Amharc’s project management and field staff have been involved with the delivery of a number of highly successful civil infrastructure projects including;
CASE STUDY 1:
Burnett River Bridge, QLD

Initially engaged on a lump sum contract to construct 4 new concrete baffle walls, Amharc successfully secured additional works on the project following the successful execution of the originally contracted works. These additional works included concrete skylight, stopboard and weir FRP infills and construction of a new flowmeter pit. Amharc also provided labour hire services on Oxley STP providing pipelayers, labourers, formworkers, steelfixers and concreters. During their time on site Amharc personnel showed a continued commitment to improving safety and carried out their works to a high standard of quality evidenced by the fact that no NCR’s were issued throughout our 9 months on site.
CASE STUDY 3:
Warrego Highway Upgrade, Charlton, QLD
Amharc was contracted by Georgiou Group to deliver a two span bridge across the Warrego Highway at Kingsthorpe along with baseslabs, apron slabs and headwalls/wingwalls for 54 culverts and gas protection works for an existing gas main running through the site. These works were carried out to a strict programme to enable the clients traffic switches to happen as planned. The project commenced in April 2017 and was completed within 10 months having a peak workforce of 18 men.

The works needed to be carried out to a tight timeline within an active Wastewater Treatment plant without any disruptions to the plant operations. A mechanically anchored polyethylene liner was cast into the internal face of all structures to prevent concrete degradation ordinarily caused by hydrogen sulphide in the wastewater.

The project was logistically complex and site restraints led to extremely tight work fronts with limited working room and a high degree of pedestrian/cyclist/vehicle traffic around the work site. Amharc maintained a strong commitment to safety, and their expertise and efforts in completion of the package of works was a key component to the overall successful completion of the Stage 1A project on time. Amharc’s performance on the Stage 1A works led to the award of the subsequent concrete package of works for Stage 1B
