Building a house or buying a new flat from a developer (Bauträger)? We inspect the work at the stages when building parts are finished but still open: foundations, shell, airtightness, before the screed, before acceptance. After every visit you receive a report that separates findings from assessment – and for the acceptance (Abnahme) a snagging list that holds.
Acceptance of your flat and of the common parts is the moment when the burden of proof and the deadlines shift. We inspect beforehand, record defects with reservation and attend the appointment. Payments to a developer are due in instalments as construction progresses – a visit before an instalment shows whether the stage has really been reached.
You have a contract with specification and payment plan, but nobody who checks the work in your interest. We read the documents, come at the decisive stages and tell you what you can approve.
Roof, façade, bathroom, basement: existing buildings hold more surprises, and the junctions with existing parts decide whether everything stays tight. We check before it is covered up.
After every visit a report with construction stage, findings, assessment and recommendation, including photos of the parts that will soon be covered. A defect list with urgency, a completed acceptance protocol, pointers on the technical basis for releasing payments and a template for the notice of defects. Questions by phone between visits are included in the package.
We do not run the site and do not instruct the contractors – that stays with the site management and your contractual partner. We do not prevent defects; we make sure they are noticed earlier and documented. Legal consequences, withholding payments and deadlines are for your lawyer. Comprehensive site supervision as client's representative (HOAI work stage 8) is offered separately.
Fixed prices after a short call; the scope described is included. Travel within Berlin included, Brandenburg by distance. Measurements by specialist firms (airtightness, thermography) are charged separately and quoted beforehand.

The value of construction monitoring depends on timing: what lies under the screed cannot be seen once the screed is in. That is why we plan visits by construction stage and keep call-off windows free. Site supervision and expert reports on construction defects are part of our work – we know where it gets expensive later.

Accompanied by the client, as a rule yes; many construction contracts expressly provide for access. We recommend informing the contractor of the planned inspection dates before construction starts – it takes the edge off the visits and makes coordination easier.
Building parts are often finished and still open for only one or two days. In the package we therefore keep visits available within 48 hours of your call; single visits are booked by availability, usually within five working days. Tell us the expected construction schedule and we plan the windows in advance.
Site supervision (HOAI work stage 8) is the designer's ongoing construction management with site diary, scheduling and invoice checks. Construction quality inspection is an additional, sample-based check on your behalf. Comprehensive site supervision as the client's representative is offered separately by quote.
You receive the finding with photo, assessment and recommendation in the report. The defect has to be notified in writing to your contractual partner, not to the tradesperson on site; our notice-of-defects generator produces the German letter. Whether and how you may withhold payments is a question for your lawyer.
Especially then. With acceptance the burden of proof shifts, and known defects have to be reserved in the protocol. With a developer, your own unit and the common property are accepted separately; we attend both and tell you what belongs in which protocol.
