CSBM GmbH — Site Management & Construction Management

Complex construction projects need more than planning. They need leadership.

Quality, cost and schedule are not a list of priorities. They are a balance. We maintain it – on site, every day, through to handover.

Our vision

Back to Basics.

Taking construction back to its core: clear decisions, solid craftsmanship, sound knowledge, responsibility and leadership that goes without saying.

CSBM GmbH has been operating since September 2025. The joint venture of Friedrich Schenner and Gavin Cooper brings more than 70 years of experience in the construction industry – in Switzerland and abroad.

We are experienced planners and construction project managers. We know what counts: durable, functional, high-quality buildings. Construction expertise is often neglected in the industry – yet it decides the success of every project. Without the right hands, the right expertise and professional support, delays, damage and unnecessary costs follow.

That is exactly why CSBM exists. We focus on execution – the phase that decides whether a design becomes a building that lasts.

We make it happen.

In a construction project, there are no priorities

Quality, cost and schedule must be in balance.

All three matter equally. There is no trade-off to make – it only becomes necessary when someone looks too late.

01

Quality

Experience in detailing delivers quality. Not inspection at the end, but knowledge at the start.

02

Schedule

Experience in execution secures the schedule. If you know the processes, you don't lose weeks at the interfaces.

03

Cost

Knowledge saves money. The most expensive decisions are the ones made too late – or not at all.

“You are only as good as your last project.”

Services

Six fields. One responsibility.

From full turnkey responsibility to targeted consulting – we step in where we make the biggest difference.

01Key in Hand

Turnkey projects

We take responsibility for the entire project delivery – from the first idea to turnkey handover. One point of contact, one responsibility, one result.

  • Complete project delivery from a single source
  • Coordination of the works and specialist site supervision
  • Quality assurance across all trades
  • Schedule and cost control through to handover
02We have the Knowledge

On-site construction management

We make sure the construction work meets every requirement and is carried out properly – every day, on site, backed by the expertise it takes.

  • Overall site coordination
  • Quality control in line with SIA standards
  • Schedule monitoring and sequencing
  • Contractor coordination and acceptance inspections
03Back on track

Project recovery

When a project loses its balance, it does not need a blame game. It needs structure. We analyse the situation soberly, reorganise and bring schedule and costs back under control.

  • Analysis of the current situation, without sugar-coating
  • Reorganisation of construction sequences
  • Restoring schedule and cost control
  • Transparent reporting to the client
04Clear and to the point

Project management

Structured project leadership with clear decision paths. We hold the interfaces between client, planners and contractors together – before they become a problem.

  • Structured project leadership
  • Interface management: client – planners – contractors
  • Risk analysis and problem solving
  • A basis for decisions, not just status reports
05Your interests, our job

Client representation

We represent the client where quality, cost and schedule are decided every day – with the experience it takes to ask the right questions.

  • Safeguarding the client's interests
  • Cost and schedule monitoring
  • Quality control of the works
  • Independent assessment of change orders
