Summer Conditions: A Precursor to Winter Woes?

Indications of potential thermal performance problems with exterior wall components are typically expected during the winter, but they can appear any time of year. In the example illustrated here, isolated areas of significant condensation on a curtain wall’s exterior surface occurred in mid-summer, raising the question of what factors led to this condition.

The design/construction industry is in the early stages of a revolution centered around a concept known as building information modeling (BIM). From early concept, programming, and document production to construction management and facility operation, BIM is a steadily growing delivery tool. Continue reading

Expectations, Realities, and Remedies

In spite of our best efforts, we occasionally commit errors testing our professional skills and demeanor. The daily demands on design professionals, especially specifiers, just about guarantee this. Research, documentation, correspondence, coordination, time entry, billing, time with reps, project meetings, all the way down to taking out the trash—the accumulation of all these tasks place trouble-free work more in the realm of ‘possibility’ than ‘certainty.’

However, the real spice in this mix is how desire to meet others’ expectations challenges our basic principles. Continue reading

Joinder and Consolidation in Arbitration

LAW
Werner Sabo, FAIA, CSI, and James K. Zahn, FAIA, CSI

It is a fairly common tale: the roof leaks in a newly constructed building, but the owner does not know whether it is a design or construction issue. The contracts with both the builder and the architect contain provisions requiring all disputes be arbitrated. The owner would like to have a single arbitration with both parties. Continue reading

A deeper look at ‘breathable’ curtain walls

In the August 2013 issue of The Construction Specifier, we included a Horizons column—“Introducing ‘Breathability’ to Curtain Walls—by Raymond Ting, PhD, PE.

As a complement to our more straight-ahead technical features, Horizons examines still-emerging technologies and new ways of assembling buildings. In this particular case, Ting dealt with the issue of glazed assemblies and their impact on both energy efficiency and indoor air quality (IAQ). He acknowledged building codes advocated for airtightness and air barriers, but called for new thinking about how ventilation—a good dose of fresh air, in other words—might be more critical for the occupants living or working inside.

Due to space constraints, a short sidebar article was kept out of the magazine. For a further look into the rationale behind Ting’s call for breathable curtain walls, it is included here. Continue reading
