Presentation Outlines and Speaker Bios
1/ Why the full opportunities of off‐site construction have not yet been realized: Mark Taylor, Vice President, Permanent Modular Construction, PCL, Toronto, Ontario
Description: Significant opportunities exist to increase prefabrication in the construction industry. Currently, prefabricated components are primarily seen at the extremes of the construction process. Individual trades are prefabricating more of their work, while there is also a whole industry focused on full modular building solutions. The greatest opportunity for the wood industry lies between these sectors, however better exploiting this
middle ground will require a shift in the traditional construction logic, process, and contractual arrangements. Case studies will demonstrate some of PCL’s own ventures into prefabrication. They will discuss the benefits realized, lessons learned, and some of the requirements to successfully integrate prefabrication into a project. The implications of these opportunities for the wood industry will be discussed, with the speaker giving his personal vision of the future of the construction industry, and how off‐site fabrication will create a quantum leap forward for the industry. Outcomes: A better understanding of off‐site fabrication and where it can best be applied; The benefits of off‐site fabrication; Opportunities for the wood industry to increase its value proposition through more prefabrication; How increasing off‐site fabrication will change the construction industry. Bio: As vice president, Permanent Modular Construction, Mark Taylor's mandate is to maximize the level of modularization and prefabrication on PCL's projects. Having been with the organization since 1997, he has a strong hands‐ on construction background, serving in various capacities in PCL’s operations in Alberta, British Columbia, and Ontario. Primarily focused on the buildings sector, he has also worked in the civil, residential, and renewable energy markets. Mark holds a P.Eng in civil engineering from the University of Nottingham, England, is a registered professional engineer in Alberta and is a Canadian Construction Association (CCA) Gold Seal certified project manager. 2/ Off‐site Construction from a Manufacturer's Viewpoint: Lorne Derksen, President, Alliance Truss Group, Surrey, BC and Brian Woudstra, B.Sc.Eng., Pre‐Construction Engineer, StructureCraft Builders, Delta, BC Description: Tremendous opportunities exist for off‐ site construction to fundamentally change design, assembly, quality and costing parameters for wood frame structures. Current wood frame practices – design and assembly – are in their infancy with significant opportunities and challenges. Lorne Derksen of Alliance will show how incorporating trades and into more complex panelized systems can enhance many aspects of a building. As well, limitations in both design skills, tools and common standards limit achievement of the full potential for wood frame prefabrication.
Outcomes: Understand the current level of off‐site construction practices; Learn what possibilities exist for larger and more complex wall systems; Learn what skills and tools are available and essential for successful off‐site construction design; Understand what changes should be made which will expand economic and performance potential as well as increase capacity.
Lorne Derksen Bio: Lorne began his career in construction supply as an account representative for Hollyburn Lumber Company in 1992. By 2000, having pursued sales in Germany, Japan, the U.S. and local truss manufacturers, the company increased sales by over 25 per cent in one of the worst years for construction starts in a decade. In 2002, Lorne became vice president of business development and an integral part of Valley Truss, a local truss manufacturer whereupon. He created a wall panel division; selling, designing, and setting up the manufacturing processes for their first wood frame apartment project in the U.S. Within two years he managed the supply of over 500 units of apartments with wall panels, trusses and engineered floor systems in the U.S. In 2004 he spearheaded wall panel supply in the Vancouver market, and in 2005 initiated the creation of an
affiliated framing company, Nuframe, to provide a complete wood frame structural solution; an industry first. In 2009 the two compnies merged into one of the largest woodframe building component manufacturers in British Columbia. In 2013 the company integrated Maple Ridge Truss into the Alliance Group of Companies, creating the largest truss and wall manufacturer/framing service/structural engineering group in BC with more than 100 employees.
Brian Woudstra Bio: After gaining reinforced concrete engineering experience and working overseas in East Africa, Brian joined StructureCraft Builders in 1998 as a project manager and engineer. While continuing to design buildings in concrete, steel and wood, he managed all StructureCraft projects from 1998 through 2002, including the Surrey Central City project. He has carried out structural design for several complex timber structures (e.g. Central City Atrium Roof, 36, 000 sq.ft.) and has gained extensive experience in timber design, connection engineering, cost estimating, structural detailing, shop drawing review, and procurement of special materials such as castings, cables and
coatings. He liaises with clients, architects, engineers, general contractors and suppliers. Brian is involved in all aspects of each project including material selection, member sizing, connector types, coating systems, casting design, specialty procurement, structural modeling, 3D renderings, budget and shop drawing reviews. If Brian is not in the office, he is often found wandering through the shop, smelling the sawdust and touring groups of visiting clients.
