AVERT is a UK-based charity that has been providing accurate and trusted information about HIV and sexual health worldwide for over 30 years.

The site had a mixed history, at one stage being an engineering works. At the time of our investigation no proposals for redevelopment or conversion of the site were known. We undertook a Phase 1 environmental report for a site in West Sussex to assess the risks to sensitive receptors both on and off-site due to soil and groundwater contamination as a result of redevelopment.


Sustain advocate for better food, farming and agriculture policies and practices that enhance the health and welfare of people and animals, improve the working and living environment, enrich society and culture and promote equity.

One of their projects, which we gave advice on, involved developing community allotments and new growing spaces for London.

We conducted soil testing and site investigations for 13 sites throughout London.

OnSide Youth Zones

Instructed by: H L Engineers


Our commitment was to provide a Phase 1 Environmental Report and a Phase 2 Geo-Environmental investigation for sites in Barnet, Croydon and Barking & Dagenham

The Project:

OnSide’s Youth Zones are designed to give young people aged 8–19 years old (25 for those with a disability) somewhere to go, something to do and someone to talk to in their leisure time; occupying their bodies and minds with fun activities, learning new skills and socialising in a safe, positive way.

OnSide Youth Zones are there for young people in deprived areas, where the alternative for many is spending their evenings on the streets or isolated in their bedrooms, surfing the internet.

The project proposed erecting three sports facilities with soft landscape in areas of parkland in the three boroughs. Various challenges were presented such as an operational military airport just next to the northeast boundary of the Barnet site.

We were instructed to design a suitable investigation strategy, visit site and take soil samples and complete a report on the suitability of the site for its proposed use.


Purchase of this residential property was being considered, however there were concerns of potential contamination, not least due to the proximity of a petrol filling station. Unfortunately in this instance the suspicions were well founded and the site found to be unsuitable without undertaking costly remedial works.
