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. PLANNING AND BUILDING COMMITTEE 44,L AA, • Richard R. Wilcox, Chairman OAKLAND COUNTY EXECUTIVE DEPARTMENT OF CENTRAL SERVICES FACILITIES ENGINEERING DIVISION PHASE TWO OF THE STEAM SYSTEMS IMPROVEMENTS PROJECT 77-34 May 11, 1978 $ 15,000 180,000 20,000 $215,000 $16,000 1,000 3,000 5,000 20,000 45,000 $260,000 , 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.)
