This work request involved DIS working along with the pump station construction contractor to provide a superior product to our client. DIS performed all the staking, as-built survey and permanent control establishment in the pump stations. Work consisted of laying out piling locations and bolt patterns with tolerances of 1/16th of an inch, providing a seamless fit when the offsite assemble piping was brought onsite. DIS also performed the final as-built survey for these pump stations, as well as the final redline facility drawings. Permanent control monuments were established at the owner’s request in each pump station and protection was put in place to preserve their accurate locations.
We have found DIS to be the best working group in this field of contractors and highly recommend them. All staff are prompt and perform their individual tasks utilizing the latest equipment in the field.Ed Kelly, Storm Water Control Services, LLC
