End of REnescience Project Report

Following the successful construction of the original REnescience scheme in Northiwich, Cheshire. Jennings were approached directly by Orsted (formally DONG Energy) to undertake the civils element of the extension works to house supplementary equipment for the existing waste to energy site. We worked alongside processes contractor, Colbalt Energy to deliver this scheme for the Client.

As anticipated, the reclamation of the brown field site proved very challenging. Specialist techniques were used to discover and remove buried obstructions for the proposed Vibro Stone Columns used to stabilise the site. Obstructions varied in depth from 1 – 4m, ranging from large redundant reinforced concrete bases to a brick culvert system which covered approx. 500m2 of the site. These were all removed successfully with no reported refusals for the VSC which covered 1,700m2. With over 1,200m3 of hazardous and 3,000m3 of non-hazardous excavated material to dispose of, on-site stockpiling strategies needed to be followed strictly on a live site where space was at a premium. All the above co-ordinated with the diversion of over 1,000m of existing services.

With a tight milestone programme in place, Jennings were successful in the handover of the Extension ground floor slabs which were cast in the thick of winter adding difficulty to the build. The overseas arrival of equipment to be housed within the Reactor and Sorting Hall was dependant on the ground floor slabs being in place with sufficient curing time.

A new surface water drainage network was installed, including a ‘back up’ attenuation system, to suit the proposed extension layout along with the reconfiguration of over 3,000m2 of reinforced concrete hardstanding. All this while maintaining the fluidity of the operations team operating the waste to energy plant.

With our motivated and expert level team, industry knowledge and vast experience, Jennings were able to complete the project in line with milestones set in the contract. Ultimately, to the satisfaction of our Client.

We’d like to thank Orsted for this valued opportunity to work for them once again.

RAF Valley March Safety Award

The March safety award goes to two operatives from Jennings, Rhidian and Harry.

Recipients of the March Safety Award – Rhidian (left) and Harry (right)

Rhidian is recognised for his banksmans role during a very difficult excavation and install from the main electrical sub station on the base to the new medical centre during which time many services known and unknown were uncovered and crossed without any damage. It goes without saying how important it is to ensure live services are not damaged and particularly difficult when they are unknown and even more so when working on an operational air base so well done Rhidian (and also thankyou to absent excavator drivers). Rhidian, as a young person at the start of his career, displays an excellent attitude to safety and hopefully he will take this with him as he progresses.

Harry is recognised and thanked as the most improved for his efforts in maintaining a good health and safety attitude during his time on a Galliford site. Not once have I had to ask him to put on PPE both task specific and general which can become quite a headache at times and distracting from other issues managers have to deal with. Once again many thanks.

Welsh Youth Flying Fishing Team Support

Jennings supported the Welsh Youth Fly Fishing Team, contributing to the £1400 raised in aid of their 2018 International. Jennings is pleased to receive their letter of thanks shown below.

Warm Weather Helps Progress of Ardda Leats

Ardda Leats RefurbishmentThe recent dry spell has come at the right time to help the site team progress the refurbishment of the Ardda Leats for Innogy Renewables UK at Dolgarrog Power Station on the edge of the Snowdonia National Park. The 3 year project is in its 2nd year and is carried out during a series of outages to maintain the power station generation. A Flexcrete product is being installed over a light reinforcement mesh to refurbish 2,500 metres of trapezoidal leats which are approx. 1,100 feet above sea level making the project a logistical challenge.
