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.
