The importance of carrying out bearing and expansion joint inspections by proficient and competent engineers who understand their functionality can often be key to maximising a structure’s lifespan and avoiding major, unexpected, emergency repair costs.
USL Ekspan have carried out a number of projects for swing bridges and foot bridges. From design, fabrication of all structural components, to trial erection and final installation. Details of these type of bridge installations can be supplied on request.
USL Ekspan was approached by Nexus to offer the optimum solution to replace the existing joints. After fully reviewing the scheme requirements giving regard to movement criteria, speed of installation and proven track record, Britflex BEJ was chosen as the ideal replacement system.
Works needed to be completed over one weekend during daytime working hours Saturday 0800 to 1800 hours and Sunday 0800 to 1800 hours, this was to reduce any noise issues to nearby residential properties.
During closure periods existing joints would require removing in advance of surfacing works with temporary plates installed to prevent debris falling through structural gaps onto the live track below.
To complete the joint installation works within one Sunday shift and in order to meet the client's requirements USL Ekspan would be required to mobilise six number joint installation crews to site (three at each joint location).
USL Ekspan attended site 0800 hours Saturday morning to remove the existing expansion joints prior to handing the site back to the client to undertake planing and resurfacing operations. USL Ekspan returned to site Sunday 0800 hours to saw cut and break out new surfacing to form the requisite joint cut out width.
Installation of 54.3 metres of the new Britflex BEJ 5 expansion joints to both locations commenced 1000 hours Sunday.
As required and planned for, the works were completed and open to traffic by 1800 hours that day.
