Banks of Loch Lomond
PERI has partnered with M & L Contracts Ltd to help restore the harmony of traffic flow along the shores of Loch Lomond in Scotland.
The A82, at a place named Pulpit Rock, winds along one side of the loch and is currently undergoing major re-construction work to improve traffic flow.
This has been hindered due to a major landslide which blocked one lane of the original road width.
The solution to these problems was the construction of a new road lane. However, due to the road restrictions the only option was to construct the new lane out over the banks of the loch, replacing the traffic light controls that have caused lengthy delays.
The new and sleek elevated concrete bridge structure posed many construction challenges for sub-contractor M&L Contracts, who were responsible for forming the reinforced concrete elements of the structure.
Partnering with Peri, special formwork solutions were sought and developed to meet the demands of this structure together with the limited road access to construction work areas.
The solution was found within the VARIOKIT product range, specifically in the VK-P platform system, which provides parapet support and access. This enables cantilevered concrete parapet slabs and up-stands to be supported from the main bridge superstructure and is prefabricated before placing on site.
Additional challenges were presented by the structure itself including a cross-fall and longitudinal curvature along the road route.
This well-travelled road had to remain open at all times as a single carriagewa
for everyday traffic and only minimal road-closures were permitted during some night time periods.
Overcoming these obstacles the PERI VK-P system and M & L Contracts expertise delivered the required solution with minimal disruption.
Peri detailed, designed and tailored the VK-P platforms so that they could work within the constraints of the roadway, with the equipment prefabricated at a nearby work area.
As well as supporting the concrete elements under construction, VK-P platforms also permitted construction workers to have ongoing access along the loch side of the structure during the main project phases, ensuring a safe working environment at all times in a difficult and exposed location.
Support service was provided by Peri’s technical design team who developed the formwork designs solutions and provided continued support to the customer with site visits.
Bill McKim, Senior Sales Engineer for Peri commented:
Both companies understood from the outset the challenges of the project; but were aware of the benefits the new roadway would deliver to this part of the country and Peri is proud to have been a part of such a great solution.
M & L Contracts project directors, Laurence O’Kane & Gary O’Kane said:
As the A82 new road structure at Pulpit Rock blends harmoniously within the curving shores of Loch Lomond, one can only say that it stands out only in the challenges it presented for us as formwork professionals and it is placed firmly near to the top of our best and unusual projects list.
