    Y:\1-Technical\2831 BOPU\06 Sherard Hydropower\Bidding\Powerhouse and Installation\Re-Bid\Addendum\Addendum 2\Addendum #2_1-20-2021.docx

    Response: See specification Section 13850 – Fire Alarm and Control System

    attached to this Addendum.

    Question #2: Is Flexion XL Single Ply Copolymer-Alloy Membrane Roofing, “Flexion

    XL”, manufactured by Conklin Company Inc. an approved equal PVC

    roof membrane?

    Response: Flexion XL Single Ply Membrane manufactured by Conklin Company

    Inc. is an approved PVC roof membrane as long as this product

    complies with the Specifications and Drawings.

    Question #3: On drawing Sheet E1 R3 it shows the proposed precast concrete trench

    cable tray that runs from the new hydro building to the existing WTP

    electrical room. Would an alternate of an approved duct bank with PVC

    conduit with spare conduits encased in concrete be allowed for the

    project instead of the precast concrete trench?

    Response: While a concrete encased conduit is allowable per NEC and is a

    standard type of installation, the details of the duct bank are

    dependent on several factors (depth, conduit type, concrete thickness,

    thermal performance, etc.) and could be a value engineering option.

    The precast concrete trench cable tray was selected for reduced depth

    requirements to avoid interference with other utilities. Concrete

    encased duct bank in lieu of concrete trench cable tray is not allowed

    as a substitution for bidding. The Owner may consider a value

    engineering proposal after award.

    Question #4: In the pre-bid meeting, it was mentioned that electronic bids are

    acceptable, but the bonding documents will need to be mailed. Is this

    correct?

    Response: See Article 15 of the Instructions to Bidders. A hard copy of the

    complete bid (including bonds) with original signatures is still required

    if submitted electronically and should be postmarked on or before the

    Bid Opening date. Please note, Bidder is responsible for verifying

    receipt of the bid.

    Question #5: How many iFix nodes will need programmed?

    Response: There is only one node to program. The water treatment plant iFix

    SCADA system server only needs programed once. All nodes receive

    information from the server. Also, see specification Section 11200 –

    Owner Supplied Equipment for a list of Hydro PLC tags that will need

    to be programed in the existing Water Treatment Plant iFix SCADA

    system.

    Question #6: Ethernet communications to devices will be through Modbus TCP. Is

    the existing SCADA PLC setup for Modbus TCP? Is the Hydro PLC setup

    for Modbus TCP?

    Y:\1-Technical\2831 BOPU\06 Sherard Hydropower\Bidding\Powerhouse and Installation\Re-Bid\Addendum\Addendum 2\Addendum #2_1-20-2021.docx

    Response: The BOPU is currently using ABR I/O Driver and OPC Client Driver to

    communicate with existing PLC’s in BOPU’ system. Bidders can use

    either system when configuring communication setup. See

    specification Section 11200 – Owner Supplied Equipment for details on

    the Hydro PLC setup.

    Question #7: Drawing Sheet I1 Note 13 says Contractor is responsible for any

    communication expansion/conversion components. How much space is

    there currently in the existing ethernet switch for rj45 and sc fiber

    connections? Is there room in the existing cabinet for the extra patch

    panels and a new switch?

    Response: Note 13 on Sheet I1 is for hard wired physical signals and are not

    intended to be transmitted over the existing WTP SCADA system to the

    Hydro Control Panel. That said, there are a lot of spare rj45 spaces

    available in the existing ethernet switch. Contractor will need to

    provide a wire fiber converter which will connect to the existing rj45

    switch. Yes, there is room in the existing cabinet for the extra patch

    panels and new switch. A 19-inch rack system is currently installed.

    See specification Section 16760.

    Question #8: Specification Section 02960 requires joint coating repair at all field

    weld joints. Per specification Section 01042 there is a limited time to

    perform tie-ins. The recommended cure time for the specified

    polyurethane may exceed the required water treatment plant

    shutdown times.

