Yan Yean Conduits & Concrete Package

D Form Civil were engaged for the structural works for the new TX yard in Yan Yean Pump station along with the install of the conduits for the site. These works were part of an upgrade to the Water treatment plant with the construction of a new pump station. 

Our team were commissioned to complete the structural scope of constructing new Transformer, Auxiliary Transformer and Capacitor Bank Footings and all of the earthworks required. Additionally to this there was the installation of the associated conduit network including precast concrete pits, and over 1200m of electrical conduit. Over the course of the project D Form was tasked with completing additional works including installation of PVC and Ductile Iron drainage systems, additional footings, bollards and footpaths. 

Works were completed on time despite the challenges faced as there were other civil contractors on site completing separate scopes of works. This created the need to implement change management to our schedule to ensure continuity of our own teams works.

Hastings Zone Substation

D form Civil were engaged by BEON as part of the a series of upgrades to the existing United Energy Zone Substation in Hastings. The station upgrades included the addition of a 66kV feed to the nearby Esso Terminal and the replacement of the existing Control Room. 

D Form Civil completed the extension of the existing 66kV & 22kV Switchyards, construction of approx. 30 foundations, installation of new conduits and pulling pits, stormwater drainage and final surfacing. Upon completion of the new Control Room installation works, the existing Control Room was demolished which involved the removal of and disposal of existing asbestos cladding.

Richmond Terminal Station

D Form Civil were engaged by Multiworks to complete the formwork package of the 220kV Cable Culvert at the Richmond Terminal Station Upgrade project. Being our first contract works within the live electrical substation sector, this project was key to prove the capabilities of our teams within these High-Risk work environments. The first package included forming approx. 50lm of 2m high walls which would eventually house connecting 220kV Cables from the GIS Building to a Transformer.

Upon successful completion of the 220kV Culvert, D Form Civil were then engaged to form the basement walls, columns, and suspended slab for the 66kV GIS Building within the station. The building was on the critical path for the client, and as such the works needed to be well planned to ensure that the timeframes were met. Through consultation with the client, the methodology was revised which allowed 75lm of 3.2m high walls to be formed and poured within 5 days. This allowed the remaining works to be completed ahead of schedule.
