RESOLUTION NO. 8471 May 18, 1978
RE: AUTHORIZATION TO RECEIVE BIDS ON STEAM
SYSTEM IMPROVEMENTS - PHASE II
BY: PLANNING AND BUILDING COMMITTEE
TO: OAKLAND COUNTY BOARD OF COMMISSIONERS
MR. CHAIRPERSON, LADIES AND GENTLEMEN:
WHEREAS, the high pressure steam and condensate lines, running
from the start of the Service Center Loop System and running due West
for approximately 1,000 feet, is thirty (30) years old and is of
inadequate size to handle needed capacity; and
WHEREAS, because of the build-up of scale in the small diameter
pipes, pressure losses have become too great for efficient steam
distribution; and
WHEREAS, this project is included in the proposed 1978 Capital
Program-Utilities Section.
NOW THEREFORE BE IT RESOLVED that the Central Services Department
be and is hereby authorized to receive bids for the above steam system
improvements and a report thereon be made to this Board after receipt
and tabulation of such bids.
The Planning and Building Committee, by Richard R. Wilcox, Chairman,
moves the adoption of the foregoing resolution.

, The Service Center steam distribution system is depicted schemati-
cally on the plan shown on the next page. Live steam is distributed to the
buildings on the system by pipes of varying sizes up to and including ten
inches in diameter. Spent steam, condensate, is returned to the Powerhouse
through four and six inch diameter pipes. Nearly all of this piping is
contained in some 9,200 feet of tunnels. The tunnels vary in cross.-
sectional size from those which must be crawled through to fairly large
areas such as in the spur to the Jail. Tunnels are desirable in that they
provide a means for distributing other utilities (telephone and gas for
instance) and they allow periodic inspections and maintenance to be
performed. The small remaining balance of the steam system is encased in
insulation and buried directly in the ground.
The condition of the system varies. Generally, the older a particular
section is the worse the condition. The system along A-B-C-D-E was built
shortly after the Powerhouse was finished in 1948 and ranks as the oldest.
Thirty years is about the length of the anticipated useful life of a steam
system. Because of its age and the resultant scale buildup in a
relatively small diameter pipe, pressure losses have become too great for
efficient steam distribution. Further, inoperative expansion joints and
overstressed anchors have rendered the system hazardous.
Work under this project would include the replacement of the existing
six inch steam line and four inch condensate return with new ten inch and
six inch piping. Also included would be new anchors, expansion joints, and
numerous valves. Valves would allow sections of the system to be closed
for maintenance or buildings to be isolated for remodeling while still
keeping the rest of the system in operation.
The settion of system along EeF-H-I, although undersized, is not quite
as old and will still provide marginal service. With the proposed changes,
a failure at the worst possible place, say between B and Q, service to the
furthermost place, the Jail at P, can still be maintained.
It is being recommended that the necessary design work be completed
and authorization be given to advertise and receive bids. This project is
among those in the Utility Section of the proposed 1978 Capital Improvement
Program.
The total project cost is estimated as follows:
CONSTRUCTION
Demolition of existing piping
New supply and return lines
(approx. 1,000 ft.)
Miscellaneous joints, anchors,
valves, & fittings
