Structural engineers have utilized 3D imaging to examine the steelwork beneath Blackpool’s iconic piers and identify areas in need of maintenance. Detailed computerized images have been created for North Pier, Central Pier, and South Pier, highlighting areas where steel is missing and providing precise dimensions for necessary repairs.
This innovative approach is assisting The Blackpool Pier Company, which owns all three attractions, in prioritizing where investment should be directed. Mark Marshall, health and safety officer for the company, explained that the technology allows engineers to conduct a comprehensive assessment and develop a repair program with clear priorities. While physical inspections of the steelwork are still necessary, the use of 3D imaging provides an audit trail of all repair works.
The 3D imaging can be regularly updated to ensure current data, enabling more efficient scheduling of maintenance. The next major investment will involve replacing three trusses at North Pier, located behind the North Pier Theatre, as well as some main support beams beneath the pier. Scaffolding will be used during the repairs, and temporary beams will be employed to support the theater.
Mark Marshall emphasized the challenges involved in maintaining these Victorian-era piers, which were originally over-engineered by about 50%. The upcoming work at North Pier has been carefully scheduled over a couple of years to accommodate the involvement of specialist engineering companies. The availability of 3D surveys for each pier has proven invaluable in assessing and prioritizing necessary repairs.
North Pier, the oldest of Blackpool’s three piers, is celebrating its 160th birthday this year after opening in May 1863. Central Pier, known for its famous ferris wheel, was built in 1868, while South Pier, with its fairground and thrilling rides, opened its doors in 1893.
