£4M Kier Berryfields

Project Principals and Objectives

The project was to construct the externals to a new Energy From Waste Facility (EfW). These works included concrete service roads, asphalt access roads and pedestrian paved areas using Marshalls various size slabs, conservation kerbs and resin gravel areas – in total approximately 2,000m2. The paved areas included street furniture as well as landscaped areas including tree planter and root systems.

Innovation and Best Practice

The detailed planning and communication strategy ensured works were carried out as planned and minimised any disruptions throughout the works. The application of best practice principles ensured finishing was complete first time. This facilitated the successful handover of the required areas as soon as they were complete could be handed over for full completeness and final operational use. Moving Forward

The success in this project reinforces our commitment to early engagement and a close partnership with our clients. Our clients can be certain that we have their objectives at the centre of what we do. We operate exclusively with a small pool of subcontractors so we can be certain of quality, safety and delivery.

Solution Focused Approach

The project was within a live site with key interfaces with various main contractors constructing the facility. The external works required key planning and coordination to ensure all trades were not delayed by the external works with access being required at all times. Detailed phase planning was essential.

Weekly progress and coordination meetings were carried out providing details of exactly where and when the weeks work was to be carried out. All works phased as such to mitigate any down time by other trades and the operating facility of the new site.

Another key requirement and specification was that the external works had to be carried out with immediate zero defects. A dedicated finishing squad and manager was utilised to ensure this was carried out.

Airport maintenance contractor

Since 2012 we are the current London Luton Airport framework civils and building contractor and as such are responsible for taxiway and runway maintenance and general airport infrastructure maintenance.

We have a committed team specifically responsible for this contract and the six-year proven track record is testimony to a well-run contract. Our duties include daily, weekly, monthly inspections, proactive and reactive maintenance and a 24 hour call out service.

For the last eight years we have managed and implemented nine consecutive night closures, during which all non-essential repairs/ maintenance is undertaken. This includes runways, taxiways and general airside infrastructure.

£4M installation of a new Airfield Ground Lighting (AGL) system at London Luton Airport

In 2013 Ryebridge worked on the installation of a new Airfield Ground Lighting (AGL) system at London Luton Airport for Inviron, since taken over by European technical services provider Imtech. The team were involved in this project from the very first stages, tasked with producing the civil design elements. Once these were signed off and of course shown to be CAA compliant Ryebridge then constructed the pits and just over 4,000m of ducting in the airside environment. It also performed the slot-cutting and sealing work, again to CAA standards.

Installation of new Surface Movement Radar tower and antenna for INDRA

For new client INDRA the Ryebridge team removed the old tower and installed a new Surface Movement Radar tower and antenna. Ryebridge completed all works including foundations and piling, tower erection, all in co-ordination with NATS and ATC.

The existing surface movement radar (SMR) tower had to be replaced and as such a new tower had to be constructed to facilitate this and the current health and safety regulations around working at height. Ryebridge were tasked with designing and building the foundations for the tower and to project manage the construction of the new tower and the installation of the new SMR. On completion we were then tasked with the removal of the old tower and radar. This was all done adjacent to London Luton Airport’s Taxiway Alpha, the main artery of the airport.

The project was completed on time, on budget and without any major disruption.

Sports and leisure

From swimming pools to gymnasiums and tennis courts to running tracks and football pitches, Ryebridge Construction are experts in the sports and leisure sector.

£600,000 Redhill Aerodrome

Ryebridge was appointed by Surrey’s Redhill Aerodrome to realign its existing runway, which forms part of the perimeter taxiway, and to remove the curve within it. The runway was closed for the duration of the works, with the remainder of the airfield open and maintained for light aircraft traffic including helicopters.

The close proximity of an area of environmental significance provided unique challenges to Ryebridge, who put in additional measures to prevent water contamination.

An envirobund was constructed to protect flora and fauna and to help with the water run-off, along with temporary diversion ditches designed to prevent run-off entering the water course until the final drainage was installed.

Works involved:

• Partial full depth breakout of existing runway, returning it to soft with compliant gradients to EASA – 1600m2
• Removal and disposal of contaminated asphalt
• Full depth construction of new aircraft pavement to widen and realign runway
• New asphalt surfacing over the newly constructed realigned runway including an asphalt reinforcement grid – 7500m2
• Groove finished asphalt surface
• The reinstatement of surface markings
• Installation of a new drainage system
• Regrading and landscaping

HV Ringmain project installing 11km of cable

In the 2015 Ryebridge was proud to receive a third consecutive RoSpa Gold Award for its work on the HV Ringmain at London Luton Airport, where in partnership with Bowers Electrical Ltd they updated the 50+ year old High Voltage infrastructure that feeds the airfield.

Ryebridge installed 11km of HV cable around a live airport environment having only one minor cable strike throughout the whole job. It installed a new substation, high voltage cable diversion/installation and Thrust Boring under taxiways and runway.

To reduce damage to the airports runway and taxiways, Ryebridge implemented horizontal directional drilling (HDD), a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path using a surface-launched drilling rig, with minimal impact on the surrounding area, something that Ryebridge always strives to do.
