Design project management assistance

Legal framework: the MOP law, articles R4214 relating to workplaces and the regulatory obligations to reduce energy consumption applicable to the commercial property stock.

80% of a commercial project’s costs are locked in during 12 weeks of upstream studies: managing this phase is legally more decisive than the construction work itself. Yet many project owners treat it as a mere formality ahead of the tender documents. Since 2006, Kytom has mobilised 11 agencies in France and Spain to define the brief, budgets to within +/- 5% and the regulatory compliance applicable to commercial premises (workplace requirements, energy consumption reduction obligations for commercial buildings, acoustic requirements applicable to office spaces). Design project management assistance translates business needs into a technical specification, arbitrates 3 to 7 variants per project and validates financial envelopes before the first shovel hits the ground. This page details the scope, the 4-step Kytom method over 12 weeks, the measured benefits and the contractual considerations of a B2B project management assistance partnership.

The design phase legally commits the project owner under the MOP law and the regulatory provisions relating to workplaces (articles R4214-1 and following). Structured design project management assistance avoids late amendments, the cost of which can significantly inflate the works budget in the absence of upstream framing. The requirements to be addressed from the preliminary design stage (APS) onward cover several areas:

compliance with public access building (ERP) rules and accessibility for persons with reduced mobility (PMR) (law of 11 February 2005)
energy performance set out in the commercial buildings decree (-40% in final energy consumption by 2030, -50% by 2040, -60% by 2050)
acoustics according to NF S 31-080, indoor air quality and RE2020 thermal comfort
floor plate flexibility in the face of flex office, now a structuring concern in commercial projects

Our interpretation differs here from common practice: we believe that compliance with the commercial buildings decree should be addressed from the APS stage, not at the tender documents (DCE) phase. The profession’s conventional wisdom still treats the commercial buildings decree as an after-the-fact verification, whereas the 2030 thresholds condition the envelope and HVAC choices settled at the detailed design (APD) stage. Deferring this assessment generates costly study reworks between APD and DCE.

For a standard office floor area, a 10% programmatic discrepancy represents several dozen poorly sized square metres, i.e. several lost workstations, a concrete impact that project management assistance allows you to anticipate from the brief phase. Project management assistance also frames the targeted environmental certifications and the interfaces with the architect, building services engineering firm and health and safety coordinator (SPS).

The Kytom method: 4 steps calibrated to the standard lead time, APS-APD-DCE deliverables

Our design project management assistance mission unfolds in 4 contractualised steps, with weekly milestones and at least 3 steering committees.

Programmatic audit (weeks 1-3). Measured surveys, flow analysis, interviews with representative staff, sector benchmarks drawn from available professional publications.
Detailed technical brief (weeks 4-6). Surface ratios of 8 to 12 m² per workstation depending on the type of use, acoustic requirements applicable to workspaces, thermal requirements applicable to new commercial buildings, environmental ambitions, 5-year occupancy scenarios.
Managing the APS and APD studies (weeks 7-10). Cost checks by project management/supply/technical lot ratio, verification of regulatory compliance applicable to workplaces (article R4214 and following), ERP, PMR, assessment of technical variants.
Finalising the DCE (weeks 11-12). Analysis of contractor bids, award recommendations, documentary traceability according to our internal quality procedures.

The 11 Kytom agencies mobilise project management assistance experts working with Qualibat-certified architects and building services engineering firms. Each deliverable is versioned in a shared project space, with weekly reporting to the lead CFO or Office Manager. The internal library of sector ratios covering banking, healthcare, tech and consulting, built up since 2006 and updated annually, shortens programmatic decisions by 2 to 3 weeks.

When full design project management assistance is not the right answer. Below 300 m², or for a simple refresh with no change to partitioning, a full three-month project management assistance mission is not justified: the cost of assessment exceeds the potential budgetary gain and a condensed 3 to 4 week framing is sufficient. Likewise, on a lease with fewer than 3 years remaining, the APS-APD programmatic investment does not pay off and it is preferable to opt for a lighter mission focused on the DCE. Finally, when the business brief is already fixed by an international headquarters with an imposed template, project management assistance usefully limits itself to regulatory compliance and study management, with no upstream programmatic phase.

