c. Tricon Piping Systems, Inc., Steel-Con Plus System
d. Thermacor Process, L.P., Duotherm 505 (HDPE) System
2. Service pipe and outer conduit miters may be implemented by the contractor in accordance with
the manufacturer’s recommendations but under no circumstances may the miter exceed 10
degrees.
3. The service pipe insulation for the pre-insulated direct-buried piping shall incorporate an additive
which makes it water repellent and water wicking resistant. Insulation product shall be tested in
affirmative compliance with the U.S. Navy’s “96 Hour Conduit Boiling Test” requirements. Each
service pipe shall be in a separate steel outer conduit. The conduit shall be ASTM A — 139
smooth wall, spiral or ERW welded steel, of sizes 10 gauge for up to 26” diameter, 6 gauge for
28-36” diameter, and 4 gauge for 38-42” diameter.
4. The steel outer conduit shall be insulated with spray applied polyurethane foam on all straight
lengths and fittings. The urethane foam shall meet ASTM C591 and have the minimum
characteristics of .18 K-factor, density of 2 pcf and a closed cell content of 90 to 95% with a
compressive strength of 40 psi. Quality assurance procedures for the foam insulation shall include
either a visual check prior to jacketing, infrared, or radiographic (x-ray) testing to insure there are
no insulation voids. Manufacturer shall provide documented test results, to include interpretation,
for infrared or radiographic testing for a minimum of all the piping on the first truckload
delivered to the project site. Testing shall be provided on at least one length of each size pipe as
well as at least one of each size pipe elbow and anchor. Additional truckloads shall not be
shipped until the University has accepted the test results. If the test results are rejected, insulation
must be corrected and new test results submitted. If any test is rejected, all product associated
with this project must be tested accordingly.
5. High density polyethylene (HDPE) factory installed jackets are required for all preinsulated
piping systems. HDPE jacket shall be a minimum of 150 mils thick for all pipe sizes.
6. Joint sealing system shall be CANUSA SuperCase CSC — X joint sealing system. Where service
pipe and outer conduit field miters between 3 and 10 degrees are necessary and are permitted by
the manufacturer, instead apply the CANUSA CSC—X WA wrap around joint sealing system
over the foam. The joint sealing system shall be fully certified to EN 489 requirements.
7. Keep the pipe system interior clean and dry at all times during installation. Grade top perimeter of
excavations to prevent surface water run-off into excavation. Maintain bottom of all excavations
stable, dry and free of water on a continual basis. Pipe shall be laid in the dry trench conditions.
At no time shall water in the trench be permitted to flow into the pipe system interior. Contractor

106. BIDDER QUESTION 106: Addendum 1 deleted glass type GL-6, fire rated glazing. The door
schedule on page A00-50 of the drawings show many type G doors having a 45 minute rating.
Please advise as to what type of glass is to be used in the doors with a fire rating considering the
fire rated product listed in the specifications was deleted?
Fire Rated glass is not required for Lites in Door Type G (lites shall be 4” x 24” which is
under 100 square inches)
107. BIDDER QUESTION 107: None of the doors, hollow metal frames or storefront specify a glass
type to be used. Please provide information regarding what glass type is used in each door,
frame and storefront?
Door Type A: GL-2
Door Type B: GL-2
Door Type E: GL-2
Door Type G: GL-2
Sidelites in Frame Type 2 and 3: GL-2
Window Type N, M, P: GL-1
Glazing in Storefront shown on A11-30 (Vestibule 299H): GL-2
108. BIDDER QUESTION 108: Please clarify the flexible membrane strips at masonry openings in
spec. section 072100 Thermal Insulation vs. the modified bituminous strip air barriers in spec.
section 072713. For example, we are looking at details 5 and 6/ A11-24: is it your intent to have
the membrane strip shown here installed by the insulation contractor or by the filed sub-bid
waterproofer. Also referring to details 1 and 2/A11-24 is it your intent to have the peel and stick
new AV barrier installed by the filed sub-bid waterproofer?
Membrane strip shown in details 5 and 6 on A11-24 shall be installed by the filed sub-bid
waterproofer. Peel and Stick AV barrier shown in details 1 and 2 on A11-24 shall be
installed by the filed sub-bid waterproofer.
