Trial pit excavation

Priority Geotechnical Ltd. undertake trial pit excavations to determine the soil profile and allow for the bulk sampling of soils for testing. Both track mounted excavators and JCB are used to access a variety of ground conditions allowing for trial pit excavations. Priority Geotechnical will assess the terrain and our Client requirements and use the appropriate plant for the works.

A suitably experienced Engineering Geologist or Geotechnical Engineer is at all time present to log the soil encountered in accordance with BS5930: 1999 and take a photographic record of the excavation and excavated material. Groundwater will be monitored when encountered. Trial pits can be excavated using double lift technique to allow for excavations up to 7.0m deep to be undertaken, if required. All sampling requirements are such to meet our Client requirements. Detailed geotechnical logs are prepared using AGS compatible software. Priority Geotechnical can prepare soil test schedules and will undertake soil testing to determine the soil engineering characteristics required for engineering design to our Clients needs.

Priority Geotechnical can undertake in-situ infiltration tests, California Bearing Ratio Test and Plate Bearing Tests during trial pit excavation to further assess the ground and obtain engineering design parameters

Priority Geotechnical Ltd. can provide interpretive reporting on the ground conditions encountered, the soil characteristics and engineering properties where required by our Clients.

Upon completion of cable percussive an experience Engineering Geologist or Geotechnical Engineer will prepare detailed geotechnical logs using AGS compatible software.

All fieldworks are carried out in accordance with the relevant British Standards: BS 5930.

Trial rock excavation

Priority Geotechnical Ltd. undertake trial rock excavations to determine the potential rate of excavation through rock where encountered. Track mounted excavators and hydraulic breaking equipment are used to excavated the rock mass. A suitably experienced Engineering Geologist or Geotechnical Engineer will measure the rate of excavation and subsequently log and record the rock mass structure. Priority Geotechnical will prepare rock test schedules and can undertake rock testing to determine the engineering characteristics of the rock mass and excavated rock required for engineering design to our Clients needs.

Priority Geotechnical can provide interpretive reporting on the rock mass characteristics and engineering properties of the excavated rock material for potential re-use as an engineering material or quarried material where required. Additional non-intrusive investigation and rotary drilling may be recommended depending on the nature of our Clients requirements.


Slit Trench Excavation

Priority Geotechnical Ltd. undertake slit trench excavations to determine the soil profile and presence of underground services to a depth of typically 1.2m and allow for the bulk sampling of soils for testing.

A suitably experienced Engineering Geologist or Geotechnical Engineer is at all time present to log the soil present in accordance with BS5930: 1999 and record the location and depth of services encountered.

Due to the nature of slit trench excavation Priority Geotechnical take the up-most care in setting out traffic management and liaising with the service providers to ensure both minimum disruption to traffic and services. Temporary and Permanent Immediate Reinstatements are undertaken in accordance with the Clients and Local Authority requirements.

Details geotechnical logs are prepared and plans are provided in AutoCAD format identifying the location of services in plan and section at the location of the slit trench excavation.

Priority Geotechnical Ltd. will prepare soil test schedules and can undertake soil testing to determine the soil engineering characteristics required for engineering design to our Clients needs

Pavement Coring

Priority Geotechnical Ltd. undertake pavement coring (100m to 150mm) to determine the pavement profile and allow for sampling of pavement layers, surface, binder and base for specialist testing.

Pavement coring is required to determine the pavement profile for: overlay design, Falling Weight Deflectometer analysis and analytical pavement design.

A suitably experienced Engineer will log the pavement core determining the binder, aggregate type and size and various pavement layers present. Detailed pavement core logs and photographic records are produced to allow for scheduling of specialist tests.

Due to the nature of pavement coring Priority Geotechnical take the upmost care in setting out traffic management and liaising with he service providers to ensure both minimum disruption to traffic and services. Permanent Immediate Reinstatements are undertaken in accordance with the Clients and Local Authority requirements once pavement cores have been extracted.
