Halcrow is a leading provider of marine and coastal environmental services to support the planning, design and construction of marine and coastal structures around the world

We are a world leader in the planning, design and construction supervision of port & terminal facilities, marine structures and coastal developments - often in environmentally sensitive locations. To meet this challenge, Halcrow has firmly established itself as a leading provider of environmental services to the marine and coastal sector around the globe.

Our marine and coastal environmental services address all aspects of ecology, archaeology, fisheries, socio-economics, recreation/amenity, and navigation, and range from detailed benthic surveys and interpretation through to regional studies, high level advice and strategic planning for Governments.

A key part of any coastal and marine facility development is to establish an understanding of its environmental impacts, not only in order to develop a scheme that will be viable and sustainable, but also to allow the preparation of the supporting documents (for example environmental assessments) that often are a pre-requisite for the obtaining of approvals and licences. Our success is dependant on rapidly gaining a good understanding of the existing environment, any potential constraints and integrating appropriate mitigation into the design or operation of the facilities.

The nature of Halcrow's activities, and the way in which our project teams of engineers and scientists work together, allows us to bring to any project the experience warranted for most marine and coastal environments.

Consequently a key strength is to apply to projects our extensive knowledge of marine technologies and their commercial and environmental impacts to achieve practical, cost effective, sustainable and commercially viable solutions.

To support this, Halcrow has extensive experience in the measurement and modelling of wind, wave and tidal driven circulation and their effects on the stability of the sea bed to provide the basis of the planning, design and monitoring of all coastal nearshore and offshore facilities.

Our expertise covers:

  • environmental Impact Assessments for:
    - capital and maintenance dredging and disposal
    - aggregate assessments
    - port and airport development
    - coastal mixed use development
    - coastal infrastructure
