Lea Valley – countdown to 2012!

London 2012 logoWe would like to add our congratulations to the bid team on their success in winning the Olympic Games for the UK in 2012!

The proposed area for the Olympic village and associated infrastructure has a wealth of industrial history. It’s the sort of area Zetica thrives on investigating - brownfield sites with the potential for hidden risks that could cause delay to development. We already have a lot of experience in the area and we hope you will involve us if you are working on any of the projects.

In the past we have helped on many issues from locating wall ties on the canal and river banks to identifying unexploded bombs (UXB). Our Landsweep and Sitesafe services are most popular as they are aimed at providing a ‘heads up’ on the risk even before a borehole or trial pit is put into the ground. But do also remember our other services such as Engineering and Utility Services which offer valuable geotechnical and asset information to your engineers.

Whether you need to find a cable, a former waste tip, a buried storage tank, check for UXB’s, determine Gmax, depth to bedrock or the thickness of the road pavement, Zetica’s team is ready to help you characterise and map the subsurface.

Report on Open Day

A very successful event was held at Zetica’s Test Site in Enstone over 2 glorious days in June. A total of 30 delegates from across the construction industry benefited from a range of presentations on recent advances in brownfield site investigation methods including; the Landsweep™ concept, bomb detection – separating fact from fiction, developments in cone penetrometer testing, intrusive SI methods and integration of surface and borehole geophysics, CPT and drilling.

Frank round table discussions on the perceived strengths and weaknesses of different SI strategies and methods were held. The views of consultants, developers and contractors were all aired and a consensus reached that consultants would be interested in regular briefings on evolving technologies to help them design more cost effective solutions to SI problems. Developers and contractors generally appreciated the value of having a wide spectrum of SI tools to choose from and were interested in reducing cost and risk.

A challenge was put out to consultants to utilise boreholes and CPT tests in conventional investigations to better effect by combining them with either a site-wide surface geophysical scan to look for local anomalies to investigate and/or filling in the gaps between boreholes using borehole geophysical methods and sampling undisturbed ground using wireline geophysics.

The result will be more value for the SI expenditure rather than necessarily increasing the SI budget.

New combined CPT and Magcone tool launched

Lankelma and Zetica used the Open days held in June to launch a new tool for combining the search for UXB and mapping the maximum depth of UXB penetration / pile bearing layer. The combined Magcone- CPT tool, dubbed “Mag- CPT” can provide better value to clients commissioning a bomb search providing both UXB hazard detection and geotechnical materials characterisation in one survey.

An example of a combined Magcone and CPT log for a bomb at 3m depth is shown below.

Mark Whittingham Joins Zetica

We are pleased to announce the arrival of Mark Whittingham who has joined us from Met Surveys where he was senior project manager in charge of utilities and archaeological surveys. Mark has over 8 years experience of commercial geophysics with particular expertise in utility tracing surveys and mapping as well as data acquisition, processing and management experience of a wide variety of engineering geophysical methods.

At Met Surveys, Mark grew the geophysics team from 3 to 7 full-time geophysicists and is hungry for a new challenge which Zetica’s broad product range and aim to be the UK ’s no. 1 geophysical and mapping service provider, will certainly provide!

Free day of utilities scanning ?

Yes we would like you to sample the fruits of our experienced survey team recently bolstered by the arrival of Mark Whittingham. Once you’ve tasted Zetica you’ll never want to go back to anyone else again - we’d like to think so anyway. The offer covers all fees including mob/demob (within 150mi of Oxford), field work and reporting.

Click here to register to be in the draw which will be held on the 1st August 2005. The lucky winning company will be contacted immediately and their feedback on the quality of the service reported in the next newsletter. Even if you don’t win the main prize we’ll send you a Zetica pen for entering.

Lunchtime Seminars

Zetica offer a popular Geological Society registered seminar, with CPD points, on the uses and abuses of geophysics. Engineers are brought up to date on the latest geophysical methods available in the market place and interesting areas of research and development. The presentation normally lasts 30 – 40 minutes and is case history-based with a 15 minute discussion session following.
