2.1 Background

• Sewer system – a sewer line has been experiencing regular blockages during 2019. It has been determined that there is serious tree infiltration, with uneven line runs which holds waste in old glazed earthenware reticulation. The line runs under buildings which makes it impossible to replace.
• Storm water system – the storm water system has also been experiencing problems with increased flooding. This has caused water to back up into the courtyard area between Blocks A and B. Part of the storm water system runs into the sewer system which the Wairoa District Council wants rectified immediately. There is serious tree infiltration near the boundary along with blockages and multiple holes in the old glazed earthenware reticulation. Other storm water lines do not run anywhere. Part of the storm water system is asbestos.
• Project consultants are:
o Project Manager: Architects 44 Limited
o Lead Designer: Architects 44 Limited
2.2 Required solution (method and approach)
a. The Contract Works required are:
i. The sewer needs to be rerouted in three different directions from Block A to Block V and from Block A in two separate lines out to a common connection at Lucknow Street. Two manholes need to have concrete bases installed (currently just earth) as part of this work.
ii. The stormwater drainage needs to be replaced and regraded to avoid flooding the courtyard between Blocks A and B. The connection to the sanitary sewer system needs to be eliminated, and the currently unconnected pipe runs need to be extended to connect to the WDC storm sewer system. Asbestos piping needs to be removed and replaced.
iii. The Contractor will be engaged through a Medium Works Contract. No Contract related tags will be considered. The Principal prefers there to be no drawings and specification related Tags.
iv. See Tender Documents for further information.
b. Timeframes are:
i. Indicative Start date: 28/08/20
ii. Indicative Due Date for Completion: 08/01/21
