Construction, finance, technology. Geneva.
The expertise others outsource.
From the financial model to the handover report: one single point of contact. We price with commitment, we cross-check verifiable data, we hold the site through to delivery. Where others deliver a report, we deliver the outcome.
BOH
/bi.o.aʃ/, acronym
proper noun1. Building On Hedging
Building on risk coverage. Every construction and investment decision rests on analysis that anticipates what can go wrong.
2. By extension
The only firm that goes from DCF modelling to site supervision with the same team. “We don’t outsource what we know how to do.”
The profile
Four areas of expertise. One team.
The market has field operators, financiers, process consultants, and “digital transformation” vendors. Nobody does all four. We do.
Site
Construction & delivery
Civil engineers. SIA standards, LDTR, trade coordination. We know what happens when concrete is poured, because we ran the sites.
Capital
Investment & valuation
Due diligence, DCF models, hedonic analysis within a leading Swiss real estate firm. We speak the language of investors.
Process
Operational excellence
MAS EPFL Real Estate. Operational process structuring and optimisation: identify, propose, coordinate, control.
Data
Tools & technology
Our own analysis tools. Cross-referencing cadastral, energy, market and real cost data. No third-party dependency.
The problem
Your project spans three worlds that don’t talk to each other.
An investor wants returns. An architect wants a vision. A contractor wants progress payments. Three languages, three logics, zero integration. Projects derail in these gaps, not in individual competencies.
The DCF model says 12M. The site costs 15M.
The financier doesn’t understand the field. They model assumptions, not construction realities.
The PM manages. But doesn’t challenge costs.
The operator knows the site but doesn’t question the business model. They execute the programme, even when sub-optimal.
The consultant optimises. Then leaves.
The firm delivers a report and recommendations. Nobody to implement them on the ground. Knowledge leaves the organisation.
Our thesis
The problem is never purely technical, purely financial, or purely organisational. It is always at the intersection. And that’s precisely where specialised firms fail: in the seams between their domains.
In practice
What this changes for your project
We don’t sell time. We sell measurable results. Here’s what happens when a horizontal integrator replaces a chain of specialists.
You coordinate 5 stakeholders: architect, engineer, consultancy, contractor, property manager. Each protects their scope.
One point of contact who speaks all three languages. From financial feasibility to the last site detail.

The estimate arrives 6 weeks later. ±15-20% margin of error. “What if we change the programme?” = back to square one.
Estimate in 48-72h with commitment. Scenarios recalculated in real time because we master both the model AND field costs.

The technical DD says “good condition”. The first winter reveals 800 MJ/m² energy consumption and a 2M renovation obligation.
Systematic cross-referencing: building condition × energy performance × LDTR constraints × real renovation costs. No surprises.

The consultant delivers an 80-page PDF. Relevant recommendations. Nobody to implement them. The PDF gathers dust.
We write the diagnosis AND manage the execution. Recommendations are implemented because it’s the same team on the ground.

Project know-how leaves with the consultants. Next project = repeat, new stakeholders, same mistakes.
Structured, transferable documentation. Knowledge stays in your organisation. Next decision = faster, better informed.

Traditional approach
With BOH
Our method
Every recommendation
has a verifiable source.
Most consulting firms rely on their experience. We systematically cross-reference official sources (federal, cantonal, and proprietary) to produce analyses you can audit line by line.
The result: investment decisions based on facts, not intuition. And a contractual commitment on our estimates.
Analysis layers
Structured report + costed scenarios. Every data point traced to its official source.
Services
What we do. No jargon.
Every service exists because we’ve seen the problem from the inside: site side, investor side, process side. Not from a PowerPoint.
Integrated due diligence
Technical × financial × energy
Not three separate reports. A single diagnosis crossing building condition, yield model, and energy performance. With LDTR compliance costs quantified, not estimated.
Owner’s representative
From feasibility to handover
We draft the programme, analyse tenders, negotiate with contractors, and supervise the site. Same contact from the financial model to the acceptance report.
Bid strategy
Public tenders & Design-Build
Winning a public tender is decided before any drawing: AIMP eligibility, assembling the consultant team, reading the criteria that truly carry weight. We build the bid where the jury actually scores, regulatory due diligence included (LDTR, senior-housing and energy standards).
Committed estimate
48-72h, firm commitment
No more ±15-20%. We cost your project with a contractual commitment (excl. asbestos/contamination). Possible because we know real costs, not market averages.
Renovation strategy
LDTR × CECB × subsidies
In Geneva, renovating without mastering LDTR is flying blind. We optimise the programme to maximise subsidies while respecting rent-control constraints.
DCF valuation
Geo-contextualised, not generic
Our models integrate real, verifiable data, not national averages. Every parameter is contextualised locally, because a building in Carouge isn’t worth the same as one in Eaux-Vives.
Construction management
Operational coordination
Site supervision by engineers who have run construction sites, not discovered them. Defect resolution, handover, warranties: we hold contractors to the last detail.
Frequently asked questions
How are you different from an architecture or engineering firm?+
We’re neither. We’re the owner’s representative who integrates the financial, technical, and operational dimensions into a single management. The architect designs, the engineer calculates. We make sure the project stands up, both economically and physically.
When in the project should we contact you?+
As early as possible. Before acquisition for due diligence, from feasibility for owner’s rep, or mid-construction if things go off track. The earlier we intervene, the more overruns we prevent, but we also know how to take over a project mid-course.
How much do your services cost?+
Fees depend on the mandate type. Due diligence: flat fee based on property size. Owner’s rep or construction management: percentage of works cost, depending on the nature and scale of the mandate. One-off estimate: fixed fee. We give you a precise figure after a 30-minute initial call.
What is technical due diligence and why is it essential?+
It’s the complete audit of a property before acquisition: building condition, energy performance, regulatory compliance, hidden costs. In Geneva, with LDTR, asbestos, and energy obligations, buying without due diligence is playing roulette.
Do you work outside Geneva?+
Yes. Geneva, Vaud, Valais, and Fribourg. We know the cantonal specifics (LDTR in Geneva, LATC in Vaud) and adapt our analyses to local context.
One project. One conversation.
No 15-field form. Call or write. We’ll tell you in 30 minutes whether we can help, and how.
