From Testing and Legal Contracts to Components, BEC Sessions Cover Range of Topics

“You want to know the barriers to getting paid … what do you have to fight?” she questioned.

She then looked at a number of payment provisions. Pay-if-paid clauses, for example, shift the risk of the owner’s non-payment to the subcontractor.

“There are a lot of places/states where these not enforceable,” she said, but added, “but are enforceable in the bulk of jurisdictions across country.”

So, what should a subcontractor do if there is a pay-if-paid clause? Briglia said to ensure the subcontract terms are incorporated downstream.

“Perfect your condensations lien and bond rights; look to prime contract clause for ambiguities,” she said.

She added there are other key contract provisions every project manager should know at project commencement such as disputes provisions; time limits; interest and attorney’s fees; notice requirements; and waivers and exculpatory provisions.

Speaking of waivers, she added that in order to get a progress payment you have to sign a lien.

“Be careful when you sign waivers because you could be giving up your rights,” she advised.

The BEC Conference also included a panel discussion that looked at the “connections between the components.”

Lam from WJE talked some about the inner-connectivity between components, as well as some potential concerns and challenges. Continuity issues to consider include the primary Seal Connection (i.e., air and water), thermal enclosures/boundaries, as well as existing building construction. Challenges can fall within areas such as design complexity and material compatibility.

There can be a number of consequences due to component discontinuity, he explained. These can include high energy costs, poor thermal comfort, uncontrolled indoor environment, such as humidity and outdoor contaminants, large forces for rain penetration and increased sound transmission.

He was followed by Patrick Schmidt of Halfen who reviewed curtainwall anchoring. Schmidt talked about different connection types and said the most common are welded, drill-in and adjustable bolted.

With welded connections, that is embedded weld plates, he explained, some considerations include there can be safety hazards from sparks and fume, as well as potential damage to installed aluminum and glass. He said this type can also be time-consuming to install and require up to four people for welding. There is also limited adjustability. Drilled in connections, post-installed anchors, he continued, typically require some coordination with general contractor. Other considerations he mentioned include potential damage to post-tensioned slabs; the necessity for power tools; and they, too, can be time-consuming.

Speaking of adjusted bolt connections, Schmidt said these are cast-in channel applications and require coordination between the glazing contractor and general contractor. He said many sizes and capacities are available for different applications, and the anchors are adjustable to accommodate construction tolerances and reduced field labor. They also do not require onsite welding or drilling.

Peter Poirier of Tremco discussed sealants as well components as well as water-barrier materials. He noted the importance of compatibility among materials such as the sealants and other water performance materials to ensure a tight application. His presentation included numerous slides, drawings and videos to illustrate how the materials best work together.
