Mr. Camardella introduced the New Kodiak Island Hospital design team of Mills,
John & Higdon and Coffman Engineers: Jonathan Higdon, Architect; Craig
Comartin, Civil/Structural Engineer; Ed Langebartel, Mechanical Engineer; and
Joel Eide, Electrical Engineer.
The overall design concept was explained by Mr. Higdon. He detailed the
contents of the 44-bed structure. The assembled group then addressed the
technical items which had been questioned:
Slab on Grade vs Crawl Space - Mr. Chase spoke in support of using a crawl
space because of the versitility it allowed the contractors and staff in laying
lines, making adaptations, etc. He felt the project would be done earlier and
be more labor efficient if crawl space was incorporated in the design. Mr.
Ford supported the concept from an electrician's point of view. Mr. Heinrichs
commented the crawl space would eliminate placing ladders in halls, cutting
trenches in the floors to seek sewer problems, and, if a sewer back up occurs,
potential rivers in the halls.
Stan Thompson, K I Hospital Maintenance Department, stated the overhead lines
in the current hospital are a nightmare. They cause difficulty in running
anything required by new technology. He felt a five (5) foot crawl space was
not high enough and recommended an eight (8) foot space. Mr. Wheeler felt the
points for a crawl space were well made.
Mr. Rigdon indicated the ceilings in

Mr. Comartin stated it would take from six to nine months after ordering
structural steel for a crawl space for it to arrive on the island. The design
team feels the crawl space would add to the initial cost and extend the time of
construction. Addition of a catwalk in the waste space above was discussed as
an alternative
to a crawl space. It was agreed
lighting and convenience
outlets would
also be advantageous. The
board members were split between
crawl space and
slab construction, but all
agreed the
catwalk alternative was a
good one.
Roof Design - Mr. Heinrichs was concerned with the valleys in the roof filling
with ice and snow in the bad weather. Mention was made of the possible use of
Snojax to eliminate slides. Mr. Rigdon mentioned the addition of roof drains
and the fact that the slope in the roof design should take care of the buildup.
Mr. Thompson indicated the roof drains on the present hospital are two (2)
inches and plug up in three (3) months with spruce needles and dust from the
Katmai Volcano eruption of 1912. There was discussion of placing drains over
the heated area and the use of lead coated heat tape in down spouts with manual
turn on/turn off to eliminate the ice damming.
Storage Space - It was generally agreed there was little room for designing
more storage.
Snow Mats - Snow mats for ice and snow removal were eliminated from the
original concept drawings. The drainage problem beyond the end of the mats and
the cost were two main considerations. The consensus of those present was to
put in electric snow mats at the main, emergency and ICF entrances as an
alternate.
Incinerator - It is hoped the
need for an incinerator
will be eliminated by an
alternate plan which is under
consideration. Present
hospital usage is about
-
100 pounds a week. The incinerator will be eliminated from the design.
Number of washers and dryers - Plans include two washers, which will handle 135
pounds each and four electric
dryers which will handle
110 pounds each.
Electrical Service Size - Mr. Ford questioned whether the size of the standby
generators was too large. Mr. Ride indicated there are three areas of power
which are critical in a power outage: 1) life safety load, 2) critical power,
and 3) essential equipment. These are required to be backed up by one
generator. The second generator would increase the capacity to carry the
additional load of other areas of the hospital should a prolonged outage occur.
Reduction of the size of the generators is a possibility and would result in
considerable savings.
Boilers, Size, Number, etc - Plans call for three (3) oil fired boilers. Each
boiler is capable of handling 50 to 60% of the load. The third boiler would be
used for backup. Hot water lines are served by the boilers with room water
mixed down to 140 to 120 degrees. The steam required for hospital use is
generated by electric boilers. Discussion centered on the use of low pressure
boilers with a heat exchanger, high pressure boilers and hot water boilers. It
was felt there might be a logistic problem with a split system. Discussion of
fire tube vs cast iron pipe indicated that fire tube is acceptable. It was
decided that a LP steam system with electric steam only source for the
autoclave was the most economical system, saving $140,000 in annual operating
costs.
CControl System - Pneumatic vs Electronic was discussed. The pneumatic systems
C
C
s
have been the workhorse for years while the high tech electronic systems are
becoming less expensive. A hybrid system was discouraged. Generally the
direct digital controls (ddc) (electronics) are more versatile and received the
consensus vote.
Fuel Tank - The plans call for a double walled tank with leak detection. It
meets EPA requirements. The specs currently do not specify the type of
material and will be revised to be fiberglass.
Cabinet Unit Heater Schedule - Is to be added. This was an omission by the
Mechanical Engineer.
Sewer Main Design - The design slope is one (1) percent minimum. There was
some concern expressed over disposing of some existing lines.
This discussion ended at 10:15 p.m.
Mr. Camardella provided, to those board members present, copies of the four
proposals for the wastewater and water supply facilities feasibility studies
presentations which will be made at the meeting at 6:30 p.m., Monday, May 14,
in the Assembly Chambers. He explained the selection/evaluation criteria and
reviewed how the contents are set up. He asked the board members to write down
any questions they might have for presenters on Monday night and be prepared to
ask those questions then.
The group informally discussed the CT scan building and the Chiniak
Tsunami/Library Center.
The group left the meeting at 11:00 p.m.
