Bitumen Case Study: Whitburn Partnership Centre

Bitumen Case Study: Whitburn Partnership Centre

Bauder Ltd

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.

Blue roof case study: Cambridge University, Department of Civil Engineering

Blue roof case study: Cambridge University, Department of Civil Engineering

Bauder Ltd

This new build project in the centre of Cambridge combines a Sustainable urban Drainage Solution (SuDS) with vegetation and renewable energy in a warm roof construction.The client for the Department of Civil Engineering at Cambridge University, R H Partnership, identified sustainability as being a key driver in the design of the roof, but also sought a single source supplier that could provide a guarantee for both workmanship and products. Bauder’s systems range encompasses products to meet all the sustainability objectives, and with our network of approved contractors carrying out the installation, we could offer the comprehensive guarantee that was required.Bauder Building BoardProject:Cambridge University Department of Engineering​Location:CambridgeRoof Area:1610m²Client:University of CambridgeSpecifier:RH Partnership ArchitectsMain Contractor:SDC LimitedApproved Contractor:Voland LimitedThe specificationTo meet the sustainability criteria set out by the client, the Bauder technical team designed a roof system combining an extensive blue roof, a green roof and a solar PV array. The first and most fundamental element of the roof system though is the waterproofing. Bauder Total Green Roof System (BTGRS) was selected as it provides robust and durable waterproofing with a life span in excess of 35 years, as validated by BBA Certificate 10/4744. The Plant E cap sheet has also been tested by the FLL to ensure long term root-resistance, making it ideal for use in conjunction with the BauderSOLAR G LIGHT system. The BauderSOLAR G LIGHT system is a unique way to combine rooftop vegetation with renewable solar energy. The PV panel mounting boards are held in position using the growing medium as ballast, meaning the waterproofing is not penetrated and therefore compromised. The mounting boards incorporate a water retention feature which allows a small amount of excess rainwater to be stored for short periods of time for the various plant species to feed from. The BauderSOLAR G LIGHT system’s unique mounting system lifts the panels above the vegetation allowing the plant life to grow freely and therefore qualify a greater area of the roof as biodiverse.In addition to the BauderSOLAR G LIGHT system, a blue roof was added to the build-up. Blue roofs are sustainable drainage solutions designed to manage stormwater on a flat roof to reduce water runoff rates and ease flash flooding and standing water in built up areas. The BauderBLUE Roof System attenuates water from a flat roof over a 24-hour period via a restrictive flow outlet. Calculations are carried out to determine the rate at which the water should egress the rooftop. This is determined by the local planning authority and is often set as low as 5-8 litres per second per hectare. With these calculations, Bauder can design each flow restrictorto meet the necessary runoff rate. For the Department of Civil Engineering, the main roof area of 1455.5m² required two flow restrictors, each with flow control holes to ensure the specified discharge rate of 0.77 litres per second was achieved. The maximum depth of water the roof is designed for is the H-max. When the water level reaches H-max, it will drain via the emergency overflow pipe. These overflow pipes are set at the same height as the H-max level. On this project the H-max was calculated to be 99mm. Although an unlikely scenario, this provision for a ‘once-in-a-hundred-years’ storm event will ensure that the structural integrity of the building is always preserved.Project challengesThe roof deck was constructed using a pretensioned concrete plank roof structure. Due to the large span of these planks, the dead load weight to the roof would be restricted. This being a blue roof with green landscaping and PV (a reasonably heavy build up), presented the issue of balancing the need of the roof design and the weight restriction of the supporting structure. To add to this challenging scenario, the pretensioned deck did not provide a completely flat finish. When installing a blue roof, a flat deck with no positive or negative falls is essential, as detailed in the 2018 update of BS 6229 – Flat roofs with continuously supported flexible waterproof coverings. To overcome this onsite challenge,the final deflection of the fully loaded roof was calculated and the concrete deck was screeded to give a flat finish.The resultBauder believes this project to be one of the first of its type in the UK to bring together so many rooftop systems in one space. Project management and clear communication was paramount in order to ensure a smooth installation. The Bauder project team consisted of green roof and solar PV product managers, area technical manager, technical design team, site technicians and approved installers for the waterproofing.With all the different elements being installed, green roof and solar PV product managers worked with our technical team to design the best possible PV array configuration for optimum energy generation whilst also qualifying for the maximum biodiverse area.Bauder site technicians worked closely with Bauder approved contractors, Voland Asphalte Ltd, to ensure works were kept to schedule and that a high quality of workmanship was maintained throughout.To ensure the landscaping is maintained, irrigation was installed by Access Irrigation Ltd. The system, Permadrip Pro, is a drip line irrigation system with anti-syphon design to resist clogging and pressure regulation. Due to the specialist nature of the irrigation system, Access Irrigation Ltd provided a bespoke design service.The result of this network of expertise was a multi-faceted support service for the client, specifier, main contractor and roofing and PV installers. System installed1 BauderPLANT E 42Green, 5mm torch-on root-resistant capping sheet.2 BauderTEC KSA DUOA self-adhesive, elastomeric, bitumen underlayer. This underlayer was used to ensure thorough sealing of lap joints in low temperatures when the roof was installed.3 BauderPIR FA-TETissue-faced flatboard insulation faced on both sides with aluminium foil to provide efficient thermal output.4 Bauder Super AL-ETorch-on air & vapour control layer. Once installed on the concrete pretensioned plank deck, it can act as a temporary waterproofing layer, allowing internal works to be carried out immediately which was a huge advantage on this new build project.

