Drain Mapping Services

Friday, May 29th, 2015

What is drain mapping? Drain mapping is the method by which the layout of drains is established to create a map of the drainage system in a given area or around a certain property. Why might drain mapping be necessary? It’s very important when planning further building in an area. For example, when building an extension to a property the layout and scope of existing drains needs to be established if it isn’t known already. Once this information is gathered, then decisions can be made as to whether the drainage system needs an alteration or an upgrade and where and how to connect the new build to the existing system. Drain mapping is a key part of a drains survey, such as those ordered by house buyers considering the purchase of a property. In some cases their surveyor may insist on one. Major problems to the drains can be very expensive to repair so a knowledge of their condition and layout can be vital. This might be of particular importance in older properties where records of drain positioning might be inaccurate or may not even exist. Drain mapping may also be required when there are problems with the drains such as a major blockage, inefficient operation or leaks. Knowing accurately how the drains are laid out makes fault finding and repair work more effective. This is especially valuable in the case of recurring problems - a more deep seated problem can be revealed once an accurate map of the drains layout is established. Methods of drain mapping The techniques used vary in their complexity: Water flow tracing - Flushing The most straightforward method is when the flow of water is checked at various stages of its route through and out of a property. The test is run by simply running a tap or pouring buckets of water down the drain

LDF wins contract to refit drains on old BBC Headquarters development site!

Thursday, May 14th, 2015

We’re pleased to announce that LDF has been chosen to help refit the old BBC Television Centre in Wood Lane, London, which is to be turned into housing and studios later this year. The team will be working in conjunction with Carey’s, a leading construction and resource recovery group which will also be enlisting the help of Lend Lease and Bovis Homes for this large-scale project. “We will be working predominantly in the TC1 and TC2 areas of the old BBC site, which form a horse-shoe shape close to the entrance to the old Television Centre,” explains Danny Fuller, Managing Director. “We have developed a specialist confined entry space for our staff in the site’s undercroft and are going to have three full-time teams onsite five days a week to ensure the project is completed on time and on budget.” Work will involve the removal and re-fit of all combined foul and surface water pipework located in the undercroft of the former studio buildings. In addition, LDF are responsible for the clean and CCTV Survey of all rainwater pipework to ensure they are given a clean bill of health and in the best condition possible, ready for the big opening. Heavy cast iron pipework will need to be removed by specially trained engineers, and specialist hand cutting equipment will reduce the need for conventional cutting and speed up the delivery process. The team is due to complete the project within a three month timeframe and, upon successful delivery, it’s likely that LDF will be asked to start work on the plumbing requirements for the new developments that are going to be built on the former studio site in late 2015/early 2016. This contract alone is expected to be worth several million pounds. “We’re delighted to be working on the site of the old BBC headquarters
