Museum of London - Visionary RoofSynopsisThe Museum of London opened in 1976 on the historic London Wall and is a few minutes’ walk from St Paul’s Cathedral. A visionary approach to roofing had been adopted on a building that, will not only green as much of the exposed roofs as possible, but also provide a strong research aspect for future green roof projects. As with many buildings, the original roofs needed to be upgraded or replaced, at the same time as being brought up to date using environmental and sustainable solutions.Through the recommendation of waterproofing and green roof manufacturer Bauder Ltd, the Museum invited Dusty Gedge, one of the UK’s leading independent green roof consultants, to work directly with them to design 3500m² of varying habitats that encompassed the museum’s sustainable vision. and help in the provision of environments that would attract a range of wildlife, as well as being able to help the city adapt to climate change.Bauder Building BoardProject:Visionary roof, Muesum of LondonLocation:LondonProject type:RefurbishmentRoof size:9512m²Specifier:Museum of LondonRoofing contractor:Russell Trew LtdThe specificationAn independent consultant had previously carried out an energy model on the Museum of London buildings. When the museum inputted the green roof specification, it showed a potential energy saving of 10% per year, as well as a reduction on the future replacement costs of the heating and cooling plant. Some of the green roofs were funded through Drain London, a partnership project led by the Greater London Authority and funded by Defra. The project aims to better understand surface water flood risk across London, with a view to promote interventions (such as green roofs) to reduce surface water flooding. The museum has used the Bauder green roof system and worked closely with Dan Costen of Bauder and the roofing contractor Russell Trew Ltd, to deliver the various green roof spaces.These include:The refurbishment of the lower garden in the central courtyard with hard landscapingThe installation of Bauder’s new wildflower blanket to the upper garden in the central courtyard (funded through Drain London)Plug planting the roofs of the recently completed garden and terrace rooms that provide high quality corporate hire (matching the colour scheme chosen for the rotunda garden refurbishment and integrated with the new rainwater harvesting system funded by Renaissance London)An integrated sustainable urban drainage system (SuDS)Plug planting in other individual small roof areas including outside the boardroom and committee roomsTwo different planting schemes on an area of the main museum roof where the Drain London Project aims to carry out water attenuation researchThe resultRetrofitting green roofs will help to realise the Mayor of London’s ambition, to increase green cover in central London by 5% by 2030. The Museum of London is one of the largest retrofit green roof projects in the City and is certainly to be commended for allowing its roofs to be used for research purposes. Not only will it provide a benchmark for best practice, but it also demonstrates that retrofitting green roofs onto existing buildings is both environmentally and economically viable and is the way forward in helping London adapt to climate change.System installedBauderflex Green 1 BauderPLANT E 42A torch applied SBS elastomeric bitumen capping sheet.

In this case as the museum building had already been energy modelled by outside consultants, it was decided to input the green roof specification into the model. The results showed a potential energy saving of 10% per year, as well as a reduction in future replacement costs for heating and cooling plant. These factors, combined with the longer life cycle replacement of green roofs compared with normal felt roofing systems, enabled me to produce a robust business case for green roofs. With increasing energy prices the economic benefits of installing green roofs can only become more viable”Dusty Gedge added:“One of the major issues that London faces is flash floods during the summer, when sudden rainfall levels overwhelm the current drainage network. With the support of Drain London we will be researching the rainwater run-off for different green roofs. This will help us validate the kind of roofs and depth of substrates that will negate the costly effects that the sudden rainfall has on the infrastructure of the City.”

