What is DTAC documentation?
DTAC, or Technical Documentation for Construction Authorization, is the set of drawings, technical reports, and approvals required to obtain a construction permit.
Without this documentation, no construction work can legally begin. Its main purpose is to prove that the future building complies with urban planning regulations, safety standards, and technical requirements.
What construction permit documentation includes
A complete documentation package usually includes:
- Site plan and location plan
- Architectural drawings
- Structural design report
- Building installation projects
- Geotechnical study
- Topographic survey
- Utility approvals and permits
All these elements must be coordinated and prepared by authorized specialists. Even one missing document may lead to the rejection of the permit file.
Who prepares the documentation
DTAC documentation is usually prepared by a multidisciplinary team:
- Architect
- Structural engineer
- Building services engineer
- Geotechnical specialist
- Licensed surveyor
Dromcons provides all these integrated services, eliminating the need to coordinate multiple suppliers separately.
Common mistakes
- Missing geotechnical study
- Incomplete drawings
- Incorrect topographic data
- Inconsistencies between technical disciplines
- Submitting outdated documentation
These mistakes often lead to delays, rejected files, and additional project costs.
