Scope of Work

We were contracted to perform installation of new rock anchors to update an existing flood control dam.

Challenges

In Spring 2014 we were contacted to provide proposal for what appeared to be a handful of rock anchors 25 feet off the paved road. During the site visit it became very clear the OH Power and site geometry was not going to allow standard drilling equipment. There was no method to effectively use a crane for any significant portion of the work site without a power outage, which could have delay the project past its required completion date. We worked with the General Contractor and Engineer/Owner to negotiate acceptable anchor locations where both the drilling and the access platform construction could be constructed without any significant hoisting.

Outcome

The final design required 4.5? diameter holes x 45 foot at 4:12 batter. We mobilized limited access drilling equipment and worked from staging, using chain falls and pulleys to move around the 1000 lb drill frame and get the 45 foot anchors installed. MD&B met the schedule and completed our work safely. We successfully turned over the site to the general contractor with the time they needed to finish the structure rehabilitations.

Customer Comment

Now that the work is complete in Oakland, I wanted to take a moment and let you know how pleased we, the owner and engineers were with the work that was performed by your team at Oakland on the recent anchor project. I realize this was a relatively small project for your firm and did not expect the level of professionalism and attention to detail it received. Being a manager and details type person I thought it was important to let you know that this type of service does not go unnoticed.?"
