PART 1 - CLARIFICATIONS

1.1 GEOTHERMAL HVAC ALTERNATE – The geothermal alternate includes a revised specificationfor the ground-mounted RTU; deleting furnace and condensing units and replacing withground source heat pumps; adding primary loop pumps; adding an interior buildinggeoloop, and designing an 85 ton geo-exchanger with 7-8 zone loop pumps and an interiorpiping loop to all units. Schedules are included in this addendum for revised HVACequipment. All units shall have source-water two-position two-way valves and primary looppumps shall be pressure-controlled variable speed driven. Zone loop pumps shall bevertical inline, constant speed. Mechanical/Controls contractor shall provide VFD’s and unitcontrol valves. EC shall include in their proposal the revised power connections and the newequipment connections (pumps, GSHP, and RTU) per the new schedules. Geo-exchangerconfiguration could be vertical or horizontal wells or horizontal loops.

PART 3 EXECUTION3.01 EXAMINATION AND PREPARATION

A. Verify location of existing structures and utilities prior to excavation.B. Verify soil composition and rock depth, if any, before beginning excavation.C. Protect adjacent structures from the effects of excavation.D. Verify that layout dimensions are correct and that available land is sufficient for design.E. Notify Architect/Engineer of unsatisfactory conditions.F. Do not proceed with installation until unsatisfactory conditions have been corrected.G. Coordinate work with site grading, site backfilling, and foundation construction.

3.02 EXCAVATIONA. Excavate in accordance with requirements of authorities having jurisdiction.B. Remove rock as specified in Section 31 2316.26.C. Vertical Boreholes: Drill to depths required.

1. Minimize over-drilling; fill over-drilled areas with backfill or excavated materials.2. Piping: Assemble heat exchanger piping and test before installation.

D. Trenches: Excavate trenches for piping to lines and grades shown on drawings.1. Minimize over-excavation; fill over-excavated areas with backfill or excavated

materials.2. Excavate to accommodate grade changes.3. Maintain trenches free of debris, material, and obstructions that may damage

pipe.4. Piping: Assemble heat exchanger piping and test before backfilling.

3.03 POLYETHYLENE PIPINGA. Join piping and fittings using heat fusion or electrofusion; do not use solvents, adhesives,

or mechanical fittings.B. Provide flanges or unions to connect heat exchanger piping to equipment or piping of

different type; locate all transitions between piping of different types inside the buildingor otherwise accessible (i.e. above grade).

C. Keep dirt, water, and debris out of pipe assemblies; cap or plug open ends untilconnected to adjacent piping.

D. Do not bend piping to shorter radius than recommended by pipe manufacturer; donot kink piping; use elbow or other fittings for sharp bends.

E. Partially backfill radius bends in narrow trenches by hand to ensure that piping isproperly supported and to prevent kinking.

F. Test piping to be installed in boreholes after assembly but before installation inboreholes; re-cap tested assemblies before installation.

G. Test piping to be installed in trenches after installation but before backfilling.H. Testing: Perform hydrostatic test on all piping; portions of assembled piping may be

tested separately.1. Prior to testing, isolate piping from all connections to building systems.2. Flush all dirt and debris using potable water flowing at twice the normal operating

flow rate for a minimum of four hours or until no dirt or debris is visible, whichever islonger.

3. Plug or cap piping.


4. Pressurize piping to 150 psi for 30 minutes and monitor.5. If there is any pressure loss or visible leakage, identify leak and repair in

accordance with manufacturer's recommendations.6. Repeat test until there is no loss of pressure for the duration of the test.

I. Where piping passes through foundation walls, provide sleeves sealed withnon-hardening, waterproof material.

J. After connection of piping to building systems and installation of equipment served byheat exchanger, fill piping with heat exchange fluid and pressurize.1. Water Temperature of 70 to 90 degrees F: Pressurize to 20 to 30 psi, minimum.2. Water Temperature of 40 to 50 degrees F: Pressurize to 40 to 50 psi, minimum.3. If adequate flooding of circulating pump can be accomplished without

pressurization and pump manufacturer approves, pressurization is not required.4. After pressurization, remove charging valve handles, or plug ports, whichever is

applicable, and deliver handles to Owner.5. Install system label at charging valves, indicating:

a. Heat exchange fluid, including antifreeze type and concentration.b. Service date.c. Company name.d. Company phone number and responsible person.

3.04 BACKFILLINGA. Install in compliance with local authorities having jurisdiction.B. Vertical Boreholes: Backfill after pipe installation in accordance with IGSHPA Grouting

Procedures for GHP Systems.C. Trenches:

1. Provide minimum 60 inch cover over piping.2. Backfill trenches after pipe has been installed and tested, using fill free of rocks

and other debris.3. Install detectable tape continuously 6 inches above top of all buried pipe.4. Backfill and compact using the procedures specified in Section 31 2316.13.5. Backfill to original grades with sufficient overfill to allow for settlement.

D. Protect piping from displacement.3.05 PROTECTION
