Kanimbla Heights Estate, Stage 24B, Cairns QLD


ERSCON have closely worked with FGF Developments to ensure the

challenges presented by this site have been effectively addressed.

The resolution of water management issues, the excavation of rock

out crops and slope stability issues have been resolved using honest

communication, engineering experience and practical knowledge.

Paga Hill Devleopment, Papua New Guina

The Paga Hill Estate is located on a small peninsula adjacent to the Port Moresby CBD and is considered to be the future of PNG. The total developable land area covers an area of approximately 28 ha with a 2ha (approx.) elevated summit at 90m above sea level.

With spectacular views, idyllic surrounds, historic war relics and located less than a ten-minute walk to the Port Moresby downtown area, the site provides an unparalleled opportunity to develop a master planned, exclusive development consisting of hotels, resorts, executive residential, technology, commercial, marina and open space precincts.

“With such an opportunity comes responsibility, and despite an enduring timeline, we’ve remained true to our vision of a comprehensively planned, landmark and inclusive development that will transform the face of Port Moresby.” “The site will be one for all to enjoy, a vibrant hub and focal point for the city, and more importantly, an icon of a modern and progressive PNG.”


ERSCON has been working with Paga Hill Development Company (PHDC) for over 10 years and have provided ongoing Civil Design and Contract Administration assistance for the development of the site. The first stage of land reclamation work is currently underway that will create a 9hectare waterfront site for mixed use private and public developments. The seaward edge of the site will include a 700m long waterfront promenade that will be open for public use. Reclamation works are scheduled to be completed in 2023 and ERSCON is now working with PHDC in preparing design options to continue the reclamation works in future stages around Paga Hill.


Paga Hill Estate holds Physical Planning Board approval for bulk earthworks on the site (including reclamation of the sea lease area), preliminary building approval for the complete development of the site including building mass, road networks and intersection locations with the Paga Hill Ring Road. The site has recently been recognised as a Project of National Significance and has received a 99 years exclusive casino licence.   

Normanton Boat Ramp, Normanton QLD

Normanton Boat Ramp upgrade and pontoon installation, was a project aimed at enhancing the functionality and accessibility of the existing boat ramp located in Normanton, a coastal town known for its boating and fishing activities. The project involves various upgrades and enhancements to improve the overall user experience and safety for boaters and anglers. The Normanton Boat Ramp Improvements included design review, procurement, administration and on-site construction support.

The improvements may include expanding the boat ramp to accommodate larger vessels, improving the ramp surface and traction, and enhancing the surrounding infrastructure such as parking areas, lighting, and signage. Additionally, efforts may be made to optimize the boat ramp's alignment and slope, ensuring ease of launching and retrieving boats.

By enhancing the Normanton Boat Ramp, the project aims to alleviate congestion during peak periods, reduce waiting times, and improve overall efficiency for boaters. These improvements are expected to enhance the recreational boating and fishing experience, promoting tourism and economic growth in the local community.


Karumba Seawall, Karumba QLD

The project was for the construction of a concrete seawall with rock armoured toe. The project was constrained by the natural habitat, in that extreme care was required to reduce the impact on the mangroves and local environment and negotiate marine plant offsets where this could not be avoided.


This project was particularly challenging as there were significant latent conditions with significant voids and additional instability identified throughout the construction phase as the old concrete was removed for replacement.


This required tight scope and cost management to ensure the project was delivered within the allocated budget.

Shoal Point Development, Mackay QLD

ERSCON worked closely with the Developer and local authorities on the ongoing Shoal Point Development that includes 299 residential lots, 3 high density lots, a shopping village, and a resort site. Our company is committed to delivering quality work that meets our clients’ needs and can provide engineering support across multiple project aspects to ensure successful delivery.

Our involvement in the project has been extensive, spanning from initial feasibility estimates to detailed civil design, contract administration, and construction supervision. Major works include:

  • Design of Bulk earthworks across the site, approximately 200,000m3 cut to fill.

  • Detail design of all civil infrastructure on the first 3 stages (100 residential lots).

  • Superintendent role and construction inspections of bulk earthworks, first 2 stages of civil works (67 residential lots) and the entry road.

Additionally, we offer more detailed consulting services, which were particularly relevant for this project. We collaborated with multiple subconsultants to provide the following services:

  • Water Sensitive Urban Design (WSUD) Modelling using MUSIC.

  • WSUD design and supervision of bioretention basin construction.

  • Trunk sewer hydraulic modelling.

  • Trunk sewer infrastructure construction supervision (sewer pump stations and rising mains)

  • Contaminated land coordination to remove the site from the Environmental Management Register.

  • Rock Revetment design.

  • Coordination of coastal engineering erosion assessments and monitoring.

  • Coordination of blasting for bulk earthworks.

  • Cultural heritage liaison to gain approvals to clear the site.
