Commonwealth Games Athletes Village
Customer: Glasgow City Council
Value: £5.9 million
The contract involved a programme of remedial work in
preparation for the development of the 2014 Commonwealth
Games Athletes’ Village. The site identified for the Village was
a mix of residential, industrial and open spaces with significant
areas of vacant land. There were approximately 859 households
with a population of 1,600 in the immediate area.
The works involved site clearance to allow the selective
excavation of around 140,000m³ of contaminated soils and
materials from various areas across 33 hectares of the proposed
site, with the majority being processed and treated on site to
permit its reuse. Approximately 100,000m³ of the material
underwent soil washing using a bespoke plant assembled and
operated by VHE specifically for this contract.
Treatment of invasive species such as Japanese Knotweed and
Giant Hogweed was also undertaken during the works.
VHE also employed archaeology specialists to inspect, identify
and record any historical structures expected to be uncovered
by the remediation works.

Shawfield Regeneration
Customer: Clyde Gateway Value: £3.1 million
The Shawfield Remediation Project enabled Clyde Gateway to undertake the task of
remediating large tracts of previously derelict and contaminated land in order to launch
the National Business District (NBD) which will bring 10,000 jobs to the area, meeting
50% of Clyde Gateway’s overall employment target.
The remediation of the Phase 1 site required close collaboration across the supply
chain to deliver the project using an innovative process for the treatment of hexavalent
chromium at depth, believed to be a first in Europe, and the re-cycling and re-use of
existing demolition materials within the site.
Due to the size of the site and the development of an effective treatment process using a
more reactive chemical reductant, the project team designed and constructed a bespoke
batching, mixing, distribution and injection plant on a scale never seen before with a
central batching area delivering chemicals to ‘satellite’ injection teams.
“Following review by industry leaders, this project was Highly Commended for
Sustainability at the 2015 Ground Engineering Awards.”

Over the years VHE has obtained an enviable
reputation for successfully delivering
infrastructure projects throughout the UK
for which we have received excellent client
feedback praising our high levels of
customer service.
Recently, VHE has undertaken works on
regional highway schemes worth up to
£20 million in value. These include both
public infrastructure schemes as well as
those in the commercial sector.
This infrastructure capability complements
our land remediation activities and enables
our customers to benefit from an integrated
approach to all their civil engineering
requirements.
One of our main advantages is that we can
combine the drainage, earthworks, highways
and structures elements to provide the customer
with the most efficient, cost effective solution
and seamless interface between site activities.
We have developed excellent long-standing
relationships with a large number of local
authorities, with whom we work on partnering
frameworks.
Our success was recognised by the Institution
of Civil Engineers Yorkshire and Humber as we
were awarded the Centenary Award Certificate
of Excellence for the work we undertook on
Cudworth & West Green Bypass in Barnsley.
Cudworth and West Green Bypass
Customer: Barnsley Metropolitan Borough Council
Value: £16.0 million
The eagerly anticipated scheme will reduce the amount of
traffic, especially heavy goods vehicles, using the A628 though
Cudworth, and improve access to local employment sites.
The scope of works comprises:
• Construction of 5.2km of new single carriageway.
• Construction of 5 roundabouts, a rail bridge over the
new road, a road bridge over the new road, 3 underpasses,
9 box culverts for water flow storage, major drainage
works, street lighting and signage.
• Design of the drainage, structures and surfacing.
VHE installed a 110 tonne rail bridge as part of the scheme.
The 22m long bridge was lifted into position by a 800 tonne
Demag AC700 crane during a 28 hour rail possession.
VHE and specialist rail subcontractors CML required only 30
minutes to install the single span bridge deck.
The route runs through the embankment underneath the
existing single track rail line connecting manufacturer Ardargh
Glass with the Wakefield to Grimethorpe rail line.

Remediation Contracting Services to the UK Power and Utilities Industry
VHE has undertaken a wide portfolio of schemes in the power and
utilities sector from the provision of remediation and infrastructure
services on the redevelopment of a major power station site to minor
remediation and improvement schemes.
A large number of projects in this sector have also been carried out
under a long term framework agreement with National Grid. This has
involved the remediation of a substantial number of urban gas works
sites. VHE has been retained on the National Grid Framework since
1996 and successfully delivered over 400 schemes.
The projects undertaken by VHE in this sector have involved a wide
range of remediation techniques including bioremediation, soil
washing and soil stabilisation as well as demolition and in situ or ex situ
groundwater treatment, on sites up to 31 hectares in overall size.
In addition to power sector projects from fossil fuel generating sources,
VHE has also worked in the nuclear power sector on highly challenging
decommissioning projects in strictly controlled areas.

IESNeepsend Lane Gasworks
Customer: National Grid Property Holdings Value: £10 million
VHE has carried out five phases of work on the former Neepsend Lane Gasworks in
Sheffield on behalf of National Grid Properties totalling in excess of £10 million.
Remedial works undertaken by VHE included screening the overlying construction
and demolition wastes, selective excavation, treatment and disposal of contaminated
soils associated with the former gas works and groundwater treatment. The overlying
construction and demolition materials were excavated and screened to remove waste
materials such as paper, plastic, timber and metals in order to render them suitable for
re-use as fill on the site. This recovery operation reduced the amount of construction
and demolition waste removed from site to around 1.5% of the original tonnage.
In common with many former gas works sites, live plant was still present within the site
and had to be considered during the design of the works. The principal hazard to be
considered during the works was the presence of a live overhead 36” medium pressure
gas main, which crossed the site from east to west. This gas main lay approximately 2.5m
from the edge of two of the four 15m deep gas holders to be excavated and required
significant temporary works measures to be in place to provide additional stability during
the works.
A total of 17,000 tonnes of contaminated material was sentenced for treatment by
bioremediation. Primarily, bioremediation was used to reduce the classification of soils
from hazardous to non-hazardous in order to minimise the amount of waste consigned
to hazardous waste facilities. In addition, around 4000 tonnes was successfully treated
for re-use on site.
Hydrocarbon contaminated groundwater was extracted during remediation and pumped
to a water treatment area comprising 6 holding tanks and a treatment system. Treatment
comprised a 3 stage oleophilic, hydrophobic wired unit feeding a carbon filter pod.
All treated waters were discharged under a formal consent agreed with the local
water authority.

Since the business was established, VHE has developed an excellent reputation as a
leading UK remediation contractor that is able to deal with a wide variety of projects.
Many of these have involved the remediation of historical former landfill sites, a large
number of which were unlicensed with little control over the material deposited.
This experience and knowledge is invaluable to modern landfill site operators and
waste companies who are tasked with managing and developing their facilities in a
controlled and efficient manner.
In recent years we have constructed several hazardous and non-hazardous landfill
cells and installed drainage and leachate pipework as well as clay liners and gas
protection systems.
In addition, we have constructed
roadways, car parks, weighbridges,
wheel wash facilities as well as
office foundations. Our experience
in providing remediation services
means that there are not many
facets of modern landfill facilities
that we haven’t delivered.
