This tender is for Contract No. 13/2016 - Blacktown Aquatic Centre - Pool Water Treatment Plant Replacement for Blacktown City Council with the method of payment being Lump Sum notsubject to Rise and Fall in costs.

The existing facility features three pools; 1 No. Indoor 50m x 8 lane pool, 1 No. Outdoor 50m x 6 lane pool and 1 No. Outdoor toddlers / learn to swim pool.

All pools are serviced by a single pool water treatment plant. The treatment plant features gravity sand filtration, chlorine disinfection with bulk delivered sodium hypochlorite and pH correction with hydrochloric acid.

The existing pool water treatment plant is in poor condition and needs to be replaced. The existing pool plantroom is also in poor condition and contains asbestos roof sheeting and linings. The existing plantroom shall be demolished by Council after the completion of the contract works. This project includes the replacement of the existing pool water treatment plant with two new pool water treatment plants; 1 No. 500m³/hr plant for the 50m pools and 1 No. 80m³/hr plant for the toddlers pool.

The scope of work includes all necessary building work to construct a proposed pool plantroom and artial demolition of existing structures.

The pool hydraulics for the 50m pools cannot be separated in the existing plantroom area (or any area that can be accessed). The proposed pool water treatment plant combines the two 50m pools. The pool hydraulics for the Toddlers pool can be separated (access to both soiled water return and filtered water supply) proximate to the existing plantroom area. A dedicated pool water treatment plant is proposed for the Toddlers pool to allow isolation between the pool volumes in accordance with NSW Health best practice guidelines. This arrangement will also allow the Toddlers pool to operate at differing temperatures and water chemistry parameters.

The site is a former rubbish tip and is likely to contain asbestos.

All tendered lump sum prices shall be inclusive of GST.
