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.

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 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.
