Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (ii)).

The body of each wage determination lists the classification and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination. The classifications are listed in alphabetical order of "identifiers" that indicate whether the particular rate is union or non-union.

Union Identifiers

An identifier enclosed in dotted lines beginning with characters other than "SU" denotes that the union classification and rate have found to be prevailing for that classification. Example: PLUM0198-005 07/01/2011. The first four letters , PLUM, indicate the international union and the four-digit number, 0198, that follows indicates the local union number or district council number where applicable , i.e., Plumbers Local 0198. The next number, 005 in the example, is an internal number used in processing the wage determination.

The date, 07/01/2011, following these characters is the effective date of the most current negotiated rate/collective bargaining agreement which would be July 1, 2011 in the above example.

Union prevailing wage rates will be updated to reflect any changes in the collective bargaining agreements governing the rates.

0000/9999: weighted union wage rates will be published annually each January.

Non-Union Identifiers

Classifications listed under an "SU" identifier were derived from survey data by computing average rates and are not union rates; however, the data used in computing these rates may include both union and non-union data. Example: SULA2004-007 5/13/2010. SU indicates the rates are not union majority rates, LA indicates the State of Louisiana; 2004 is the year of the survey; and 007 is an internal number used in producing the wage determination. A 1993 or later date, 5/13/2010, indicates the classifications and rates under that identifier were issued as a General Wage Determination on that date.

Survey wage rates will remain in effect and will not change until a new survey is conducted.

WAGE DETERMINATION APPEALS PROCESS

1.) Has there been an initial decision in the matter? This can be:

* an existing published wage determination

* a survey underlying a wage determination

* a Wage and Hour Division letter setting forth a position on a wage determination matter

* a conformance (additional classification and rate) ruling

On survey related matters, initial contact, including requests for summaries of surveys, should be with the Wage and Hour Regional Office for the area in which the survey was conducted because those Regional Offices have responsibility for the Davis-Bacon survey program. If the response from this initial contact is not satisfactory, then the process described in 2.)

and 3.) should be followed.

With regard to any other matter not yet ripe for the formal process described here, initial contact should be with the Branch of Construction Wage Determinations. Write to:

Branch of Construction Wage Determinations Wage and Hour Division U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

2.) If the answer to the question in 1.) is yes, then an interested party (those affected by the action) can request review and reconsideration from the Wage and Hour Administrator (See 29 CFR Part 1.8 and 29 CFR Part 7). Write to:

Wage and Hour Administrator U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

The request should be accompanied by a full statement of the interested party's position and by any information (wage payment data, project description, area practice material, etc.) that the requestor considers relevant to the issue.

3.) If the decision of the Administrator is not favorable, an interested party may appeal directly to the Administrative Review Board (formerly the Wage Appeals Board). Write to:

Administrative Review Board U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

4.) All decisions by the Administrative Review Board are final.

1.6 TERMS

In some instances, terminology differs between the Contract and the

SECTION 01 91 00 Page 5

Commissioning Standard primarily because the intent of this Section is to use the industry standards specified, along with additional requirements listed herein to produce optimal results. Contract requirements take precedent over the corresponding ACG, NEBB, BCA or TABB requirements where differences exist.

a. "Acceptable Performance" is a component or system being able to meet specified design parameters under actual load including satisfactory documented completion of all functional performance tests, control system trending and resolution of outstanding issues.

b. "Basis of design" is the documentation of the primary thought processes and assumptions behind design decisions that were made to meet the design intent. The basis of design describes the systems, components, conditions and methods chosen to meet the intent. Some reiterating of the design intent may be included.

c. "Check out and test plans" is a test plan which includes equipment manufacturers published installation, start-up, and field acceptance test procedures.

d. "Commissioning (Cx)" is a comprehensive and systematic process to verify that the building systems perform as designed to meet Government requirements and the design intent, assure user training and O&M materials have been provided, and assure the entire process has been properly documented.

e. "Commissioning Plan" (Cx Plan) is an overall plan that provides the structure, schedule, and coordination planning for the Cx Process. The Construction Phase Cx Plan is appended to this specification. It shall be updated and finalized by the CxS and provided to all commissioning team members to inform them of the intent and scope of commissioning, facilitating the Cx process.

f. "Commissioning Report" (Cx Report) is prepared and maintained by the CxS and shall consist of completed Pre-Functional Performance Test Checklists (PC) and completed Functional Performance Tests (FPT) organized by system and by subsystem and submitted as one package. The Cx Report may also refer and rely on other documentation to include HVAC systems test reports, inspection reports, start-up reports, TAB report, TAB verification report, Controls start-up test reports and Controls Performance Verification Test (PVT) report. The results of failed tests shall be included along with a description of the corrective action taken.

g. "Data logging" records data such as flows, currents, status, and pressures over time using stand-alone data loggers separate from the control system.

h. "Deferred functional tests" are performed after substantial completion, due to partial occupancy, equipment, seasonal requirements, design, or other site conditions that disallow the test from being performed before substantial completion.

i. A "deficiency" is a condition in the installation or function of a component, piece of equipment, or system that is not in compliance with the Contract documents.

j. The "design intent" represents the ideas, concepts, and criteria that are conveyed through the Contract documents.

