With the construction industry on the upswing, with 2013
construction starts on the whole advancing 6% to $516.8 billion over the year
prior according to McGraw Hill Construction (a division of McGraw Hill
Financial), attentions are turning to emerging building methodologies,
technology resources and materials that have extreme upside potential and can
positively impact bottom lines.
With this in mind, here are three game-changing advancements
that will significantly impact building and construction concerns in 2014 and
beyond:
1) Cargo Container Construction
With the U.S. new construction industry desperate for ways
to cut costs and provide sustainable solutions without undermining quality,
cargo container construction is a boon–especially for America’s multi-family,
mixed use, and commercial markets that are completely underserved despite
growing demand for this new and novel
building methodology.
The escalating marketplace acceptance of cargo container
construction is being driven by the reported superior cost efficiencies,
heightened profitability, and minimal build time associated with this emerging
building option. It’s estimated that, on average, cargo container construction
is fully half the costs of other building methods. Shipping container-based
construction marries the trend toward sustainable housing solutions with
addressing escalating building costs and the surplus of durable, versatile,
widely available, economical and code-friendly cargo containers that can be
readily repurposed to frame houses, condominiums, dormitories and other
residential, retail, and commercial structures. In addition, these heavy gauge
steel structures only take a fraction of the time to build and are more energy
efficient than their counterparts due of a high-purposed combination of new
technologies used in the design and construction process.
Given the range of benefits and advantages, architects,
contractors, and individuals are increasingly seeking retired shipping
containers to build homes, offices, apartments, schools, dormitories, artists’
studios, emergency shelters and shops. For example, Travelodge completed a
hotel in using cargo container construction methods and finished 6-months early
and 10% under alternative building estimates, saving them approximately
$900,000. Starbucks is also building hundreds of stores across the U.S. using
shipping containers. Real estate developer Three Squared, Inc. has a 20-unit,
four-story condominium complex underway that spans 26,000 square feet and
integrates 93 shipping containers.
2) Building Industry Modeling (BIM) Software
The emerging BIM process allows building designers and
architects to work in “5D”—a 3D model of the project with the 4th and 5th
dimension being the addition of scheduling and cost estimating, respectively.
Using BIM, developers can employ an integrative project
delivery approach to planning and design and bring all members of the
architectural, design, engineering, construction and environmental teams to the
table at the onset of a project. This team can then benefit from a 3D model of
the structure to see each individual consideration, and with clash detection
capabilities that seamlessly integrate input from architectural drawings, MEPS
designs, constructability and interior designs into a holistic building
approach. By seeing a project from a
whole building vantage point rather than viewing a building plan as a series of
silos, developers are capable of producing efficiencies and a more streamlined
approach to the design and construction process.
Benefits associated with employing BIM software include
reduced errors and reworks and an overall maximized project outcome with
long-term savings.
3) Insulation Advancements
Insulation needs with regard to non-traditional building
methods, including solar and cargo containers among others, differ greatly from
customary approaches and solutions.
Insulation for emerging building methods must create an easy-to-manage
living environment from a thermal comfort perspective while minimizing the
space utilization requirement to create a desirable effect. Traditional insulation actually does not stop
the transfer of heat or cold between external environments and interior living
spaces, but rather it simply works to delay the transfer through multiple
inches of material designed to absorb hot and cold.
New insulation, like that being manufactured by Cargolinc,
actually repels external heat or cold without having to factor in the necessary
4-8 inches of insulation space that, in fact, would not mitigate the
condensation factor that metal runs against when facing a temperature
difference between outside and inside spaces.
Thus, traditional insulation would only create moisture in hard to reach
spaces that would promote mold and rot, rather than a comfortable, appealing
living environment in all climates.
Emerging insulation technologies maximize space while
providing the highest form of a thermal barrier that utilizes the Bernoulli
Effect—the effect that gives wings lift and creates eddies in rivers (and in
the case of insulation diverts heat and cold from the surface to block transfer
versus attempting to just slow it down as with common insulation). By spraying the inside and outside of a
structure with this sort of product that only requires 20mm of thickness
equating to the depth of two stacked business cards, usable living space is
greatly maximized. In addition, this
process also eliminates the condensation effect on metal and produces a
comfortable environment even in such remote locations as the desert and above
the Arctic Circle. This allows scaling
down HVAC systems to meet the reduced demand, which with this method is not
competing with the transfer/loss of heat and cold to the exterior environment.
All combined this lowers operating costs for building facility managers and
homeowners.
