The Site Diary App Built for Construction Teams
Site supervisors spend 30-60 minutes each evening writing up what happened on site from memory. Sitemate builds the site diary as work happens, capturing photos, crew movements, weather, and progress throughout the day. The supervisor reviews, adds context, and approves before heading home.

Why Site Diary management Is Harder than It Should Be
End-of-day memory gaps
Supervisors try to remember weather conditions, crew numbers, work completed, and incidents from hours earlier. Critical details get missed or forgotten.
Rushed documentation
After a long day on site, diary writing is rushed and tired supervisors want to get home. Quality and consistency suffer.
Inconsistent record formats
Different supervisors document differently across projects, making it hard to find information or maintain audit-ready records.
Lost project history
Incomplete or inaccurate site diaries create gaps in project documentation that hurt contract claims and client handovers.
A Smarter Way to Manage Site Diary
Automatic diary drafting
AI compiles photos, voice notes, weather data, and crew check-ins into structured diary entries as work happens throughout the day.
Real-time activity capture
Weather and location data, crew attendance, materials delivered, and work progress are logged automatically through mobile forms.
Supervisor review and sign-off
Supervisors review the drafted diary, add context about decisions or issues, and approve the final record before leaving site.
Lost project history
Site diaries link directly to photos, inspection records, and incident reports from the same day, creating comprehensive project documentation.
How AI builds your site diary
AI Form Fill compiles all site activity captured during the day into structured diary entries. The supervisor reviews the drafted content, adds missing context, and signs off on the final record.
Capture site activity
Photos from site, voice notes describing work progress, crew check-ins, and materials delivery are captured through mobile forms. Weather and location data are logged automatically through the Weather Field and Location Field.
AI compiles diary entries
AI maps all captured inputs to the correct diary fields: date and weather, crew attendance, work activities by time and location, visitors, delays, instructions received, and materials delivered. Entries are structured chronologically.
Generate structured record
The system creates a complete daily record with all activities, decisions, and site conditions documented against the project timeline with supporting photos and data.
Supervisor review and approval
The supervisor or project manager reviews the drafted diary at day’s end, adds context about decisions made or issues encountered, and signs off before the record is finalised and logged against the project.

Understanding Site Diary Software
What is a site diary?
A site diary (also called daily diary, site log, or daily construction log) is the official daily record of all activities, conditions, and events on a construction or civil project. It documents weather conditions, crew attendance, work completed, materials delivered, visitors, delays, instructions received, and any incidents or safety issues. Site diaries are legal project documents required for contract compliance, progress claims, dispute resolution, and client handovers. They create the official project history and must be completed daily by the site supervisor or project manager.
What gets recorded in a site diary:
- Date, weather conditions, and site conditions
- Crew attendance, subcontractors, and visitor logs
- Work activities completed by location and trade
- Materials and equipment delivered or removed
- Delays, variations, and instructions received
- Safety incidents, near misses, and corrective actions
Why site diaries matter for project success
Accurate site diaries are essential for progress claims, contract variations, and dispute resolution. They provide the evidence needed to justify additional costs, demonstrate compliance with specifications, and support claims for time extensions. Poor diary records can cost contractors significant money in disputed claims and create compliance issues with clients and regulatory bodies.
How To Set Up a Digital Site Diary Using Sitemate
Step 1:
Step 2:
Deploy to project sites. Roll out diary templates to active projects with mobile app access for supervisors and foremen. Set up automatic weather capture and location services for each site.
Step 3:
Train supervisors on mobile capture. Show supervisors how to capture photos, voice notes, and activity updates throughout the day using the mobile app. Highlight real-time capture over end-of-day data entry.
Step 4:
Configure approval workflows. Set up diary review and approval processes with project managers. Define who can sign off on daily records and how completed diaries flow to clients or head office.
Step 5:

Frequently asked questions about Site Diary
Will AI capture everything that happened on site?
AI drafts the diary from data already captured on site through photos, voice notes, forms, and automatic sensors. The supervisor reviews the drafted content and adds anything missing before sign-off. You’re still in control of what gets recorded in the final diary.
How does the mobile app work for supervisors in the field?
Supervisors use the mobile app throughout the day to take photos, record voice notes, log crew attendance, and update work progress. The app works offline and syncs when connectivity returns. All data is automatically timestamped and located.
Can site diaries be tailored for different project types?
Yes, diary templates can be configured with specific fields for different project types – civil, commercial, residential, or infrastructure. You can add custom fields for focused activities, compliance requirements, or client specifications.
How do completed site diaries integrate with project reporting?
Approved site diaries automatically link to photos, inspection records, and incident reports from the same day. They flow into project dashboards, progress reports, and client portals without manual data entry or document handling.
What happens if supervisors forget to capture activity during the day?
Supervisors can add missing information during the evening review before approving the diary. The system shows what’s been captured automatically and highlights any gaps. Voice notes and photos can be added retroactively if needed.
Are digital site diaries legally acceptable for contract compliance?
Yes, digital site diaries with timestamps, photo evidence, and electronic signatures meet legal requirements for project documentation. They often provide stronger evidence than paper records due to automatic timestamping and audit trails.
How long does it take supervisors to review and approve daily records?
Most supervisors spend 5-10 minutes reviewing the AI-drafted diary and adding any missing context, compared to 30-60 minutes writing traditional site diaries from memory. The review process ensures accuracy while saving significant time.
