Opportunity Overview
Trinity House has a requirement to conduct a number of Hydrographic and Bathymetric/Topographic surveys at regular intervals. The purpose of the upcoming tender is to put in place a framework lasting a maximum of four years consisting of innovative survey companies to carry out surveys around the coasts of England and Wales.
Hydrographic surveys required: Hydrographic surveys to be completed within pre-set boundaries. A potential need for these boundaries to be expanded due to significant changes whilst surveying will also need to be taken into consideration. Trinity House will require the entire data set to be submitted as we share this with the United Kingdom Hydrographic Office. Ideally the survey data will be collected in Caris. Alongside the dataset, we require .csar .hob files and a detailed Report of Survey.
Survey Quality: TH currently collect data to IHO Order 2 as a minimum, however tenders should aim to achieve a better standard. Surveys should capture 100% bathymetric coverage and should be multibeam bathymetry to IHO Order 1a, with our shallow water surveys being surveyed to IHO Order 1b. The MCA have a useful link to help show what is involved in order to collect the data to those standards: UK Civil Hydrography Programme (CHP) - GOV.UK. The scope will also include the ad-hoc survey of new wrecks or dangers to navigation.
Bathymetric - Topographic surveys required: Trinity House holds the operation and maintenance responsibility for over 60 lighthouses around England, Wales, the Channel Islands and Gibraltar. These critical aids-to-navigation include several rock tower lighthouses that require regular modernisation and ongoing maintenance. To support this work, it is important to have accurate bathymetric and topographic surveys of the surrounding area(s). Topographic surveys are required to capture levels within the intertidal zone and areas that are inaccessible for bathymetric techniques.
