Business Engineering/Transition Management/Mandate · Documented exit

Operating Partnerinterim facadeexecutive.

An Operating Partner enters a company in the envelope industry, takes operational command over an agreed perimeter, decides, executes, and withdraws once the objectives are met. This is not a consultant, it is an interim executive who assumes operational responsibility, not the production of a report. Operating partner construction work as we practise it applies to situations where the company or the project can no longer move forward with the leadership resources in place. The mandate is contractualised with explicit operational authority, framed perimeter, measurable objectives and exit date known from kick-off.

01· Plate, three distinguishing dimensions

The definition.

The Operating Partner is an interim executive who carries explicit operational authority, on a contractualised perimeter, to reach objectives defined at kick-off. They do not produce a report, they deliver a transformed operational situation.

§ 01Responsibility

They decide, and they own. Difficult arbitrations, restructuring a team, renegotiating a tense contract, enforcing an unpopular savings measure, are carried by the Operating Partner in contractualised responsibility, not recommended on slides to an executive who will have to carry them alone.

§ 02Perimeter

They intervene inside the company, not alongside. Operational office, presence in executive committees, access to field teams, signature on decisions within their mandate. This immersion changes the nature of the relationship with collaborators, they do not respond to an external consultant ; they report to an interim executive with the legitimacy to decide.

§ 03Exit

It is prepared from day one, with knowledge transfer conditions documented. The Operating Partner is not there to stay, they are there to transform and hand over. This temporality shapes their decisions: they can carry difficult arbitrations without long-term political exposure. The difference with a permanent hire reads equally clearly, they have an objective and an exit date.

02· Plate, four intervention contexts

Intervention contexts.

Four dominant patterns frame Operating Partner missions in our sector, project in crisis, company in stagnation, leadership transition, post-acquisition.

01Project
in crisis

Envelope project in crisis.

Site derailing, schedules tight, liquidated damages, subcontractors in litigation, owner threatens termination. GC or facade contractor without internal capacity.

The in-place project director is overwhelmed, the technical director is on other dossiers, the executive cannot descend to the operational level. Operating Partner on project with authority to renegotiate, reset teams, arbitrate technical and contractual decisions. Explicit mandate from owner-manager or board, written into mission letter that defines the delegated (technical arbitration, contractual negotiation with the owner, subcontractor renegotiation, project team HR) and the reserved EXCO (financial commitment above threshold, external communication, strategic decisions).

02Company in
stagnation

Specialist company in stagnation or difficulty.

Facade contractor EUR 5–80 M no longer growing, gradual margin loss over 24-36 months, processes obsolete, technician executive overwhelmed.

The executive built the company on their trade expertise. They need a business complement who understands their trade from the inside, not an advisor who will produce a generic report, an operator who will take on the missing business function (sales leadership, industrial leadership, deputy general management) during the transformation period, with documented handover.

03Leadership
transition

Leadership transition.

Mutation, retirement, personal crisis, disposal, succession not ready, external recruitment = 6-12 months, the company cannot afford the interregnum.

The interim Operating Partner maintains momentum during the transition, prepares the handover (internal successor coaching, external recruitment support), stabilises teams and clients alerted by the departure, transmits cleanly to the successor once in post.

04Post-
acquisition

Acquisition or post-acquisition.

Investor (PE, family office, build-up industrial) acquires an envelope company, integration and optimisation carried by Operating Partner on behalf of the acquirer.

Frequent in build-up schemes where the acquirer does not yet have internal capacity to integrate each target. Also deployed when the target was underperforming before acquisition (distressed thesis) and post-acquisition value creation runs through a strong operational intervention over the first 12-24 months.

03· Plate, three phases · prepared exit

What we deliver.

The mission structures around three phases, diagnostic, intervention, stabilisation and handover. Each mission is framed by its own perimeter and objectives.

§ TLDR · 01Diagnostic, not slow audit.
§ TLDR · 02Decides, not recommends.
§ TLDR · 03Hands over, not stays.
§ TLDR · 04Exits, not indispensable.
Phase 1 · Diagnostic

Situation audit + prioritised action plan.

Mandator validation
Phase 2 · Intervention

Operational command-taking on agreed perimeter.

