Principal Geotechnical Engineer – MD

Ross Nicolson BSc (Hons) MSc Eng CEng MIMMM

Principal Geotechnical EngineerOver 30 years experience in Site investigation, engineering geology and geotechnical and geo-environmental engineering both in the UK and in Africa. Main areas of interest – borehole investigations, desk studies, Site investigations, dams, tunnels, roads, slopes, pipelines, old mineworkings, foundation, building subsidence and contaminated land investigations.

Expert witness and geotechnical advisor to the South African Government for 2 years on the Hex River Tunnel arbitration providing advice on the foreseeability of the rock conditions encountered and the appropriateness of the tunnel support measures used. Spell as a senior lecturer in engineering geology and geo-environmental engineering at the University of Sunderland.

Some memorable jobs – Finding an elusive, untreated mine shaft in Workington after a gruelling 7 days demolishing a tower block basement. Instrumentation and monitoring of surcharging of peat at the former Head Wrightson Works, Stockton on Tees, where Margaret Thatcher took her walk in the wilderness. Preparing evidence for court and mentoring senior council for cross examination on one of the worlds largest tunnel disputes about unforeseen adverse rock conditions. Engineering geologist on the construction of 13 km Hex River Railway Tunnel by drill and blast. Lead engineering geologist for the Site investigation of the proposed 300m high Mbokazi Dam on the Umzimvubu River, South Africa. Borehole investigation identified previously unknown major ancient rock slides and fracture zones on the abutments and spillway of the main dam in a historically active earthquake area.

Established Nicolson Rock and Soil Drilling in 1992, BGP Site investigation and Contaminated Land Investigations in 1996, Geoinvestigate Limited Site investigation Specialists in 1997 and in 1997 the UK arm of mini-drilling and borehole equipment manufacturers Carl Hamm of Essen, Germany.

Senior Geo-environmental Engineer

Stuart Howe BSc., Hons., FGS.

Senior Geo-environmental EngineerOver 15 years’ experience in the design, costing and implementation of geo-environmental desk studies, Site investigations, ground investigations and contaminated land surveys across the UK.

Manager of Geoinvestigate’s North East office in Stokesley responsible for the day to day running of a busy, dynamic and expanding geo-consultancy. Personally involved in many hundreds of Building Subsidence Investigations, Site investigations, soil investigations and contaminated land investigations across the UK including London, Birmingham, Manchester, Leeds, Newcastle, the South East and Scotland.

Over the years have gained expertise in the use of various mini drilling techniques ranging from held window sampling, dynamic probing and various tracked mini drill rigs including the Dando Terrier and the MRZB. Have written numerous reports covering desk studies, Foundation design, Site investigation, building subsidence, mining subsidence, contaminated land, slope stability, landfill gas, contaminated land investigation and contaminated land remediation.

Memorable experiences include a foundation investigation for a new Monk’s Bridge at a priory in West Yorkshire involving the sinking of Boreholes over a large lake, the use of scaffold platforms and dinghy transport. Another was the borehole investigation and stabilisation of sinkholes/shakeholes which unexpectedly appeared in the cricket pitch, tennis courts and beneath the chemistry block of a school in Kirby Lonsdale near Ingleton, Yorkshire. A Trial pit investigation 10 years before had found voids but had not realised what they were.

Senior Geo-environmental Engineer

Jack Harper MSc Contaminated Land with Distinction

Contaminated Land ConsultantRead Natural Sciences at The College of St. Hild and St. Bede, Durham University. Originally from a background in fundamental chemistry and physics including environmental and computational chemistry I joined Geoinvestigate in 2006 as a geo-environmental chemist.

Over 6 years’ experience with Geoinvestigate designing, executing and reporting contaminated land Site investigations and contaminated land remediations. Building on a strong chemistry background my major role within the company has been to develop a specialist consultancy service to deal with the increasing complexity of contaminated land legislation and the ever more stringent requirements of the various statutory regulators including the Environment Agency and Local Authorities with regard to thorough and appropriate contaminated land investigation, risk assessment, remediation and validation.

As well as my ongoing interest in the research of contaminated land legislation and remediation methods my role at Geoinvestigate has been to ensure that the company adopts the most up-to-date practices and systems in this area. I have also strengthened my applied geological knowledge through the study of engineering geology, Geotechnics and soil science.

I have attained a high level of competency in the use of various drilling, probing and soil sampling techniques both for the recovery of geotechnical and Contaminated soil samples and to install gas and Groundwater monitoring wells. I have also gained expertise in the use of Environment Agency software and knowledge relating to their technical publications and guidance.

Memorable experiences include contaminated land Site investigations and site remediations in County Durham and West Yorkshire and studying part time at Newcastle University for an MSc Environmental Biogeochemistry with Consultancy Skills.

Fieldworks Manager

Anthony Montgomery

Fieldworks ManagerOver 8 years experience in the operation and maintenance of a range of Site investigation equipment including concrete corers, dynamic probes, hand held percussion window samplers and various tracked mini rigs. Spell as a second man on a cable percussion rig and currently holder of an NVQ Level 2 specialising in mini-drilling.

Involved in several hundred London Site investigations and London subsidence investigations. Other activities have included many London contaminated land investigations and Borehole Drilling investigations, trial pitting, undisturbed soil sampling, borehole instrumentation, site monitoring of landfill gas, water sampling and soil logging to BS5930. Office based assistance with collation of data and compilation of Phase 1 Desk Studies, and Phase 2 Site investigation reports and the computer presentation of borehole logs, drawings and laboratory test results.

Consultant Engineering Geologist

Dr. J M Coulthard BSc., PhD., FHEA

Consultant Engineering GeologistOver 30 years experience in research, teaching and industry. After graduating in Geology and Chemistry carried out research on Liassic Clays in the Engineering Geology and Soil mechanics section of the Dept of Civil Engineering at the University of Aston in Birmingham. Subsequently joined the Civil Engineering Department at the University of Teesside teaching Soil mechanics and Engineering Geology. During this time was active in research in Engineering Geology and Particulate Science publishing over 30 papers and a textbook as well as undertaking various consultancy roles in applied engineering geology and Geotechnics.

Main area of research was the investigation of the engineering properties of the Boulder Clays and the Laminated Clays of the Tees Basin and their stabilisation using lime and cementitious materials. Also investigated (with co-workers) the Friction and Adhesion at Bulk Solids/Wall Interfaces in silos and storage bunkers.

Consultancy activities have been varied and numerous and have covered foundation and retaining wall design, soil and rock slope stability analysis and a wide range of applied engineering geology assessments.
