Construction and acceptance supervision with greentech<\/strong><\/p>\n

With our construction supervision, we support you during the construction phase of your PV, BESS, or substation project, ensuring through recurring inspections that construction is carried out according to plans and standards, and in compliance with design documents.<\/p>\n

This allows potential defects to be identified early, addressed specifically, and reduces risks of delays, rework, and additional costs until commissioning.<\/p>\n

For acceptance, we accompany you with visual inspections of mechanical and electrical main components, verify the rectification of known issues, and conduct an \"as-built\" documentation check \u2013 including a report and presentation of the results.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n

When<\/span> is construction and acceptance supervision beneficial?<\/h2>\n<\/div><\/div>\n<\/div>\n\n
\n

If you want to independently verify execution quality<\/h3>

Especially as a project owner or future operator, you want to know early on whether the execution matches the design documents and if the quality \"in the field\" is satisfactory. Our spot on-site inspections during construction supervision provide you with an independent, verifiable assessment \u2013 without interrupting the construction process. <\/p>\n<\/div><\/div>\n\n

If you want to identify and address deviations early<\/h3>

Many defects can be remedied more easily and cost-effectively in early construction phases than shortly before acceptance. Recurring appointments during key phases reveal deviations before they become integrated into other trades or lead to delays and additional costs. <\/p>\n<\/div><\/div>\n\n

If you want to set inspection priorities along the construction schedule<\/h3>

Not every construction site requires the same depth of inspection everywhere \u2013 critical construction sections and interfaces are decisive. We coordinate the focus points with you before each appointment based on the construction schedule, so that inspections are carried out where the risk to quality, acceptance security, and later operational management is particularly high. <\/p>\n<\/div><\/div>\n\n

When multiple parties are involved (e.g., Owner, EPC, Advisor)<\/h3>

In projects with multiple parties involved, technical questions often arise at handovers, responsibility boundaries, or interpretations of planning statuses. A structured, neutral overview helps to objectify discussions, clearly identify open points, and efficiently coordinate their resolution \u2013 especially before acceptance. <\/p>\n<\/div><\/div>\n\n

If you want to systematically track identified defects<\/h3>

A punch list is an effective tool for cleanly documenting and prioritizing findings or defects, and for maintaining transparency regarding responsibilities and statuses. As part of construction supervision, we can support defect tracking upon request, ensuring that known issues are not lost and can be verifiably checked for acceptance. <\/p>\n

 <\/p>\n<\/div><\/div>\n\n

If thorough acceptance preparation is a priority<\/h3>

For acceptance, we accompany you with spot visual inspections of mechanical and electrical main components and check whether known defects from previous appointments have been rectified. This creates a reliable basis for the acceptance decision \u2013 technically sound, documented, and with a clear status of open items. <\/p>\n<\/div><\/div>\n\n

If documentation needs to be \"ready for acceptance\"<\/h3>

Incomplete or inconsistent documentation is a common reason for delays in acceptance and handover to operation. With the documentation check based on a checklist \/ as-built, we support you in systematically reviewing project documentation and identifying missing or implausible content early. <\/p>\n<\/div><\/div>\n\n

If you need a better overview on large or complex construction sites<\/h3>

Depending on the project setup, supplementary construction site documentation can help to make progress more comprehensible and substantiate findings. For this purpose, we also use drone technology if necessary \u2013 e.g., to capture the construction site from different perspectives and better assess construction progress over time (project and approval dependent). <\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n
