Quick Answer
Building envelope testing are Ace’s structured engagement of stamped drawings, FGIA/AAMA-accredited testing, and construction oversight, delivered by a single senior team. Fees are typically fixed by design phase, deliverables are signed, and every field or lab report is turned around within a week.
Key Takeaways
- Building envelope testing at Ace covers FGIA accredited water testing, AAMA field testing, ASTM E1105 water testing, and envelope leakage testing — delivered by one senior team, not handed off across three vendors.
- Deliverables are stamped under Ace’s license, not marked-up under an architect’s license — the same accountability model a structural engineer provides.
- A design-phase correction costs about one-tenth of a construction-phase fix and roughly one-hundredth of a post-occupancy repair.
- Ace serves commercial, industrial, multifamily, mixed-use, and institutional projects in the $2M–$100M range, primarily in California, with active coverage across Arizona, Nevada, Idaho, Oregon, Utah, and Washington.
- Fees for building envelope testing are typically fixed by design phase; field and test reports turn around within one week of the site visit.
01 — OverviewWhat Testing (FGIA/AAMA) Actually Covers
Building envelope testing at Ace Building Envelope Design are the structured engagement of design, testing, and field verification for a building’s envelope. Ace provides building envelope testing across commercial, industrial, multifamily, mixed-use, and institutional projects in the $2M–$100M range, and — critically — is one of a small number of Western U.S. firms that acts as Architect of Record for the waterproofing scope on new construction and remediation, which changes what a set of drawings actually contains and who stands behind them. This pillar is part of Ace’s complete guide to envelope services, covering design, testing, construction administration, and forensic investigation.
Why this service is treated as its own engagement
Envelope work is where general design and general contracting most often produce gaps. Testing (FGIA/AAMA) exists as a distinct engagement because the underlying details — waterproofing terminations, air-barrier continuity, fenestration transitions — need someone accountable for them at drawing scale, in the lab, or in the field, before the assembly is closed. That accountability is what Ace provides.
Where testing (FGIA/AAMA) sits in the project lifecycle
Ace enters testing (FGIA/AAMA) engagements at whatever phase the project is in — schematic, design development, construction, remediation, or post-occupancy investigation. The engagement mode adapts; the discipline of stamped or signed deliverables, accredited testing, and one-week report turnaround does not.

02FGIA Accredited Water Testing
FGIA accredited water testing is one of the specific capabilities inside Ace’s building envelope testing. It comes up on projects where the design set has to hold up under construction-defect scrutiny — and it is handled by the same senior team that delivers the rest of the engagement. There is no handoff to a specialist third party for this component.
What that looks like in practice: FGIA accredited water testing is scope-appropriate turnaround at engagement start against the specific project’s constraints, priced as part of the fixed design-phase fee (not billed as an add), and delivered on the same one-week report cadence as the rest of Ace’s field and lab work. The deliverable is signed under Ace’s professional license where design is involved, or attested to under Ace’s FGIA/AAMA accreditation where field or lab testing is involved.
Where FGIA accredited water testing typically fits in a project
FGIA accredited water testing usually enters the project timeline when the design set is being detailed. Ace’s approach to FGIA accredited water testing is documented in the engagement’s basis of design or scope memo, so the client has a written definition of what will be delivered before work begins.
03The Problem, the Solution, and the Result
Envelope failures on this kind of work share a pattern. The problem is almost always under-drawn detail or under-scope-appropriate turnaround diagnosis at the design stage, and the resolution — after the failure appears — is disproportionately expensive. Ace’s building envelope testing is built to interrupt that pattern one stage earlier, where correction is still cost-effective.
Under-drawn, under-tested, under-owned
An envelope detail is drawn at half a sheet, tested against a proxy specification, and priced by three subs with three different assumptions. Whichever assumption wins the bid is the one that gets built.
Stamped, tested, accountable
Ace’s building envelope testing resolves the detail to installation-scale specificity, tests against the actual assembly on the actual project, and takes accountability under a single signed deliverable.