Whitburn Partnership Centre was designed by Project Architects, Matthew Fair, Neil Forrester and Jamie Bateman at Smith Scott Mullan Associates for West Lothian Council. The design of the contemporary £4M building restores the historic Whitburn Burgh Hall original façade as it is one of the towns most renowned buildings and incorporates a new-build two-storey extension.Located in the centre of Whitburn, this building is a community hub that embraces the West Lothian Council’s model of bringing together services that benefit local communities whilst delivering financial efficiencies through the decrease of council buildings. This building facilitates a library, community halls, museum and customer information service office, making it an important community resource. Project:Whitburn Partnership CentreProject type:New buildLocation:West Lothian, Scotland,Waterproofing:Bauder Total Roof System (BTRS)Roof size: 525m2Energy generated from PV array: 10.35kWp Specifier: Smith Scott Mullan AssociatesMain Contractor: Maxi ConstructionApproved contractor: ProCladd (Scotland) LimitedSolar PV installer: Intelligent Electrical SolutionsThe specificationTo support the West Lothian Council's sustainability objectives of achieving high energy efficiency, it was our responsibility to specify a waterproofing system and provide a solution for natural energy generation. The bituminous Bauder Total Roof System (BTRS) was chosen for this project as it features membranes that can withstand impact and tearing, as well as thermal insulation that met the required U-value of 0.15 W/m²K. This waterproofing system is verified by the BBA and offers a service life in excess of 35 years.The BauderSOLAR system was also specified, as it incorporates photovoltaic arrays for natural energy generation. The photovoltaic mounting system is attached to the roof without penetration of waterproofing or the deck, safeguarding the integrity of the waterproofing to fulfil its full-service life.Project challengesThe Architect’s design incorporated unusually high parapet upstands, which posed a challenge for installers. Area technical manager for Bauder, Christopher Langton, attended design meetings with the Architects and Main Contractor to discuss the best solution for installation. A mutual agreement was made for the underlayer to be mechanically fixed to prevent any slippage of the capping sheet membrane. Due to the height of the upstand, non-combustible insulation BauderROCK was incorporated into the design at these details.The installation of BauderSOLAR F uses prefabricated bituminous BauderK5K membrane sleeves to slip over the mounting plates and welded into position, anchoring the plates to the surface of the Bauder waterproofing system. Approved BauderSOLAR installers, Intelligent Electrical Solutions, installed the BauderSOLAR system, collaborating with ProCladd, approved contractor for the waterproofing installation, and other trades during the roof installation.There is a junction where the flat roof meets the original slate roof of the adjacent building, this detail fell under the torch free zone that hot air welding techniques are used to install the membranes within these areas.The resultInstallation of the Bauder waterproofing system may only be carried out by trained and certified operatives approved by Bauder. A project pre-start meeting was held by Bauder site technician, Duncan Hastings, and area technical manager, Christopher Langton inviting the Site Manager from Procladd and their Bauder badged operatives. During this meeting, they discussed the installation of the project, and identified the areas that required torch-free and torch-safe detailing. They also discussed how the project was going to be delivered in co-ordination with other trades working on the site at the same time, for example cladding and lead that was installed atop the waterproofing upstand details.Weekly site-inspections were carried out by Bauder site technician, Duncan Hastings during the project. Visiting the site frequently meant that Duncan could provide consistent support to the installers and answer any questions they may have had directly. It also meant that the quality of the roof installation was being monitored regularly to ensure it would be to a high standard, achieving the comprehensive guarantee.The approach taken to deliver this project on time and to budget was through meticulous planning and working to tight time frames. The organisation of the delivery of Bauder products to site had to be in line with the schedule to ensure that the site was ready to receive a delivery. With the project located in the busy centre of Whitburn next to a cross junction with traffic lights. This meant that timed delivery of products to site was required in addition to prebooked off-loading by pump truck and tail lift or by telehandler.Health, safety and environment was managed during the planning, design and installation of this project by advising that all installers follow the advice shown in the “Responsible Specification Checklist” produced by the National Federation of Roofing Contractors.In accordance with the Workplace (Health, Safety and Welfare) Regulations 1992, roof edge protection in the form of scaffolding was installed during installation. The project’s perimeters were surrounded by Heras fencing to isolate the construction site from the public. All scaffolds that were on the elevation next to the public had toe boarding and safety mesh where required.As standard, there was a one-hour Firewatch after the Bauder membranes have been installed using a gas torch. This was carried out by Procladd operatives each day when they were working on the project to ensure the welfare of the workforce, and the safety of other trades and that of the building. The 19kg gas cylinders were used on this project as they are easily transportable on the roof area. At the end of each working day, the cylinders were stored in a locked and designated gas storage unit on site.System installedBauder Total Roof System (BTRS)1 BauderK5KElastomeric bitumen torch-on capping sheet in charcoal grey.

Chelmsley Wood Shopping CentreBauderflex bituminous waterproofing systemSynopsisChelmsley Wood Shopping Centre, located in East Birmingham, was experiencing leaks with their current flat roof waterproofing system and so they needed a quick, high quality solution to remedy the situation. Although competitors had suggested the only option was to strip the roof, Bauder found a more cost-effective answer by using our in house Troxler Moisture Gauge to identify any areas of wet roof construction, removing the saturated areas and then overlaying the whole roof area.Bauder Building BoardProject:Chelmsley Wood Shopping Centre Location:BirminghamProject Type:RefurbishmentRoof Area:4500m²Specifier:Black Cat ConsultancyApproved Contractor:BBR Roofing LtdProject challengesThe works were to be undertaken in the middle of winter on the existing single ply covering which kept freezing when the operatives were drying the surface. Fixing down of the insulation boards (to the existing waterproof covering) was a noisy operation which also exposed the retail tenant below to risk of water ingress. Work had to be undertaken on a roof where ridges and valleys had to be navigated whilst managing the waterflow.The specification allowed for the removal and replacement of the saturated areas as identified by our moisture mapping survey. This operation had to be planned to ensure that the retail stores were not put at risk in terms of water ingress, but still managed to keep the works progressing to schedule. This was particularly difficult due to the exposed site and the inclement weather encountered. The resultAs a result, Large sections of cable bespoke design had to be developed with Bauder to overcome these challenging site details without the need to decant the retail tenants below. trays and handrails had to be lifted in situ so the roof works could be completed without compromising electrical or mechanical install.By working closely with the centre, a method of work was developed which fulfilled these criteria in terms of waterproofing, health and safety and business protection of the shopping centre. System installedBauderflex bituminous waterproofing system1 BauderFLEX K4EA torch applied SBS elastomeric bitumen capping sheet, featuring spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture.2 BauderTEC Sprint DUOA self-adhesive elastomeric bitumen underlayer with DUO lap technology.

