Basements, the deeper the better, are the passion of the owners of L&D Contracting and each Keith takes great pride in the number of basements that he has personally delivered. Between the Keiths, the Company has delivered over one hundred and twenty (120) major basement excavations in Brisbane, as either excavation only or complete early works packages. The reputation of the Keiths is unsurpassable.
Delivering basement excavations within a city precinct takes great planning and coordination and L&D Contracting have the runs on the board when it comes to mitigating noise and vibration, managing traffic and pedestrians, controlling erosion and sediment and coordinating truck movements with city peak traffic and buses.
Depending on location, basements are built in the hardest of rock or the softest of clay or combination of both. Regardless of the ground conditions, we have the right plant to suit the job; large and small excavators fitted with buckets, rippers and breakers, dozers, drotts and bobcats; and not forgetting the most important item which is our very experienced supervisors of whom we are very proud.
L&D Contracting have proven experience excavating to depths of thirty-eight (38) metres for Clem 7 cross-river road tunnel access shafts and numerous basements to twenty-five (25) metres including the Treasury Casino, Queens Plaza and McArthur Chambers in Queen Street, Brisbane. Excavating to depth requires special techniques and expertise and in addition to our breakers, saws and road-headers we have successfully deployed low vibration controlled blasting on numerous occasions. Also, removing spoil from the excavation must not be overlooked and we have a variety of applications to do this including ramping, mechanical spoil lifter and long-reach excavators mounted on platforms. The company has also delivered numerous basements with ‘Top-Down’ methodology.
Although we have undertaken a lot of dig only basements, more often we are asked by the client to provide a complete package including demolition, shoring and retention for which we engage the specialist subcontractors directly.
