01 / EXPERTISE

Advisory and support,
on your terms.

Deliverables are advisory and support-focused, prepared in collaboration with the architects and engineers of record. I work as an extension of your team—on a single submittal package, or through an entire construction phase.

01

NEW CONSTRUCTION

Specifications & details

Architectural specifications, drawings and details for curtain wall, window wall, skylights, cladding, roofing and waterproofing, developed with your design team. Careful attention to transitions, drainage and continuity of air, water and thermal barriers helps turn design intent into buildable assemblies.

02

DURING CONSTRUCTION

Shop drawing & submittal review

Review of shop drawings and material submittals for curtain wall, glazing, cladding, waterproofing and firestopping against the contract documents. Reviews address interface details, material compatibility and sequencing between trades to resolve gaps before installation, with comments tracked through to closure on resubmittal.

03

EXISTING BUILDINGS

Condition assessment

Site observation and close-up investigation of facades, roofs, and glazing, with prioritised findings and order-of-magnitude costs for capital planning.

04

VERIFICATION

Lab testing & field review

Testing scope, witnessing and interpretation for custom building envelope systems in the laboratory, including AAMA 501 mock-up testing. On-site spray-rack testing and field reviews assess performance and installation against the reviewed submittals and applicable standards below. Advisory support also addresses Tarion Bulletin 19 (B19) design and field review requirements and Pro-Demnity window-wall considerations, in collaboration with the project’s architects, engineers and field review consultants.

Principal Consultant

I bring more than 15 years of experience across consulting engineering, architectural practice and owner’s representation. My work connects the technical demands of building envelopes with the practical realities of design, construction and long-term operation. From glazing and facade rehabilitation to major transit infrastructure, I help project teams understand existing conditions, resolve complex interfaces and turn design intent into clear, buildable details.

Since establishing Jimmy Tang Consulting in 2023, I’ve provided independent building envelope and architectural advisory services, working closely with architects and engineers of record.
