What Is Site Instruction?
A site instruction or SI is a formal written communication in construction or project management that provides specific instructions, changes, or additional requirements related to a construction project.
It outlines changes to the project scope, design or schedule, and serves as a way of documenting and communicating these modifications to relevant parties such as contractors, subcontractors and project managers.
Site instructions are used to maintain clear communication and ensure that everyone involved in the project is aware of any changes or updates.
I also recommend you to read my article on Non Conformity Report (NCR).

Construction Site Instruction Vs Change Order
I have described the difference between Construction Site Instruction Vs Change Order.
| Aspect | Site Instruction (SI) | Change Order |
|---|---|---|
| Nature | Directives issued to construction personnel for alterations or adjustments within an ongoing project. | Formal requests for substantial modifications to the original project scope prior to implementation. |
| Occurrence | Implemented during the course of construction to rectify minor issues or accommodate minor modifications. | Solicited at the project planning stage for significant deviations from the initially approved project plan. |
| Originator | Typically initiated by the project’s supervisory authority. | Generally initiated by the client, architect, or main contractor. |
| Promptness | Expedited implementation due to the immediate context. | Involves deliberation, consultation, and detailed evaluation. |
| Financial Impact | Normally entails negligible financial adjustments. | Often leads to considerable financial implications. |
| Temporal Considerations | Generally conducive to swift execution. | Requires thorough contemplation, potentially leading to project delays. |
| Formal Documentation | Commonly verbal or communicated through concise notes. | Requires formal written documentation to ensure clear understanding and consensus. |
| Illustrative Examples | “Adjust the light fixture placement.” | “Requesting the addition of an annex building to the architectural layout.” |
Advantages Of Construction Site Instruction
1. Clear instructions for everyone
Construction Site Instructions (SI) provide clear, easy-to-understand instructions. This helps everyone know exactly what to do to avoid confusion.
2. Make changes as needed
SI allows site changes to be made in the event of unexpected issues. This helps construction workers adapt and solve problems quickly.
3. Get things done quickly
SI helps workers and teams communicate better, allowing tasks to be completed faster. It is important to complete the project on time.
4. Make things right
SI ensures that construction works follow the correct regulations and use the appropriate materials. This means that the end result will be strong and of good quality.
5. Keep everyone safe
SI contains important safety rules for worker safety. This helps prevent accidents and keeps everyone safe on the job.
6. Quick problem solving
If there is any problem on the construction site, SI provides a solution to fix it. This helps the workflow to run smoothly without any major delays.
7. Saving Money
With SI, problems can be fixed quickly, eliminating the need for costly changes later. This helps the project stay within budget.
8. Work well together
SI helps different teams on a construction site work better together. It’s as if everyone knows their part in a big mystery.
9. Write down important things
SI is like writing down important decisions. This may come in handy later if there are questions about consent.
10. Communication and exchange of information
SI helps the people in charge of the project talk to each other. This way, everyone knows what’s going on and can share important updates.
