The Collyweston slates to the Bodley Building Kings College Cambridge were deteriorating and a sympathetic repair was needed to extend the life of the roof by 20 years. Whilst erecting the comprehensive scaffolding to access the roof slopes the scaffolding was extended to enable essential re-pointing and repair works to the stone chimneys. Working sympathetically with the College the project was completed in under 10 weeks without compromise of craftsmanship.
