Specifications include, but are not limited to: Henie Hills Reservoir is a nominal 3.0 MG prestressed concrete reservoir constructed in 1960. Approximate reservoir dimensions are 135 feet inside diameter with a wall height of 30 feet. Approximately 5 feet of the wall heights is below grade. The reservoir has a concrete dome roof (self-supported without interior columns). The walls are believed to consist of a 7-inch thick gunite core wall with a 1-inch gunite cover coat with both vertical reinforcement and horizontal prestressing. The floor is believed to be a 3-inch thick gunite slab with welded wire fabric reinforcement. The Work to the reservoir includes: modifications to the footing, wall, and ring girder, additional reinforcement and prestressing, concrete and floor joint repairs; a new concrete floortopping, a new foundation leak detection/ring drain system; buried and exposed piping and valve improvements; improvements to miscellaneous reservoir appurtenances, including hatches, ladders and guardrails, and roof vent; new flowmeters, new level and pressure instruments; recoating the exterior walls and dome roof tank and associated piping and appurtenances; and minor site improvements. Coordination and scheduling of the Work shall require strict adherence to the outage plan.
