Infrastructure
Teesport No 1 Dock Reconstruction
Civil and structural design of a new quay at Teesport, situated within the PD Teesport Ltd Tees Dock Estate on the south side of the River Tees, approximately 1 mile upstream from the mouth of the river. The works included full design and build services for 975m of quay reconstruction to a berth depth of -14.5mCD.
The development involved replacement of the existing deck, constructed in the early 1960s which due to deterioration and increased loading requirements had become unsuitable for the required useage. The berths were typically required to accommodate Panamax (typically 225m LOA x 32m beam) and Handymax (typically 190m LOA x 30m beam) vessels in close proximity with future provisions for a Minicape sized vessel.
Key details
Project name
Teesport No 1 Dock Reconstruction
Client
McLaughlin and Harvey on behalf of the client PD Teesport
Location
North Yorkshire, United Kingdom
Services provided
- Maritime infrastructure
- Civil engineering
Challenge
The existing quay was located in a working port environment and the project scope required RPS to address a number of engineering and logistical challenges including:
- Heavy loading conditions from harbour cranes and general
- 200kN/m2 Hinterland loading was specified at which also imposed large lateral loads into the back of the open piled superstructure. A rear sheet piled cut-off wall ensured that these loads did not cause failure to the top of the revetment.
- Phasing construction to minimise disruption to port operations
- Uncertainty regarding the residual bearing capacity of the existing deck which had suffered corrosion of post-tensioning tendons
- Optimisation of the sequencing of demolition and construction works
Solution
As lead designer RPS worked closely with the Contractor to develop a solution that was both practical and economic and which reduced risk associated with the uncertain capacity of the existing structure.
Early consideration of the variable ground conditions on site and the adoption of a test pile solution to optimise pile design allowed RPS to produce a detailed design that met all the needs of the Client and the Contractor.
The phasing and implementation plan included the provision of temporary bollards in order to allow vessels to berth alongside locations where the deck was partially demolished during the construction phase thus ensuring minimal disruption to the working quay.
An innovative design using a curved section of flat web sheet piles ensured that the toe of the revetment was retained in position during the works leading to an overall economic design.
