Project Type: Wastewater
Faced with multiple challenges around wastewater management on a site that is subject to extreme weather events, the client implemented a wide ranging project which would both benefit the local community through providing cleaner waterways and allow it to operate cost effectively and in an environmentally responsible manner going forward.
Techo delivered two aspects of the overarching project:
1. Identifying and implementing improvements to contain and manage wastewater on the factory site (details on this project will be added at a later date)
2. The addition of 8,000,000 litres of off-site wastewater storage capacity, including the construction of a new irrigation plant and all associated tie-ins with new and existing infrastructure.
The off-site project consisted of two sites. The larger of the two sites included the construction of 3 x 2700m3 mild steel storage tanks and integrating them into the wastewater stream from the factory. Erecting 2 x 200m3 stainless steel silos and tying both the tanks and the silos into the existing irrigation network. A new MCC building was also built. This site was a combination of a greenfield site (the area for the tank pad for the three large tanks, new MCC building and some additional site works) and a brownfield site (addition of two new silos and the associated pad into the existing irrigation plant and the new mechanical and electrical infrastructure to tie everything in).
The second site was a greenfield site and involved constructing a new wastewater irrigation plant from the ground up. This included constructing 2 x 400m3 stainless steel tanks, the tank pad, a new MCC building and miscellaneous civil works.
Techo managed all civil, mechanical and electrical works on both sites, along with the construction of the two new MCC buildings.
Two additional main contractors carried out other aspects of the clients’ overarching project. The nature of our project meant that Techo had to work closely with one of them to co-ordinate planning, avoid conflicts or miscommunication and achieve the required outcome.
A number of challenges arose during the course of the project. This included complicated geotechnical issues, frequent and extended periods of heavy rainfall and an extreme flooding event which had a devastating effect on the local community (as shown in the last two photos in the slide-show). Techo staff were involved in rescuing people from flooded houses and manning pumps to help farmers clear their land of flood water in the days that followed.
Techo is proud to have been part of a project that will benefit the local community for many years to come and which was recognised by the client as having set the benchmark for Health & Safety management and worker buy-in.
Project Value: $15 Million (Techo’s portion of the project)
Duration: 12 Months
Project Type: Turn-key, managed under Techo’s Safe Work System
Project Man Hours: 44,000 (including Civil Works)
Successful delivery of a project in the face of several unexpected and significant challenges
