Par is a tidal port containing three quays with berthage for up to 7 coastal vessels (maximum length 125m). Uses of the port include bulk drying of china clay for export (in 2000, 251 vessels shipped 458,065 tonnes) and importation of timber and road salt amongst other commodities.
Castria carried out an assessment of severely degraded sheet piling and associated deck structures before proceeding with a detailed asset appraisal and compilation of a schedule of works for upgrading and enhancing the current port structures, together with its operations, as part of the proposed regeneration of Par Harbour. A major programme of strengthening and new structures was planned. Works included new sheet piling, dock surfaces for very heavy loads, fendering, safety ladders, and improved aggregate storage infrastructure. Investigations include geotechnical studies, wave action and modelling, and an economic option study for strengthening versus new build. Ancillary works included a review of port access from the highway and existing rail links.
Fowey Harbour is a tidal and deep water facility; a very sensitive estuarine environment, encompassing five operational jetties (two date from 1923), a railhead and substantial 1000 tonne/hr ship loaders. Castria carried out an economic appraisal of jetty structures, together with design and upgrade works that included strengthening. Consultations with the Environment Agency and Local Planning Authority were required. The project also included some essential coastal protection works.
