Esolution construction and Engineering have taken extra mile for Qaulity assurance for bridges work, whereas Esolution been requested to test the anchorages as supplied to the site for post-tension girder work, samples been collected from Supplied ETA Approved posttension Kit to the site and resent to Europe Lab for testing according to ETAG013 and AASHTO Requirements.
The Testing has been completed and approved by the consultant for the project, esolution is approved Supplier and Applicator for posttension concrete work for bridges by ministry of transportation in kingdom of Saudi Arabia, Additionally Esolution serves in Egypt same field and being approved by national transportation of Authoritiy in Egypt for posttension concrete work supply and installation
Actual material characteristics of components been used for testing (mechanical, chemical, metallurgical, geometrical, etc as relevant) shall be determined and documented (see “The provision of data for assessments leading to ETA”, [8]), and shall comply with the ETA applicant’s specification. Test results been submitted by the ETA system owner for verification.
PT system testing has been documented with a test report including the following information:
- A signed statement by the laboratory or body which has carried out or witnessed the tests that these tests have been carried out in accordance with this ETAG.
- Certificates of all relevant materials to confirm compliance with relevant specifications. Actual characteristics of components (mechanical, chemical, metallurgical, geometrical, etc as relevant) at time of testing, and source of manufacture. These include in particular tensile elements, anchorage components, ducts, filling material, reinforcement, and also concrete (or steel, masonry, or timber).
- Certificates of equipment and test machine calibration.
- Description and drawing of test specimen with actual dimensions.
- Description and drawing of test set-up and measuring equipment including calibration certificate.
- Description of detailed test procedure.
- Record of all measurements and observations.
- Photographs of test specimen prior, during, and after testing.
- Date and place of testing.
- Name and signature of person responsible for testing.
- All tests out of a series performed to obtain an ETA shall be recorded in the test report
- Test results been found satisfactory and approved
