APPROVED Document - Concept Construction Management Plan · OPW11/0116

2. INTENT OF CONCEPT CONSTRUCTION MANAGEMENT PLAN

This Concept Construction Management Plan is intended to provide an indication of how works may be undertaken by the
contractor, likely environmental impacts and intended control measures.

The contractor is to prepare a final construction management plan prior to commencing works and a copy is to be provided to
DERM. The contractor's methodology, plant, equipment, scheduling etc may vary from that indicated here. Any changes to

the intended methodology that may increase the impact of the works is not to be implemented without further discussion with

DERM.

3. DESCRIPTION AND PURPOSE OF WORKS

With the exception of those areas already protected by rock works, Noosa River Spit is currently experiencing erosion along
its full length, including the southern end of the Noosa River Spit. While this is reducing amenity along what was once a
popular recreational beach, there is also the potential for continued erosion to breach the Noosa River Spit, which could have
very serious impacts.

A number of options were considered [ICM 2010 report}. The preferred option includes [Figure 3}:
e Submerged curved “closure” [sand-filled geotextile mega-containers] designed to create an enclosed, stable
beach and lagoon area
Dredging for interim navigation and associated foreshore nourishment
Training wall [sand-filled geotextile mega-containers] to provide a control point for the southern channel
Wall [sand-filled geotextile mega-containers] to prevent erosion along southern end of the Noosa River Spit
Two groynes [2.5m3 sand-filled geotextile containers] to stabilize the upstream beach
