Revision Documents for Civil Engineering: Avoid Costly Mistakes and Secure Your Projects!

The billion-dollar problem: The true costs of construction defects

Mistakes on the construction site are expensive and unfortunately not uncommon. In Germany, the costs caused by construction defects amounted to around 16.5 billion euros in 2021. This corresponds to a share of over 11% of the total industry revenue. For your company, this means: Every undocumented or poorly documented defect directly reduces your profit. In almost 40% of cases, the costs for rectifying the defects range from 5,000 to 50,000 euros. These figures show that professional defect management is not a luxury, but an economic necessity. A comprehensive photo documentation on the construction site is the first step towards security. Without proper recording and tracking, remediation costs can skyrocket and jeopardize the profitability of entire projects.

Avoid legal pitfalls under VOB/B and BGB

The legal framework for defect claims is strict. Whether under VOB/B or BGB, thorough documentation is your best insurance. According to § 13 VOB/B, as a client, you are entitled to subsequent performance but must give the contractor a reasonable deadline. The warranty period for buildings is generally 4 years under VOB/B, and even 5 years under BGB. A written defect complaint is crucial to interrupt the limitation period and secure your claims. Without legally secure proof of the defect, the time of reporting, and the set deadline, you often find yourself empty-handed in the event of a dispute. A professional defect management app provides the necessary process security and protects you from costly legal disputes.

Why WhatsApp and Excel are not enough for defect tracking

Many teams try to organize defect tracking using simple tools like WhatsApp or Excel. However, these methods have serious drawbacks that quickly lead to problems in everyday construction. Information gets lost in unstructured chats, and clean project-specific assignment is hardly possible. Ensuring thorough evidence on the construction site is not feasible this way. Here are the 4 biggest weaknesses of these makeshift solutions:

  • Lack of legal certainty: Chats and simple spreadsheets do not meet the requirements for legally secure documentation under VOB/B. Timestamps and the exact sequence are difficult to prove.
  • High manual effort: Photos, voice notes, and texts must be manually transferred from the smartphone to the office, sorted, and assigned. This costs up to 5 hours per week per employee.
  • No centralized overview: There is no central location where all defects and their current status (open, in progress, completed) are visible to all parties involved.
  • Data protection (GDPR): Using personal WhatsApp accounts for business communication is highly problematic from a data protection perspective and can lead to significant penalties.

These inefficient processes inevitably lead to misunderstandings and delays.

The solution: A centralized defect tracking app for the construction site

A specialized defect tracking app for construction digitizes the entire process from recording to acceptance. It creates a central platform where all information converges. The key advantage lies in the structured and seamless working method. Defects are recorded directly on-site with a smartphone and are immediately available in the office. Digital documentation reduces administrative effort by up to 70%. A good software provides the following core functions:

  1. Mobile recording: Document defects with photos, notes, voice memos, and precise plan localization directly on the construction site.
  2. Automated reports: Daily construction reports and defect protocols are generated at the push of a button as PDFs, including all photos and comments.
  3. Central task management: Each defect is assigned a responsible person and a deadline, the compliance of which is automatically monitored.
  4. Legally secure documentation: All entries receive an immutable timestamp and are archived chronologically and comprehensively.

This makes the task tracking on the construction site transparent and efficient.
