1856-Construction Management Plan (Prelim V2) Oct 2020 - Barlow Shelley · OPW20/0145

ESC strategy must be prepared and updated by the Contractor to reflect the actual
progress of the works and site-specific constraints.

Notwithstanding the above, it is the ultimate responsibility of the Contractor to ensure that
adequate erosion and sediment controls are implemented at the site to ensure any water
released from the site meets the water quality objective of TSS (Total Suspended Solids)
= 50mg/L.


The erosion and sediment control measures are to be maintained by the Contractor during
the maintenance period or until the site is established with 70-80% ground cover.

Erosion and sediment control measures should include, but not be limited to the following:
  ·   Diversion of clean water away from the work areas
  ·   Entry/ Exit Sediment Trap as per IPWEAQ D-0040
  ·   Capture & treatment of dirty water (incl. groundwater) in a bunded area or basin
  ·   Provision of silt fences as a ‘last line of defense’ downstream of all work areas
  ·   Minimising of disturbed areas
  ·   Stabilisation of batters and exposed areas immediately upon completion of
      earthworks
  ·   Installation of additional measures as required prior to anticipated rainfall
  ·   Ongoing maintenance of the control systems
  ·   Inspection and maintenance of control systems after rainfall events


Should any services require relocation as part of the works, this shall be carried out by an
approved contractor for each relevant asset owner.

4.8    Protection of Existing Infrastructure

All existing infrastructure, e.g. road pavement, drainage pipes, conduits, etc. is to be
protected and maintained during the construction period. Any damage caused by the
Contractor is to be rectified at the Contractor’s expense.          It is recommended that
photographic evidence of the site and surrounds be collected prior to the commencement
of works.

It is the Contractor’s responsibility to locate all existing services prior to commencement of
works and protect and maintain these services for the duration of the works.