The project was managed by JJ Rhatigan and Company and the roofing element appointed to Priority Roofing and Cladding Ltd. The roof of the main building and the gymnasium required flat roof build-ups to meet the specifications as set out in in SDG 02-05-03 (Acoustic Performance in New Primary & Post Primary School Buildings), while meeting the general performance requirements specified within TGD 021-7 2018 (Minimum Performance Standards of Roof Materials and Finishes). The chosen system had to meet an acoustic performance of 35dB indoor ambient noise level (IANL). It was decided that, despite sports halls having a slightly higher IANL threshold, the 35dB performance criteria would be applied across all areas of the school, with control of reverberation being a key consideration in the gym.Bauder Building BoardProject:Coláiste an ChláirínLocation:County GalwayProject type:New BuildRoof size:8550m²Main contractor:JJ Rhatigan & CompanyApproved contractor:Priority Roofing & Cladding LtdThe specification:The Architect specified that the insulation used in the flat roof system should be non-combustible and achieve a U-value of 0.16Wm²k which actually exceeds the thermal requirements as described in the Irish Building Regulations Technical Guidance Document L for flat roofs in schools.BauderROCK was specified to achieve the thermal and acoustic requirements of the design. As a Euroclass A2-s1,d0 non-combustible material, BauderROCK also provided the specified fire performance. This insulation could be used across all roof areas, with some adaptations for the gym which required additional acoustic performance due to the inherent nature of the space. Acoustic infills were used in the troughs of the perforated metal deck, thus combatting the reverberation of the indoor environment.  Products appliedBauder Thermofol PVCAn integrated single ply waterproofing system, featuring a lightweight, cost effective membrane which offers a pleasing aesthetic finish on a flat roof. This system holds fire classification BROOF(t4) for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs. BauderROCKHigh density mineral wool insulation.Project challengesOne of the challenges of this project was the ambitious schedule. The use of the self-adhesive air and vapour control layer (AVCL) enabled the trades working within the building to progress quickly without being delayed by weather conditions. BauderROCK is relatively quick to install, as was the lightweight single ply waterproofing.  The resultThe project was finished to time and specification with exceptional workmanship from the fixers at Priority Roofing and Cladding and superb collaboration from all parties throughout. The membrane was finished with standing seams to create a statement look. The roof achieved a U-value of 0.15 W/m2k, exceeding the thermal target, and met or exceeded the 35db IANL requirement across the main building and the sports hall.  The thermal performance, which will hold up for decades to come, will also impart energy efficiency benefits that reduce running costs at the school in the long term. Finally, the non-combustible nature of the mineral wool insulation ensured that the build-up met the fire safety specification.  Advocacy Niall Hanley, Contracts Manager at JJ Rhatigan, the project’s main contractor, said:"Coláiste an Chláirín Athnery was a great success and in particular the use of the self-adhesive AVCL in advance of the build-up allowed works to commence immediately internally, which was critical from a programme perspective.” Kevin Ryan, Director at Priority Roofing, explained:"We found the system both practical and efficient to install. The combination of the availability of the products and the technical backup received was superior to any other system that we have worked with.”  Eoin O’Grady, Associate Director at Healy Partners Architects commented:"We are delighted with the overall delivery of the roof build-up and the performance achieved. The PE hall solution to deal with reverberation noise as well as rainfall noise was very successfully managed. We look forward to working with Bauder on future projects.”

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

In 2011 Muse Developments undertook a £107m redevelopment of the site creating space for two new office buildings, seven restaurants and café bars, a 126-room hotel, a modern civic space and a new public space area in between the new buildings.Bauder Building BoardProject:Marischal SquareLocation:AberdeenRoof Area:5,400m²Client:Muse Development & Morgan SindallApproved Contractor:Briggs AmascoThe specificationWith large parts of the new roofing areas being accessible terraces and areas which will experience a significant amount of foot traffic, the Bauder hot melt structural system was a natural choice. The system was combined with hard and soft landscaping to provide the different aspects of the various terraces, stairways, podium decks and rooftops.The Bauder Hot Melt structural waterproofing system is ideally suited as a waterproofing system beneath paved or ballasted surfacing, car parks, podiums, plazas, green roofs and substructures.Project challengesA key challenge for this project was the fact that Muse Developments and Morgan Sindall, who were working jointly on the development, were looking for a single source waterproofing. Bauder proved to be the perfect fit, covering and delivering all elements of the waterproofing systems.The resultApproved contractor Briggs Amasco carried out the works on the 5,400m² of the separate roof areas, whilst expert Bauder site technicians carried out a total of 26 site visits over the duration of the project to ensure the quality of the installations. Following a final inspection, Bauder was able to issue a 20 year product and workmanship guarantee on the project.System installed1 BauderPLANT E 42Green torch-on root-resistant capping sheet.2 790-11Hot melt rubberised bitumen asphalt with a percentage of post-consumer recycled materials that infills and fully bonds to all minor deviations in the deck.3 DeckPrimed concrete.

Noah’s Ark Children’s Hospice

Bauder Ltd

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.