    Response: TNEMEC FC22 may be used as a fast cure joint repair coating. This

    product is NSF-61 certified. This product under the right conditions

    can be returned to service in 16 hours. Joints may need to be repaired

    during the second plant shut down. Prep and application of this

    product shall be in accordance with the manufacturer

    recommendations.

    Question #9: Is there any temporary electrical service needed for circuits in the

    concrete encased duct bank re-route at the 48” tailrace pipe (low

    pressure valve vault) tie-in area?

    Response: The existing concrete encased electrical and control duct banks at the

    48” tailrace pipe (low pressure valve vault) tie-in area shown on Sheet

    C8 and C10 are empty except for 2-#8, 1-#8 GRD conductors which

    supply power to the luminaires near the proposed powerhouse. These

    luminaires do not require temporary service while the duct bank is

    being removed and re-routed. Replace the 2-#8 CU, 1-#8 GRD,

    XHHW-2 conductors and splice in the existing electrical manholes. The

    duct bank length between the existing electrical manholes with the

    Note: Executive Order (EO) 13706, Establishing Paid Sick Leave

    for Federal Contractors applies to all contracts subject to the

    Davis-Bacon Act for which the contract is awarded (and any

    solicitation was issued) on or after January 1, 2017. If this

    employees with 1 hour of paid sick leave for every 30 hours

    they work, up to 56 hours of paid sick leave each year.

    Employees must be permitted to use paid sick leave for their

    own illness, injury or other health-related needs, including

  • preventive care; to assist a family member (or person who is

    like family to the employee) who is ill, injured, or has other

    health-related needs, including preventive care; or for reasons

    resulting from, or to assist a family member (or person who is

    is available at www.dol.gov/whd/govcontracts.

    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 a union rate (current union negotiated rate for local),

    a survey rate (weighted average rate) or a union average rate

    (weighted union average rate).

    Union Rate Identifiers

    A four letter classification abbreviation identifier enclosed

    in dotted lines beginning with characters other than ""SU"" or

    ""UAVG"" denotes that the union classification and rate were

    prevailing for that classification in the survey. Example:

    PLUM0198-005 07/01/2014. PLUM is an abbreviation identifier of

    the union which prevailed in the survey for this

    classification, which in this example would be Plumbers. 0198

    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. 07/01/2014 is the effective date of the

    most current negotiated rate, which in this example is July 1,

    2014.

    Union prevailing wage rates are updated to reflect all rate

    changes in the collective bargaining agreement (CBA) governing

    this classification and rate.

    Survey Rate Identifiers

    Classifications listed under the ""SU"" identifier indicate that

  • no one rate prevailed for this classification in the survey and

    the published rate is derived by computing a weighted average

    rate based on all the rates reported in the survey for that

    classification. As this weighted average rate includes all

    rates reported in the survey, it may include both union and

    non-union rates. Example: SULA2012-007 5/13/2014. SU indicates

    the rates are survey rates based on a weighted average

    calculation of rates and are not majority rates. LA indicates

    the State of Louisiana. 2012 is the year of survey on which

    these classifications and rates are based. The next number, 007

    in the example, is an internal number used in producing the

    wage determination. 5/13/2014 indicates the survey completion

    date for the classifications and rates under that identifier.

    Survey wage rates are not updated and remain in effect until a

    new survey is conducted.

    Union Average Rate Identifiers

    Classification(s) listed under the UAVG identifier indicate

    that no single majority rate prevailed for those

    classifications; however, 100% of the data reported for the

    classifications was union data. EXAMPLE: UAVG-OH-0010

    08/29/2014. UAVG indicates that the rate is a weighted union

    average rate. OH indicates the state. The next number, 0010 in

    the example, is an internal number used in producing the wage

    determination. 08/29/2014 indicates the survey completion date

    for the classifications and rates under that identifier.

    A UAVG rate will be updated once a year, usually in January of

    each year, to reflect a weighted average of the current

    negotiated/CBA rate of the union locals from which the rate is

    based.

    ----------------------------------------------------------------

    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.
