BE and the High C’s: Specification Writing with Enclosure Consultants in Perfect Pitch 1.0 CEU/HSW
2026-09-17 13:00 - 14:00
The 4 C’s—Clear, Correct, Concise, and Complete—form the foundation of effective technical and specification writing. Building Enclosure Consultants (BECs), however, may not be fluent in the language of specifications, often viewing it as a misunderstood second language. As a result, the work of specification writing becomes doubly challenging when collaborating with BECs.
This session explores the range of building enclosure consulting scopes and processes that directly influence building enclosure specifications, including Building Enclosure Commissioning (BECx), which is rapidly becoming both a high-performance building expectation and a code-driven requirement. To bring this sometimes-awkward working duet into perfect pitch, specification writers must learn to harmonize with BECs—using the 4 C’s as their common language—to clearly communicate enclosure intent, responsibilities, and performance requirements.
Learning Objectives:

Review the 4 C’s as presented by CSI. Consider additional C’s in the specification writing process. Present these concepts to Building Enclosure Consultants.
Analyze the Building Enclosure Commissioning (BECx) process from pre-design through the 10-month warranty walkover, and apply to the specification writing process.
Compare the range of BECx activities, tasks, and requirements from the governing standards and organizations of NIBS, ASTM E2813 and E2947, LEED v5, USACE, and ASHRAE 90.1, and 2021 IECC.
Interpret the variations of the typical building consultant’s scope and processes versus BECx, and the extent of building enclosure deliverables relative to the specification writing process.

Yet, the built environment remains fundamentally human—designed for people, shaped by context, and realized through collaboration. This presentation offers a multidisciplinary perspective, drawing from the experiences of architects, contractors, and owners to examine how real-world, cross-disciplinary coordination remains essential to delivering high-performance buildings, even as digital tools become more prevalent. It highlights lessons from projects where human communication—not automation—was the key to maintaining design intent, continuity, and constructability. The session explores how to achieve better buildings from start to finish—showing that beyond maintaining assembly and system continuity, true performance depends on project team continuity. From breaking ground to drying in, the presentation illustrates how proactive coordination, clear scope definition, and interface and goals alignment can prevent the missteps that lead to failure. Emphasis is placed on applying first principles and fundamentals to navigate complex conditions and develop simple, collaborative solutions.
Learning Objectives:

Identify critical coordination points that affect enclosure continuity and performance from design through construction.
Describe how early, discipline-wide collaboration mitigates scope gaps and interface failures in enclosure assemblies.
Discuss practical strategies for maintaining communication and alignment among project stakeholders.
Apply lessons from field and desk to improve constructability and performance of air, moisture, and thermal control layers.
