PART 3 EXECUTION

3.1 PREPARATION

A. Operate, fill, start and vent systems prior to cleaning. Use water meter or trace chemical calculation method to record capacity in each system. Place terminal control valves in open position during cleaning.

B. Provide a permanent tag with “updated total” system capacity information and attach it to the air eliminator.

3.2 TEMPORARY CIRCULATING PUMP FOR SYSTEM CLEANING

A. The scope of this project includes adding a new hydronic piping loop connected to the existing larger building hydronic loop. The mechanical contractor shall temporarily isolate the new piping loop as required so that it may be cleaned independent of the larger building loop. A temporary pump shall be connected to the loop and utilized to meet the cleaning requirements of this section. The pump shall be removed after the cleaning

process is complete. The new loop will then be connected to the existing larger building loop. 3.3 INITIAL TESTING

A. The water source for filling and flushing must be tested and approved by contracted chemical treatment company to verify compatibility with cleaners, glycols and inhibitor packages. B. If new piping is tying into an existing system, the existing system must be tested to verify the system “starting point”. It will be the mechanical contractor’s responsibility to coordinate with the Owner’s Representative all adjustments and improvements needed with the existing piping system to bring it to a good, clean and chemically balanced condition. Costs for these adjustments shall be the Owner’s responsibility. When the existing system’s quality is established to the Owner and Engineers satisfaction the Mechanical Contractor shall ensure that the final system is of the same or better quality than the existing system “starting point”.

3.4 INITIAL SYSTEM FLUSH

A. The addition to the system will initially be filled with approved water and thoroughly flushed to remove any dirt and debris from the materials of construction. The system must be filled and drained from points which maximize flow throughout the entire loop. A system pressure of at least 10 psig must be maintained during the flush. B. All valves in the loop must be in the open position during the flushing process.

C. The initial flush must last for at least four continuous hours. The flush will be considered a success when the water exiting the loop contains less than 80 ppb of total suspended solids.

3.5 SYSTEM CLEANING

A. The system will be filled to 5% of total volume with Jaytech’s JT3450 or JT3415 (or equal) all in one multi-metal cleaning solution. B. The system must be circulated with the cleaner continuously for at least 48 hours and no more than 10 days. Old or fouled piping may require additional cleaner or circulation time. Raise loop temp to 180°F in boiler systems to improve cleaning. C. The addition to the system must be filled and drained with approved water from points which maximize flow throughout the entire loop. A system pressure of at least 10 psig must be maintained during the flush. D. The addition to the system must then be flushed for a period lasting at least 48 hours but no more than 7 days. E. The flush will be considered a success when the water exiting the loop contains less than 80 ppb of total suspended solids and less than 300 RLUs of biological content using an ATP test meter. F. Sufficient flush water is imperative to the timeline of the flushing process. 15- 30 times the systems volume per day must be maintained.

3.6 CLOSED LOOP TESTING

A. Babcock/Wilcox Millepore testing and biological testing must be conducted on each loop that is cleaned and flushed at the cost of the mechanical contractor. Millepore results must yield less than 80 ppb of total suspended solids and ATP biological testing must yield less than 300 RLUs in order to consider the clean and flush a success. B. The water treatment company testing both the existing piping system and the additional piping loop must provide a written report documenting all testing conducted on the loop. Copies of the report must be provided to the mechanical contractor and the building owner.

3.7 CLOSED SYSTEM TREAMENT A. Provide one bypass pot feeder on each system. Install isolating and drain valves and

interconnecting piping. Install around pump differential to insure adequate flow.

mechanical clamps. 4. Make aluminum-to-galvanized steel connections with tin-plated copper jumpers

and mechanical clamps. 5. Coat and seal connections having dissimilar metals with inert material to prevent

future penetration of moisture to contact surfaces. B. Exothermic-Welded (CADWELD) Connections: Use for connections to structural steel and for underground connections, except those at test wells. Comply with manufacturers written instructions. Welds that are puffed up or that show convex surfaces indicating improper cleaning are not acceptable. C. Equipment Grounding-Wire Terminations: For No. 8 AWG and larger, use pressure-type grounding lugs, SLUH type, No. 10 AWG and smaller grounding conductors may be terminated with winged pressure-type connectors.

D. Non-contact Metal Raceway Terminations: Where metallic raceways terminate at metal

housings without mechanical and electrical connection to housing, terminate each conduit with a grounding bushing. Connect grounding bushings with a bare grounding conductor to grounding bus or terminal in housing. Connect grounding bushings with a bare grounding conductor to grounding bus or terminal in housing. Bon electrically non-continuous conduits at both entrances and exits with grounding bushings and bare grounding conductors, except as otherwise indicated.

• Zones with occupancy and/or photocell sensors turn lights off when vacancy or sufficient daylight is detected.

• Pressing a switch will turn lights off. The lights will remain off regardless of occupancy until switch is pressed again, restoring the sensor to Automatic On functionality.

