Severn Partnership; a busy start to 2012

Severn Partnership: Providing a Level Perch

Since the start of 2012 the Severn Partnership have been working flat out on projects around the country. This has included ongoing High Output Track Renewal (HOTR) projects, work at Paddington station, the surveying of numerous bridges and the scanning of factories and a golf course.

We would also like to welcome two new members to the Severn Partnership team; Jonathan Harman and John Woods who have joined our survey team. With a busy schedule ahead look out for more blog posts of ongoing and completed projects.

'Read All About It' - Severn Partnership in the Birmingham Post Newspaper

Birmingham Post - 'Innovators look to the world and double turnover.'

If you happen to pick up a copy of the Birmingham Post this month and flick to page 7 of the 'Entrepreneur' section you will see an article on the Severn Partnership with our accountants RSM Tenon; 'Innovators look to the world and double turnover.'

The article has been written to discuss the success of the Severn Partnership over the previous few years with the help of RSM Tenon. It was back in 2004 that Mark Combes and Nick Blenkarn took the reigns of the company which now works extensively throughout the UK and worldwide providing a range of innovative solutions including railway surveying, 3D laser scanning, 3D modelling and Scan2BIM.

To see the article go to the Birmingham Post Online (remember page 7)

Great Western Mainline Electrification Project - Structural Clearances

Great Western Mainline Electrification Project - Clearance for 150 Structures

Is it going to fit?

Severn Partnership has been assisting a major engineering consultancy in answering this question for 150 Structures on the Great Western Mainline as part of the Great Western Electrification Project.

Severn Partnership High Accuracy Railway Surveying

Severn Partnership Surveyors have been producing Topographical Surveys to establish Clearances for blacklisted structures and provide sufficient information surrounding the structure to allow for alteration proposals.

The 8 month long project, which ran on time saw at its peak up to 10 structures surveyed in a single night shift.

There were no incidents and Severn ensured that all the data was to the highest Quality, measured Safely and Delivered Professionally on Time.

Topographical Surveys for Structural Clearance Analysis

Track Renewals - Track Alignment & Cess Detail Surveying

High Accuracy Track Alignment & Cess Detail Surveying

With the continuous need to replace rail track, the Renewal train has played a vital role in delivering this rapid renewal system.  Working alongside this, Severn has provided the high accuracy survey data critical to its continuing success.

Track Renewal Train - Railway Surveying

Recently Severn have completed over 80,975 yards (approx. 46 miles) of topographical track alignment and cess detail survey along a section of the busy WCML LNW Route.  This work produced 30 digital survey models in both MX Genio and AutoCAD formats and 373 separate SC0 files for ClearRoute Gauging Analysis.

80% of the work was carried out in a Green Zone working environment, utilising both midweek night line blockages and weekend T3 possessions.  All the work was produced to the highest quality standards and delivered professionally on time.

Crossrail High Accuracy Surveying for Tunneling Monitoring

Crossrail Amberg Kinematic Laser Scan Point Cloud - Track

 As the Crossrail project starts it’s tunneling under the streets and infrastructure of London a huge amount of preparation work is going on to prevent monitor and  subsidence. 

Crossrail Amberg Kinematic Laser Scan Point Cloud - Paddington

Tunneling has already begun from the Western Portal, just outside Paddington Station, where The Severn Partnership has been busy compiling a comprehensive data set to be used for the monitoring of Network Rail infrastructure as the huge Tunnel Boring Machines (TBMs) munch their way underneath. 

Crossrail Paddington P-way Track Survey

Combining High Accuracy Leica TS30, 0.5 arc second 0.5mm, Total Stations with the latest Amberg Track Geometry Measuring Devices to coordinate every track and cross over unit on the approach to Paddington Station has provided the Crossrail team with a benchmark survey to monitor changes against. In addition a Kinematic Laser Scan Point Cloud provides a 3 dimensional model of all overhead line equipment and gantry structures prior to the TBMs passing underneath. Should any movement occur during tunneling, the entire stretch of track and infrastructure can be precisely reinstated with confidence. If all goes to plan, no one will even know the machines have been there....

Railway Track survey and GPS Control - A frosty start to 2011

Severn Partnership has had to come out “the blocks” at an electrifying pace in 2011 with over 70 miles of mainline railway already surveyed.

Railway surveyors on track in the snow

Railway Track surveys included:

• St. Pancras to Sheffield  – Midland Mainline over 48 Miles of track surveyed making also making use of the GRP5000 kinematic laser scanning system wit the latest clearoute software from Amberg Technologies.
• Walsall to Rugeley Trent Valley – RRN – 12 Miles of railway track including fence to boundary fence for the West Midlands Signalling Renewals.

Quality survey data is being delivered to the clients using Severn Partnership’s experienced railway surveyors who are all PTS qualified with Senior Surveyors being COSS qualified.

Large scale geodetic networks are observed using upto 16 number GPS units, simultaneously at times. This is backed up by bespoke Railgrid software experience in which has been gathered over the last 7 years and the commissioning of 9 Railgrid mapping projections including the MM07 Snakegrid for Midland Mainline in 2007.

Railway survey in Poland - Trako conference

Managing director Mark Combes paid a flying visit to Gdansk, Poland to publicise Severn Partnership survey capabilities on large scale mapping, high accuracy Pway survey and railway surveying in general.  Linking up with UKTI midlands who promote the Midlands Rail cluster of rail specialist companies.  Mark met up with key contacts at the PKP, along with some of our key clients such as Mott MacDonald, Atkins, Halcrow, and Jacobs.

UTX Monitoring movement on railway lines

Our monitoring teams were called up to install a series of targets the monitor movement or live railway lines during the drilling of an undertrack crossing (UTX) near Kidderminster. Our cost efficient monitoring solution can be used to give real time movement reports, calculate displacement in x,y,z, rail twist, track CANT and absolute level. Survey teams will monitor movement while the drilling takes place from a place of safety and without being affected by the zone of influence.

High accuracy geodetic control and track survey

Our survey teams are just completing a project totalling 91 miles of high accuracy pway track survey and geodetic control; covering areas around Worcester, Bristol, Birmingham and down to Exeter. All data processed using a Snakegrid to ensure a near unity scale factor to aid future engineering survey and design.
