l REQUEST FOR PROPOSAL 2 ENGINEERING WORK TO BE DONE AT ANIMAL SHELTER, CHAPEL HILL AND AT THE NORTHERN HUMAN SERVICES CENTER CEDAR GROVE. Orange County seeks a single proposal for provision of design services for projects at two sites owned by the County. The design services shall be provided by a professional engineer or engineering firm with expertise in the field of plumbing and mechanical design and construction. The two project sites requiring design services are a) the Orange County Animal Shelter which is located within the Chapel Hill Public Works compound on Airport Road/NC Hwy. 86 in Chapel Hill; and b) the Orange County Northern Human Services Center which is located on NC Hwy. 86, approximately ten miles north of Hillsborough. ANIMAL SHELTER The Animal Shelter is a single story slab on grade concrete block building which has been expanded in two phases over the years. The facility contains office and meeting space, storage, rooms with small animal (cat) cages, kennel areas, etc. Most of the floor space area within the shelter is used for the kennels. This area consists of a number of individual dog pens, each with an interior and exterior component. The pens are separated on the sides by either a concrete block wall or chain link fencing. The interior and exterior components of the cages are separated by a concrete block wall containing an opening which may be covered by a drop sliding metal panel or door. All pens are fronted by interior aisles. The interior and exterior component of each pen contains floor drains which discharge through a drain piping network into the sanitary sewer system. In the older sections of the building, the pen floor drains were designed to collect and remove floor wash water and storm water. In the newer section of the building, the pen floor drains are used not only to collect wash and storm water, but as a receptacle for disposal of fecal material, hair, straw and other solid waste during the cage cleaning process. The Shelter has two problems, one of which is generating public complaints and the other of which is causing operating difficulties and hardships on shelter staff. Kennel floor drains in the older section of shelter require frequent plumbing service as they tend to become clogged with solid waste. In addition, kennel staff have become accustomed to flushing solid waste directly into the floor drains during cleaning operations in the newer kennel areas and wish to be able to clean the older cages in a similar manner. The problem generating public complaints stems from the washing out of the animal cages in animal control vehicles. Although animal control officers remove and dispose of most solid prior to the vehicle wash down, some solid material and all wash water streams down a concrete and asphalt drive, crosses a service road and ponds in the gravel parking area of the adjacent solid waste convenience center. The ponding of water is objectionable to convenience center operators and patrons. The proposed solution to the Animal Shelter problems requires retrofitting the drainage systems. The solution to the animal control vehicle wash water problem consists of intercepting the water by means of installing less than thirty feet of cast iron grated precast polymer-concrete trench drain across the existing asphalt and concrete driveway. Installation of approximately thirty feet of small diameter drain pipe (and possibly a junction box) will be sufficient to connect the trench drain to an existing storm sewer. The solution to the floor drain problem, which is significantly more complex, involves a retrofit installation of approximately 40 floor drains and associated drain piping. The new floor drains and drain piping were configured and sized to provide for the removal of wash water, storm water and solid wastes without stoppages. Installing the new system of floor drains and piping will require: a) demolishing and replacing sections of the existing concrete floor slab as required to
