PART 1 GENERAL

1.1 REFERENCES

The publications listed below form a part of this specification to the extent referenced. The publications are referred to within the text by the basic designation only.

ASTM INTERNATIONAL (ASTM)

IEEE/ASTM SI 10 (2002) American National Standard for Use of the International System of Units (SI):

The Modern Metric System

1.2 GENERAL

This project includes metric units of measurements. The metric units used are the International System of Units (SI) developed and maintained by the General Conference on Weights and Measures (CGPM); the name International System of Units and the international abbreviation SI were adopted by the 11th CGPM in 1960. A number of circumstances require that both metric SI units and English inch-pound (I-P) units be included in a section of the specifications. When both metric and I-P measurements are included, the section may contain measurements for products that are manufactured to I-P dimensions and then expressed in mathematically converted metric value (soft metric) or, it may contain measurements for products that are manufactured to an industry recognized rounded metric (hard metric) dimensions but are allowed to be substituted by I-P products to comply with the law. Dual measurements are also included to indicate industry and/or Government standards, test values or other controlling factors, such as the code requirements where I-P values are needed for clarity or to trace back to the referenced standards, test values or codes.

1.3 USE OF MEASUREMENTS IN SPECIFICATIONS

Measurements in specifications shall be either in SI or I-P units as indicated, except for soft metric measurements or as otherwise authorized. When only SI or I-P measurements are specified for a product, the product shall be procured in the specified units (SI or I-P) unless otherwise authorized by the Contracting Officer. The Contractor is responsible for all associated labor and materials when authorized to substitute one system of units for another and for the final assembly and performance of the specified work and/or products.

1.3.1 Hard Metric

A hard metric measurement is indicated by an SI value with no expressed correlation to an I-P value. Hard metric measurements are often used for field data such as distance from one point to another or distance above the floor. Products are considered to be hard metric when they are manufactured to metric dimensions or have an industry recognized metric designation.

DOCUMENT 00 31 10 Page 1

1.3.2 Soft Metric

a. A soft metric measurement is indicated by an SI value which is a mathematical conversion of the I-P value shown in parentheses (e.g. 38.1 mm (1-1/2 inches)). Soft metric measurements are used for measurements pertaining to products, test values, and other situations where the I-P units are the standard for manufacture, verification, or other controlling factor. The I-P value shall govern while the metric measurement is provided for information.

b. A soft metric measurement is also indicated for products that are manufactured in industry designated metric dimensions but are required by law to allow substitute I-P products. These measurements are indicated by a manufacturing hard metric product dimension followed by the substitute I-P equivalent value in parentheses (e.g., 190 x 190 x 390 mm (7-5/8 x 7-5/8 x 15-5/8 inches)).

1.3.3 Neutral

A neutral measurement is indicated by an identifier which has no expressed relation to either an SI or an I-P value (e.g., American Wire Gage (AWG) which indicates thickness but in itself is neither SI nor I-P).

1.4 COORDINATION

Discrepancies, such as mismatches or product unavailability, arising from use of both metric and non-metric measurements and discrepancies between the measurements in the specifications and the measurements in the drawings shall be brought to the attention of the Contracting Officer for resolution.

1.5 RELATIONSHIP TO SUBMITTALS

Submittals for Government approval or for information only shall cover the SI or I-P products actually being furnished for the project. Submit the required drawings and calculations in the same units used in the contract documents describing the product or requirement unless otherwise instructed or approved. Use IEEE/ASTM SI 10 as the basis for establishing metric measurements required to be used in submittals.

E3005 ANALYSIS REQUIREMENTS

E3005.1 ANNUAL ENERGY COST ANALYSIS

Not applicable

E3005.2 HVAC SYSTEM SELECTION

The Design/Builder shall implement the conversion of five existing flue gas boilers from steam to District Heating Hot Water, the design and construction of a backup steam to District Heating Hot Water Station, the design and construction of base District Heating Hot Water distribution piping, and the conversion of selected existing

SECTION 01 10 10 Page 14 buildings from steam to District Heating Hot Water. The design builder shall analyze, select, propose, design, and construct a mechanical HVAC system satisfying the performance requirements and goals listed herein.

It is the overall intent of this project to:

1. Maximize the potential production of heating hot water by the converted flue gas boilers.

2. Provide protection against system failure by providing a backup steam to district Heating Water conversion station.

3. To provide a system of distribution piping which shall both distribute the district Heating Hot Water to the affected buildings listed in this Request for Proposal and provide a distribution backbone for future production of heating hot water elsewhere on Thule Air Base.

4. To convert selected buildings from steam to District Heating Hot Water. In general, it is the intent to replace existing steam based equipment with the equivalent replacement in-kind by heating hot water equipment. Where the design builder can meet the space heating or domestic hot water needs of the building use by an alternative method, this possibility is open to the design builder where functional equivalence can be demonstrated and there is no additional cost to the Government.

