Project management assistance for handover and warranties

Handover legally binds the client from the moment the report is signed (article 1792-6 of the Civil Code). On a standard commercial floor, the handover inspection commonly generates several dozen reservations to clear before any occupancy. Three warranties follow on from one another over time:

• Defects liability : 12 months, all reported defects (article 1792-6).
• Two-year warranty of proper functioning : 24 months, dissociable equipment (article 1792-3).
• Ten-year warranty : 120 months, structural soundness and fitness for purpose of the works (article 1792).

According to the Agence Qualité Construction (SYCODÉS report on housing and commercial property, 2023), the majority of claims declared under structural damage insurance relate to the weatherproof envelope, technical equipment and finishes.

Kytom’s position, against standard project management assistance practice. The prevailing professional view treats the three warranties as an indivisible block activated in cascade. Our reading is different: most of the legal value of the ten-year warranty plays out in the first weeks after the report, not over 10 years. A poorly drafted report weakens the ten-year warranty as much as the defects liability, because judges (Cass. 3e civ., settled case law) require traceability of defects from the outset. The project management assistance effort must therefore focus on the quality of the initial report, not on spread-out monitoring.

When heavy handover project management assistance is not justified. Below 200 m² renovated or for a single work package (painting only, carpet replacement), full handover project management assistance becomes oversized: the cost of fees then exceeds the benefit of reducing reservations. In this case, Kytom recommends a streamlined mission limited to drafting the report and monitoring the defects liability warranty, without multi-package preliminary operations.

For the CFO and asset manager: the report as a financial asset, not a formality

The handover report is not an administrative document: it is a quantifiable legal asset on the balance sheet. For a CFO, a poorly framed handover exposes the company to non-provisioned repair costs that may represent several percentage points of the initial works amount. On a 1.5 M EUR operation, this can represent several tens to several hundreds of thousands of euros of unbudgeted cash outflow, drawn from operating cash the year following delivery.

For the asset manager, the quality of the report determines two value mechanisms:

• Rental valuation : a digitised as-built file and a detailed report feed buyer due diligence in the event of a sale; their absence translates into a price discount observed on commercial property transactions.
• Standards compliance : operational environmental certifications, including HQE Exploitation, require traceable handover documents; an incomplete report blocks certification renewal and therefore the maintenance of the prime rent.

The applicable normative framework governs handover conditions and preliminary operations. In practice, the detailed report represents several pages per technical work package, including photos and locations on plan. It is this documentary density that turns the report into an enforceable document, not its mere existence.

Kytom method in 5 steps, preliminary operations at 15 days and clearing at 60 days

Kytom handover project management assistance unfolds in five formalised steps, building on commercial property operations conducted since 2006.

1. Technical preliminary operations 15 days before the contractual date, with a dedicated inspector per work package (HVAC, high/low voltage, plumbing, partitions, flooring, suspended ceilings, joinery).
2. Detailed handover report, listing each reservation with location on plan, photo, relevant work package and clearing deadline set at 60 days.
3. Weekly monitoring of reservations, with a high target closure rate at 8 weeks.
4. Activation of the defects liability warranty over 12 rolling months, with 2 control visits scheduled at 6 and 11 months.
5. Transmission of the as-built file and the subsequent works file to the client, in accordance with the regulatory obligations applicable to construction operations.

The approach is part of an internal quality system and mobilises Qualibat partners. Each file is archived for 10 years, the duration of the ten-year warranty, so it remains available in the event of a late claim.

Benefits measured on supported commercial property operations

Three structuring benefits emerge from the commercial property operations supported by Kytom. The complete clearing of reservations occurs much faster when project management assistance is present from handover, avoiding costly catch-up situations. Detecting defects during preliminary operations rather than in operation generates significant savings on the overall project cost. Finally, the rigorous preparation of reports and handover files maximises the chances of effectively activating the ten-year warranty in the event of a claim, where the absence of usable documents is the leading cause of failed recourse.

For Office Managers and HR-quality of work life directors, spaces are made available without operational disruption, with an overall timeline generally met, which avoids delaying the return of employees. For the asset manager, the digitised as-built file feeds CMMS tools as well as operational environmental certification processes.

Limit of the economic argument. The economic gain is only confirmed on operations larger than 500 m² involving at least 5 technical work packages. On a single-package operation or on a floor already delivered without major reservations, the saving becomes marginal and handover project management assistance does not pay for itself: Kytom then directs the client towards a simple legal review of the report.

Contractual points of vigilance: tacit handover and mandatory structural damage insurance

Four points of vigilance structure the handover project management assistance mission.

• Tacit handover : taking possession of the premises without a formal report constitutes handover in the eyes of the judge (Cass. 3e civ.), with the same effects as signing, but without traceability of reservations. Any unframed handover of keys must be prohibited.
• Structural damage insurance : mandatory for the client (article L242-1 of the Insurance Code) on commercial property operations subject to the ten-year warranty. Its absence deprives the client of an advance of funds in the event of a claim.
• Late penalties : their application requires a dated and signed report, which sets the starting point of the contractual countdown.
• Adversarial clearing of reservations : each clearing must be recorded in the presence of the work package holder, with joint signature, to avoid disputes at 11 months when the defects liability warranty ends.

Kytom secures these four points from the preliminary operations phase, integrating a contractual checklist reviewed with the client’s notary or legal counsel.