Real-time decisions
Phase 3 · Stabilisation & handover

Practice documentation · team training · exit.

Continuity without us

§ 01Diagnostic

Audit of the situation: ongoing contracts, financial flows, human resources, operational processes, client and supplier relationships. Identification of critical points, quick wins, urgent decisions. Deliverable: documented diagnostic with prioritised, costed, scheduled action plan, validated by the mandator (owner-manager, board, fund).

§ 02Intervention

Operational command-taking on the agreed perimeter. Per situation: contractual renegotiation owner/subcontractors, project team restructuring, procurement and logistics optimisation, commercial priority reset, internal process reorganisation, pilot indicator implementation, technical and legal dispute resolution, urgent digital or industrial transformation piloting. Decisions are taken in real time, not in committee.

§ 03Stabilisation and handover

Documentation of new practices installed. Training of teams that take over. Knowledge transfer to in-place executive, recruited successor, or new post-acquisition management. End-of-mission report. Documented exit with continuity conditions without us.

Note · what is NOT included

Permanent presence beyond the agreed perimeter · HR management beyond the mission (structural recruitments, long-term career plans) · responsibility for decisions taken after exit · recurring administrative reporting post-mission · generalist advisory outside the envelope perimeter.

04· Plate, four mandator profiles

For whom.

Four profiles structure our mandators, from the direct owner-manager to the GC/TC on a project in crisis.

01Owner-managers
beyond them

Owner-managers confronting a situation beyond them.

Project in crisis, structural transformation, unprepared succession, will assume operational responsibility without threatening their position.

Founders, heirs, owner-managers of specialist envelope companies. They seek an interim executive who will speak their language, that of the trade, not that of consulting, and who will assume operational responsibility without threatening their own position in the company.

02Funds
post-acquisition

Investment funds post-acquisition.

PE, sector construction funds, build-up funds, OP is the executive implementing the investment thesis, not an external advisor.

Mandate structured through the board with regular GP reporting. Investment thesis assumes strong operational intervention over the first 12-24 months.

GC/TC on an envelope project in crisis.

Mega-project where the envelope package derails, project OP takes leadership on behalf of GC with authority to renegotiate, arbitrate, manage owner claims.

Project leadership of a GC/TC on a mega-project where the envelope package derails to threaten overall project margin. Project Operating Partner with contractualised authority to renegotiate facade subcontractors, arbitrate technically, manage owner claims.

05· Plate, fixed fee + success fee

Pricing model.

Fixed fee + success fee on value created per mission typology. Capacity limited by structural discipline, not by commercial strategy.

∅ · Capacity limited by structural discipline

We limit the number of simultaneous Operating Partner missions to preserve actual operational engagement. The nature of this service demands substantial presence, quality cannot be maintained by multiplying missions. This discipline is structural, not commercial.

06· Plate, the DNA and three facets

What sets us apart.

The cardinal element is industrial experience lived from the inside. Three operational facets attach to it.

§ Pivot equation
Four contexts are made possible by seventeen years in the trade, the OP decides in real time because they have seen the sequence play out from the inside.
OUR ANCHORING

Seventeen years in the envelope trade.

Seventeen years in the envelope industry, including several years in pre-construction with a Tier-1 international contractor in glass envelope works. We come from the Tier-1 industrial envelope trade. We know the cost structures (where margin is made on a unitised curtain wall, where it is lost on a foreign site, how a system supplier protects its ratios), the commercial dynamics, the ecosystems, the pitfalls of envelope companies, from the inside. This knowledge saves 6 to 12 weeks of learning phase on an operational mandate.

01 / 03Combined competence

Combined tech + business.

Indissociable dimensions on facade company or envelope project in crisis, few profiles can arbitrate both.

A financial CRO will not settle a facade claim dispute on an out-of-spec tolerance point. A technical director will not renegotiate a banking line. The combination is the condition for operational effectiveness.

Facade techBusinessArbitration
02 / 03Trusted third party

Trusted third party posture.

No affiliation with client suppliers or competitors, legitimate arbitration even on considered suppliers.

This neutrality is a structural condition of our practice, not a sales argument. Documented contractually.

