Laser Scanning – Verticality Deformation Survey

Technics Group were recently appointed to carry out a verticality deformation survey of a block of flats in Canterbury, Kent.

The site was a modern, three-storey block in a small residential development and consisted of two wings conjoined by a shared stair core. The interior exhibited some severe cracking suggesting a serious subsidence issue, which had led to the building being deemed uninhabitable and the relocation of the residents.

Structural Engineers David Osborne Associates commissioned  Technics Group to undertake the survey as part of their investigation and remedial design work.
The project requirement was to produce tabulated results showing deflections from vertical of the exterior walls and interior stair core walls at 31 plan positions, each at 10 level intervals from ground to soffit.

Contractor fined over worker’s jet of fire burns

A sub-contractor from Highley has been fined for safety breaches after a worker was burned by a ‘jet of fire’ when he hit an underground electricity cable with a steel pin while replacing pavement edging in Birmingham.

The worker, 38, from Bridgnorth, who does not want to be named, escaped with minor burns to his arms and eyebrows and had his clothing singed when the 415 volt cable sent a ‘jet of fire’ up the steel pin.

An investigation into the incident that took place on 16 August 2011 by the Health and Safety Executive (HSE) found Ricky Paul James, 46, the subcontractor responsible for the work, had incorrectly indentified the location of the live cable.

Technics Group Measure up for NIA

Accurate building Net Internal Area calculations have a variety of uses including as built assessment, marketing, H&S documentation and lease / rent calculations and are therefore essential for a project team. Being certain of the NIA allows the team to confidently progress and removes the likelihood of conflict. Technics Group have recently completed an NIA survey for the New Central development in Woking, Surrey.

The Barratt Homes development includes 445 Residential units together with 4900m2 office space over a six storey office block.

GPS – a brief explanation

GPS is the acronym for the Global Positioning System. It is a planet-wide satellite navigation and positioning system with applications ranging from in-car “SatNav”, guiding combine harvesters and airliners, positioning oil rigs and weapons guidance systems.

Land surveyors use it as a tool for precise positioning and also general surveying and mapping methods.

The system is a three dimensional measurement system which uses hand held and more precise survey instruments to receive radio signals from orbiting satellites to determine their terrestrial (surface) position.
