December 2010 - July 2011
 
Barangaroo Delivery Authority - Barangaroo at Sydney
 
The works will involve drilling 31 boreholes on the northern end of the site, 18 boreholes on Hickson Road, and the material extracted will be sampled and tested. 18 test pits will also be excavated with soil removed from the test pits temporarily stockpiled next to the pit. These works are in preparation for sewer works to occur on site and on Hickson Road.
 
The sewer works involve the construction of temporary sewerage bypass, diversion of existing sewer lines, and diversion of existing stormwater services. Breakdown of works are as follows: 
  • Works will commence with the excavation and concrete encasement of the existing DN450mm stormwater line approximately 55 metres long, followed by the excavation and concrete encasement of the second existing DN450mm stormwater line approximately 58 metres long.
  • Following on from this we will excavate, lay backfill with excavated material, test, and commission a new DN450mm stormwater line approximetaly 132 metres in length, including the building of manholes and interconnection with exisiting stormwater lines. Stormwater lines that are no longer required will be sealed.
  • Dismantle the exisiting SPC compound fence and carport.
  • Excavate around and concrete encase the existing SWC 225mm diameter sewer rising main which is approximately 80 metre in length.
  • Excavate for and construct a reinforced concrete slab over the existing SWC 400mm diameter overflow sewer from SPS 0014. This will be 6 metres wide by approximately 60 metres in length and will be laid to finish flush with the existing ground level.
  • Location and interception of the existing SWC 300mm sewer at Hickson Road where we will construct a manhole. A manhole will also be constructed in the access drive with interconnecting pipework and the area will be backfilled and reinstated.
  • Interception of the existing 150mm diameter sewer outside the SPC fence line and we will excavate, lay backfill with excavated material, test, and commission a new DN150mm sewer line approximately 280 metres in length, including the installation of the manholes along the route to the new SPS.
  • Excavation and installation of the SPS sewer pumping system including the wet well, mechanical equipment, pumps ect., including the electric cabling to adjacent switchboard. These works will involve dewatering of shaft excavation.
  • Installation of DN150mm sewer rising main from new SPS to existing SPS 1120. The works will involve the installation of pipework both underground, where there are to be entrances constructed, and above ground. The above ground pipework is to be attached to existing concrete plinth along the existing fence line.
Other services Killard Excavation Pty Ltd will provide include traffic management and the supply, installation, and relocation of temporary safety fencing where required.

The smaller pipes were laid within the site, including 115 metres running at the top of a 35 metre sheer vertical wall which required stringent safety standards to install. Access / egress plans and material handling proceedures were devised with the client and implemented sucessfully. A 25 metre section of 375mm welded PE pipe was hung from an internal carpark ceiling 4.5 metres above floor level using scissor lifts. This pipe section was not linear and bends were manufactured on site and cradles designed and bolted to the ceiling to support pipework.

May 2008 - October 2008
 
BCC Networks Alliance - Heathcote National Park
 
The existing DN450 DICL main in Heathcote National Park was found to have deteriorated due to sewer gas retention within the main. The pipeline had to be kept online for the replacement process. A 200 metre PE bypass main was constructed and cut in under pump station shutdowns, which diverted flow for the process of exhume and relay to occur.
 
The DICL pipe was replaced with PVC pipe. 4060 metres of pipeline was upgraded. A corridor was cleared and works undertaken, and then stringent bush regeneration and management was implemented.
 
Killard Excavation Pty Ltd employees were trained to an asset isolation plan (which was developed by Killard Excavation) and shut down two pump stations for each bypass transfer.
 
Scope of works included:
  • Set-up of 200 meter by-pass PE piping arrangement to facilitate exhume and lay
  • Exhume existing 450mm DICL sewer main and lay approximately 2700 meters of DN450 mPVC / DN600 GRP PN 16 sewer rising main and install valves and other associated structures
  • Remove existing air / scour valves
  • Connect SPS 589 to newly lain SRM
  • Remove existing DN300 vent stack and install a new vent shaft including DN150 uPUV vent line from air valve chamber to vent shack
June 2008
 
BCV Networks Alliance - Heathcote
 
The works involved the shutdown of pump units to enable the connection of sewer by the Heathcote Sewer Project. This entailed undertaking the exhumation and relaying of existing DICL sewermain due to severe corrosion by acids contained in sewerage. This required shutting down pump stations initially and installing a 200 metre length bypass connection to facilitate the works. Once one section of the pipe was exhumed and re-laid as PVC the pump stations were shut down and the bypass moved to the next section.
 
The shut down of pump units required the creation and implementation of an asset isolation plan, which included the creation of a flow management plan. The asset isolation / flow management plan encompassed a contingency plan to handle any possible risks to the successful completion of works, and a hazard / risk management plan to ensure the safety of employees, the environment, and customers during works.
