environmental and social

Managing environmental risks

The complexity and range of environmental and social impacts, together with the increasing pressures of legislation, stakeholders’ expectations and greater public awareness, means a systematic, fact-based approach is required to ensure the sustainability of a development project. Biodiversity, air, water, land, climate change, health & safety, resettlement – whatever the risks, we have the expertise to manage them.

Integrating our environmental and social expertise with architectural and engineering knowledge, our multidisciplinary teams offer sustainable solutions for infrastructures, industries and buildings. We provide expert guidance to manage risks and constraints, measure and improve carbon footprint, certify buildings and enhance sustainability and wellbeing.

Our environmental and social services

Expert witness

We have experienced experts available to advise on a range of topics related to sports surfaces, sustainable water management, ground gas and VOC migration and ingress, and geoenvironmental engineering. Our recognised experts provide clients with clear and robust expert opinion, grounded in our direct experience in environmental regulation, industry, local authority operations, and government policy.

Flood risk assessment

Our team will deliver the flood risk assessment (FRA), outlining the threat of flooding within the site’s surrounding area and providing measures by which the risk can be mitigated or avoided. Our team will also identify the potential source(s) of flooding, review flooding history, obtain critical water levels and determine the influences on river hydraulics. The assessment considers flooding from tidal, fluvial, groundwater, sewer, highway and on-site drainage sources. If needed, our assessments can cover a number of other factors such as loss of floodplain storage, washland modelling, flood plans, access and egress, sequential testing, exception testing and surface water drainage issues.

Through a series of alleviation measures and engineering options, we will design to determine the most cost effective and practical solutions to completely avoid or mitigate, within acceptable limits, the risk of flooding on-site or elsewhere.

Habitat management

Effective habitat management is an essential element of any development site. STRI ecologists are experienced in the creation, re-creation and restoration of a wide range of habitats, working closely with clients to develop an effective habitat management strategy to enhance the biodiversity of development sites and mitigate impact to protected species.

Our team creates or restores habitats by establishing new hedgerows, ponds or wooded areas, or, in the case of habitat loss due to development, the translocation of plants or soil from the original habitat to a new area of the site. Where appropriate, they will draw up and implement an ongoing management strategy to improve biodiversity, creating plans that provide clear and detailed mitigation and enhancement strategies for species, as well as broader habitat enhancement measures to maximise general biodiversity.

Land contaminated assessment

In order to identify land contamination, whether it be to support a planning application or for assurance when buying land, a contaminated land investigation needs to be carried out and, in some cases, commencement of a project may not be possible without one. Through detailed desk studies, site investigations and testing, we carry out contaminated land investigations, identifying and addressing land contamination to support the planning process and ensure regulatory compliance. Early engagement in projects on ‘brownfield’ (i.e. previously developed) land can help de-risk a project, in terms of the identification of potential additional costs and constraints in the ground, allowing the proposed design to minimise these at the outset.

Environmental and social impact assessment

Environmental Impact Assessment (EIA) is an integral part of planning and development. It is a process by which the anticipated effects on the environment of a proposed development are measured to inform the decision making process. The EIA process can often be seen as complex and confusing, particularly for key stakeholders. However, if managed well it offers an opportunity to de-risk development and enhance reputation. Our consultants understand the importance of a consentable development and our aim is to achieve a successful consent with the minimum of fuss that maximises commercial viability.

Ecology and biodiversity

Making a positive impact on biodiversity is becoming increasingly integral to the success of all construction projects, for both securing planning, and creating places where people want to live, work and play.

STRI ecologists and environmental consultants enable infrastructure and development to make a positive impact on nature, working with clients to plan, design and build infrastructure within the sports, residential and commercial sectors. We deliver survey, assessment and consultation services for biodiversity net gain, ecology and tree works needed throughout the lifetime of your development; from land purchase to post-construction management.

Public health engineering

Proficiently designed waste water systems are important to healthy, sustainable buildings. There are advantages to a well-designed, appropriate sustainable water management system; saving water and saving energy associated with its use.

Our expertise in completing challenging designs ranging from high-rise building drainage, rainwater and waste water recovery and re-use systems along with site-wide building drainage designs incorporating Sustainable Drainage Systems (SuDS), provides a platform to assist clients to create resilient buildings through efficient, effective water management design. Working closely with the project design team we can help to provide integrated building services.

Structural waterproofing

The continued demand for building development space has seen increased incorporation of basements beneath buildings in urban, suburban and even rural locations. Basements, particularly in cities, are expanding in depth and size with the space progressively being used for activities that are much more sensitive and susceptible to damp and water ingress.

Basements and other substructures can leak both during and after construction and the consequences of leaking substructures are numerous and invariably result in costs associated with remedial works, delays to programme in construction and expenditure and disruption to the building operation after construction.

We can undertake robust risk assessments and deliver appropriate waterproofing design on behalf of all development stakeholders, taking into consideration a broad range of parameters that will impact on the overall development design.

Our CSSW qualified team offers a full design service including detailed risk assessments, desk studies, project specific details, sections and drawings and project support.

We are experienced in producing structural waterproofing designs to BS 8012 and NHBC chapter 5.4.


Blue and green infrastructure

Mimicking natural systems either through natural flood management (NFM), SuDS or blue green roofs adds significant benefits to the local area including offering an element of nutrient neutrality to the development.

Offering blue green infrastructure is an ideal way to contribute to delivery of sustainable architecture, providing environmental benefits, lowers urban air pollution, grants access to green space, improves general well-being, and reduces energy consumption of the building. Our environmental consultants will support clients in understanding the desired biodiversity and habitat for the selection of the most appropriate green roof system.
