 with MD Drilling & Blasting since
the
late '90s for site work from commercial buildings to
condominium developments and
residential projects. We used to
have our own drilling & blasting company,
so we know what it takes
to do it
right. They are
professionals who
are just
so easy to work with!”

WINDMILL PROJECT, Mars Hill, ME
SCOPE OF WORK:
Twenty-eight wind towers at an elevation of 1,800 feet required road construction for the largest crane in the Northeast to move from tower to tower.
CHALLENGE:
- To design a road that worked with contours and allowed the crane the appropriate grades and radii.
- The foundations have huge wind loads and had marginal geotechnical conditions.
OUTCOME:
The team met the challenge by blasting through huge topographical features to create both the material needed and the grades required. The foundations were accomplished with the highest capacity solid rock anchors available.
SCHEDULE:
With the final permits in place in Spring, the work had to be completed before severe winter conditions. An 18-month schedule was compressed to 9 months.
SUMMARY:
The project’s success will give Maine people more jobs on future projects, as well as more green power.

MILLENNIUM PIPELINE, Phase I 2007, Tuxedo, NY
SCOPE OF WORK:
12 miles of 36-inch gas line was installed by Precision Pipeline with MD Drilling & Blasting performing all blasting. The work connected Tuxedo, NY to Ramapo, NY.
CHALLENGE:
- This is very rugged terrain near I-87 through the hills just below the Catskill Area. Many areas need to be preblasted above the trench to allow access for construction traffic.
- The ROW width and environmental constraints, along with difficult access, were significant. Much of the ROW blasting was right up against the Wetlands, and, for much of the project, we worked with the pipe laying crew on both sides of us so we had no access by them back to the road.
- Material planning for a productive day was essential.
OUTCOME:
The pipe contractor needed 1,000 running feet per day. It was ready for them, while we adhered to the environmental constraints as well as traffic requirements along the busy interstate highway.
SCHEDULE:
We needed from one to eight drills with appropriate blasting crews to meet the productions. Our Project Superintendent had access to whatever he needed to keep up.
SUMMARY:
The pipeline contractor is now planning the next 75 miles. We are looking forward to keeping them as another repeat customer.
