We are very proud to announce that our Seahouses Main Pier project won the "Civils Project of the Year" award at the Constructing Excellence National Awards 2020. Our Whitby Piers project was "Highly Commended" in the Heritage Conservation Project category. 

Seahouses Main Pier 

Seahouses Main Pier, the harbour and the adjacent coastline are valuable tourism assets and are of recreational and social importance to the local community. The harbour plays an important role in the regional infrastructure: it is the sole gateway for pleasure boats visiting the Farne Islands National Nature Reserve, provides shelter to the fishing harbour and protects backing properties against sea flooding and coastal erosion. 

Assessments of the condition of the Seahouses Main Pier revealed extensive deterioration, large holes and cracks within the structure and identified deterioration at an increasing rate. The pier was estimated to only have 10-15 years of remaining effective life. 

Royal HaskoningDHV and Balfour Beatty joined forces in repairing the pier in a £3 million project on behalf of Northumberland County Council (NCC). Because of the highly sensitive marine environment hosting numerous (inter)national nature conservation designations, high standards were set to the design and constructive methods to ensure the environmental acceptability of the works. 

Value engineering and innovative techniques, such as hydro-demolition as an underwater construction method for breaking out a toe trench at the foot of the pier, were used to help accelerate programme and reduce overall scheme costs to affordable levels. A tight construction programme ensured substantial completion before the arrival of over-wintering birds.

The project resulted in extending the service life of the pier for another 100 years, preventing loss to the local economy by safeguarding jobs and income associated with the fishing and tourist industries operating from the harbour. The completed restoration protects 165 properties (26 businesses and 139 homes) from coastal erosion and sea flooding risk. 

Whitby Piers

The Whitby Harbour, located on the North Yorkshire coast, is a functional fishing harbour that supports a local maritime industry. With its picturesque setting and significant cultural, geological, environmental and heritage interest, the harbour is vital in supporting a major tourism industry in Whitby. 

Its famous Grade II listed West and East Main Piers were in a poor structural condition, exhibiting a significant number of defects. Capital works were required to refurbish the structures and extend the life of the existing Main Piers as a critical coastal defence assets. On behalf of Scarborough Borough Council, Royal HaskoningDHV and Balfour Beatty teamed up closely in this challenging £6.76 million restoration. 

The construction work was susceptible to unpredictable weather and undertaken in a hostile marine environment, working in tidal conditions. Through careful planning and coordination, construction was completed safely, five weeks ahead of programme and under budget, with the design, construction methods and materials used being sympathetic to heritage status of the structures.
