DESCRIPTION OF PROJECT:

PTTPE Ethane Cracker Project is one of major projects of PTT Polyethylene Company Limited.  It locates in Pha Deang Industrial Estate in Map Ta Phut, Rayong.  The construction has been carried out by Toyo Engineering Corporation (TEC) and Toyo-Thai Corporation PCL since year 2007.  A lot of concrete volume (48,000 m3 in approximate) has been used in this project.   In late of year 2008, it was found that concrete strength of many structures in the project is somewhat lower than the design requirements as specified in the project specifications.   Therefore, PTT Polyethylene Company Limited (PTTPE) requests that the concrete works as constructed shall be reviewed, verified and certified by a third party. International Engineering Consultants Co., Ltd. (IEC), one of engineering firm specialized in engineering design as well as forensic investigation and strengthening design of civil engineering works, was engaged to be a third party for such verification an certification.

SCOPE OF SERVICES:

·        Review background of construction, detailed design drawings, calculation, Engineering Revision Instructions (ERI) or Field Revision Instructions (FRI), placing concrete records, and concrete compressive strength test reports.