2. Manual-On / Auto-Off (also called Semi-Automatic) • Pushing a switch will turn lights on. • Zones with occupancy and/or photocell sensors turn lights off when vacancy or

sufficient daylight is detected. 3. Manual-On to Auto-On/Auto-Off

• Pushing a switch will turn lights on. • After initial lights on, zones with occupancy and/or photocell sensors turn lights

on/off according to occupancy/vacancy and/or daylight conditions. • Sequence can be reset via scheduled (ex. daily each morning) events

4. Auto-to-Override On • Zones with occupancy sensors automatically turn lights on when occupant is

detected. • Zone lighting then goes into an override on state for a set amount of time or until

the next time event returns the lighting to an auto-off style of control. • Sequence can be reset via scheduled (ex. daily each morning) events

5. Manual-to-Override On • Pushing a switch will turn lights on. • Zone lighting then goes into an override on state for a set amount of time or until

the next time event returns the lighting to an auto-off style of control. • Sequence can be reset via scheduled (ex. daily each morning) events

6. Auto On / Predictive Off • Zones with occupancy sensors automatically turn lights on when occupant is

detected. • Zones with occupancy and/or photocell sensors turn lights off when vacancy or

sufficient daylight is detected. • If switch is pressed, lights turn off and a short “exit timer” begins. After timer

expires, sensor scans the room to detect whether occupant is still present. If no occupancy is detected, zone returns to auto-on. If occupancy is detected, lights must be turned on via the switch.

P. When noted as “networked” control, a taskbar style desktop application shall be available for personal lighting control.

Q. When noted as “networked” control, an application that runs on “smart” handheld devices (such as an Apple® IPhone®) shall be available for personal lighting control.

2.2 SYSTEM OPERATION AND STARTUP SEQUENCE

A. SiteSync IQ system receives atomic time information from Ethernet. The system controller is a powerful multi-tasking device that is capable of sending precise time information to synchronize all the system wireless clocks and accessories. The system can be monitored and programmed from the SiteSync IQ system controller keypad or via your PC web browser if you have the Remote Connect capability. It’s important to follow steps in this order: Install system controller, confirm signal reception and then install clocks.

2.3 WIRELESS SYSTEM CONTROLLER OPERATION A. When power is first applied to the SiteSync IQ system controller, the user shall complete

the Startup Wizard to initiate system operation and signal transmission. The Site Sync IQ system controller looks for the time signal every hour from the time source your system is designed to synchronize with. Once the system controller has received the time synchronization it sets its internal clock to that time. The system controller then starts to transmit the internal time. The system controller features an on-demand Ethernet sync capability which is initiated by the User/installer to sync the time.

Apply water in minimum quantity as necessary to prevent free water from appearing on

surface during or subsequent to compaction operations.

1. Remove and replace, or scarify and air dry, soil material that is too wet to permit

compaction to specified density.

2. Stockpile or spread soil material that has been removed because it is too wet to

permit compaction. Assist drying by discing, harrowing, or pulverizing until

moisture content is reduced to a satisfactory value.

3.11 ROUGH GRADING

A. Remove topsoil from areas to be excavated, re-landscaped, or re-graded, without mixing

with foreign materials. Stockpile on-site for re-use upon completion of grading operations.

B. Do not remove topsoil when wet.

C. Make soil corrections defined in the Geotechnical Report; follow procedures and use

materials defined in the Report. Generally:

1. For structures, including footings and isolated column footings, excavate full depth

to remove topsoil, organic and fill soils and and expose natural glacial soils. Exposed

subgrade soils should be evaluated by the project geotechnical engineer to

determine their suitability for support of foundation and slab loads.

a. If excavation extends below required footing bearing elevation, oversize

laterally beyond the outside edges of the foundations at a ratio of 1:1

lateral oversize.

b. Where excavations are adjacent to existing foundations, excavations should

not extend within a zone extending outward a distance of 5 feet from the

existing slab or footing and then down and outward at a slope of 1:1. The

geotechnical consultant should evaluate the suitability of the remaining

soils for foundation and slab support. If excavations are required within

these limits, ground improvement, retention or underpinning may be

required, as directed by the geotechnical consultant.

c. Obtain approval of on-site geotechnical consultant before proceeding with

compaction and fill work.

d. Surface compact exposed natural soil surface.

e. Place and compact backfill soils; see Geotechnical evaluation report, along

with structural plan notes and Section 32 05 00 for additional requirements.

2. For pavement surfaces, subcut the existing soil to allow the new pavement section.

Obtain approval of on-site Geotechnical consultant before proceeding with surface

compaction of the exposed, existing soil surface.

D. Remove subsoil from areas to be further excavated, re-landscaped, or re-graded.

E. Do not remove wet subsoil, unless it is subsequently processed to obtain optimum moisture

content.

F. When excavations extend below footing and slab bearing elevations, oversize the

excavation horizontally 1 foot for every foot of excavation depth below the indicated

bearing elevation.

G. When excavating through roots, perform work by hand and cut roots with sharp axe.

H. Benching Slopes: Horizontally bench existing slopes greater than 1:4 to key fill material to

slope for firm bearing.

