and Systems;
c.ASTM E2813, Standard Practice for Building Enclosure Commissioning;
d.ASTM E2947, Standard Guide for Building Enclosure Commissioning;

Fan Pressurization;
f.ASTM E1827, Standard Test Methods for Determining Airtightness of
Buildings Using an Orifice Blower Door;
Envelope Commissioning Scope of Work
We recommend also considering engaging additional 3rd party inspectors to address
specific quality control oversight that may overlap with or be tangential to this BECx
scope and delivery as described in this proposal. For example, it may be in the best
interest of the owner and contractor to employ a manufacturer-approved inspector for the
membrane roofing system who will focus on QC of the installation procedures and
warranty requirements, whereas the BECx scope and delivery will provide parallel
quality control oversight focused on compliance to the design intent. This concept may
apply also to QC of the installation of systems including the WRB/air barrier,
fenestration, and glazed façade assemblies, etc.
The following are descriptions of the construction phase BECx services we propose.
1.0) During Construction: Whole Building On-site Envelope Construction
Reviews
We will make periodic on-site reviews of the construction of the building envelope and at
appropriate intervals we will submit commissioning field reports specific to our BECx
reviews. Our focus will be on:
Issues or concerns related to overall envelope construction
including air, moisture/weather and thermal barriers.
Envelope primary air barrier, and compliance to IECC 2012
C402.4.1 Air Barriers.

ELKHORN COMMISSIONING GROUP • PO BOX 11826 • BOZEMAN, MT 59719
We are budgeting six (6) such on-site reviews. In some cases, a single field report may
encompass the findings of two or more on-site reviews, i.e. there will not necessarily be
BECx field reports submitted after each on-site review.
2.0) Early-Construction Water Intrusion, Air Infiltration, and Air Barrier
Adhesion Testing at In-Situ Mockup(s)
We propose to lead the testing as outlined in this proposal, as well as the BECx Plan. In
some cases, we are proposing different test methods than what is specifically identified in
the specifications because we believe the proposed approach meets design intent and
provides the best value.
This proposal is based upon completing air leakage, water leakage and air barrier
adhesion tests using in-situ mockups of window, wall, and fenestration assemblies as
appropriate to facilitate real-world conditions. Number of tests will be determined by
construction sequencing/scheduling, performing tests of similar assemblies early is
critical to prove effectiveness of design/installation of details.
Air Leakage Testing
Qualitative air leakage testing according to ASTM E1186
AND
Water Leakage Testing
Pass/Fail water leakage testing according to AAMA 501.2
3.0) Mid- to Late-Construction Water Infiltration Pass/Fail Testing at
Fenestrations, Storefronts and Curtain Walls to AAMA 501.2 with
Simultaneous Diagnostic Qualitative Assessment of Air Barrier Performance
according to ASTM E-779
Water Leakage Testing
We are proposing water leakage testing of storefronts and curtain walls according to
either or both ASTM E1105 and AAMA 501.2, depending on state of building at the time
of the test. ASMT E1105 includes application of water to the fenestrations while there is
a differential pressure induced between the interior and exterior sides of the wall. The
ability to develop and maintain the differential pressure depends on construction of
temporary enclosures, and the construction of such enclosures is impacted by or may
impact the overall construction schedule. AAMA 501.2 is similar but does not require a
pressure differential across the envelope. Water is applied to the exterior in a controlled
fashion but without the pressure differential between inside and outside. The rate of
water application and pass/fail criteria are different.
We are proposing the option to conduct testing of storefronts and curtain walls according
to AAMA 501.2 as a lower cost (per unit area), lower-impact testing method that is less
dependent on coordination with the overall construction schedule. If the schedule allows,
we may perform the 1105 test in place of the 501.2 test.

ELKHORN COMMISSIONING GROUP • PO BOX 11826 • BOZEMAN, MT 59719
We will test representative sections of the storefront and window assemblies for
deficiencies or concerns regarding water barrier performance. Water leakage testing will
be conducted according to AAMA 501.2. Air barrier performance will not be assessed
specifically under the AAMA 501.2 method since there is no pressure differential.
Air Leakage Testing
Once the primary air barrier is installed and continuous, including enough windows,
doors, etc to allow for test, we will perform an ASTM E-779 full building Blower Door
Test. Pass/fail will be determined relative to the maximum allowable leakage per IECC
2018 of 0.4 CFM/ft2 of envelope area.
4.0) Final Report
We will provide a concise final report that will compile the field reports and test results
from the on-site reviews and tests.
Contractors (and sub-contractors) Responsibilities:
Provide access to the project site to the Commissioning Authority
(CA)
Attend coordination meetings
Provide a lift and a lift operator for accessing any above-grade
portions of the envelope that will be tested
Review Cx Issues Logs and field reports provided by the CA, take
appropriate actions to resolve issues that have been identified, and
provide regular updates regarding issues statuses to the CA
Commissioning Authority Responsibilities, Activities and Deliverables:
Direct and perform envelope testing with participation of and
assistance by the GC or installing subcontractors
