Construction Supervision and Inspection Trust is good, but verification is better

Construction Supervision/Inspection Surveys

Trust is good, but verification is better

Inspection surveys are an essential part of assessing whether the contractually agreed-upon services have been performed properly and in full. They serve not only to verify compliance with specifications and standards, but also to ensure continuous quality monitoring of the building materials used and the individual layers.

Furthermore, inspection tests provide important evidence of proper contract fulfillment. Last but not least, they make a decisive contribution to the long-term functionality, safety, and value retention - and thus the sustainability - of your sports facility. Careful inspection during the construction phase helps identify defects early on and avoid costly corrective work.

We provide expert support and guidance as you work toward creating your ideal sports facility. Trust forms the foundation of a successful partnership, and inspections are the essential tool for ensuring quality. Through professional construction supervision and targeted inspections, we can ensure that your construction project is completed on schedule, cost-effectively, and successfully.

Thanks to our many years of experience, we are at your side throughout the entire construction phase with technical expertise, advice, and practical support. Let us guide and oversee your construction project - whether through third-party supervision or in-house monitoring. This provides you with a high degree of security and transparency, and you can be confident that your project will meet your desired requirements.

With regard to the legal significance of the inspection, reference is made to the commentary on VOB Part C - Landscaping Work: “The careful and thorough performance of inspections is an explicit obligation of the Client as part of its construction supervision. Only through these inspection checks can a proper assessment of the contractual quality of the contractor’s work be made, thereby creating the prerequisite for a proper acceptance. If existing defects are not identified prior to or at the time of acceptance due to omitted or incomplete inspection checks, the Client bears the full burden of proof for defects that become apparent after acceptance.”