For the CFO and asset manager: budget overrun brought down to +/- 3% and a shortened schedule

For the finance department and the asset manager, design project management assistance reads as an instrument for securing CAPEX and protecting cash flow. Our experience on commercial operations of 500 to 2,000 m² shows that structured design project management assistance significantly reduces budget overruns and schedule slippage, while improving regulatory compliance from the point of submission. On a works envelope of EUR 1M, even a few points of overrun avoided amply cover the cost of a project management assistance mission.

The complete DCE significantly reduces contractor queries and variation orders, shortening the overall construction lead time. On the average area handled, the gain represents several weeks of schedule, i.e. as much double rent avoided for an asset manager managing a site relocation.

The briefs incorporate the thresholds of the commercial property regulation applicable to existing buildings, which contributes to the asset’s value in use; the orders of magnitude for revaluation drawn from our real estate broker monitoring remain to be confirmed project by project according to location and market. The HR departments of several Kytom clients have observed a noticeable drop in post-delivery turnover, consistent with the available research on the impact of quality of life at work on retention.

Limits of these gains. The measured differences assume a committed sponsor, with 3 to 5 person-days mobilised, and a brief stabilised before APD. If the project owner changes its decisions after APD, or if the target organisation remains unclear (merger underway, transformation plan not yet decided), the budget overrun returns to the level without project management assistance: the methodological framework does not compensate for upstream decision-making instability.

Contractual points of attention: best-efforts commitments, deliverables and clauses

The Kytom design project management assistance contract specifies a best-efforts commitment, and not a commitment as to the final cost, which depends on market and works contingencies. The contractual deliverables cover: a programmatic framing note signed at W+3, a detailed technical brief at W+6, an APS analysis report at W+8, an APD report with costing to within +/- 5% at W+10, a complete DCE file and a bid analysis report at W+12.

The sensitive clauses to settle at signature:

the scope of included client modifications, with 3 programmatic iterations beyond APD billed additionally (basis: EUR 850/day)
the allocation of responsibilities between project management assistance, project management (MOE) and the inspection office, with transfer of the L and SEI mission to the inspection office, type Apave or Bureau Veritas depending on the market
intellectual property of briefs and ratios: Kytom retains its library, the client holds a project usage licence
Kytom professional liability insurance covering the project management assistance mission, up to EUR 2M per claim

The 8am-6pm project hotline and intervention within 4h in the event of a site alert are included during the study phase. The sponsor designates a single point of contact (CFO, IT Director or Office Manager) available 3 to 5 person-days over the project schedule.

Frequently asked questions

What is the cost of a Kytom design project management assistance mission?

On a commercial operation of 500 to 2,000 m², the design project management assistance mission over its typical duration represents 3 to 5% of the works envelope, i.e. EUR 30,000 to 50,000 for EUR 1M of works. The return on investment is measured against the budget overrun avoided: a well-conducted project management assistance mission significantly reduces the gap between the forecast budget and the final cost, amply covering its fees.

How does design project management assistance fit in with the architect and the engineering firm?

Kytom project management assistance comes in upstream of the project management (MOE): it draws up the brief that serves as the specification for the architect. During APS and APD, the project management assistance checks the MOE choices against the brief and the target budget (+/- 5%). It does not carry out a design mission and does not sign the plans: responsibility for the design remains with the Qualibat-certified architect and the building services and structural engineering firms.

Do you need design project management assistance on a 3 to 6 year lease?

Beyond 4 years remaining and on a minimum of 500 m², design project management assistance pays off: the overrun avoided and the schedule held compensate for the cost of assessment. Below 3 years remaining or 300 m², a lighter 3 to 4 week mission focused on the DCE and regulatory compliance applicable to workplaces (article R4214) is more relevant. Kytom frames this decision in the first week of the pre-mission.

Does design project management assistance cover compliance with the energy consumption reduction obligations applicable to commercial buildings?

Yes. From the APS stage, our method addresses the obligation to reduce energy consumption by 40% by 2030 for commercial buildings over 1000 m² (Cerema, 2022), which differs from common practice that handles it at the DCE phase. This anticipation conditions the envelope and HVAC choices settled at APD and avoids study reworks between APD and DCE.

What happens if the project owner changes its brief after APD?

The contract provides for 3 programmatic iterations included up to APD validation. Beyond that, each modification is handled as an amendment (basis: EUR 850/day). Beyond 2 major post-APD modifications, the commitments to a +/- 3% budget overrun and a schedule held are no longer guaranteed: the methodological framework does not compensate for upstream decision-making instability, which we document in the limits of the mission.
