Please insert construction plan drawing of the project with assigned numbers to each elevation. (See point 3 of the reporting Rules)
-
BEFORE YOU START THIS REPORT, REFERENCE MUST BE MADE TO THE PROJECT ELEVATION LAYOUT SKETCH DETAILING THE EXACT LOCATION(S) INSPECTED.
Rules of WIR and Progress Reporting:
1. All reports need to be in for the dates that have been agreed on the Reporting Schedule. PM must contact HSEQ Department if there will be a delay.
2. The elevation inspected must be clearly identified using the Elevation Layout Sketch produced by the CM of the project, clearly identifying each elevation and floor. Ideally, there should be a separate Report for each elevation, however on smaller works, a single report for more than one elevation is acceptable.
3. Each report should include a description of the type of system / works undertaken.
4. Reports should also include quality issues not caused by CF, but which impact on our works.
5. Refer to recent Supplementary Quality Reports before starting.
6. We have issued standard Detail drawings reference numbers D01, D02, and so on. These need to be referred to throughout WIR and clearly show what is required. Only “Clarke” Drawings should be followed.
7. All reports must be up-loaded to Clarkes Server or emailed to HSEQ Dept before deadline.The next report that will follow must show how the errors were rectified. If improvement was not possible, e.g.: due to soft ground/lack of access, it needs to be described/explained. The answers column still needs to be highlighted red. However, if the error was rectified the section should be changed to green. The comment section is to be used for explanations of how and when error was rectified.
8. If project manager has found an error during the assessment, it must be noted and fixed before consecutive stages of works progresses, eg: CP board cannot start before Metsec sub frame is properly fixed. Quality Control Manager cannot accept the next WIR report until everything is fixed and up to date on the previous report. This is to make sure that all errors are corrected, and there are no error omissions.
9. Reports need to be genuine and relevant.
10. It is important that reports always have any delay events recorded.
11. All completed reports must be sent to head office, client and subcontractor. -
The most recent Drawing Issue Sheet must be displayed where all site personnel can see it.

Acceptance criteria/ Rules of Proper Workmanship 1. No work to be performed unless environmental conditions are as specified in therms of temperature, humidity and wind exposure. 2. Mixing time and proportions must be correct as per specification. 3. Safe systems of work must be enforced for working at height.
