vacant premises, with weekly reporting to the steering committee. Phase 5, OPR handover, clearing of reservations within 10 days and 12-month after-sales service across all work packages.

The design and build model concentrates responsibility on a single point of contact, which structurally reduces interfaces, coordination times and change-order risks compared with an organisation in separate work packages. On a 700 to 1,000 sqm floor, this approach generally allows for faster delivery and better control of the initial budget envelope, two levers directly readable on the CAPEX validated by the executive committee. MEP coordination beneath the raised access floor (100 to 300 mm), which houses air distribution, power, VDI and condensate drainage, remains a critical engineering point entirely managed by your Kytom project manager.

Our internal measurements quantify the gap between design and build and separate work packages on the key indicators of a tertiary renovation operation: fixed-price compliance, delivery lead time, post-renovation energy performance and share of floor space reallocated to collaboration. On these four dimensions, the integrated Kytom model significantly tightens the dispersion observed with separate work packages, while securing the regulatory trajectory applicable to tertiary buildings.

On an 850 sqm floor, these gaps translate into cash: the weeks gained on the schedule represent rent avoided, directly recovered on the operating account. Budget control also avoids the common 12 to 18% change orders that erode project profitability and the use of the CAPEX validated by the executive committee.

1. Technical and usage audit
   Over 5 to 10 days: surveyor’s measurements, asbestos/lead diagnosis for pre-1997 buildings, energy audit dedicated to buildings and observation of user flows. This phase produces a costed assessment that secures the following decisions and avoids 90% of unpleasant site surprises.
2. Programming and fixed-price quote
   Within 15 days after the audit: space planning, workstation ratios, collaborative zones and phygital scenarios, with a firm contracted budget. The CFO has an enforceable estimate, not a range. This is the step that locks in budget compliance at 98% measured across 47 floors.
3. Detailed APD/DCE design
   In 3 weeks, architects and engineering firms produce execution drawings, technical specifications and bill of quantities, integrating the environmental and usage-quality standards suited to the asset. MEP coordination beneath the raised access floor is handled at this stage to avoid site interface disputes.
4. Execution and OPR handover
   A dedicated Kytom site supervisor manages 8 to 10 weeks of work, phasing by 200 sqm and night work if premises are occupied. OPR and clearing of reservations within 10 days, 12-month after-sales service on all delivered work packages.
