Site supervision across all trades
We are your reliable partner on site — because professional supervision decides whether the quality that was designed is the quality that gets built.
At a glance
Quality management at 38 Grad Gebäudetechnik covers specialist site supervision of every technical trade: installation checks, coordination of the installing contractors, programme and cost control, verification of contractor invoices, support through commissioning, and handover and defects management under SIA 118.
- On site: regular inspections with documented control points
- Commercially: target-actual comparison against award sums, factual assessment of variations
- At completion: balancing, measurement records, handover under SIA 118, warranty tracking
Quality is not created in the drawing — it is created on site
Specialist site supervision plays a decisive role in keeping construction running smoothly and in assuring quality.
From design through delivery it secures the highest standards and on-time completion through technical expertise and effective coordination of all trades. Our experienced team takes on site supervision for every discipline, on the ground.
Quality comes first for us. We monitor the works continuously and carry out regular quality checks — documented, so that in the event of a dispute it remains traceable what was found when, and what was done about it.
We place particular weight on commissioning. Where balancing, hydraulic adjustment and control parameterisation are cut short, the consequences appear only in the first heating season — as comfort complaints and excess consumption. That is exactly what we prevent.
What we actually deliver
Installation checks
Verification against drawings, specification and standards — including elements that will be concealed, before they are closed up.
Programme and cost control
Target-actual comparison per phase, tracking of variation claims, verification of contractor invoices.
Coordination of trades
Alignment of installers with each other and with construction management, architecture and the main contractor — on site, not through email chains.
Commissioning and balancing
Functional testing, air volume balancing, hydraulic adjustment, control parameterisation and measurement records.
Handover under SIA 118
Structured handover with minutes, defects schedule, deadline tracking and complete as-built documentation.
Aftercare in the first year
Support through the first heating season, readjustment of controls and verification of the performance figures achieved.
Why choose us?
Experience and technical depth
We spot installation errors while they are still cheap to correct — and know which details actually matter.
Commitment and reliability
Documented inspections, clear minutes, dependable dates. You always know where the project stands.
Measured by handover
Our benchmark is a handover without material defects — and a system that simply works through the first winter.
Frequently asked questions about quality management
What does specialist site supervision cover?
It covers on-site supervision of the technical trades: verifying compliance with drawings and specification, coordinating installers with each other and with the construction programme, controlling time and cost, verifying contractor invoices, overseeing commissioning and handover, and running defects management.
Which standard governs handover?
For construction works, SIA 118 «General conditions for construction work» applies. It governs acceptance procedures, notification periods, warranty periods and the treatment of defects. A structured, minuted handover is what makes warranty claims enforceable later.
What belongs to a proper commissioning?
Functional testing of all systems, balancing of air volumes, hydraulic adjustment, parameterisation of the controls, measurement records, training of operating staff and complete as-built documentation. Where this step is cut short, the consequences surface in the first heating season — usually as comfort complaints and excess consumption.
How do you keep programme and cost under control?
Through continuous target-actual comparison per construction phase: cost control against the award sums, factual assessment of variation claims and documented decisions. Clients receive periodic reports that state the position without technical jargon.
