College Bridge Wins Wood Award

Newbattle Abbey College’s grotto bridge fended off competition from all over the UK to win a coveted accolade from the 2010 Wood Awards. The college’s bridge, which was designed by Forestry Civil Engineering and constructed by JKF, was deemed the Best Use of British Timber this year at the recent Wood Awards annual ceremony.
Newbattle Abbey College and Forestry Commission Scotland (FCS) entered into a Concordat agreement in 2009 to replace the 16th century building’s existing grotto bridge, which was installed in the 1940s by the Army when they occupied Newbattle Abbey and was found to be too costly to repair in recent years.
The new bridge was built from air-dried, pressure-treated Scottish Larch to give maximum durability and sustainability and was praised by the Wood Awards’ judges for its structural innovation. The bridge links the college, which is the only adult residential college in Scotland, with the neighbouring and historic Lord Ancrum’s Wood.
Ann Southwood, Principal of Newbattle Abbey College, commented: “We were delighted with the support we received from Forestry Commission Scotland to secure funding, architects and construction partners for the bridge. It perfectly complements the college’s building and our surrounding grounds and we are sure it will retain its charm for many years to come.
“Rebuilding the grotto bridge was an essential element of our estates strategy, as it connects the college to Lord Ancrum’s Wood. This will benefit both the college and our local community by giving them access to a safe and diverse woodland which is rich in both biodiversity and history.”
Dr Geoff Freedman, Forestry Commission Civil Engineer said: “We are all thrilled to bits to win this award against some amazing competition. It really shows that the Commission’s engineers are at the cutting edge of timber design and innovation.
“The bridge is a shining example of just how fantastic and versatile home grown timber is and how it can be used to blend in with its surroundings.”
The bridge represents a huge achievement in terms of the innovation used in its design. The vertically laminated structure was a glued and screwed timber arch supporting a flat deck designed for rural crowd loading or light vehicles. The design was based on the research work done by the designer as part of a PhD study on stress laminated arch bridges. This form of construction allows 100 to 1 span to depth ratio which is efficient in material terms. This is possible because timber is good in bending and compression. The timber was air dried; pressure treated Scottish Larch to give maximum durability and sustainability.
Newbattle Abbey College was founded in 1937 when the 11th Marquis of Lothian, gifted his 16th Century home to the Scottish nation.
This year we are celebrating 75 years of providing adults with a second chance to access education.
