Four values that hold up on site
Four values only mean something if each one translates into a quantified contractual deliverable: otherwise it is just communication. At Kytom since 2006, every value is backed by an enforceable indicator (NF S 31-080:2006 on acoustics, article 1792-6 of the French Civil Code on after-sales, change orders signed before execution). For a CFO or an Asset Manager, this is what separates an auditable commitment from a marketing promise: our commercial projects run on average over 12 weeks for surfaces around 850 sqm, for spaces designed to withstand 8 to 10 years of intensive use. The four pillars below (proximity, rigour, deadlines, transparency) follow one principle: no value without an indicator, no indicator without a contractual clause.
Operational proximity: 11 branches, response within 24 h
For the multi-site Asset Manager, proximity is not measured in kilometres but in hours lost coordinating centralised management. The Kytom network covers mainland France and Barcelona, with each project manager operating within their assigned territory.
- Territorial coverage: 10 branches in France and 1 in Spain, with each project manager operating within their assigned territory.
- Salaried site managers: no subcontracting of management, daily on-site presence during the works phase.
- Approved local craftsmen: a panel of 180 audited finishing-trade SMEs, direct contracting without intermediaries.
- After-sales response time: 24 to 48 working hours under the warranty of completion (article 1792-6 of the Civil Code).
- Personalisation: the client’s fit-out standards documented and replicated site after site, framing adapted to its internal processes (approval, security, procurement).
Asset management perspective. For a multi-site portfolio spread across the country, centralising through a main contractor generates a logistical coordination burden that is non-billable on the property management side. Territorial management transfers this burden to the local Kytom branch, which shows up in property management OPEX, not as a quote line.
Contrarian position: proximity does not replace coordination. Eleven offices only have value if execution standards stay identical from one territory to another: installation references, reporting and quality control are managed nationally, precisely so that proximity does not produce eleven different levels of quality.
Quantified rigour: acoustics, RE2020, ERP compliance
Acoustic lining left out of the tender documents generates post-delivery rework whose cost far exceeds that of initial integration: rigour is not a posture, it’s a total-cost calculation. Three families of constraints structure the choices in French office fit-outs.
| Domain | Reference standard | Target indicator |
|---|---|---|
| Open space acoustics | Applicable office acoustic standard | DnT,A >= 35 dB partitions, rT <= 0.5 s |
| Energy performance | Environmental regulation in force (major renovation) | Bbio, Cep, DH capped |
| Fire safety | Labour Code R4216, ERP type W | Smoke extraction, emergency lighting, fire hose reels |
| Lighting | Indoor workplace lighting standard | 500 lux administrative workstations |
Decisions are made during the preliminary design phase (APS), never during the works phase. Kytom refuses three types of compromise: personal safety, regulatory compliance, and execution quality on the technical lots (HVAC, high- and low-current electrical, plumbing). Savings are sought elsewhere: space optimisation, furniture reuse, choice of finishes.
Architect / IRB perspective. The triptych of acoustics, energy performance and ERP safety cannot be settled during execution. A single-skin 72/48 partition delivers a DnT,A of 32 dB; a double-skin 98/48 partition with 45 kg/m3 mineral wool reaches 38 to 42 dB. The 6 to 10 dB difference is decided in the tender documents, not at installation. The same applies to rT: a class-A mineral suspended ceiling vs a non-absorbent vinyl floor tips a meeting room between 0.4 s (intelligible) and 0.9 s (uncomfortable). The IRB’s role is to impose these choices before the contractor consultation.
Contrarian position: the doctrine of the maximum standard is not our reading. The fit-out profession tends to apply the « high-performance » level of the office acoustic standard by default, regardless of actual density. On a floor < 150 sqm single-occupant or a non-ERP space undergoing a simple refresh (painting, soft flooring, no HVAC modification), this overkill generates a partitioning overcost of 15 to 25% that is unjustified relative to the use. The Kytom method consists of imposing only the framework that genuinely applies, not the maximum standard: this is a reading that departs from the majority practice of acoustic engineering firms.