I. Stability: Replace damaged or displaced subsoil to same requirements as for specified fill.

3.12 FINISH GRADING

A. Before Finish Grading:

1. Verify building and trench backfilling have been inspected and tested.

2. Verify subgrade has been contoured and compacted.

B. Remove debris, roots, branches, stones, in excess of 1/2 inch in size. Remove soil

contaminated with petroleum products.

C. Where topsoil is to be placed, scarify surface to depth of 3 inches.

D. In areas where vehicles or equipment have compacted soil, scarify surface to depth of 6

inches.

deleterious matter and rocks over 1” in diameter. Place the bedding material

uniformly over the trench bottom to a minimum depth of 3”. Shape the material to

give uniform support to the lower fourth of the pipe for its entire length. Make

depressions in the bedding to accommodate the joints. Carry bedding material to

6” above the top of the pipe.

C. Pipe Laying

1. Do not lay the pipe in water or when the trench or weather conditions are not

suitable for the work except by permission of the Engineer. When the work is not in

progress, securely close open ends of the pipe and fittings so that no water or other

foreign matter enters the pipe or fittings.

2. Unless shown otherwise on the plans, the pipe shall have a minimum of 7.5’ of

cover below all finished elevations and shall not be laid closer horizontally than 10’

to a sanitary sewer line. Deflections from a straight line or grade as required by

horizontal or vertical curves shall not exceed 5 degrees (a 5-degree deflection is

equivalent to an offset of approximately 1” per lineal foot of pipe). If the alignment

required deflects in excess of this limit, provide bends and fittings or shorter lengths

of pipe until these conditions are met. Brace bends and fittings in the pipe with

concrete thrust blocks poured in place against undisturbed earth.

D. Gate Valves and Valve Boxes

1. Install where shown on the plans or as directed by the Engineer.

2. Set the gate valves and valve boxes plumb and center the valve boxes on the valves.

Carefully place and compact fill materials around the valve box for a distance of 4’

on all sides of the box, or to the undisturbed trench face, whichever is less. Set the

top of the valve box at the elevation of the existing ground or as shown on the

plans.

3. Post indicator valves shall be maintained in a plumb position with 36” between the

finish ground elevation and the top of the valve.

3.02 SANITARY SEWER, STORM SEWER, AND WATER CROSSINGS

A. Water pipe crossing sewers shall be laid to provide a separation of at least 12” between the

bottom of the water pipe and the top of the sewer. When local conditions prevent a vertical

separation as described, the following construction shall be used.

1. Construct the sewers of materials approved for under building installation.

2. Protect the water pipes passing under sewers by providing a vertical separation of

at least 18” between the bottom of the sewer and the top of the water pipe.

3. Provide adequate structural support for the sewers to prevent excessive deflection

of the joints and settling on and breaking the water pipe. The length of water piping

shall be centered at the point of crossing the sewer pipe so that the joints will be

equidistant from the crossing.

3.03 STERILIZATION

A. Sterilize each completed portion of the water pipe installation with chlorine before use for

domestic purposes.

B. The materials used may be either liquid chlorine conforming to AWWA B301 or

hypochlorites conforming to AWWA B300.

C. The amount of dosage shall provide a minimum of 50 parts per million of chlorine. The

chlorine solution shall remain in the pipe for a maximum of 24 hours before the system is

flushed. Open and close the valves in the mains being sterilized a minimum of three times

during the contact period.

hydrostatic pressure of 150 pounds per square inch. The duration of each such test shall be

at least two hours.

B. Each section of pipe to be tested shall be filled with water and all air expelled at the highest

point. The required taps to expel air or to fill the water main shall be supplied and installed

by the Contractor and shall be ¾ inch and shall include an approved service saddle when

required.

The test apparatus shall be applied at the lowest elevation on the section to be tested. The

apparatus shall be connected to the pipe at a service tap or special tap location.

The pressure gauge shall be a standard pressure gauge. The dial shall register from 0 – 200

psi and have a dial size of 4 ½ inches with 1 psi increments.

The hydrostatic test, pressure requirement for an acceptable test shall be a maximum

pressure drop of 0 psi during the two hour pressure test.

If this test requirement cannot be met, the Contractor shall investigate the cause, make

corrections, and retest until the pressure drop requirement can be met.

Only if several consecutive tests indicate a consistent pressure drop and only after the

Contractor has made numerous attempts to resolve the problem, acceptable to the

Engineer, may the Contractor request in writing and the Engineer consider the use of the

leakage test. The leakage test may be performed by the Contractor to determine the

magnitude of the leak. However, meeting the leakage allowance shall not automatically be

considered acceptance, in lieu of the pressure test, for the section being tested. Final

acceptance shall be at the discretion of the Engineer.

When allowed, the leakage test shall be performed in accordance with AWWA C-600,

Section 4.1.5, 4.1.6 and the line will be accepted as per Section 4.1.7.

3.05 ELECTRICAL CONDUCTIVITY TESTS

A. The contractor shall perform a conductivity test within one week upon completion of

pressure testing on the pipe to establish that electrical locating of the line may be carried

out in the future.

3.06 CLEANING

A. Upon completion of the installation of the water piping and appurtenances, remove excess

materials, equipment, temporary structures, and debris resulting from the construction

work.
