Supervisor: Samrat Srabua Project Engineer: Prakash Singh Rawal Date: Dec 9, 2012.

Perform steel surface preparation

according to Sa 2 as defined by ISO

8501-1 (Shotblasting)

Replica tape testing for 5 location per

beam for first 5 beams and 1 locationfor each beam afterwards

Steel member thickness with Ultra

Thickness Guage after shot blasting

calculation of steel loss will be

submitted.The required additional steel

plate will be welded as per calculation

to the beam sections.Refer to work

procedure flow chart.After that start of

coating of entire one beam.

Check no visible rust on steel surface

and steel surface is free from dust and

other friable matter.

Check material quantity per area

that the theoretical value of dry filmthickness for each of 170micron

coatings consumes approx. 0.24

Check substrate temp. > 3C above

dew point, humidity should be 80%

Allow coat to cure based on minimum /

With reference to the various Check listed above, Sika confirms with its signatures that, based on its respective site visits

on the dates indicated above, the application of the above mentioned Sika products has been effected in accordance with

Sikas written recommendations; Sika has not detected any visible defects in Sika's products as applied. However, the

above confirmations are based only on a visual check of the actual status of the job site and the works executed as seen

during Sikas site visit. Sikas responsibility is therefore limited to the results of its visual check and does not imply anyfurther responsibility as to Sika's products, and/or their correct application by any third party.
