Design
and Procurement. This involves a site investigation, drilling into
the ground to determine soil and rock formations where the turbine foundations
will be placed, design of turbine foundations, Operations and Maintenance
Building, electrical conductor routes, roads, securing permits such
as Storm Water Pollution Prevention Plans, National Pollutant Discharge
Elimination System, Building, Electrical, Utility Crossings, Gravel
Pit, and Air Discharge for Gravel Crushing. Construction.
Overlapping design and procurement is the actual construction process.
The first construction activities were clearing for the Operations and
Maintenance Building and surrounding area where the construction contractors
have located their offices and marshalling areas. In this vicinity work
has also begun on the Project substation. Road
Construction. This involves road construction within the Project
area and reinforcement of the local County roads leading to the site.
Even though these are County roads, the reinforcement is for the purpose
of the Project and thus paid for by the Project. Work has begun on the
project roads and the bulk of the reinforcement of the local County
roads has already been completed. Crane
Pad Construction. As soon as road construction has progressed sufficiently,
foundation and crane pad construction will begin. Because the turbines
are so large, 420 feet tall at the peak of the blade, a large level
area is required for positioning the crane to lift the turbine components
into place. The total lift capacity for this crane is 400 tons, which
far exceeds the total weight of the turbine components, but is required
due to height of the lifts involved. Electrical
Cable Installation. Follows road construction as all electrical
cables from the turbines to the Project substation will be buried underground
to eliminate air flow interference and minimize perching opportunities
for birds within the Project boundary. Turbine
Delivery & Erection. After roads, foundations and underground
cables are in place, cranes arrive to erect the turbines. The cranes
are sufficiently large that they must be brought in pieces, a total
of nine semi truck trailers per crane, and then assembled on site. Each
turbine takes about two full days of crane time to erect. Commissioning
Crew Evaluation. Commissioning crews come in to complete all the
electrical connections inside the towers and to "wring" out
all of the various functions of the computer controls for each turbine.
To fully evaluate the function of the turbine, commissioning crews must
wait for windy conditions over fixed periods of time to ensure all systems
are working properly. Project Completion. As you can see from the schedule total time from initial road construction to final completion is expected to take just over one year. Click
