Managing Complexity Without Compromise
Rooney Group were engaged directly by Timaru Oil Services Limited, to complete the civil drainage, concrete building infrastructure works of the new Timaru fuel depot located on reclaimed beach gravels adjacent to Prime Port Timaru.
The contract value was $7.8 million, with the contract starting in August 2018 and successfully delivered in full to programme in March 2020, just as the Covid-19 pandemic took hold. Subsequently there was some minor clean-up required after the successful hydro testing in April 2020.
After four months working as a sole contractor on-site, Rooney’s was then one of the three main contractors working cooperatively together within the congested site. The site was shared with mechanical and electrical contractors, with a combination total of up to 80 personnel on site. The contract ran extremely smoothly with Rooney’s maintaining a safe and productive working environment with an excellent health and safety record.
Our team’s ability to collaborate with other head contractors throughout the project was a key to the successful delivery of this contract. Within a busy and complex 16,000 m² site, our scope of works concluded two 3,500 m² fully impervious fuel containment compounds, comprising of concrete tilt slabs, a HDPE membrane, and an AP 40 base course layer. Construction of the five tank foundations were required to be within 3mm accuracy to ensure the steel fabrications could be assembled without modification. Rooney surveyors closely monitored the construction to exceed the expectations by one millimetre. Service infrastructure included power water, telecom, sewer reticulation and connections were all part of the contract.
Project Scope:
- 16,000 m2 site constructed to oil industry quality and safety standards
- Construction of two impervious cells for potential fuel containment
- 5 concrete fuel tank ring beams built to a tolerance of +-3mm accuracy
- All site underground service infrastructure.
Technical Information:
The site works undertaken was all constructed to Oil Industry guidelines including various pavement foundations for the steel tank and associated structures. Testing of all aspects of construction including waterproofness of structures was tightly managed.
Outcomes:
This project challenged the company’s adaptability to manage a range of critical subcontractor requirements so that they could achieve their own tight perimeters within a site that had very little room.
