The draft report and its supporting documents are usually prepared by the contractor that performed the relevant works.
The contractor must accurately specify the facility, work area, axes, elevations, type of work, design drawings, materials used, measurement results, test results, and documents confirming quality.
However, preparation of the document by the contractor does not mean that the work is automatically accepted. The information in the report must be verified by the technical supervision and designer’s supervision representatives on site.
According to Article 30 of the Urban Planning Code of the Republic of Uzbekistan, the contractor’s internal control includes verification of documentation, materials, construction technologies, and acceptance control of construction and installation works. Material control includes comparison with working drawings, passports, certificates, and quality documents.
First, the contractor completes the stage to be inspected and carries out internal quality control. The contractor then prepares the report and supporting documents, notifies technical supervision and designer’s supervision, and provides access to the structure.
During the inspection, specialists compare the completed work with the design drawings, measure accessible parameters, verify the materials used, review test results, and check as-built drawings.
If no violations are identified, the participants sign the report and authorise the subsequent works.
If deviations are found, they are recorded in comments or a formal instruction. The contractor corrects the deficiencies and presents the work area for inspection again.
A report confirming compliance with the design should not be signed before significant violations have been eliminated.
Verification of concealed works reports consists of two parts – inspection of the actual structure and review of the supporting documents.
On site, specialists assess geometry, dimensions, elevations, materials, quality of joints, compliance with the required technology, and the absence of defects.
The documents are checked for correct details, dates, references to the design, description of the works, precise identification of the location, availability of as-built drawings, certificates, test reports, and signatures of authorised specialists.
Particular attention is paid to chronology. Materials must undergo incoming inspection before use, concealed works must be inspected before they are covered, and the report date must not contradict the actual sequence of construction operations.
As-built drawings confirm the actual position of structures and utility networks.
They show axes, coordinates, elevations, dimensions, reference points, and identified deviations from the design.
The drawing must make it possible to clearly identify the exact area that was inspected. A general drawing without dimensions, elevations, or reference points does not confirm the actual execution of the work.
As-built drawings attached to concealed works reports are especially important for foundations, underground utilities, cable routes, external networks, and other elements that will become difficult or impossible to access after construction is completed.
In addition to the report itself, the contractor may provide working drawings, as-built drawings, material documentation, laboratory test results, measurement reports, work logs, and approvals of design changes.
The set of attachments depends on the type of work and the project requirements. Each supporting document must relate specifically to the work area being inspected.
A certificate for a different material, a test report for another stage, or a drawing without a clear reference to the location does not confirm the quality of the work presented for acceptance.
A document can technically be completed later, but such a report does not confirm that the control representatives actually inspected the work before it was concealed.
If the inspection was not carried out in due time, the client may require additional evidence of quality, further testing, or opening up selected sections of the structure.
Article 676 of the Civil Code of the Republic of Uzbekistan gives the client the right to monitor the progress and quality of the works, deadlines, and materials. If deviations are identified that may reduce the quality of the work, the client must immediately notify the contractor.
Signing a report retrospectively without an actual inspection creates risks for the client, technical supervision, designer’s supervision, and contractor because the document may not reflect the actual condition of the structure.
Professional verification of concealed works reports helps the client identify missed inspection stages, documentation errors, unconfirmed materials, and discrepancies between the actual structures and the approved design.
Specialists compare the reports with design drawings, as-built drawings, work logs, certificates, test reports, and the actual condition of the facility.
As a result, the client receives a list of missing documents, identified violations, comments for the contractor, and an assessment of whether the as-built documentation is ready for acceptance.
Concealed works should be inspected before they are covered and before unconfirmed quantities are paid for. When it is necessary to compare documentation with actual work quantities and costs submitted by the contractor, financial and technical control of construction may additionally be applied.
To arrange technical supervision for the acceptance of concealed works in Tashkent, submit a request on the technical supervision services page.
A concealed works report confirms not only that a construction stage has been completed, but also that it was inspected before being covered by subsequent structures.
A reliable document must be linked to the design, a specific work area, the materials used, as-built drawings, test results, and the actual condition of the facility.
The client should monitor the timeliness of inspections, the authority of the signatories, the accuracy of dates, and whether the documentation corresponds to the works actually performed.
The earlier the acceptance of concealed works is organised, the lower the risk of opening up completed structures, disputes with contractors, payment for unconfirmed quantities, and delays in project completion.
