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.

The client request was simple, “can you provide us with a contour model of our site in Guildford”, the challenge was that the site was a sheer sided disused 25m deep chalk quarry. Health and Safety considerations meant that the quarry sides or base could not be accessed by the survey team to take measurements. The solution was to undertake the survey using a Riegl Laser Scanner with a Nikon digital camera mounted on top.  The scanner records up to 122,000 points per second and has a range of 600m whilst being able to achieve a 3mm accuracy.

Following development with the Crossrail safety team specifically to fulfil their TARGET ZERO strategy, we are delighted to offer this specific type of survey as a new service to all clients. The Excavation Risk Assessment is a Utility Survey of a single site where an excavation is planned. The survey is undertaken using both radio location and ground penetrating radar techniques and the completed drawing of the site area is produced on one double sided A3 sheet. The finished survey drawing contains a plan of the site, a cross section and a written description of the utility hazards that an excavation crew will come across.  The style of the drawing has also been designed to enable any excavation crew to quickly and clearly understand the hazards so that the excavation can be undertaken safely.

The new ‘all-in-one” Scanstation C10 delivers faster, more accurate survey points in High-Definition. The Scanstation is much faster than its predecessor, capturing full dome scans up to 10x quicker.   It now takes less than 2 minutes for a typical sized room.

Building surveys can be undertaken for many different situations. Each purpose will require a certain degree of accuracy, which will affect both the time taken and the cost of the survey.
Measured building surveys can be undertaken for the following;

• Interior Design
• Structural alterations
• Refurbishment
• Net Internal Areas
• Fire layout plans
• Modelling & Visualisations
• Rights of light & Party wall issues.
• Planning