E3005.3 HVAC LOAD ANALYSIS

It is expected that there are very limited circumstances where heating loads analyses must be performed. Where necessary, those loads analyses shall conform to these requirements. The HVAC loads calculations shall be performed with computer software capable of calculating each zone’s peak heating load as well as the whole building “block” loads.

The software shall, at a minimum, calculate outside air loads (sensible and latent) from ventilation and infiltration, and heat losses through fenestration, walls, floors and roofs. The heating load calculations must be performed without credit for occupants and internal gains.

HVAC load calculations shall be submitted to the Government for review and approval. Load calculation reports shall include all input and output used in the heating and cooling calculation program, and shall include zone peak heating loads results, and whole building “block” loads, air-handling unit coil selections, and psychrometric process charts.

E3005.4 SYSTEM SELECTION QUALIFICATIONS

BOILER CONVERSIONS

Conversion of Boilers B3, B4, and B5 is the first priority of the project. Conversion of Boilers B1 and B2 shall follow. This is done as a combination of work by Danstoker, the original manufacturer (or approved and qualified contractor) and Design Builder. The performance of this will require close coordination between the contractor and M-plant operation.

Danstoker shall provide a warranty of performance and longevity for the converted boilers of 5 years.

The end result shall be non-condensing boilers with the same flue gas control dampers that are now in place. Return district heating water into the converted boilers shall be no lower than 60C. The system shall be designed to a District Heating Supply temperature of 85C and a minimum return temperature of 45C. A shunt pump shall be provided to recirculated boiler heating water supply back to boiler entering water to raise the temperature to 60C when required.

M-Plant boiler conversions shall be controlled by a modified Weithaupt control system. The existing Weithaupt system has been prepared on its manufacture for this conversion. This shall be tied into the overall M-Plant control system. The successful bidder, with Danstoker as its subcontractor or Danstoker qualified installer is responsible to commission the conversions and demonstrate proper operation. The contractor may provide a new steam to water heat exchanger or may salvage unit(s) from converted buildings, if the heat exchangers are less than ten years old.

Auxiliary steam to water District Heating Water shall be required.

Implement the following:

1. Boiler Water Side Modifications

a. Demolish steam connections:

Demolish the existing steam lines and valves from the boiler outlet flange to the steam header flange. Provide new blind flanges on the abandoned boiler steam exit nozzle and the abandoned steam header connection to maintain system integrity for the remaining boilers.

b. Demolish feedwater connections:

Demolish the existing feedwater lines and valves from the boiler feedwater inlet flange to the feedwater header connection, including the feedwater control valve. Provide new blind flanges on the boiler connection and the

SECTION 01 10 10 Page 16 feedwater header connection to maintain system integrity for the remaining boilers.

c. Demolish boiler water level controls:

Demolish the existing water level controls used for steam service to the existing boiler flange points. Provide new blind flanges on the boiler connection points. Demolish electrical connections to the field terminal strip in the Boiler Control System cabinet.

d. Connect district hot water piping to the boiler Remove existing blind flanges from the existing hot water connection flanges of each designated boiler and attach the district hot water piping to these inlet and outlet connections with flanges and gaskets to match the existing designated boiler nozzles.

e. Other boiler water side appurtenances shall remain

2. Boiler Gas Side Modifications

a. The contractor shall verify the existing flue gas bypass damper actuators are functional and of sufficiently rapid response and torque capability to modulate for water temperature control plus limiting engine backpressure to no more than 38 millibars above atmospheric pressure.

b. See Boiler Operating Controls section for further requirements.

3. District Heating Water System Modifications

a. The district water system attaching to the three existing boilers being converted from steam.

b. The district heating system extension shall conform to the diagram shown below, with the exception that where the diagram indicates two District Heating Pumps three pumps sized at 50% each shall be provided:

SECTION 01 10 10 Page 17

See section E3060 Energy Management and Control Systems for boiler operating controls.

DISTRICT HEATING HOT WATER DISTRIBUTION

Pumping for District Heating hot water shall be from a single location in M-Plant. There shall be three pumps, each sized for 50% of the load. Pumps shall have variable frequency drives. Pumping shall be based on differential pressure at the most demanding point in the system. Provide pressure sensors in a sufficient number of locations in the system to determine required pump operation at all expected operating conditions among the buildings served.

Exterior pipe distribution shall be divided into two types; “backbone” piping, and “branch” piping. Backbone piping shall be sized to accommodate the eventual installation of a district heating loop in the center portion of the base and described on plans. Pipe size requirements are described in Attachment AA.

The contractor may investigate the possibility of combining the hot water from the exhaust boilers with existing heating distribution from the cooling engine jacket water. Please refer to appendix T for schematic of the distribution. If combining the two hot water sources does not pose any harm to the operation of the engine (will require verification from company knowledgeable working with these types of systems) the government may allow the design to progress in that direction after thorough discussion at the design kickoff.

Building Conversions

Buildings shall be converted from the existing steam service to district heating hot water. Existing base standard system details are used as guiding principles for the conversion. They shall be adapted
