Presentations & Public Speaking
This is a variation of a presentation that we did at the ABX Show in Boston. It covers the key concepts, benefits and drawbacks of modular construction. It also includes several illustrations and examples.

Overview of Modular Construction
- 1 What type of construction process are we talking about ? Why is this a hot topic? What are the considerations to adoption? What are the critical success factors? Rusty Williams, Business Development Triumph Modular Inc. CRITICAL SUCCESS FACTORS FOR MODULAR CONSTRUCTION
- 2 The Cocktail Conversation Challenge What is it that YOU do?
- 3 The Cocktail Conversation Challenge
- 4 Oh, Interesting…. Is that like... Uh…
- 5 Some thoughts that may come to mind… Tiny Houses Kit Stackable Modular Containers Kit Panelized
- 6 Which is good…. Because they have a general idea And bad….. Because it’s confusing
- Prefab is an Umbrella Term = Prefabrication = Factory-built = Off-site Construction Tiny Houses Stackable Modular Containers Kit Panelized They’re all “prefab”

- 10 What Triumph Does Best Volumetric Modular 6 sided building blocks Built Off-Site in a controlled manufacturing environment. Near-Complete: typically over 65% complete. Accelerated: Most accelerated process known, with the promise of no sacrifice to quality or design.

- Growing Worldwide
- 14 Why Choose Modular?
- 15 21st Century Buildings Need to be Designed with Change in Mind Modular is Flexible Construction Image by Victor Enrich.
- 16 Data from Industry- wide Case Studies
- Fast Without sacrifices to design or quality 66% projects reporting 35% to 50% faster than conventional Modular Allows For Concurrent Processes
- Less Disruptive On site just weeks Not years
- Cases from the Off-Site Studies Report demonstrate an average of 16% cost savings compared to traditional construction. Greater control of cost Reduction in change orders “8% cost overruns over multiple projects over a four year period due to Change Orders.” Predictable Cost 19 “The reason for choosing off-site construction is not simply in cost efficiency, but in precision of the construction and ability to control and predict cost.” (NIBS Off Site 2014)
- Safer According to the Safety Management in the Construction Industry SmartMarket Report, "Firms using prefabrication … have significantly higher adoption levels of nearly all the safety practices measured in the survey.”

- 23 Approaching Modular as a Specialized Technique / Style
- Designed to Fit Together Computing = Application Programming Interface Modular = Architecturally Planned Interface
- Connecting Components Tested before Arriving
- Working Within Limitations Transport restrictions limit module size. Less plenum space. Larger beams needed to create clearspans reduce ceiling height.
- Critical Success Factors Commit to the concept early, owner and consults Speed requires intense coordination - Design build or construction management forms of contracting Team member roles clearly understood, designer, factory, engineers. Subcontractor Scopes of Work clear Architect works in close coordination with modular expert - pull subs up into design process 27
- 28 Owner Fabricator Architect Subcontractors Close Coordination / Collaboration
- 29 Fabricator Selection Factory vs Field Transportation Permitting and Regulatory Other important considerations:

Editor's Notes
- Distant Cousin Challenge: What is it you do?
- Distant Cousin Challenge: What is it you do?
- Distant Cousin Challenge: What is it you do?
- Helped by trendiness and coverage in Dwell, Inhabitat and HGTV’s Tiny House show.
- While these are the same discipline – prefabricated buildings – they are very distinct styles and techniques.
- Many modular companies will use legos as a comparison. It’s appropriate because they click together to build amazing things. But for Volumetric, you need to imagine fully finished living spaces inside each lego. That’s what we do: move-in ready legos.
- Luckily with a few pictures and one video it’s easier to convey.
- We’ll get into some tangible metric in a minute, but at a higher level there’s a growing need to think of space as a flexible asset – able to adapt to changing needs. In fact Google referred to this as a “reconfigurable campus”
- 60 companies interviewed. 17 Case studies All attendees of this webinar were sent the link to the “NIBS” report, National Institute of Building Sciences and the University of Utah. A year long study completed in April 2015. Over 66 companies interviewed by 8 researchers, 312 total survey respondents, 17 case studies nationwide. It was an important study the first of its kind undertaken by objective outside observers, Triumph was one of 9 sponsors of the report. The introduction on Page 5 cites : “Although conceptually strong .. The lack of research data on PMC has been identified as a barrier to its adoption” The study’s conclusions are overall favorable however there is one major theme or take away that corroborates what many of us practitioners have been experiencing as the largest limitation of permanent modular – that is, its requirement of so much collaboration up front. Procurement methods that learn toward driving the lowest cost and competion rather than collaborative methods of team formation and contracting – are a large barrier.
- Key consideration for educational institutions, tech companies, and buildings designed for relocation or “temporarily permanent” use – 5 to 15 years.
- Point to the slide Of course that is a part of what we are trying to do here today. The process is unique the process is different. Parties who are steeped in tradition of conventional ways of thinking will need to rethink – on that note let’s look at our first video.
- Design Assistance - Prior experience required. The Module Layout is factored in to the design, Module layout creates the most logical and cost effective way to achieve the desired outcome Module layout dictates design of the Foundation Controls routing based on dimensional limitations Access to and around the site – staging areas Mechanical designs – ceiling spaces Configuration to maximize construction off site. Final Design and Approvals are more time sensitive. Project schedules should establish a reasonable but finite time for final design development and decision making Decisions must be made early and modular footprint frozen Turnaround time for approvals is shorter Changes during fabrication are costly and can be avoided with more collaboration between stakeholders. Define and Delineate the Project Scope of Work During pre-bid phase establish a scope of work document that best suits the requirements of the stakeholders Clearly communicate to avoid scope creep/overlap or scope gaps
- Triumph is specialized GC with extensive experience coordinating modular projects with fabricators, architects, owners and subcontractors.
