WEST DAM HYDROELECTRIC, Potsdam, NY

SCOPE OF WORK:
Upgrading existing hydro facility.  Installing rock anchors at existing dam.  Drilling and blasting immediately adjacent to existing dam for new intake, tailrace, and turbine generator.

CHALLENGE:

• Working in very close proximity to existing dam.
• Working behind a cofferdam installed to divert water away from work area.
• Working to high tolerances on both rock removal and vibration criteria.

OUTCOME:
Work completed safely and on schedule.

SUMMARY:
Detailed planning and logistics, along with a team approach, result in a quality, safe project.

STETSON WINDMILL PROJECT, Danforth, ME

SCOPE OF WORK:
Thirty-eight wind towers accessed with 9 miles of road. This road provides access for the erection crane that travels 32 feet wide and 250 feet tall as it moves from tower to tower.

CHALLENGE:

• To design a road that worked with contours and allowed the crane the appropriate grades and radii.
• Install competent rock bolts for the foundations with their huge wind loads and marginal geotechnical conditions.
• Start the project in the winter of 2008 with roads and foundations complete by June.

OUTCOME:
The team met the challenge by blasting through 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:
The schedule was achieved throughout the winter construction in Northern Maine.

SUMMARY:
The team has built the two wind farms in Maine and is ready to accept the challenge of other wind farms.

Stetson Windmill Project,
Danforth, ME

WINDMILL PROJECT, Lempster, NH

SCOPE OF WORK:
Twelve 2 MW Wind Turbines in Western NH.  Drilled and blasted rock through Winter and Spring 2008 to construct mountain access road for installation and maintenance of turbines.  Installed 216 rock anchors for foundations.

CHALLENGE:

• Drilling and blasting an access road through mountainous terrain in an unforgiving geology.
• Drilling and blasting and installing rock anchors in Winter and Spring conditions.
• Working through a snowfall that was nearly twice the average for that particular region to maintain an aggressive schedule.

OUTCOME:
The team met the challenge by drilling and 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:
A late January start to accomplish access for tower erection in June.  The roads and foundations had to be constructed and ready to receive tower pieces in June allowing the summer months for the heavy rigging involved with constructing the turbines.

SUMMARY:
We were participants in the construction of the first commercial wind power facility in New Hampshire.  We accomplished a difficult project and strengthened our connections with our teammates/customers.

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.

WINDMILL PROJECT, Princeton, MA

SCOPE OF WORK:
Two wind towers required road construction for the upgrade of a local utilities’ alternative power source.

CHALLENGE:

• To design and build a road which met an aggressive budget while providing adequate access to allow delivery and assembly of towers.
• Creative location and construction of roadway and foundations to put the towers in the most effective location while minimizing excavation.
• Performing drilling and blasting activities adjacent to an environmental conservation area.

OUTCOME:
The team accomplished the road construction with an evolving design.  A rock anchor design was implemented which minimized the size of the foundations.

SCHEDULE:
Work was completed in rainy months of the Fall in order to get the project closed up prior to the Winter months.

SUMMARY:
This project’s success contributes to a progressive utilities’ vision of providing local alternative energy.

WINDMILL PROJECT, Portsmouth, RI

SCOPE OF WORK:
Single wind tower rock anchor installation at local high school.

CHALLENGE:

• Economical means of constructing alternative energy project.
• Minimizing impact to high school campus.

OUTCOME:
The team completed the installation on schedule and safely.

SCHEDULE:
Work was completed in Summer months between high school classes and sporting events.

SUMMARY:
This town’s innovative and progressive use of its resources provide alternative power.

WINDMILL PROJECT, Hull, MA

SCOPE OF WORK:
One turbine on landfill site.

CHALLENGE:
To design and build a suitable foundation in a landfill.

OUTCOME:
Piles by another contractor; rock bolts through piles by Maine Drilling & Blasting.

SCHEDULE:
Work was completed on a four-week schedule.

SUMMARY:
Hull, MA is more independent for power.

WINDMILL PROJECT, Altona, NY

SCOPE OF WORK:
Sixty 2MW Wind Turbines near Plattsburgh, NY.  Drilled and blasted rock in Spring 2008 to construct foundations for installation and maintenance of turbines.

CHALLENGE:
Drill and blast 2 foundations per day as contractor removed the overburden.

OUTCOME:
The team met the challenge by blasting in close coordination with the general contractor.

SCHEDULE:
The work was finished July 2008, as the schedule required.

SUMMARY:
Spread footer foundations required considerable blasting to accomplish 2 towers per day.

UNH/Turnkey Landfill Bio Gas Line, Durham, NH

SCOPE OF WORK:
R.H. White installed 12.7 of miles Methane Gas Transmission Line with Maine Drilling & Blasting performing the drilling and blasting. The project connected the Turnkey Landfill in Rochester, NH with the University of New Hampshire Co-Generation Facility.

CHALLENGE:
The work was along a busy highway easement with several structures surrounding blast areas.

OUTCOME:
Maine Drilling & Blasting performed all the blasting on time and safely.

SUMMARY:
We participated in this innovative project using waste gas from a landfill as fuel for a power boiler at the University of New Hampshire.  The gas is considered a “Greenhouse Gas” and previously it was collected and burned off as it was emitted from the decomposing landfill material.  This project built the infrastructure that created the opportunity to collect and transmit this gas for use as fuel to make power and steam.
