We are able to provide a comprehensive range of services to assist you with your development and specialise in the investigation, assessment and development of brownfield and greenfield land. In addition we are able to assses the likely issues that may arise from the construction and operational phases of your development.

Since our establishment in 1993 Smith Grant has accumulated a vast array of experience with all types of development. Typically, brownfield sites require an initial screening assessment to provide an historical framework of past site activities. This may then lead to a more detailed and intrusive investigation to identify if issues are present that may affect the future use of the site. These issues may, for example, concern ground contamination or ground and surface water pollution. It may also be possible to identify potential impacts that may arise during the construction and operation of the future development e.g. dust and emissions from construction traffic and emissions from industrial processes.

Often developments may have a number of potential impacts affecting land use, ground water and air quality. To address this we are able to integrate our land, air and water services to provide a comprehensive solution to meet the needs of your development.