The waterproofing on the roof of their Sheffield manufacturing facility had exceeded its serviceable life and the main-substructure was extremely corroded leaving it unstable and requiring urgent remedial work.

A number of the building’s roofs at Roundwood Park School needed refurbishing to prevent further water ingress entering the classrooms below. The client wanted the new waterproofing system to be of high quality and provide falls to the roof to help mitigate ponding water. A no capital outlay PV solution and new rooflights were also desired as part of the works to optimise the roofs functionality. The school remained open throughout the project creating logistical challenges.

Lagg Distillery, located on the Isle of Arran in Scotland, is a new build whiskey distillery which opened its doors to the public for the first time in the autumn of 2019. The client was eager to create an iconic landmark and echo the contours of Arran with a roof scape that would blend into the environment.

A notable feature on the University of Manchester campus is the Samuel Alexander Building - a five storey Grade II listed building. Erected in 1919 the building has been excellently conserved, however one element that required urgent attention was its flat roof, which had been experiencing considerable water ingress.

The roof area was badly damaged by heavy storms, with all existing ballasted solar panels lifting off the single ply roof and destroyed beyond repair. The client needed the remedial work completed to fixed deadlines in order to comply with insurance requirements, and wanted to optimise the roof by replacing the pre-existing photovoltaic (PV) array with a solar solution that would deliver superior energy generation. The office also had to remain operational throughout the works, creating logistical challenges

Sheringham High School is a secondary school with academy status located in Norfolk that underwent significant refurbishment to repair a number of its failing roofs. The client wanted the school’s campus to act as a benchmark for sustainability and therefore saw this as the perfect opportunity to achieve this with the addition of solar panels.

The original waterproofing on the Maternity Hospital roof had exceeded its serviceable life and begun experiencing water ingress, requiring urgent remedial work. Bristol City Council wanted to optimise the roof area by installing a high quality, long lasting PV array that would contribute to its Solar City scheme that aims to provide one gigawatt of solar power to Bristol by 2020. The installation needed to cause minimal disruption to ongoing work at the hospital and insulation upgrades were necessary to ensure the roof achieved the required 0.25 U-Value.

A brand new school on the outskirts of Bury St. Edmunds in Suffolk was built to accommodate 1,600 students. The project was designed and managed by Concertus Design & Property Consultants on behalf of Suffolk County Council, who wanted the school to act as a benchmark for sustainability with the building’s roofs playing an integral part in achieving this through the inclusion of solar panels.

JCB’s World HQ in Rocester recently completed a major project to improve the integrity of its main office roof, and took the opportunity to reduce the company’s overall environmental impact through the addition of a state-of-the-art photovoltaic system at the same time.

Set within the Garscbue Estate, Archial Group, the Architect, wanted a new build project with as minimal visual impact as possible, so the building was constructed within the side of a hill with a green roof. Towards the end of the roof’s construction a seeded grass finish was opted for.

The architectural vision for this new build was to create a modern learning environment that would add value to the local community. The building consists of eight roof areas on a variety of different pitches totalling 3,400m². Aesthetics were also important to the client as most of the roof areas are pitched at a 20° slope making them highly visible, particularly from the central courtyard area.

The award winning Noah’s Ark Children’s Hospice currently supports over 160 children who are seriously unwell, 230 of their siblings and 350 of their parents/guardians by providing holistic, bespoke care. To facilitate the care of even more children and their families and care givers, a new building was needed. Main build partners, 8build, undertake one charitable build project every year and were therefore recommended for the Ark project. Their unique collaborative approach and utilisation of supply chain relationships kept project costs low with these costs savings directly benefitting the hospice as they could then be spent on care for the children. The project won the "Roof Gardens/ Living Wall Installations - Commercial Roof Garden or Podium Landscaping - Under £500k" award in the BALI National Landscape Awards 2020.

Situated in the picturesque village of Tintern in Monmouthshire, the Cistercian abbey is one of the most historic monastic ruins in Wales. In 2013 work started at the abbey to replace the roof of the gift shop, which had exceeded its serviceable life. The brief for this project was to not only repair the failing roof, but to bring the abbey to the forefront of modern-day roofing technology with the installation of a state-of-the-art photovoltaic (PV) system. Given these requirements, BauderSOLAR’s innovative PV solution, SOLfixx Plus, was a natural choice.
