2022 looks like being an extremely busy one for PMG. We have recently signed a contract with Climate Change and Development Authority (CCDA) PNG, delivered through ADB (Asian Development Bank) funding, to build the Alotau Provincial Wharf in the Milne Bay province, approximately 300km south of Port Moresby, Papua New Guinea's capital city.
The project involves construction of an 80m long x 8m wide L shaped concrete wharf, founded on 38 off 711mm diameter x 16mm (or 20mm) wall thickness driven steel piles. Precast headstocks and decking units will be used, which will be cast by subcontractors in Alotau, with a cast in situ topping slab installed on site. In addition to the main wharf, the project involves demolition of an existing wharf structure, and installation of a 24m x 4m low level wharf (floating concrete pontoon), restrained by an additional 9 piles. The pontoon is accessed by aluminium gangways / landing platforms.
Some key project details:
- There is about 4 to 5 months lead up work required before mobilising to site around June 22, 2022.
- Key lead up work will include the order and preparation of the steel piles for the jetty, pre casting of concrete components in Alotau and the fabrication of the pontoon modules.
- PMG will be on site for about 5 months.
- The main equipment utilised will be a tug and 2 crane barges (180ft and 150ft) complete with piling frames and vibro and impact hammers.
- The first job, on arriving on site will be the demolition an existing wharf structure.
- Following demolition, the 38 wharf steel piles will be driven to support the wharf structure, and 9 steel piles to restrain the floating pontoon. These piles range from 37 up to 51 meters long and will be driven by a hammer operated off a 180T crane.
- The pre-cast concrete modules will then be utilised to construct the balance of the wharf and various fixtures then attached.
- The pontoon will then be installed including gangway and ramp.
- Landside and civil works including pavements, fencing etc will be undertaken throughout the project.
