Lambourn East LD-36
Property Level Flood Protection Scheme
2019 – 2021
Some 21 properties in various areas of Lambourn were identified by Environment Agency & managed by West Berkshire Council Team to be at risk of flooding.
Client – West Berkshire Council
Following a competitive tendering process Flash Flood Doors Limited was successful in securing the contract under the terms of Joint Contracts Tribunal Minor Works Building Contract 2016 (MW 2016) to provide a full flood mitigation solution for each property including a grade II listed building.
West Berkshire Council commissioned Property Flood Resilience Survey carried out by JBA consulting, combined with Quality Submissions and priced bill of quantities formed the bases of tendering process.
In January 2020 a pre contract meeting was arranged with the client’s representative during which we discussed, fabrication survey delivery program submitted at tender stage, flood mitigation product options, alternative cost effective solutions, quality customer contact and start date.To accommodate the customers who could not be at the property during the weekdays, Flash Flood Doors Limited, arranged to works 7 days a weeks and late hours.
During the fabrication survey properties were added to the list, which had not been surveyed by JBA, we used the JBA format as a base to complete the additional fabrication surveys.
Fabrication survey appointments were also used to re investigate the causes and routes of flooding, which was then used to reassess mitigation measures and recommend more targeted measures.
We sourced and supplied double the quantity of pumps supplying not only dewatering but puddle sucker pumps, the property owners were informed that pumping ground water through open excavated unsealed sumps and pumping into surface water or foul water drainage would in a long run exacerbate the existing sewage flow problem.
Upon completion of fabrication survey and homeowner consultations, our findings and proposed mitigation measures tailored for each property, were sent to the client’s representative, having received his approval in early March we programmed the work on the basis of product lead time.
Work commenced early March 2020, we were then faced with COVID-19 lockdown, by the end of March our onsite work ceased for H & S evaluation.
Having reprogrammed the work, site activities resumed early July. The new Health & Safety rules combined with slow and safe working practices did not delay our end of July, 95% practical completion, with the remainder in abeyance until the resolution of Grade II listed building planning issues and one venerable homeowners safety concerns, to allow us on the property to complete the work.
Despite the unprecedented difficulties, our team worked very hard to provide a quality solution in the shortest time possible and managed to keep the increase to budget set at pre contract stage to approximately 5% in real terms. This was primarily due to COVID-19 effects on the project.
Property Level Resilience (PLR) for Somerset 2018-2019
Some 19 properties in various areas of Somerset were identified by Somerset County Council’s (SCC) Flood and Water Risk Management (FWRM) Team to be at risk of flooding.

Following the customer’s & client’s acceptance of the solutions, a program of works was drawn up, however due to requirements of planning for Grade II listed building status of some properties the work had to be done in two phases.
The mitigation measures, ranged from supply & installation of our PAS 1188-1 2014 BSI Kitemarked single and French doors, supply of crated submersible/puddle sucker pump kits for self deployment, Automatic air brick protection, disabled access ramp, flood boards/gates.

Following completion of work on each property the homeowner/Tenant received a bespoke document pack containing full product information, maintenance procedure user manual and guarantee certificates for the mitigation measures installed at their property.
In order to ensure all customers are treated equally and can use the information pack, we have our documents translated and on this project, we were delighted to help a homeowner with vision problem by supplying our user manual/ maintenance handbook in braile.
Following receipt of consent from the planning authority in May 2019 Phase II works commenced with a second survey carried out on 21st May 2019, and was completed in three site visits, two of which had to be programmed for Sunday work, as risks of totally blocking the entrance to the commercial properties during the workdays could not be mitigated.
