Reference: Pin Pile Quality Assurance for Retaining Wall
30 NE Anchor Court, Belfair, Washington
To Whom It May Concern:
Envirotech Engineering has completed an inspection of the installation of pin piles for the
referenced project. A total of 36 pin piles were driven on June 91h 101h 11th 2021 by McDowell
N.W. using a TB-125 hydraulic hammer. The 2-inch diameter, schedule 80 galvanized pipes
were driven to depths between 5 feet and 17 feet below the ground surface. Enclosed is a pile
location map, and inspection sheets.
Based on our observations, it is our opinion that work was completed in compliance with the
required plans and specifications.
Thank you for the opportunity to work on this project. If you have any questions or need any
further assistance, please contact Michael Staten at 360-275-9374.
Sincerely,

Driving of the 2-inch diameter pipe piles were completed in a staggered orientation, and in our
opinion this orientation meets or exceeds the piles placed at two (2) pile spacing increments.
