3.2 PLUMBING

Upgrades and replacements of plumbing fixtures and systems generally will consist of upgrading specific parts or accessories to extend the service life of existing equipment. Replacement of many systems is not recommended outside of regular maintenance activities. Recommendations for individual systems are described below.

3.2.1 Domestic Hot Water Systems

Domestic hot water heaters in most buildings have exceeded their expected service life. Domestic hot water recirculation pumps in the Maintenance, Administration, and Fleet Services buildings have also exceeded their expected service life. Replacement of water heaters and recirculation pumps is recommended along with installation of new code required thermostatic mixing valves (TMVs) in buildings that do not require high temperature domestic water (in excess of 120°F). On a building-by-building basis, the recommended work will include:

 Maintenance Building, Administration Building, and Fleet Services Building

o Replace existing water heater with new electric commercial grade water heater with similar tank size and heating element capacity.

o Provide a new TMV, set to 110°F.

o Reconfigure cold water, hot water, and hot water return connections to the new water heater to accommodate the TMV.

o Replace domestic hot water recirculation pump.  Warehouse, Buildings C, D, and F

o Replace existing water heater with new electric commercial grade water heater with similar tank size and heating element capacity.

 Building H

o Replace two existing water heaters with new natural gas water heaters with similar tank size and capacity.

The approximate construction cost for plumbing work in this category would be $26,800. 3.2.2 Piping

Extensive replacement of plumbing piping is not recommended. Repair of plumbing piping on a case-by-case basis as breaks or failure occurs is preferred as part of regular maintenance activities.

No cost estimates were prepared for this section. 3.2.3 Fixtures

Recommended upgrades or replacement of existing fixtures are discussed by type below. 3.2.3.1 Water Closets and Urinals

Since water closet and urinal fixtures are in good condition and have a long working life, replacement of these fixtures is not recommended. Replacement of existing flush valves with modern flush valves having a lower water use is not recommended without complete replacement of the associated fixtures, as the existing fixtures will not perform properly with low flow valves. A simple financial analysis showed that replacing existing valves and water closets

with new low volume fixtures does not recoup investment cost within the life of the fixture. We recommend gradual replacement of fixtures when required as part of regular maintenance activities.

No cost estimates were prepared for this section. 3.2.3.2 Lavatories

Lavatory fixtures are in good condition with a long working life, but faucets, trim, and drain piping will need eventual replacement. Replacement of existing lavatory faucets with battery- powered low flow sensor faucets and replacing of existing lavatory drain piping is recommended. For the Maintenance, Administration, Fleet Services, and Warehouse buildings, and Buildings F and H, work for each lavatory includes:

 Remove the existing lavatory faucets, and install new battery-powered sensor faucets.  Replace the existing lavatory drain, tailpiece, and p-trap.

The approximate construction cost for plumbing work in this category would be $32,800. 3.2.3.3 Wash Fountains

Wash fountains are in good condition, and the installed fixtures are known to have a long working life, but trim and valves will need eventual replacement. Replacement of wash fountain components as they fail is recommended as part of regular maintenance activities.

No cost estimates were prepared for this section. 3.2.3.4 Sinks

Sink fixtures are in good condition with a long working life, but faucets, trim, and drain piping will need eventual replacement. Replacement of existing sink faucets with manual gooseneck faucets with low-flow aerators and replacing of existing sink drain piping is recommended. For the Maintenance, Administration, Fleet Services, and Warehouse buildings, and Buildings F and H, recommended work for each sink includes:

 Remove the existing lavatory faucets, and install new battery-powered sensor faucets.  Replace the existing lavatory drain, tailpiece, and p-trap.

The approximate construction cost for plumbing work in this category would be $8,200. 3.2.3.5 Showers

Shower fixtures have recently been replaced in the Maintenance Building, but existing showers in the Fleet Services Building will eventually require replacement. We recommend replacing the existing showers and upgrading the Fleet Services shower area to meet ADA requirements. The recommended work includes:

 Remove the existing shower fixtures.

 Reconfigure the existing shower area and shower anteroom to meet ADA requirements.  Install one standard wall mount shower assembly with low flow head.

 Install one ADA wall mounted shower assembly with low flow head.

3.2.3.6 Miscellaneous Fixtures

Drinking fountains, mop sinks, eyewashes, and drench showers are in good condition, and the installed fixtures are known to have a long working life. However trim, valves, and faucets will need eventual replacement. Replacement of components for these fixtures as they fail is recommended as part of regular maintenance activities.

No cost estimates were prepared for this section. 3.2.4 Fleet Services Shop Compressed Air

Replacement of the existing refrigerated air dryer, the lag compressor, the air filtration manifold, and piping distribution system low points, as well as addition of a compressed air pre-cooler and installation of drains at distribution system low points are all recommended upgrades to the existing shop compressed air system. Work includes:

 Remove the existing refrigerated air dryer, lag compressor, and air filter assembly.  Remove distribution piping in the office area and the bottom six inches of all compressed

air outlet piping drops.

 Install a new refrigerated air dryer with similar capacity to the existing dryer.  Install a new air-cooled pre-cooler for the refrigerated air dryer.

 Install a new 25-HP reciprocating air compressor.  Install a new air filtration manifold with coalescing filters.

 Replace distribution piping in the office area, reconnecting to existing piping in the light and heavy bay areas.

 Replace air outlet piping drops and fittings.

 Repair air leaks in the remaining existing distribution piping.

The approximate construction cost for work in this category would be $46,700. 3.2.5 Fleet Services Oxygen and Acetylene Distribution System

The existing Oxygen and Acetylene distribution system located in the Fleet Services heavy bay has been abandoned in place for several years, and there are apparently no plans to use the system in the future. At the Owner's discretion, the existing distribution manifolds and piping could be decommissioned and removed.

The approximate construction cost for demolition of this system would be $5,400. 3.2.6 Plumbing Cost Summary

Estimated plumbing costs are summarized in the following Table 3.2. Direct construction costs include contractor costs only and do not include Owner expenses such as management, staff relocation, and similar items. Design fees are budget prices only and may vary significantly from the figures shown depending on the method of implementation and the exact services required by the Owner.