∅ affiliationLegitimate arbitration
03 / 03Documented exit

Documented exit.

We do not seek to make ourselves indispensable, we deliver, hand over, leave.

Continuity must remain possible without us, this is the proof the mission was done correctly. Any process or indicator installation is accompanied by its documentation.

07· Plate, articulation BE + EX + ME

Articulation with other offerings.

The Operating Partner articulates with several other atelier services according to the nature of the situation.

08· Plate, structural discipline

Absolute confidentiality.

Operating Partner missions are by nature sensitive. Internal teams, clients, partners, creditors and competitors must not discover before the action plan is structured.

∅ · Structural discretion engagement

Systematic NDA from the first exchange, before detailed description. Dossier isolation in separate restricted-access environments. No public reference to the mandate without explicit written agreement, not on website, not in collaterals, not in professional networks.

§ 01Strict non-conflict rule

We do not take two opposing mandates on the same project or the same company, including after a mission ends, during a contractualised cooling-off period.

§ 02Cross-mission isolation

Our Envelope Engineering missions on a project do not cross our Business Engineering missions on a company competing on that project. Teams are separated, and declaration to the client is preliminary to kick-off.

08bis· Plate, extended practice notes

The operating partner construction in long-form.

Three additional dimensions of the operating partner construction practice that recur across mandates and that prospective clients should understand before engaging.

§ 01Why the operating partner construction posture is rare

The operating partner construction role demands a rare combination of skills : technical mastery of the envelope lot (curtain wall, structural glazing, double skin facades, BIPV, anti-blast, anti-intrusion), contractual command across FIDIC, SIA, and CCAG frameworks, and the capacity to arbitrate under contradictory pressure between the owner, the design team, the general contractor and the supply chain. Most consulting firms cover one of these three axes ; very few cover all three simultaneously. Our practice is built on this triple mastery, and that combination is what makes the operating partner posture defensible against all parties on a contested project.

§ 02Engagement intensity and capacity discipline

An operating partner construction mandate is not a side activity, it requires substantial presence (3 to 5 days per week on the contracted scope), constant arbitration, and full engagement with the company's leadership team. We deliberately limit the number of simultaneous Operating Partner mandates to preserve the quality of execution. This capacity discipline is structural, not commercial : an OP mandate that becomes a part-time commitment loses the operational authority that makes it useful. Each mandate runs typically 12 to 24 months, with a defined exit date and a transmission protocol agreed at kick-off.

§ 03Discipline anti-conflict during the mandate

Holding an operating partner construction mandate over 12 to 24 months requires constant anti-conflict discipline. Any change in the project ecosystem (new general contractor partner, change of facade subcontractor, arrival of a new investor) triggers an internal conflict review with the client. Any incoming solicitation from another party in the project (a facade contractor seeking parallel mandate, a manufacturer offering partnership) is documented and declined. This passive discipline, which essentially amounts to refusing commercial opportunities while the OP mandate runs, is the cost of the posture. It is what makes the OP recevable as a legitimate intervenor through to the end of the mandate, including in the most contested moments where the team's neutrality is questioned.

§ 04Pricing and contractual structure

The pricing of an operating partner construction mandate combines a fixed monthly fee (covering committed time and operational engagement, non-refundable from the day of entry) and a success fee aligned with mission typology. On a project in crisis, the success fee is a percentage of saved value (penalties avoided plus margins recovered against a documented baseline). On a stagnating company, the success fee is a percentage of measured EBITDA improvement on a post-mission window (typically 12 to 24 months after exit). On a post-acquisition mandate, the success fee combines a fixed fee plus a percentage of the value created between entry and exit, calculated on the implied portfolio valuation. The precise levels are discussed mission by mission in transparency, depending on the situation and the agreed objectives.

§ 05Exit protocol and knowledge transfer

Every Operating Partner mandate ends with a structured exit protocol : documentation of installed processes, training of permanent teams who take over, transmission to the incoming director or to the existing leadership, written end-of-mission report covering achieved KPIs against entry baseline, residual risks identified, recommendations for the post-mission phase. The exit protocol is documented contractually at kick-off and reviewed monthly as the date approaches.
