Key changes include adding pipe cleaning and flushing procedures for the HVAC water treatment, updating the Siemens quote for instrumentation and control, and modifying drawing details for the air-cooled condensing unit foundation and mechanical schedules. The project involves installing a new air-cooled condenser and adding cooling coils to an existing air handling unit, with an alternate option to replace a chiller at the school gymnasium.

The addendum also includes substitution requests for air-cooled condensing units and DX coils, with approved manufacturers like Daikin, Temtrol, and York. The base bid includes an allowance of $28,460.25 for controls work, while Alternate #1 (chiller replacement) includes an allowance of $9,209.11 for controls work. The target substantial completion date is December 31, 2023, or August 31, 2024 if Alternate #1 is selected. The document provides detailed specifications for cleaning and flushing the chilled water system, including requirements for chemical treatment, velocity, alkalinity levels, and pH testing. Additionally, a Siemens proposal is included, with a total quote price of $35,875.58 with Alternate #1 and $27,105.00 without it.

Piping Systems Cleaning and Flushing Procedure

1.0 PURPOSE

The purpose of this checklist is to ensure that the piping system cleaning and flushing is completed per specification and is clearly documented.

2.0 SCOPE

Cleaning and flushing of the chilled water system.

3.0 PIPING SYSTEM CLEANING AND FLUSHING TEST PROCEDURE

General

Involve the chemical treatment supplier in furnishing the chemicals and testing the water after the pressure test.

Confirm system has been pressure tested and passed prior to flushing and cleaning of piping systems. Water or other fluid should not be entered into the system until factory cleaned devices are isolated from the system.

Confirm coils, control valves, heat exchangers, other factory-cleaned equipment, and any component that may be damaged or fouled during cleaning and flushing have been bypassed. Temporary piping or hose is acceptable.

Remove water filter elements from system before starting circulation.

Fill out Piping System Cleaning and Flushing Sign-Off Sheet.

After completion of test, replace filters, clean strainers and reconnect equipment and specialties that were bypassed.

Specific Procedures

Chilled Water

Use cleaning compound similar to Nalco 2567 to remove organic soil, hydrocarbons, flux, pipe mill varnish, pipe compounds, iron oxide, and like deleterious substances, with or without inhibitor, suitable for system metals without deleterious effects. Cleaner shall not contain phosphate.

Sectionalize system to obtain minimum velocity required by cleaning compound manufacturer – (normally 6 fps).

Piping systems shall be filled, vented and circulated employing chemical cleaner solution for period of at least 24 hrs or more in accordance with manufacturer’s recommendations and job site chemical tests. Bring concentration to level, which raises M Alkalinity to manufacturer's recommended value above that for existing water used for fill. Generally, M-Alkalinity is raised to 300 ppm or pH level of 9.0 for pipe cleaning. Conduct chemical tests to verify levels and record results.

Flush detergent clear with continuous draining and make-up water fill for period of at least 12 hrs or more until original M Alkalinity level is achieved (or until pH of system water is within 0.5 pH of make-up water). Conduct chemical tests to verify levels and record results. Cleaning solution may need to be neutralized, usually by mild acid solution to between a pH of 6 to 9 prior to discharge to the sanitary sewer. Check with the Owner or local utility concerning regulations on pH of discharge.

Inspect, remove sludge, and flush low points with clean water after cleaning process is completed.

After completion of cleaning a water system, system chemical treatment program should begin. Coordinate start of program with chemical treatment supplier.

Inspect, remove sludge, and flush low points with clean water after cleaning process is completed.

After completion of cleaning a water system, system chemical treatment program (i.e.

biocides and corrosion inhibitors) should begin. Coordinate start of program with chemical treatment supplier.
