ProjectRiverhills Public Pontoon

Structural, Civil and Environmental Engineering blend together in the design of this maritime project

In a joint venture with Envirostruct Services, APP provided the structural, civil, and environmental engineering, reporting and management for this maritime project.

The design includes the installation of a floating platform (approximately 16m x 6m plan dimensions) held in place by a system of four driven piles. The design also includes placement of armour rock on the approach embankment batters around the abutment for scour protection during flood events.

The pontoon structure is located on the internal bend of the Brisbane River, adjacent Newcomb Park, Riverhills and is located downstream of the existing pontoon.

Reducing our Power Consumption

Our office is looking super good! We have replaced the old style Fluro light panels within our office to the new energy efficient LED light panels. The swap over will generate a huge reduction in our energy consumption, lower our environmental impact and reduce the need for maintenance, as LED lights have a 5 year life expectancy. We now have a much brighter office and are only consuming a third of the power we once used. The change over is part of the NSW Government initiative for businesses to reduce power usage.

ProjectBallina & Alstonville Aquatic Facilities

Both pools incorporate a wet edge design to maintain the water level just below the surrounding concourse level, and the state of the art heating pumps are powered by the sun.

The Brief:

Ardill Payne & Partners (APP) was engaged by Woollam Constructions to undertake structural design and documentation for the pool upgrades at Ballina and Alstonville. Works for Ballina involved demolition of existing amenities building and pool, construction of new amenities building, café, pump/filter, storage rooms, new heats 25m Learn to Swim pool, 8 lane FINA compliant 50m pool, covered roof for 25m Learn to Swim pool, pool concourses and landscaped areas. Works for Alstonville involved construction of club house, pump/filter, storage rooms, new heats 25m Learn to Swim pool, 8 lane FINA compliant 50m pool, covered roof for 25m Learn to Swim pool and pool concourses and landscaped areas.

Key Challenges:

The key challenges were that the new pools incorporate a wet edge design to maintain the water level just below the surrounding concourse level, this aspect of the pool designs weighed heavily on structures and concourse designs. The challenges were to control total and differential settlement to be within very tight tolerances, the concourse areas surrounding need to shed storm runoff away from the pool whilst maintaining compliant gradients, and to ensure minimal interaction between the building and the pools to prevent unintended damage to either structure.


The solutions involved detailed review of geotechnical information, investigation of various piling options to refine differential settlements, so that cost effective foundation solutions could be determined and performance criteria met. The new building and covered roofs were isolated from the pool structures where possible and designed to reduce loadings to the pool shells. Concourse slab design and construction was completed in a manner to allow for differential movements and shrinkage of the two elements.

Key Features:

The 50 meter pools are heated and have eight 2.5m wide lanes and the 25m heated enclosed pools have six lanes. There are access ramps into all pools, a wet play splash area for children, covered tiered seating and brand new BBQ facilities and shelters. The Ballina site received a new amenities building and café with an outdoor seating area, and transparent fencing along the Richmond River. The Alstonville site received a new club house.

APP's Role:

APP undertook the Structural design and documentation, set out Survey, Civil design and documentation for site grading’s, concrete pathway layouts and details, certification of works, site inspections of both structures designed by APP and the new pools and RFIs. Detailed pool design for reinforcing and concrete design was completed by Crystal Pools.


The project was completed within the timeframe Feb 2017 to July 2018.


The budget for both projects was approximately $14,000,000.

Key Parties:

  • Woollam Constructions
  • Crystal Pools
  • Dave Bazar Plumbing
  • Glen Monteith Hydraulic Consultant
  • Bond and Associates Chartered Architect
