Marcus leads the London Gateway Environment Team and manages one of the largest terrestrial and marine programmes in Europe. This has included an extensive ecological relocation programme involving translocation of over 300,000 protected species to receptor sites in Essex, Hampshire and Wiltshire, creation of two new mudflats to compensate for the loss of intertidal areas , managing a national significant site of Roman archaeology and undertaking an archaeological clearance programme which has uncovered some fascinating artefacts which are going to be displayed in local museums , and successfully remediating the old former refinery site ready for the construction of the Port/Rail and Logistics Park.

Investment in local community projects and initiatives has been and continues to be a key component of the work, ranging from community outreach programmes, engagement of local business, particularly farming, Fisheries Local Action Groups and improving public access to local wildlife areas.

London Gateway Port has been operational since November 2013 and an extensive programme of construction and development is still to be undertaken. The works undertaken to date have demonstrated that you can construct a large commercial development, create jobs, and manage a complex environmental programme in a sensitive Estuary location.

Prior to this Marcus has 25 years' experience in environmental working on major construction projects both in the UK and Overseas. This has included managing environmental programmes for the London 2012 Olympics for CLM, Terminal 5, Channel Tunnel Rail Link and the Jubilee Line Extension Project.
