Testing and Site Records

Testing and Site Records

As the Qualified Person (QP) for a building project, you must maintain these essential site and test records and keep them on site at all times.

Forms for recording

You may download forms individually below or as an entire set.

Site and test records


Schedule of structural works

Ensure that a schedule of structural works to be carried out every 3 months is kept on site. It must specify these areas in structural works:

  • Excavation
  • Installation
  • Testing
  • Removal
  • Construction or fabrication of the key structural elements

Attendance record (QP and site supervisor)


Site record book

The site supervisor should also record his time spent at the site and any comments or instructions given.

Approved structural plans, amendments and specifications

The specifications, approved structural plans and amendments must be properly documented and a complete set must be kept on site for use.

Record of all departures or deviations relating to structural elements of the building works


Record of inspection and approval for concreting

  • Ensure that a copy of the approved concrete mix design is kept at the site for verification.
  • Ensure the presence of the site supervisor, himself or both in the section of the structural works before concreting is recorded. You must also record the time taken to carry out the necessary inspection and any comments or instructions given.

Record of repairs to defective structural works


When defective concrete works, such as honeycombs and cracks are detected after the formwork has been stripped, you must record these defects, the remedial measures taken and the type of repairs carried out. Also record the date of the repair and the name of the supervising officer.


Site investigation report


As a QP, you must certify such reports and all soil tests must be carried out by a laboratory approved by the Singapore Accredited Council under the Singapore Laboratory Accreditation Scheme (SAC-SINGLAS). Certain minor in-situ tests such as in-situ penetrometer may be carried out by you (the QP). A copy of the soil investigation and soil tests report must be kept at the site office for reference.


Record of piles installed

(Driven pile and bored pile)

Compile a record of all the piles installed on site in the normal pile record forms. Submit these records to the Commissioner of Building Control (CBC) upon completing piling works.

Record of pile load tests

The records should be in the normal load test record format including the load vs. settlement graphs. The records should also include calibration reports for the gauges. Submit these records to the CBC upon completion of the pile load tests.

Record of tests on cement, sand and aggregates


As a QP, you must:

  • Ensure that a copy of the Cement Manufacturer’s Test Certificate of the approved branch of cement is kept on site for verification.
  • Ascertain the freshness of cement.
  • Instruct the site supervisor to carry out random checks at regular intervals on the quality of sand by performing the field sedimentation test. Decantation or other more accurate methods can be used if the field tests indicate a larger than acceptable silt or clay content. For coarse aggregates, grading and crushing strength tests may be carried out when required.
  • Record the source of supply.
  • Check the source of supply regularly to ensure reliability.

Record of concrete cube tests

You should also record the slump, structural element and location of the batch sample. In cases where the concrete fails to achieve the specified 28-day strength, you must record the remedial measures taken.

Record of tests on steel reinforcements

  • Keep a copy of the mill certificate on site for verification on the strength and quality of reinforcement bars.
  • Record and check the source of supply regularly.
  • Carry our further tests at your discretion at regular intervals.
  • Get a sample of a welded joint tested by an approved laboratory where normal welding is done on reinforcement bars.

Record of tests on prestressing steel

  • Keep a copy of the manufacturer’s test certificates covering each coil to be used on site.
  • Where required, test samples in an approved laboratory and keep all test reports on site.

Record of prestressing works

You must keep these on site:

  • All shop drawings, calculations of theoretical cable extensions and other relevant documents provided by specialist firms.
  • Records of actual site extension measurements including force-extension graphs that are verified by you (the QP). The record should also include calibration report for stressing jacks and gauges.

Record of tests on welding works and all welders’ certificates


Record of all other necessary tests (e.g. Record of Inspection and Approval for Structural Steel Works and Record of Inspection and Approval for Precast Works)


You (the QP) must ensure that records of all other necessary tests are kept. They may be results of core tests, tests on structural steel or non-destructive tests, such as the rebound hammer and ultra-sonic tests. You should also properly file all other site records such as site instructions by other QPs, the resident engineer or site supervisors.
