Document digitization in construction: why is it worth it?

The construction industry handles a huge volume of documents: contracts, project designs, administrative decisions, powers of attorney, and as-built documentation. The traditional way of handling them means:

• the need for in-person meetings
• delays in signing
• the risk of lost documents
• logistical costs

A digital document workflow eliminates these problems, letting you:

• sign documents within minutes
• run processes fully online
• keep project documentation organized
• reduce formal errors

This is especially important for companies entering tenders, where response time and complete documentation are critical.

How does an online electronic signature work in construction?

An online electronic signature is the digital equivalent of a handwritten signature. Depending on the type of document, different forms can be used:

1. Qualified electronic signature (QES)

The highest level of security and full legal validity.

Use cases:

• construction contracts
• tender documents
• powers of attorney

You can also use a one-time qualified signature – for instance, for an individual client who doesn’t have their own certificate:

2. Advanced electronic signature (AES)

For internal documents or less formal processes.

3. Simple electronic signature (SMS / email)

A fast solution for everyday operations:

• document approvals
• confirmations of arrangements
• internal workflow

The construction process and e-signatures: what can you sign online?

Based on administrative and project processes, several key use cases stand out:

Design and formal documents

• architectural and construction design
• site development plan

Official documents

• decisions
• rulings
• official notices

Investor documents

• applications and submissions
• statements
• powers of attorney
• contracts with contractors

Tenders and B2B collaboration

For construction companies participating in tenders, online electronic signatures are a major convenience.

Benefits:

• fast signing of bids and attachments
• no need to deliver documents in person
• compliance with formal requirements

In B2B collaboration (for example, with subcontractors):

• signing contracts online
• fast contract amendments
• smooth document exchange

Individual clients: fewer visits, more convenience

Not every construction company operates solely on a tender-based model. For individual clients, CertumSign makes it possible to:

• send a contract for signature online
• let the client sign it remotely
• shorten the project finalization process

Importantly, even if the company prefers an in-person meeting, the client can:

• review the document beforehand
• approve it electronically
• avoid an extra visit just to sign