SECTION 01 91 00 Page 6

k. "Factory testing" tests equipment on-site or at the factory by factory personnel.

l. A "functional performance test" (FPT) test systems in such a manner to demonstrate the dynamic function and operation of equipment and systems under full operation using manual (direct observation) or monitoring methods. In this context, "function" includes all modes and sequences of control operation, all interlocks and conditional control responses and all specified responses to abnormal emergency conditions. The detailed functional performance tests will be prepared and witnessed by the CxS.

m. "Indirect indicators" indicate a response or condition, such as a reading from a control system screen reporting a damper to be 100 percent closed.

n." Issues Log" is used to provide a method for tracking and resolution of deficiencies discovered as a result of the commissioning process. This list also includes the current disposition of issues and the date of final resolution as confirmed by the CxS. The Issues Log will be created and managed by the CxS and integrated into the Contractor Quality Control System.

o. A "manual test" uses hand-held direct reading instruments, immediate control system readouts, or direct observation to verify performance (contrasted to analyzing monitored data taken over time to make the observation).

p. "Nonconformance" means a piece of equipment or a system does not perform properly or comply with the design intent.

q. An "overwritten value" is a sensor value in the building control system that is overridden to see the response of a system. For example, changing the outside air temperature value from 50 degrees F to 75 degrees F to verify economizer operation. See also "simulated signal."

r. "Phased commissioning" is completed in phases (by floors or buildings, for example) due to the size of the structures or other scheduling issues, in order to minimize the total construction time.

s. "Prefunctional Checklists" are detailed checklists prepared by the CxS.

Checklist shall be by system or equipment to verify installation and start-up of equipment is complete and ready for functional performance testing. PCs are primarily static inspections and procedures to prepare the equipment or system for initial operation (e.g., belt tension, oil levels OK, labels affixed, gages in place, sensors calibrated). However, some PC items entail simple testing of the function of a component, a piece of equipment or system (such as measuring the voltage imbalance on a three phase pump motor of a chiller system). PCs augment and are combined with the manufacturer's startup checklist. The completed checklists require signatures by the Contractor's Quality Control Manager and CxS prior to continuing with the commissioning process.

t. "Sampling" functionally tests only a fraction of the total number of identical or near identical pieces of equipment.

u. "Seasonal performance tests" are functional performance tests that are deferred until the system(s) will experience conditions closer to their design conditions.

SECTION 01 91 00 Page 7

v. "Simulated conditions" are created conditions for the purpose of testing the response of a system (e.g., applying a hair blower to a space sensor to see the response in a VAV box).

w. A "simulated signal" uses a signal generator to send an amperage, resistance or pressure to the transducer and DDC system to simulate a sensor value.

x. "Startup" includes the initial starting or activating of dynamic equipment and executing PCs.

y. " Systems Manual" is a system-focused composite document that includes the operation manual, maintenance manual, and additional information of use to the Owner during the Occupancy and Operations Phase. The Systems Manual shall provide the information needed to understand, operate, and maintain the systems and assemblies and to inform those not involved in the design and construction process about the systems and assemblies. The Systems Manual expands the scope of the traditional operating and maintenance documentation to include the additional information gathered during the Commissioning Process and to provide a systems-based organization of information.

z. "Test requirements" specify what modes, functions, and conditions shall be tested. The test requirements are not the detailed test procedures.

The test requirements are specified in the individual sections of the Contract documents.

aa. "Trending" uses the building control system for monitoring.

bb. The "warranty period" involves the entire project, including equipment components. Warranty begins at substantial completion and extends for at least one year, unless specifically noted otherwise in the Contract documents and accepted submittals.

1.7 CERTIFICATE OF READINESS

The GC shall issue a Certificate of Readiness certifying that the building energy systems are ready for Functional Performance Testing. The Certificate of Readiness shall include all equipment and system start-up reports, Performance Verification Test Reports, Pre-Functional Checklists, TAB Report, and the Building Air Tightness Test Report. The GC and the Mechanical, Electrical, Controls, and Testing, Adjusting, and Balancing Representatives shall sign and date the Certificate of Readiness.

3.4.1 Simulated Conditions

Over-writing values through the building control system is not acceptable, unless approved by the PE/COR. Proposed exceptions need to be identified and protocol submitted to the PE/COR for approval. Before simulating conditions, overwriting values (if approved), or changing set-points, sensors, transducers and devices shall have been calibrated. Below are several examples of exceptions that would be considered acceptable:

1. When "various" actual static pressures inside ductwork can not be simulated within the duct, and where a sensor signals the building control system to initiate sequences at various duct statics, it would be considered acceptable to simulate the various pressures via Pneumatic Squeeze-Bulb Type Signaling Device with gauge temporarily attached to the sensing tube leading to the transmitter. It would not be acceptable to reset the various set-points, nor to simulate an electric analog signal.

2. Dirty filter pressure drops can be simulated using sheets of cardboard at filter face.

3. Freeze-stat safeties can be simulated via packing portion of sensor with ice.

4. Increase in outside air temperature can be simulated at the sensor by heating with a blow dryer.

5. Changes in entering cooling coil conditions can be simulated using the preheat coil.

6. Using a signal generator to simulate a sensor signal is generally not recommended for commissioning, but may be proposed for special conditions.

7. Altering set points is acceptable to simulate certain conditions. For example, to see the AC compressor lockout work at an outside air temperature below 55 degrees F when the outside air temperature is above 55 degrees F, temporarily change the lockout set point to be 0 degrees F above the current outside air temperature. Caution: Set points are not to be raised or lowered to a point that would damage the components, systems, or the building structure and/or contents.

8. Duct Mounted smoke detectors to be tested per the detector manufacturer's recommendation using aerosolized smoke, and gauges on sampling tubes. Test to be done with air system at minimum airflow condition in ductwork.

9. Current sensing relays used for fan and pump status signals to BMS to indicate unit failure and run status are to be tested by resetting the trip point on the relay to a point simulating lost belt or unit failure, while the unit is running and confirming that the failure alarm was…
