STATEMENT OF WORK

INSTALL ON-DEMAND DOMESTIC HOT WATER SYSTEM

PROJECT 4A9R

SUMMARY OF WORK:

MCC Chicago is a 26 story high rise structure located at 71 W. Van Buren Chicago, IL. Adjacent to the high rise is an 8 story parking structure. Inside the parking structure is the power plant where all the domestic hot water is generated. The scope of this project is to completely replace the domestic hot water system and update the BAS to efficiently operate and log the new hot water system. Provide a turn-key installation of a packaged Instantaneous Double Walled Water Heater Assembly with all the valves, fittings, pipes, insulation, electrical, and BAS updates to function. All work and installations will be made in accordance with federal, state and local building codes and shall include all needed permits.

PART 1 SCOPE OF WORK

Asbestos abatement - Remove the insulation from heat exchangers that may contain ACM according to the MCC Asbestos report dated January 2 1996. Which states only the 140 converter tested positive for ACM (20-25%amosite)

2 – 9’’ diameter by 8’ long heat exchangers (225 square feet each)

1 – 11’’ by 8’ long heat exchanger (250 square feet)

1 – 11’’ by 2’ long heat exchanger (40 square feet)

Demolition – remove all insulation, tanks, pipework, valves, traps, and heat exchangers w/ racks involved in current domestic hot water system.

Tanks – Remove two hot water storage tanks.

-13’ long by 5’ in diameter

-18’ long by 5’ in diameter

Converters –remove 6 domestic hot water converters

-Two 8’ long by 9’’ diameter

-One 8’ long by 11’’ diameter

-One 2’ long by 11’’ diameter

-Two small Leslie package heaters 2’ tall by 2’ wide

Pipe – Remove all current pipework involved with domestic hot water system

-250 linear feet of 4’’ Galvanized

-400 linear feet of 2’’ copper

-200 linear feet of 2 1/2’’ Black pipe (steam line)

-50 linear feet of 5’’ Black pipe (steam line)

-200 linear feet of 2’’ Black pipe (Condensate line)

Installation of Hot Water System – Furnish and provide turn-key installation of a packaged Instantaneous Double Walled Water Heater Assembly with all the valves, fittings, pipes, insulation, electrical, and BAS updates to function. It will provide sufficient hot water to accommodate a dual temp domestic hot water system at 250 GPM. One side at 180 degrees (which will be referred to as the 180 system) and the other at 140 degrees (which will be referred to as the 140 system). The 180 system demand is 90 GPM and the 140 system demand is 160 GPM. The Heater will produce 180 degree water and split to feed both systems. The 140 system will go through a redundant Digital Recirculation Valve(DRV) which will blend the water down to 140 Degrees.

Steam Line – There are 2 steam lines involved in this project. A 4’’ steam line that supplied steam to the Leslie heaters and a 5’’ steam line that provided steam to the Hot water converters.

– Reconfigure the old 4’’ Leslie steam line after the lines feeding the Leslie heaters have been removed.

This also feeds a pre heat coil for AHU S-6, so it has to have a proper drip leg and condensate line ran to the condensate system

– Reconfigure the old 5’’ converter steam line after the lines feeding the converters have been removed to feed the new Instantaneous Double Walled Water Heater Assembly with proper drip leg and condensate line ran to the condensate system.

Condensate Lines and traps – Install manufacturer recommended (new heater) traps with properly sized condensate lines.

-from 4’’ steam line, install proper drip leg, traps, and condensate line tied into condensate system

-from new water heater, install proper drip leg, traps, and condensate line tied into condensate system

Water Lines – Run all cold, supply, and return lines to the new Water Heater

-Run a new 4’’ copper line off the current house pumps in the boiler level up 2 floors to the Converter level to feed the DRV

Reconfigure the 140 system and 180 system Supply and Return (4 – 4’’ galvanized lines) to meet the requirements of the new Water Heater. Install a Di-Electric flange on all 4 lines with 4 new flanged Stainless Steel ball valves to isolate the building. Install 4’’ copper with 4’’ grooved copper fittings to the water heater and/or DRV. On the new 4’’ supply and return copper lines, install a four 4’’x4’’x 2’’ T with 2’’ threaded shutoff valve to drain the building

Insulation – Insulate all lines involved with the project

- The Tridium Niagara Framework or equivalent

The Niagara Framework® is a software platform that integrates diverse systems and devices regardless of manufacturer, or communication protocol into a unified platform that can be easily managed and controlled in real time over the Internet using a standard web browser. NiagaraAX resolves the challenges associated with open systems, integration and interoperability by integrating diverse systems and devices - regardless of manufacturer, or communication protocol - into a unified platform that is easily managed and controlled over the Internet. A scalable solution, NiagaraAX increases the functionality and value of “smart devices and systems” by connecting real time operational data to the people and systems that manage business enterprises.

NiagaraAX creates a common environment that connects to almost any embedded device imaginable. It models the data and behavior of the devices into normalized software components, providing a seamless, uniform view of device data to the enterprise via a wide variety of IP-based protocols, XML-based connectivity options, and open API’s. By transforming the data from diverse external systems into normalized components, NiagaraAX creates an architecture that provides substantial benefits over gateway-based integration.

Today, there are over 245,000 instances of the Niagara Framework deployed worldwide.

1.04 SYSTEM DESCRIPTION

A. The intent of this project is to retrofit existing obsolete supervisory controllers at the project site with an open web-based Building Automation System (BAS). Tridium was chosen as the building block for the new BAS for this project and shall be comprised of the following:

1. NiagaraAX JACE – The web-based JACE shall act as the building supervisory controller.

2. NiagaraAX Supervisor - The Supervisor serves real-time graphical information to standard web-browser clients and also provides server-level functions such as: centralized data logging, archiving, alarming, trending, master scheduling and system-wide database management. In addition, the Supervisor provides a comprehensive, graphical engineering toolset for application development.

B. Tridium NiagaraAX Compatibility Statement (NiCS): The BAS system provided must utilize an open access product licensing procedure. The Tridium AX system provided for this project shall be capable of connection and management by any other

Niagara based tools or systems without the need to modify the license. The means that the end user (owner) does not have to authorize changes to the Tridium AX license for another systems integrator to gain access to the system. The end user does need to have the necessary administrative user names and passwords which shall be provided to the owner upon completion of the project. The following is an explanation of the NiCS licensing

2. Station Compatibility In: This field is a list of brands that this local station will allow NiagaraAX data to come in from. Simply stated from the point of view of a JACE, “this is the list of brands that I can accept data from”. The license shall be set as follows: Station Compatibility In = All

3. Station Compatibility Out: This field is a list of brands that this local station will allow NiagaraAX data to be shared with. Simply stated, “this is the list of brands that I can share data with”. The license shall be set as follows: Station

Compatibility Out = All

4. Tool Compatibility In: This field is a list of brands that this station will allow to be connected to it for engineering of its application. Simply stated, “this is the list of brands that can engineer me”. The license shall be set as follows: Tool

Compatibility In = All

5. Tool Compatibility Out: This field is a list of brands that this tool is allowed to connect to and engineer. Simply stated, “this is the list of brands that I can engineer”. The license shall be set as follows: Tool Compatibility Out = All
