A daily site report is one of the most important documents a site supervisor or foreman produces on any construction project. It is your written record of everything that happened on site that day .. the work done, the workers present, the materials used, the weather, and any issues that came up.
Most supervisors write them quickly at the end of a long day and miss key information. That creates problems later .. during disputes, audits, contractor valuations, or when something goes wrong and no one can remember exactly what happened.
This guide breaks down what a proper daily site report must contain, how to structure it, and what separates a useful report from one that causes more problems than it solves.
Quick Answer: A daily site report must include the date, weather conditions, workers on site (with trades and numbers), work activities completed, materials received, equipment on site, safety observations, visitor log, and any issues or delays with their causes. It must be signed and dated by the responsible supervisor.
Why Daily Site Reports Matter More Than Most Supervisors Realise
Many site supervisors treat the daily report as an administrative task .. something to fill in quickly before heading home. That is the wrong way to think about it.
The daily site report is a legal document. In the event of a dispute, a delay claim, a contractor valuation, or an insurance matter, your daily reports become primary evidence. Courts, arbitrators, and contract administrators all rely on site records to establish what actually happened and when.
In Kenya’s construction environment, contractors working under FIDIC contracts, NEC contracts, or standard JBC conditions of contract are required to maintain daily records. If a contractor claims for additional time or money, the first thing a contract administrator will ask for is the site diary.
A well-kept daily report protects you, your employer, and your client.
What a Daily Site Report Must Always Contain
The exact format can vary by company or project, but every daily site report needs these core elements:
1. Date, Day, and Weather
Record the date, day of the week, and weather conditions at different times .. morning, midday, and afternoon. Weather affects productivity, concrete pouring, earthworks, and safety. If bad weather caused a delay, your report needs to prove it.
2. Labour on Site
List every trade present, the number of workers per trade, and their supervisor. For example:
- Masons: 8
- Steel fixers: 4
- Carpenters (formwork): 6
- Labourers: 12
- Site foreman: 1
Include absenteeism if workers were expected but did not show up.
3. Work Activities Completed
Describe what was actually done .. not what was planned. Be specific. “Concreting of ground floor slab, grid lines A-D / 1-5, 45m³ poured” is useful. “Concreting done” is not.
4. Materials Received
Record every delivery: supplier, quantity, delivery note number, and where materials were offloaded. This directly supports your bill of quantities and contractor payment valuations.
5. Plant and Equipment on Site
List all equipment present and whether it was working or idle. If a concrete mixer broke down for three hours, that goes in the report.
6. Safety Observations
Note any safety inspections done, near misses, incidents, PPE compliance, and toolbox talks conducted. This is a requirement under OSHA 2007 in Kenya and equivalent legislation in other East African countries.
7. Visitors and Inspections
Record every visitor .. client representative, engineer, quantity surveyor, building inspector. Include what they inspected and any instructions given verbally on site.
8. Issues and Instructions
If there was a problem .. material shortage, design clash, delay, dispute between contractors .. it goes here. Include the cause and any action taken or decision made.
How to Write the Work Activities Section Properly
This is the section most supervisors write too vaguely. Here is the difference:
Weak: “Brickwork and roofing works done.”
Strong: “External block wall brickwork, first floor: completed grid lines 1-3 / A-B, 12 courses laid, 240 blocks used. Roof timber wall plates fixed in position on north and east elevations.”
The stronger version tells you exactly where the work was done, how much was done, and what materials were consumed. This matters for payment, progress tracking, and record-keeping if rework is ever disputed.
The rule is simple: write so that someone who was not on site that day can understand exactly what happened and where.
Common Mistakes That Undermine Your Site Reports
These are the errors that make reports useless when they are needed most:
- Writing it the next day from memory. Site reports should be written on site, in real time, or compiled at end of day before leaving site.
- Not recording delays. If a subcontractor caused a one-hour delay, that needs to be documented with the cause and time lost.
- Missing signatures. A report without a dated signature from the responsible supervisor has no legal standing.
- No reference to drawings or specifications. Reference the drawing number or spec clause where relevant. For example: “Slab poured as per structural drawing S-04, Rev B.”
- Only recording problems. Record progress too. When things go well, that is also part of the official record.
Digital vs Paper Site Reports
Most sites still use paper diaries. That is acceptable as long as reports are stored properly and not lost. However, digital systems are becoming standard on larger projects .. apps like Fieldwire, PlanGrid, and local WhatsApp-based reporting systems allow photos to be attached and timestamps to be automatic.
Honestly, the tool matters less than the discipline. A consistent, accurate paper diary kept daily is worth more than an inconsistent digital one.
If your company uses paper, number your pages, keep a duplicate copy, and file weekly. If digital, ensure reports are saved to a shared cloud folder the same day they are written.
Frequently Asked Questions
Q: How long should a daily site report be?
There is no fixed length. A productive day with multiple activities may produce a two-page report. A quiet day may be one page. What matters is that every key category is covered .. even if the answer is “nil” or “none.”
Q: Who is responsible for writing the daily site report?
On most contracts, the site supervisor or resident engineer is responsible. On large sites with multiple subcontractors, each subcontractor may maintain their own daily diary, and the main contractor’s supervisor keeps an overall project diary.
Q: Can a daily site report be used as evidence in a legal dispute?
Yes .. and this is exactly why accuracy matters. Under FIDIC and other standard contracts, contemporary site records including daily reports are admissible as evidence in arbitration and litigation. Gaps, inconsistencies, or vague entries weaken your position significantly.
The Bottom Line
A daily site report is not paperwork for its own sake. It is your professional record of what happened on site, and in the construction industry, records are everything. Develop the discipline of writing clear, specific, dated reports every single day .. and train your team to do the same. That habit protects the project, protects the client, and protects you.
