Your all-trades
contractor in Geneva
Building expertise
Full technical coordination since 1981
When a site involves several trades, the main source of delays and cost overruns is not technical: it is the lack of coordination. As a general contractor in Geneva, Class Orga directly manages all building trades under a single responsibility. A single project manager, a single contract, a single schedule.
Our all-trades capability covers the entire chain:
- Structural work: masonry, foundations, slabs, underpinning
- Electrical and lighting: boards, cabling, LED, home automation, OIBT compliance
- Heating and ventilation: heat pumps, dual-flow ventilation, control
- Plumbing: sanitary networks, hot water, drainage
- Plastering, painting, plasterwork: drywall, renders, finishes
- Fire protection insulation: penetrations, joints, AEAI-certified doors
- MCR automation: BMS, supervision, energy monitoring
- Floor coverings, suspended ceilings, waterproofing: floors, acoustic ceilings, roofs
- Joinery and fitting: custom furniture, staircases, claddings
- IT networks: copper, fibre, Wi-Fi, IP video surveillance
Flat, offices, building or commercial premises: the principle is the same. Each trade works at the optimal time, quality checks are carried out at every stage and SIA standards are respected. This rigour, applied for over 40 years, is what guarantees reliable works and deadlines met.

Our approach in
all-trades works
At Class Orga, our team dedicated to office fit-out stands out for its approach. It is centred on careful listening to your needs and in-depth reflection to design workspaces that reflect who you are. Every project is the result of close collaboration and considered thinking to guarantee a work environment aligned with your aspirations and objectives.
During the office fit-out design phase, we make it a point of honour to bring your vision to life. We begin by taking into account your expectations regarding the atmosphere you want for your future offices. Our team then carries out a careful selection of different materials, furniture and finishes. Our aim is to prepare a representative rendering of the completed works, letting you visualise the final result.
So you can get a concrete preview of your future offices, we produce 2D plans and 3D visuals to give you a complete architectural concept. We account for every constraint and specific feature of your premises to provide a bespoke solution. We integrate every selected element into the plan so you can better picture yourself in your future workspace.
Drawing on extensive experience running construction sites in Geneva, the Class Orga team stands out for its dedicated site supervision right through to project handover. We make a point of supporting our clients at every stage, delivering flawless execution and complete satisfaction throughout the office fit-out process.

We answer all your questions
Class Orga uses an integrated project-management methodology with a phased, detailed schedule. Each trade intervenes in an optimised technical sequence: structural works, then technical services (electricity, plumbing, heating), followed by partitions and finishings. A single project manager prevents interface conflicts.
Class Orga holds every mandatory Swiss certification: OIBT electricians, SUISSETEC plumbing-heating specialists, masons with SIA training. Our professional insurance covers every trade. Every intervention complies with Geneva cantonal standards and current energy requirements.
The Class Orga approach optimises overall costs by eliminating multiple margins, coordination overheads and interface-defect rework. Our single quote covers every line item with no surprises. The savings on scheduling and management more than offset our technical coordination fees.
Our upfront diagnostic identifies 95% of the cross-trade technical constraints. For the remaining unknowns, Class Orga has multi-skilled teams and on-hand material stock to resolve any technical conflict immediately without halting the site. Adaptive solutions are built into the technical contingency.
Every Class Orga construction project is covered by the statutory Swiss warranties: a two-year warranty on equipment and a ten-year warranty on the structural integrity of the works. Class Orga adds its own satisfaction warranty with tailored post-handover support. Our all-risk site insurance fully covers your project for the entire duration of the works.
