HSCG85-11-Q-P30KL3 Amendment 0001

1. The following change is made to a drawing in the solicitation:

WI 28: "Grey Water / Sewage Tank System, Install" Replace the Coast Guard Drawing 65 WYT 4808-005, Rev D, Arrg’t & Det for Sewage Retention Tank Piping System to the current revision Coast Guard Drawing 65 WYT 4808-005, Rev F, Arrg’t & Det for Sewage Retention Tank Piping System.

2. The following contractor question was received on 25 July 2011 and is answered below:

Question:

"I have a question regarding Work Item 23: Exterior Exhaust Vents, Renew:

- Item description of tasks makes no reference to replacement of fan unit. - Government furnished property states NONE

- Item description references drawing and notes to complete work per drawing (65B WYT 3801-1) which calls for replacement of fan with a new fan and adapter spool.

I want to ensure that the intent is to follow this drawing and provide contractor furnished fan so that my price is not inconsistent with actual required scope. Please let me know if the scope is to include the fan, as noted in referenced drawing/installation notes."

Answer:

WI 23: "Exterior Exhaust Vents , Renew" Use Coast Guard Drawing 65B-WYT 3801-1, Rev -, Vent Sys Arrgt (65607-12) Sheet 1 ONLY, DO NOT USE the entire 65B WYT 3801-1 Drawing as reference per Initial Spec; to clarify not to replace the fan with a new fan and adapter spool ONLY to crop out the vent closure.

3. The following contractor question was received on 25 July 2011 and is answered below:

Question:

“I am missing referenced specification for work item 11: SFLC Std Spec 5100 Clean Shipboard Ventilation System.

Could you please provide this document?”

Answer:

The specification was inadvertently not included on the drawing CD. The specification is provided.

4. The two changed drawings and missing specification are attached.

5. Please submit any questions or comments for our response no later than 1600PT 28 July 2011. Any inquires received after the above deadline may or may not be responded to at the discretion of the Coast Guard.

6. There is no change to the proposal closing date, which remains as follows:

3. REQUIREMENTS

3.1 General.

3.1.1 Interferences. The Contractor shall be aware that interferences in way of work include, but are not limited to the below-listed, in addition to what may be listed in the invoking work item. Handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences).

• Vent system intake and exhaust screens.

• Vent system access covers.

3.1.2 Protective measures. The Contractor shall refer to paragraph 3.3.3 (Vessel component, space, and equipment protection) of SFLC Std Spec 0000, for the protection of equipment and machinery in the immediate area of the vent system access covers and screen removals, to prevent contamination while vent cleaning work is in progress.

3.2 Operational test - initial. Prior to commencement of work, the Contractor shall witness an operational pre-test (by Coast Guard personnel) of the designated vent system(s), to demonstrate existing operational condition. Document the system flow rate (in cubic feet per minute) at each intake and exhaust location while the system is operating. Submit a CFR.

Jan 2009 1 5100

3.3 Preparation.

3.3.1 Temporary ventilation. The Contractor shall provide adequate temporary ventilation to each compartment that is affected by shipboard ventilation ductwork cleaning or by securing associated fans, in accordance with the requirements of paragraph 3.3.1.1 (Temporary ventilation) of SFLC Std Spec 0000.

3.3.2 Marking. The Contractor shall mark the positions of all dampers and any air-directional mechanical devices within the vent system(s) before cleaning; return the settings to their marked positions upon completion of ventilation cleaning.

3.4 Cleaning requirement particulars. The Contractor shall accomplish the following tasks, for each designated vent system:

3.4.1 Preparation. Remove all vent access covers or sections of ductwork, as necessary, to allow complete access to all internal surfaces of the designated vent ductwork(s) and associated equipment.

3.4.2 Mechanical cleaning -general. Employ suitable mechanical means to clean all interior surfaces of the vent ductwork system(s), including removed intake and exhaust screens, access covers, and all internal associated equipment, to a condition free from dirt, grease, lint, impurities, and any other foreign matter. Clean the vent system(s) in its entirety from the point where the air enters the system to the point where the air is discharged from the system.

3.4.2.1 Remove all vent system access covers or remove sections of ductwork as required, to completely clean all vent interior surfaces. Vacuum the ductwork using a brush-type vacuum attachment.

3.4.2.2 Wipe down the vent system fan blades and vacuum the fan motor exterior, to remove accumulated dirt.

3.4.2.3 Vacuum and inspect dampers and venturi tubes to ensure there are no obstructions to restrict airflow.

3.4.2.4 Clean, inspect, lubricate, and exercise all directional closures and other vent fittings to ensure smooth operation.

3.4.2.5 Scrub with hot soapy water to remove the grease, and thoroughly dry vent ducts found to have grease accumulation. If vent ducts are inaccessible, remove first the section closest to the grease contamination source. Remove other sections as required to complete cleaning of all grease-contaminated vent ducts.

CAUTION!

If vent ducts are scrubbed in place, ensure water does not damage the surrounding area and equipment.

3.4.3 Coil cleaning. When cleaning heat or cooling coils, avoid using any method that might force contaminants further into the coils. After completion of cooling coil cleaning, wash the coils, condensate tubes, and drip pans with a suitable sanitizing agent.

NOTE

Use of a vacuum collection method is considered appropriate for coil cleaning.
