How much does it cost?
EarthBolt NSW quotes a fixed amount per anchor for the installation and removal which includes 2 site visits. The price per unit is based on a sliding scale for the number of anchors required on the project.
What depth is an EarthBolt NSW installed to?
An EarthBolt NSW anchor is screwed into the ground to a depth of 1350mm and electronically monitored for torque level to ascertain its kN loading. The EarthBolt NSW safety anchor has been tested for load applications with a prop connection at 60 degrees to a WLL of 52kN and used for panels of up to 12.4 metres in height.
What do we need for a formal quotation?
EarthBolt NSW requires the precast or tilt panel manufacturers Panel or Bracing Layout, including Panel Elevations to generate a quotation. All files in PDF Format.
How long does it take to install/remove?
Depending on site induction time and ground conditions, the EarthBolt NSW operations team will install enough safety anchors for 50 precast concrete panels per day. A maximum of 100 in a single day can be achieved with good conditions. Generally it takes half the time on site to remove the same number of anchors.
What if the ground is not suitable?
EarthBolt NSW require a geotechnical report and combined with our experience of different localities we can assess the suitability of EarthBolts for a project.
In difficult areas we make every effort to ensure installation with earlier site testing or pre-drilling pilot holes with a mining spec auger.
What equipment is used in the process?
EarthBolt NSW uses current model 5.5t excavators with a customised planetary drive unit putting out over 18,000 Nm of torque to install and remove our product. Product is loaded and unloaded in stillage units via a current model skid steer or tracked loader and distributed around the project site as required. All machines are serviced regularly in accordance with the manufacturer’s guidelines by their Australian distributor.
Do mezzanine level offices and basement structures cause height issues during removal?
Generally no it is not an issue as removals can be done with our skid steer equipment so even access heights down to 2.2 metres are acceptable.
How long can we have them on site?
Our quotations allow the product to be installed on site for 28 days, after which the company charges a daily hire rate.
What bolts are required to connect brace or prop footings to an EarthBolt NSW?
We supply flanged M20 bolts for the lifting process.
What about underground services?
Before EarthBolt NSW staff commence any installation during the site investigation it is the Site Managers responsibility to clearly mark any existing services to ensure no damage occurs. This has always delivered a problem free installation over the years.
What if the ground close to an anchor is disturbed?
If an anchor is subjected to additional earthworks i.e. trenching within 1500mm or major storm erosion EarthBolt NSW must be notified immediately for our Engineers opinion.
How much lead time do we need to give EarthBolt NSW?
We recommend giving us at least 5 days notice prior to the installation or removal of EarthBolts. We always endeavour to get their earlier – but will be in contact prior to arrival.
We will always try our best, our aim is to under promise and over deliver.
Does Rain Effect the EarthBolts?
All the sites where we install EarthBolts are already levelled and compacted in preparation for the construction of the building. The ground is solid and remains the same even with rain. There has never been a problem with this in Melbourne where they have installed over 300,000 EarthBolts in the last 10 years.
Has an EarthBolt propping anchor ever failed?
No. The EarthBolt system comes from Victoria where there has been over 300,000 EarthBolts installed in ten years without any failures.