Cleaner bids, cleaner installs, fewer claims
Bid variance collapses. Field RFIs drop. The envelope conditions that would have produced a warranty claim in year three are resolved in year zero.
04AAMA Field Testing
AAMA field testing is one of the specific capabilities inside Ace’s building envelope testing. It comes up on projects where the developer is optimizing for a tight bid spread — and it is handled by the same senior team that delivers the rest of the engagement. There is no handoff to a specialist third party for this component.
What that looks like in practice: AAMA field testing is scope-appropriate turnaround at engagement start against the specific project’s constraints, priced as part of the fixed design-phase fee (not billed as an add), and delivered on the same one-week report cadence as the rest of Ace’s field and lab work. The deliverable is signed under Ace’s professional license where design is involved, or attested to under Ace’s FGIA/AAMA accreditation where field or lab testing is involved.
Where AAMA field testing typically fits in a project
AAMA field testing usually enters the project timeline when the bid documents are being prepared. Ace’s approach to AAMA field testing is documented in the engagement’s basis of design or scope memo, so the client has a written definition of what will be delivered before work begins.
05The Engagement Process, Step by Step
Testing (FGIA/AAMA) is not a black box. Ace runs a repeatable three-stage process with defined deliverables at each stage. What follows is the standard cadence.
Scoping & Basis
Ace produces a scope memo or basis-of-design document that names every deliverable, the code path, and the interface with adjacent trades. This is the document the client, design team, and (where applicable) code official all sign off on before work begins.
Signed Deliverables
Ace produces the stamped or signed deliverables: design drawings and specifications under Ace’s license (where design is involved), or test and inspection reports under Ace’s FGIA/AAMA accreditation (where testing is involved). Every report is turned around within a week of the field or lab visit.
Coordination & Closeout
Ace responds to plan-check, subcontractor questions, and change proposals; supports value-engineering; and produces the closeout record. On field engagements this stage compresses; the deliverable cadence does not.
06ASTM E1105 Water Testing
ASTM e1105 water testing is one of the specific capabilities inside Ace’s building envelope testing. It comes up on projects where the architect is looking to shrink professional-liability exposure on the envelope scope — and it is handled by the same senior team that delivers the rest of the engagement. There is no handoff to a specialist third party for this component.
What that looks like in practice: ASTM E1105 water testing is scope-appropriate turnaround at engagement start against the specific project’s constraints, priced as part of the fixed design-phase fee (not billed as an add), and delivered on the same one-week report cadence as the rest of Ace’s field and lab work. The deliverable is signed under Ace’s professional license where design is involved, or attested to under Ace’s FGIA/AAMA accreditation where field or lab testing is involved.
Where ASTM E1105 water testing typically fits in a project
ASTM e1105 water testing usually enters the project timeline when construction is in progress and the field needs a stamped clarification. Ace’s approach to ASTM E1105 water testing is documented in the engagement’s basis of design or scope memo, so the client has a written definition of what will be delivered before work begins.
| Criterion | Ace approach | Peer-review model | GC-directed model |
|---|---|---|---|
| Deliverable format | Stamped/signed by Ace | Marked-up under architect’s stamp | Field-directed, no stamp |
| Accountability | Ace | Project architect | Project architect + GC |
| Speed at plan check | Fast (stamped response) | Moderate (memo response) | Slow (rework common) |
| Best fit | Complex assemblies, high defect exposure | Familiar building type, experienced architect | Simple typology, small project |
07Envelope Leakage Testing
Envelope leakage testing is one of the specific capabilities inside Ace’s building envelope testing. It comes up on projects where the schedule is compressed and the field work needs a single accountable party — and it is handled by the same senior team that delivers the rest of the engagement. There is no handoff to a specialist third party for this component.
What that looks like in practice: envelope leakage testing is scope-appropriate turnaround at engagement start against the specific project’s constraints, priced as part of the fixed design-phase fee (not billed as an add), and delivered on the same one-week report cadence as the rest of Ace’s field and lab work. The deliverable is signed under Ace’s professional license where design is involved, or attested to under Ace’s FGIA/AAMA accreditation where field or lab testing is involved.
