PLATE BEARING TEST SERVICE

It is routinely used in the design of temporary structures such as working platforms for piling rigs or pads for crane outriggers. 
Approximate equivalent CBR values can be derived from the Modulus of subgrade reaction by the use of empirical relationships.
The Plate Bearing Test is carried out in accordance with BS 1377 Part 9: 1990 and consists of loading a steel plate and recording the settlement corresponding to each load increment.
The Plate Bearing Test is normally carried out at the foundation level, either on the surface or in a shallow pit. Plates of varying sizes up to 720mm diameter are available. The loading plate is placed on the ground and connected via a load cell to a reaction load. Due to the larger size of the plate used (compared with a CBR test), this test is more suitable for testing larger aggregate backfills, however, it requires a larger reaction load. Typically, a minimum 15tonne tracked excavator or another suitable plant is required for us to use as a reaction load.
Our engineers will advise on the plate size required to match the design load and reaction load required (i.e. size of the excavator).
We can typically complete six tests in a day, subject to site conditions and can provide results the following day.

Site Investigation

Site investigation is a procedure guided by strong and well-defined security practices, with site-specific objective statements and risk assessments provided. A site investigation is the initial stage in establishing an on-site investigation service. Subsurface site investigations are essential to the site's Geo-Environmental status report. It addresses any landfill/gas issue. Earth Environmental has extensive experience in geotechnical, mining, and environmental site inspections.  Visit  https://www.earthenvironmental.co.uk/site-investigation/ to learn more about our services and procedures.  https://www.earthenvironmental.co.uk/conducting-site-investigations/

Flood Risk Assessment

The term " flood risk assessment " (FRA) refers to a process that identifies the potential causes, severity, and necessary mitigation measures for floods. Flood zones 1–3 defined the strategic flood risk assessment. The scope and parameters of the flood risk assessment will depend on the development site's area and terrain. Flood Risk Assessments are conducted for a variety of places in order to meet local planning requirements and to follow the advice and guidance of the Environment Agency and the National Planning Policy Framework.

Phase 1 Desk Study

A phase 1 desk study 's primary purpose is to detect possible dangers and a lack of safety measures on the construction site. The Phase 1 desk study yields a comprehensive report which details every aspect of the research process. Each phase 1 desk research report includes a walkover survey of the site. Site examination built with existing data on the site's ecology, geology, hydrogeology, and mining frameworks.  To learn more, visit  http s://www.earthenvironmental.co.uk/phase-1-desk-study/ .