3/ U.K. Experience in Mid‐Rise Solid Timber Buildings: Liam Dewar, Director, Eurban Limited, London, England
Description: Solid (mass) timber construction is increasingly the construction method of choice for mid‐rise residential building projects in the U.K.. There are many reasons for this, not least an acceptance that solid timber construction is an economically viable and environmentally preferable alternative to concrete and steel. Whilst familiarity of the construction method, effective procurement strategies, and economic factors have all served to build the market, there is still much to learn as
only a few organizations have actually delivered buildings of this scale. Over the last few years, Eurban has been involved in the design and construction of numerous mid‐rise solid timber residential projects including the U.K.’s largest social housing project, the U.K.’s largest open market housing project and the U.K.’s largest student housing project. By focusing on such ground‐breaking projects and the challenges faced by those involved in their design and delivery, this presentation aims to pass on some of the lessons learned to those involved or looking to become involved in the design, procurement and delivery of mid‐rise solid timber buildings in North America. Outcomes: Understand the unique position of solid timber construction within the U.K. construction industry and why it is increasingly being used for mid‐rise buildings within inner‐city developments; Understand the role of a CLT designer / specialist contractor on mid‐rise solid timber building projects and how experience can inform design decisions and help deliver such projects effectively and safely; Understand the risks associated with the design and delivery of mid‐rise solid timber buildings and how one might overcome such risks; Understand how solid timber construction differs from timber frame and concrete, particularly in terms of fire, and how one might design for fire, both in terms of fire during construction and fire during use. Bio: Liam Dewar is a trained architect and director of Eurban Limited, a U.K. consultancy and construction company that specializes in the design, supply and installation of solid timber building structures. Having introduced CLT to the U.K. 10 years ago Eurban have been instrumental in the development of the CLT market in the U.K. having delivered more than half of the U.K.’s CLT buildings to date.
4/ Building Futures and Rethinking Construction: an evolution from site‐built to off‐site construction: Stephen Good, M Arch, ARB, RIAS, RIBA, Chief Executive, Construction Scotland Innovation Centre (CSiC); and formerly with Campbell Construction Group, Glasgow, Scotland
Description: An architect by training, Stephen Good will present an overview of the wood design and construction sector in Scotland showing its evolution from site‐built to off‐site construction. The presentation will explore the key issues, advantages and drivers which lead to the transition and highlight some of the key players and initiatives which support it.
Stephen will also outline some of the supportive activities and organizations which are reshaping the Scottish construction sector, including the newly established Construction Scotland Innovation Centre and will highlight the future local and international opportunities for off‐site construction. Finally, he will showcase several examples of repetitive, large scale and custom‐designed structures including his experience with the off‐site practices used at the Commonwealth Games in Glasgow. Outcomes: Understand the importance of a comprehensive Design for Manufacture & Assembly (DfMA) program and an effective Design Team Contribution; How to ‘Get it right On Site’ – learning how to take
advantage of the obvious and subtle opportunities afforded by off‐site construction; How off‐site construction practices using timber can provide low carbon solutions; Learn the importance of initiating and managing the cultural changes in the design and construction practices which are the key to ensuring delivery of quality and efficiency. Bio: Stephen Good graduated from Strathclyde University with a Masters Degree in Architecture in 1998. Following nine years as an associate with award winning architects Anderson Bell + Christie, Stephen joined CCG (Scotland) Ltd. in 2007 and led the delivery of the groups’ £12m, state‐of‐the‐art off‐site manufacturing base in Glasgow, which opened in 2010 and is regarded as one of the U.K.’s most advanced timber closed panel production facilities. In 2011, Stephen took on the role of Group Design Director with CCG and set up the Building Futures Lab, a specialist sustainability design consultancy providing support to both CCG and external clients, and led the delivery of notable projects including the 2014 Commonwealth Games Athletes Village, BRE’s Home‐ grown Timber/CLT Zero Carbon Visitor Centre and Scotland’s largest scheme of Scottish timber, closed panel off‐site manufactured, certified passivhaus dwellings in Lockerbie. In September 2014, Stephen was appointed chief executive of the Construction Scotland Innovation Centre (CSiC). The CSiC uniquely presents industry with a single entry point to the expertise and resources of 12 Scottish universities and multiple public sector organisations, with a focus on transforming the construction sectors’ approach to and adoption of innovation as a catalyst for growth. Scotland’s forestry and off‐site sectors are key priority areas for CSiC.
