Case Studies Pinner Park

The client wanted to redevelop land under its current ownership for the benefit of the community, but needed a change to current land use and buildings to do so. As part of the development design and consultations Norton & Associates was commissioned to carry out an Extended Phase 1 Habitat survey.

This included mapping of the ecological features of the site, assessing the presence of species that might have a conservation concern and identifying legal and planning policy constraints. We set out a range of proposals that could be pursued as part of the master planning process to enhance the biodiversity value of the site, including further protected species surveys of Birds, Bats, Badgers and Great Crest Newts located within the area.


We have experience in collecting data and mapping civil structures, having provided asset surveys and inspections for many years to the railway industry. Depending on the nature of the survey, we can produce reports and drawings with GPS, Laser, LIDAR and Aerial formats, using the latest technology to incorporate images and data.

We were commissioned to carry out ground investigation tests to numerous sites in preparation for an upgrade to London Underground’s signalling system. We project managed the investigations, most of which had many issues regarding difficult access, permitted works and plant approvals.

Our investigation included hand excavation pits, concrete testing, soil sampling, cable percussion boreholes, laboratory & WAC testing and asbestos screening. With the data , our client was able to produce structural drawings.

Case Studies Vegetation Surveys / Track

London Underground instructed us to conduct a full survey to map and classify the vegetation associated with the Jubilee, Northern and Piccadilly Lines.

We surveyed 130km all trackside land having arranged all necessary documentation, access, training and protection. All the information collected was uploaded into our GIS and land management database system with enough data to risk assess all vegetation with regards to track safety.

Our client used our survey data, to manage their vegetation more effectively and reduce disruption to trains.


At Norton & Associates our role is to help establish what’ s on your site, and how it can be dealt with, in accordance with current regulations. We offer walkover or detailed surveys to establish the presence of plants such as the Himalayan Balsam, Japanese Knotweed, Giant Hogweed, Rhododendron Ponticum and various Cotoneaster species,listed under Schedule 9 of the Wildlife and Countryside Act 1981.

Case Studies London Underground

In accordance with our brief to manage the vegetation across a large expanse of land, our client wanted to know where the non-native invasive species occurred, specifically Japanese Knotweed, Himalayan Balsam and Giant Hogweed.

350km of trackside was surveyed as well as many associated off track locations across London Underground’s network. All of the sites were mapped, data collected, plotted in GIS and recorded on our database. As a result, our client has set up a system for recording and monitoring these species and has instigated an ongoing maintenance programme of control.


With an experienced and varied team of surveyors, we provide many types of building and structural surveys for all forms of construction. Whether a survey is required for an individual’s property, a railway structure, or an industrial site we offer a complete, knowledgeable service.
