E-Signatures for Construction
E-signatures for construction. Subcontractor agreements, change orders, and safety waivers signed remotely.
The challenge
Construction companies manage subcontractor agreements, change orders, safety waivers, and lien releases across multiple job sites. Paper signatures on-site are impractical.
Common documents
- Subcontractor agreements
- Change orders
- Safety waivers
- Lien releases
- Material supply agreements
- Project completion certificates

E-signatures are valid for construction contracts under ESIGN. The audit trail provides evidence of agreement on change orders.
Industry deep-dive
Construction is uniquely challenging for document signing — work happens across multiple job sites, subcontractors are rarely in an office, and change orders need signatures before work can proceed. Paper-based processes mean delays measured in days, and in construction, time is money.
Key construction use cases:
1. Subcontractor agreements — Before any subcontractor starts work, the GC needs a signed agreement covering scope, rates, insurance requirements, and liability. With an API, generate and send these from your project management system. 2. Change orders — When scope changes on-site, change orders need signatures from the project owner, GC, and affected subs. E-signatures let all parties sign from the job site on their phones. 3. Safety waivers — Workers sign safety acknowledgements before entering a job site. Digital signatures create a verifiable record of safety briefing completion. 4. Lien releases — Partial and final lien releases can be signed electronically, accelerating payment flows. 5. Project completion — Punch list sign-offs, substantial completion certificates, and final payment authorisations.
The construction industry's adoption of e-signatures lags other sectors, but the ROI is significant: a typical commercial project involves hundreds of documents requiring signatures from owners, architects, general contractors, and subcontractors.
Frequently asked questions
Can construction contracts be signed electronically?
Yes. Subcontractor agreements, change orders, safety waivers, and lien releases are all valid with electronic signatures under ESIGN. E-signatures are particularly valuable for construction because parties are spread across multiple job sites.
Are change orders valid with e-signatures?
Yes. Change orders are standard commercial documents that are fully valid with electronic signatures. The SHA-256 audit trail provides tamper-proof evidence of agreed scope changes, timestamps, and signer identities.
Can workers sign safety waivers on their phones?
Yes. Workers can sign safety acknowledgements on any device with a web browser. Signbee sends a signing link via email — no app download needed. The signed certificate provides a verifiable record of safety briefing completion.