5/ A Study of Prefabrication in Timber: DI Michael Schluder, Founder & CEO, Schluder Architecture, Vienna, Austria
Description: Michael Schluder will showcase the development of multi‐storey timber buildings based on the current status of buildings of one to 10‐storeys in an urban setting. He will focus on the design and development of urban buildings using timber as a construction material as part of a culturally interesting, economically relevant and ecologically sustainable and sound urban city planning strategy. Wood construction elements are prefabricated in increasingly larger size, thus allowing for shorter
construction times, and for dry and clean construction sites in the city, which cause only a fractional amount of the noise found at conventional construction sites. Wood construction buildings can be remodeled and altered easily. In case of changing usage requirements they can be modified correspondingly rather easily, which helps extend the expected useful life of the building. And finally, wood, a CO2‐neutral construction material, is capable of retaining CO2, which positively affects the ecological balance of the building –a fact of even increasing importance in the future. Outcomes: Learn about design and construction systems for multi‐storey buildings; See examples of successful prefabrication methods; Learn about construction systems for passive house systems; View examples for hybrid construction methods and the employment of timber‐concrete composite slabs. Bio: Michael Schluder is both an architect and a civil engineer. He studied at the Vienna University of Technology and has been a certified civil engineer since 1991. He has operated his architecture firm in Vienna since 1988 and has been nominated for several awards, including the State Award for Tourism and Architecture Assignments and the State Award for Environment and Energy Technology 2010. He was awarded the Vienna Timber Construction Award for the child‐care centre at Schrebergasse, Vienna. Over the past several years, he has expanded both the knowledge and capabilities of wood use in multi‐storey timber construction including working on an eight storey FFG Research project entitled – “Haus der Zukunft” (“House of the Future”) to develop innovative construction systems for a multi‐storey timber
building and provision of evidence for its feasibility in accordance with the Viennese building code. He teaches at the Institute for Building Construction at his alma mater in Vienna and is Laureate of “WB – Holzbau in der Stadt” (“Residential Buildings – Timber Construction in the City”. In 2012, he completed the first seven‐storey high‐rise residential building made entirely of wood and built in Vienna comprising a total of 71 individual apartments constructed using volumetric elements.
6/ The Renaissance in Finnish Industrialized Timber Construction Methods: Mikko Viljakainen, Managing Director, Finnish Wood Council, Helsinki, Finland
Description: Highly industrialized wood building systems have experienced a renaissance during the last few years in Finland. Use of wood in construction is being promoted by the Finnish government in cooperation with the wood working industry. The objective is to increase the construction of wooden multi‐storey houses. The present fire regulations allow Finns to build wood‐ framed buildings up to eight floors. If performance‐ based fire design is being used, wood‐ framed buildings may be even higher. The sprinkler system is mandatory when wood is used in the load‐bearing structures. After the present fire regulations were published in 2011, there has been rapid growth to build more
wooden multi‐storey houses. During the last few years, the wood construction industry has been developing and introducing to markets several new types of construction techniques with high prefabrication and new types of off‐site construction methods. They include hybrid construction, post and beam construction and volumetric construction systems. All of them are based on engineered wood products such as LVL, GLT and CLT. The new industrialized wood building systems seem to have superior competitiveness in terms of time savings, costs and quality. The assembly time on‐ site is short in comparison with the traditional techniques. Special attention has been paid to keep unfinished structures weather‐ protected during the process. The presentation demonstrates the new off‐site methods in practice and describes and highlights interesting projects that feature innovative applications of wood in contemporary settings. The innovative tenting system incorporates an interior gantry crane which both replaces traditional scaffolding and protects the entire site — workers and materials — from adverse weather conditions. Outcomes: Learn about highly prefabricated and industrialized off‐site wood construction methods; Learn about state‐ of‐ the‐ art on‐site processes and technology including on‐site tent‐technology; Learn about the effect of the new building methods that go into design and engineering; Learn about the impact of new building methods to cost, schedule and quality. Bio: Mikko Viljakainen holds an advanced degree in architecture (1992) and licentiate in technology (1997). Since 2010 Mikko has worked as managing director of the Finnish Wood Council. Previously, he has experience as an architectural designer in architect offices, a special research scientist and a teaching role at the Tampere University of Technology. Since 1999, he has worked for wood working industry associations to promote use of wood. Mikko has an active role in international cooperation relating to processes and projects. He has several confidential posts in the wood working industry and construction industry organizations. Mikko has written some 15 publications about use of wood in construction, some of them being translated into English and Russian. He has also achieved success in international and national architectural design competitions. His currently resides in Helsinki.
