Additional guidance concerning geosynthetic reinforced platforms is found in CIRIA SP123 - Soil reinforcement with geotextiles.
. There is a particular problem to be addressed and resolved. The Building Research Establishment BRE produced a practice guide for working platforms for tracked plant which has become a standard in the industry in the absence of any other widely. Good practice guide to the design installation maintenance and repair of ground-supported working platforms BR 470 written by Hilary Skinner.
The recently published BRE design method for calculating the thickness of the working platform for tracked plant eg. The Building Research Establishment BRE produced a practice guide for working platforms for tracked plant which has become a standard in the industry in the absence of any other widely published simple design method. The approach is based on a punching failure mechanism.
The Building Research Establishment BRE produced a. The designer should have full access to the health and safety plan including the desk study and all other site investigation information. All of the figures below are general examples.
Experience Calculation of the maximum track bearing pressures alone may give no indication of any impending instability due to the input loading. BRE 470 2004 provides design procedures on working platforms for tracked plants. The output from the BRE design method was subjected to a lengthy benchmarking process with a wide range of rig and crane types to ensure that with realistic input parameters safe but economical platform thicknesses would be produced.
Piling Platform Piling Mat Design Spreadsheet Description. A very helpful spreadsheet for designing working platforms for tracked plant piling platform for piling rig sheet piling righandler or other ground treatment machinery. The design of a working platform is a geotechnical design process and should be carried out by a competent person.
On 1 June 2004 BRE published Working platforms for tracked plant. Loading as the BRE design method imposes the design strength of the working platform. The BRE design method does not apply for thick platforms or for soft subgrades but continues to be used in those applications in the absence.
Out by a competent person. The calculation of the track bearing pressures in an appropriate manner consistent with the BRE design method is a fundamental requirement of its use and the use of bearing pressures calculated by any other means could potentially lead to. The calculation of the track bearing pressures in an appropriate manner consistent with the BRE design method is a fundamental requirement of its use.
Use of conservative parameters will result in the calculation of conservative and hence uneconomic. The BRE design method does not apply for thick platforms or for soft subgrades but continues to be used in those applications in the absence of an. BR 470 Working platforms for tracked plant1was published in 2004 and provides good practice guidance on the design installation maintenance and repair of ground supported working platforms constructed of granular material for the use of tracked plant.
Piling rigs and cranes requires the input of realistic parameters for the properties of both the platform material and the underlying stratum. April 2019 This TWF Guidance is available as a free download from wwwtwforum. Working Platform Design Spreadsheet to BRE Digest 470.
Previously there was no published or widely used simple design meth- od for these working platforms and. Without any check on rig stability for the required operating conditions the calculated maximum track. In the BRE design method are commonly much higher than given by a simple calculation of the total rig weight divided by the total track area.
Typically the method provides a working platform much thicker than commonly used successfully in Australian practice. WORKING PLATFORM DESIGN SENSITIVITY INTRODUCTION The recently published BRE design method for calculating the thickness of the working platform for tracked plant eg. The Building Research Establishment BRE produced a practice guide for working platforms for tracked plant which has become a standard in the industry in the absence of any other widely published simple design method.
The design of these geoetechnical structures is usually carried out in accordance with BRE 470 - Working platforms for tracked plant. Geosynthetic reinforced granular platform. Is a geotechnical design process and sh ould be carried.
More recently the Temporary Works Forum have published. The Building Research Establishment BRE in UK published a good practice guide to the design instal-lation maintenance and repair of ground-supported working platforms for tracked plant in 2004 with re-port reference BR 470 a term commonly used to refer to this guide also used in this paper. BRE design method are commonly much higher than given by a simple calculation of the total rig weight divided by the total track area.
In the BRE method no allowance is made for stress distribution with depth. Platform designs must be based on the. Piling rigs and cranes requires the input of realistic parameters for the properties of both the platform material and the underlying stratum.
How best to determine realistic and reliable design parameters in. For the purposes of this publication the expression working platform is restricted to ground-supported working platforms for tracked plant constructed of granular. The BRE design method for calculating the thickness of the working platform requires the use of realistic parameters for the properties of both the platform material and the underlying stratum.
A paper discussing the relationship between the platform thickness to the choice of parameters is available Working Platform Design Sensitivity.
