| Inland protects from Northern Exposure
Project: Alaska Nitrogen, Kenai, Alaska
The challenges of coating one of the largest roofs in Alaska were many and
varied. The location just north of Kenai in Nikiski, directly on the bluff
above Cook Inlet, makes it a very high profile job. As work on this initial
1,575 square job began, another building of 543 squares was added to the
project.
Initial contact was with DeWayne "Sonny" Meese of UNOCAL who determined the
parameters of the job. Further discussion with Rocky Doty, Maintenance
Engineer for Alaska Nitrogen products, made the project a reality. Securing
the services of Dunkin & Bush Inc., a large painting and coatings contractor
with a sixty plus year history of business in the Pacific Northwest &
Alaska, made the project come together.
Before actual work could commence, safety issues had to be addressed.
Twenty ton concrete anchors were placed around the perimeter and safety
lines laid across the peak. Workmen could then fasten their safety harness
to this line. A wooden 2" x 4" was attached along the eave to allow
friction-free movement of the lines and hoses, eliminating possible
chaffing. Through different phases of the job other systems were employed.
Scaffolding was erected to the eave and securely tied off. This was the
main access to the very large, 30 foot eave and approximately 105 foot
ridge, roof system. The pitch is eight in twelve. The building is 640 feet
long by 210 feet wide. On occasion, man lifts and a crane with an aerial
basket were used.
Once the scope and specifications of the job were established, the pertinent
challenges had to be addressed. Timing is critical as the application
window historically is May 15 to September 15, and even that is a bit
optimistic. Weather is frequently foggy, misty, rainy and windy with
prevailing breezes off Cook Inlet. Inland's rapid drying characteristics
are
a definite plus with Alaskan weather. Inland products also have high
tensile strength and elongation, allowing them to accommodate not only the
movement of the building from the temperature extremes, but also from the
nearly daily earthquake tremors common to this area.
Dunkin & Bush arranged shipping of Inland products through Seattle based Lynden
Transport, which serves all of Alaska. From the shipping department
at Inland's Adel, Iowa plant, Lynden made a fast pick up and delivery to
Dunkin & Bush facilities in Nikiski.
This being an initial project for Dunkin & Bush, on site training and
inspection was initiated. Henry Haney, Dunkin & Bush's Alaskan manager of operations
and his crew, have extensive experience with the challenges of weather and
timing presented in this climate. Spring temperatures hover in the high
30's to low 40's and roofs achieve acceptable temperatures of 70 to mid 90's
by 10:00 A. M. All dew and mist has generally disappeared by then. The
contractor was well prepared with drum heaters as needed. Dunkin & Bush
technicians kept a constant vigil on ambient air temperatures, roof
temperatures and humidity to assure a consistent quality of application.
The huge warehouse facility is for
storage, prior to shipment, of processed urea chemical fertilizer. It is
imperative that the product stays dry, as moisture makes
it solidify into clumps, which renders the product unusable. As there is no
way to dispose of damaged product, it must be reprocessed at a greater
expense than producing it new. A two coat system was used with all seams,
fasteners and penetrations addressed with Inland's RC-2200 Rubber Seam
Compound. For
re-enforcement, Inland RPM polyester mesh was used on all horizontal and
vertical seams and assured the integrity of the completed project. The
entire roof was then coated with RC-2000 Rubber Roof Coating. Two field
coats were applied at the rate of one gallon per-square per-coat.
Actual work began mid-May of 2000 and was completed August 2000. Many times
projects like this have unforeseen residual benefits. The efforts of
Inland's sales and technical departments brought Dunkin & Bush, the
contractor, and Alaska Nitrogen Products, a division of UNOCAL, together on
this very successful project. This has resulted in Dunkin & Bush becoming
the prime painting and coatings contractor for this 200 acre facility.
Kenai operations have since been sold to Agrium Chemicals, based in Calgary,
Alberta and the maintenance program is ongoing. Several smaller projects
specifying Inland products are on tap for 2001.
Incidentally, shortly after the job completion, the area was hit with 16
consecutive days of hard driving rains. UNOCAL said this period was the
first time in many years that this 30-year-old metal roof suffered no leaks.
As a result of their product not suffering any damage, UNOCAL estimates
the entire cost of this job will be recovered in production savings in 12 to
18 months.
