A renovation of an existing office building underneath the A40 Westway road next to Ladbroke Grove Station. The redevelopment will create a retail unit at ground floor level on the high street and a school at first floor level. The works include installation of new curtain walling, alterations to provide more space and light from the glazed elevations and making the existing structural elements safe. Lyons O’Neill were appointed to provide a design up to tender stage and have since acted as a checking engineer to ensure the final design is satisfactory to our client. Prior to the change of use design, LON performed a detailed assessment of the existing structure which included concrete scanning and intrusive geotechnical investigations as well as calculations and 3D modelling to gain a sound understanding of the existing building. At the time of writing, the existing cladding has been removed with new steelwork for the portalised frames and ceiling supports are being installed and mullions for the curtain walls are being fixed.
We are currently working on a scheme for a new 5 storey mixed use office and workshop development in Wimbledon. Working with the Architect we are researching different construction techniques to achieve a robust yet economical structure. The structure will be highly exposed integrating the structural elements with the architecture. Our challenge is to combine practical construction methods with industrial and robust finishes.
This project required some integrated temporary works and clear understanding of the building process. The rear two storey structure in the rear elevation was required to hover above the glass rear extension. We achieved this by using the mass of the main structure and cantilevering two steel beams out to pick it up. By inserting a new raft below the building, we were able to redistribute loads evenly eliminating any differential movement.
Lyons O’Neill have been involved in providing pre-planning reports for a number of years. Our high level of geotechnical support and experience in basement building techniques means we are able to advise Architects and Clients on the most cost effective solutions and how to maximise space. Through illustration of the build sequence we are able to convey complex structural issues and engage the rest of the team in the planning process. In addition to Construction Method Statements and Basement Impact Assessments Lyons O’Neill are able to provide Traffic Management Plans so the Client has one stop shop for the pre planning input.
As one of the UK’s largest installers of photovoltaic cells, Solarcentury have sought to develop standard fitting systems for a variety of roof types. We have worked closely with them since 2000 working on various prototypes and installed systems. We have also worked with a number of manufacturers doing research and development to prepare their products for the UK market.
Lyons O’Neill are a team of professionals with the necessary skills and experience to champion the use of SuDS within the overall design of the development from an early stage. The civil engineering team are capable of understanding the site’s particular surface water management needs and opportunities. We have the knowledge and experience in using SuDS-based solutions to influence the holistic design of a development’s drainage system. Detailed below ground drainage design (3D modelling) Management of CCTV drainage surveys Pre-development enquiry for capacity checks Preliminary foul and surface water drainage design for master planning Foul and surface water pumping stations Drainage strategy reports / surface water management plans for planning Advice on the requirements of sustainable urban drainage systems (SuDS) Soakaway design to BRE 365 Environmental discharge permits LLFA SuDS pro-forma Hydraulic design calculations within Micro Drainage Designs compliant to Sewers for Adoption 7th Edition Provide section agreement applications required under the Water Industry Act 1991: Pre-development enquiry / capacity checks Feasibility study (detailed appraisal) S106 (connect to a public sewer) S104 (adoption of a new sewer) S98 (requisition of a public sewer) S185 (sewer diversion) S102 (adoption of a public sewer)
With our experience in refurbishments and understanding of the building process we are increasingly working as Party Wall Engineers for a number of Surveyors. With our pragmatic and robust approach to the realities of the building process we have been able to negotiate and resolve a number of complex site boundary issues for a range of Clients including the Lyric Theatre, Hammersmith.
Our ability to design appropriate solutions is underlined by our technical expertise of a range of construction materials, both traditional and modern. Our in depth knowledge of structural timber and engineered timber such as cross laminated timber (CLT) and glulam; allows us to efficiently utilise the material on projects, exposing its full potential as a sustainable structural solution. We provide specialist timber advice to timber contractors, main contractors and directly to homeowners. Our early involvement in projects has resulted in efficient and elegant designed structures, with a degree of certainty thus reducing any risk of design changes at a later stage.
Lyons O’Neill have had a lot of experience in complex bespoke structures. We have completed a number of projects which involve complex geometry and new techniques. The need for prototyping in these scenarios has played an invaluable role and our understanding of the process has helped us to complete a number of successful.