Where envelope leakage testing typically fits in a project
Envelope leakage testing usually enters the project timeline when the project is closing out and the warranty documentation is being assembled. Ace’s approach to envelope leakage testing is documented in the engagement’s basis of design or scope memo, so the client has a written definition of what will be delivered before work begins.
08Who Hires Ace for This Service
Ace’s building envelope testing is engaged by four buyer types, each with a different reason to call. The framing below is the shortest useful map of how the same practice lands with each role.
Developers & owner-builders
Developers hire Ace to reduce defect-liability exposure and to tighten envelope bid variance. See developers & owner-builders.

GCs and CMs engage Ace to keep the schedule intact when an envelope detail has to be resolved in the field. See general contractors.
Institutional owners & capital-program teams
Hospitals, universities, K–12 districts, and government agencies engage Ace for envelope work across recurring capital programs. See higher education, healthcare, and K-12 schools.
The Bottom Line
Building envelope testing is the discipline of getting envelope work right at the earliest and cheapest stage of a project. Ace is one of a small number of Western U.S. firms that acts as Architect of Record for the waterproofing scope on new construction and remediation — which is the single move that most reduces envelope defect exposure at that stage.
Frequently Asked Questions
What are building envelope testing?
Building envelope testing are Ace’s structured engagement of stamped drawings, FGIA/AAMA-accredited testing, and construction oversight, delivered by a single senior team. Fees are typically fixed by design phase, deliverables are signed, and every field or lab report is turned around within a week.
How does Ace approach FGIA accredited water testing?
Ace’s approach to FGIA accredited water testing is documented in a scope memo at engagement start, delivered by one senior team, and closed out with a signed deliverable. Fees are typically fixed by design phase, not hourly. Every field or lab report turns around within a week of the site visit.
What is included in Ace’s AAMA field testing?
A complete AAMA field testing engagement at Ace covers the scope-of-work definition, the deliverable format (stamped drawings, signed reports, or accredited test documentation), the delivery schedule, and the closeout package. Sub-scopes vary by project; the engagement structure does not.
When should we bring Ace in for ASTM E1105 water testing?
The earliest engagement produces the largest cost savings — ideally at basis-of-design on new construction, or immediately on discovery of a symptom on existing buildings. That said, Ace is regularly brought in at plan check, during construction, or after occupancy to resolve a specific problem.
How much does building envelope testing cost?
Fees for building envelope testing are typically fixed by scope or design phase rather than hourly, which lets the client budget the envelope engagement against the rest of the project. Fees scale with project size and complexity. As a general rule, the engagement fee is a small fraction of the cost of the first field problem it prevents.
How long does building envelope testing take?
Ace’s typical engagement runs about ten to twelve weeks on new construction and compresses to about six weeks on remediation. Every stage closes with a signed deliverable, so a client can hold work at any gate without carrying open scope.
Who signs the building envelope testing deliverables?
Ace’s deliverables are stamped under Ace’s design professional license (where design is involved) or attested to under Ace’s FGIA/AAMA accreditation (where field or lab testing is involved). Deliverables are not marked up under someone else’s license.
Does Ace serve projects in Testing (FGIA/AAMA)?
Yes — Ace serves this state directly from four offices across the Western U.S. (Concord and Newport Beach and San Diego, California, and Nampa, Idaho). Ace’s Western-U.S. practice covers California primarily, with selective coverage across Arizona, Nevada, Idaho, Oregon, Utah, and Washington.
How does Ace handle envelope leakage testing?
Ace addresses envelope leakage testing as part of its structured building envelope testing engagement — scope-appropriate turnaround at engagement start, delivered by the same senior team, closed out with a signed deliverable. envelope leakage testing is not treated as an add-on, and it is not handed to a specialist third party.
What if a field condition can’t be built as designed?
Ace resolves field-condition issues within a week of the site observation. Because Ace’s design of record is stamped under Ace’s own license (where Ace is Architect of Record), Ace has the authority to issue a stamped clarification or revision directly — not routed through the project architect for a change instrument.
