14. PARTIES INVOLVED IN THE WORK TO ENSURE QUALITY  PARTY – I: Project Engineers  PARTY – II: Construction Agency  PARTY – III: Quality Assurance Consultants

15. CONTRACTOR AND PROJECT ENGINEERS PROJECT ENGINEERS:  are primarily responsible for Quality Assurance of the work being executed and to conduct all field tests before allowing further work. Shall check and produce to inspecting officers the following records and O.K. Cards maintained by the Construction Agency.

16. a) Registers:- 1.Site order. 2.Register of Bench Marks 3.Material O.K. Register. 4.Register of foundations. 5.Register of placement for concrete, Embankment, Reinforcement and other test reports. 6.Register of test reports of compressive strength of concrete specimens. 7.
