Cleary Bros has provided construction services to many well recognised clients in private industry. Current projects can be found here. Some of our valued clients include:

Delfin Lend Lease

Wilton Estate

Cleary Bros suggested to Delfin Lend Lease that the excavated material be re-processed on site to manufacture sub base pavement material to mitigate the cost of importing off site material. The client advised that they wish to pursue our idea and that this will be undertaken in the future, dependant on demand for house lot sales.

Baulderstone Hornibrook

Mascot Airport Parallel Runway

Our client, Baulderstone Hornibrook (BH) advised that the client nominated and supplied a 100 tonne roller to proof roll the fills. Historically this 100 tonne roller has been towed by two coupled D9 dozers (you can imagine how time consuming coupling & decoupling 2 x D9 dozers in low ground bearing pressure conditions would be). Cleary Bros proposed that 1 x 720 horsepower D10 could be utilised to do the same job. Our client implemented the D10 and this increased the mobility of the plant and decreased the time to complete the proof rolls. The client representative would witness and release each proof roll as a lot. The revised work method suggested by Cleary Bros improved the speed in which lots were released by the client and consequently resulted in both time and cost savings to BH as this activity was on the critical path.

Transfield Bouygues

Airport Rail Link Tunnel

For this Rail Project, we designed and constructed a 30m drop structure to load the underground trucks. The structure was required to ensure that no segregation occurred when material was dropped from height. Cleary Bros complied with this requirement as well as designing the structure to store a minimum of 30 tonne of material to eliminate any waiting time for the underground trucks when loading. In addition, we designed and constructed a loading platform to lower the modified trucks down the shaft and into the rail tunnel.

However, our most innovative solution for this project was the one that allowed Transfield Bouygues to complete the project some 6 months in advance (and therefore make significant savings in overheads), the truck that Cleary Bros fully modified to enable forward and reverse speeds of 60km/hr with driver aided rear camera vision and offset cabin.

Cleary Bros also specially modified a spreader attachment to a D6 enabling the unloading of trucks and trimming of the rail formation to a uniform thickness in one continuous operation. In addition, the Rail Authority required deflection testing post installation of the rail track. CB proposed an idea to our client that we could calculate the effect of the rail mass and the ballast and then proof roll the rail formation prior to the installation of the rail and ballast to eliminate any risk of deconstructing the rail or ballast during the deflection testing. This idea was successfully implemented by our client.

The cllient required that the material in the rail formation was tested as it was being placed. Cleary Bros suggested to our client that we test & certify stockpiles prior to hauling & placing the material into the rail tunnel. This proposal was accepted by our client which allowed the stockpiles to be located adjacent our pug mill on site and allowed fresh batches to be manufactured as required prior to placement in the drop structure. This was a significant time saving innovation to our client.