Firm contractual deadlines: dated milestones, shared critical path
An announced deadline only has value once it is milestoned in the contract: each phase carries a dated deadline, validated by the client and tracked in site meetings. Kytom structures every project into four binding phases.
- Design phase: concept, detailed design and tender documents against dated milestones, formal client validation.
- Tender phase: separate trade packages or general contractor, documented comparative analysis.
- Works phase: 12 weeks average lead time for 850 sqm of fitted space.
- Pre-handover phase: preliminary operations at 8 days, snag-list closure within 30 days.
Schedules build in three realistic margins: lead times verified with manufacturers (partitions, suspended ceilings, custom furniture), administrative timeframes (works authorisation, safety commission review), weather contingencies on façade packages. A Kytom schedule contains no hidden buffer weeks: transparency on the critical path lets the client arbitrate in real time if an option extends the deadline.
CFO / Asset Manager takeaway. A one-month delay on an office delivery means 30 days of double rent (former site plus future site under lease commitment) or 30 days of lost rent if the incoming commercial lease has already started. On an average-sized asset at EUR 320/sqm/year, the monthly stake amounts to between EUR 18,000 and EUR 25,000. This is precisely why the schedule is contractually milestoned and transparently tracked: trade-offs are made upfront, on the critical path, never at the end of the project as a fait accompli.
Contrarian position: no serious schedule absorbs administrative timeframes. On projects requiring public-access works authorisation with a safety commission review, the processing time (4 to 8 weeks depending on the prefecture) cannot be managed by the contractor. Promising a global date that includes it means selling a risk: Kytom announces it from the tender stage and isolates it from the execution schedule in the contract terms.
Contractual transparency: itemised quotes, change orders signed before work starts
A change order signed after the work is done is not a change order, it is a surprise invoice: transparency is measured when the commitment is made, not when it is paid. Kytom formalises four visibility rules on every commercial project.
- Itemised quotes: every trade package priced line by line (supplies, labour, quantities), comparable from one tender to the next.
- Change orders before execution: any change of scope is priced, justified and signed before the related work starts, never regularised after the fact.
- Contractual weekly reporting: photographed progress, milestones, blocking points and pending decisions, issued on a fixed date throughout the construction phase.
- Shared site log: meeting minutes accessible to the client, decisions traced with their date and their author.
CFO / Asset Manager takeaway. The financial risk of a fit-out does not sit in the initial quote but in change-order drift: gaps between the signed budget and the final cost mostly come from changes that were never priced upfront. The signed-before-execution rule caps that risk: the budget can only move through a documented client decision, which makes the final cost auditable line by line.
Contrarian position: total transparency is not a goal in itself. Submitting every second-fix technical choice to client approval (screw references, rail brands) paralyses decision-making and dilutes responsibility. Kytom documents everything, but does not delegate to the client the technical arbitration that belongs to its responsibility as a contractor: that boundary is contractual too.
Frequently asked questions
How does Kytom keep its deadlines?
The contractual schedule is milestoned phase by phase (design, tender, works, pre-handover) with dated deadlines validated by the client. Margins include lead times verified with manufacturers and administrative timeframes, announced from the tender stage. The critical path is shared: any trade-off that extends the schedule is decided knowingly, upfront.
Why refuse the « high-performance » level by default in the reference acoustic grid for offices?
Because applying the maximum standard regardless of actual density generates a partitioning overcost of 15 to 25% that is unjustified on floors < 150 sqm single-occupant or non-ERP spaces undergoing a simple refresh. The Kytom method applies the framework genuinely enforceable relative to the use and density, not the maximum standard. This is a reading that departs from the majority practice of acoustic engineering firms, and it is justified by the traceability of the assumptions in the tender documents.
What enforceable indicators does Kytom write into its contracts?
Four quantified reference standards govern execution: an acoustic standard threshold (DnT,A >= 35 dB, rT <= 0.5 s), article 1792-6 of the Civil Code on after-sales service under the warranty of completion (intervention within 24 to 48 working hours), article D543-280 of the Environmental Code on the sorting of construction waste, and the rule of change orders signed before execution. Each indicator is traceable in the CCAP, the tender documents or the acceptance report.
