x (Rev-1)

3.5 Interim changes and additions to SFLC Std Spec 0000. The Contractor shall be aware of the following interim changes and additions to the 2009 Edition of SFLC Std Spec 0000:

3.5.1 Acronyms and term definitions – paragraph 1.3 (Acronym and term definitions).

3.5.1.1 The term “COTR” has been replaced with “COR”, which is defined as follows:

“COR”: Contracting Officer’s Representative – the person delegated by the KO as the on-scene representative for matters concerning performance of work; this includes correctness, timeliness, and quality of the Contractor’s work. Normally, the CO/OINC is designated the COR.”

3.5.1.2 Definition addition for the term “Ungrounded, as follows:

• “Ungrounded”: A power system where all of the current-carrying conductors and windings

(including any neutral connection) are insulated from ground. In contrast, a generator or transformer in which at least one conductor or point (usually the midpoint or corner of a delta winding or the common center of a wye winding) is intentionally grounded, either solidly or through an impedance, is considered grounded. Note that the distinction concerns only current-carrying conductors; for both ungrounded and grounded power systems, non-current carrying metal parts and equipment grounding conductors are always bonded to earth ground for personnel safety. At non-Governmental facilities, dockside wye connected transformer secondary windings are almost always grounded and are generally not suitable for connection to a Coast Guard cutter without a separate Contractor furnished isolation transformer.”

3.5.2 Changes to paragraph 3.2.4 2.3 (QP-1 Inspector or Tech Rep duties).

“3.2.4.2.3 QP 1 Inspector or Tech Rep duties.

3.2.4.2.3.1 The Coating Inspector for the “QP 1-certified” Contractor or the Contractor-provided NACE-certified Tech Rep shall remain on site, to perform the following duties, as applicable, for each work item that involves preservation of “critical-coated surfaces”:

• Verify inspection instrument calibration.

• Verify and approve the suitability of ambient conditions before surface preparation is begun, and before each coat of paint is applied.

• Verify all aspects of surface preparation – including, but not limited to:

o Cleanliness of compressed air.

o Adequacy of solvent cleaning.

o Proper handling of blast media.

o Actual surface preparation procedure.

• Inspect and approve final surface preparation, before application of primer coat.

• Supervise and approve coating system preparation and application procedures, including but not limited to: mixing and thinning, stripe coating application, spray techniques, and film thickness measurements and recordings.

• Determine when applied coats have sufficiently cured for overcoating, or for system service resumption (see paragraph A2.1.18 (Critical drying time requirements)).

• Complete and sign the quality assurance (QA) inspection forms (see QA-1 thru QA-5), provided in Appendix A (Requirements for Preservation of Ship Structures) of this document.

• Submit all completed QA inspection forms to the COR (through the Contractor), upon xi (Rev-1) completion of work.

3.2.4.2.3.2 The Contractor shall ensure the NACE Inspector is formally informed - via suitable subcontract documentation- and is willing and able to perform of all duties listed above. Submit documentation of this contract and assumption of duties to the KO at the Arrival Conference.”

3.5.3 Changes to contents of paragraph 3.2.5 (Planning document).

“3.2.5 Planning document. The Contractor shall generate a legible Planning Document (PD) with the following characteristics:

• Graphical in format (see Fig. 1 (Sample Planning Document Submittal)).

• Shows overall period of performance for each CLIN, with start and stop dates of major sub-tasks.

• Contains due dates for Critical Inspection Reports (CIR) and any events requiring Coast

Guard Inspector presence.

• Identifies all work item time periods that require OEM Tech Rep assistance.

• Identifies the “critical paths” for the project.

• Shows calculations for the “float” along the critical paths and labels the critical paths with the number of delay days the critical paths can absorb without affecting the final delivery date.

NOTE

Float is the number of days that the critical paths can be delayed without affecting the final delivery date.

3.2.5.1 Ensure that the PD also includes the names, contact information, and written commitment from all Tech Reps required by the Contract - indicating they are available for work during the proposed time period.

3.2.5.2 Submit a preliminary electronic copy of the PD to the COR - for Government review - no later than one week after contract award.

3.2.5.3 Submit 3 copies of the PD to the COR, 15 days prior to the start of the performance period, and at all weekly Progress Meetings.

2. The reverse side of the test coupon may be used for the subsequent test, provided that the conditions in paragraph A2.1.7.4 (Coupon test) are met.

A2.1.7.4.3 Repeat the abrasive blasting operation test in the following instances:

• The setup, as defined in paragraph A2.1.7.4.1 is changed.

• The resultant anchor profile readings observed on the vessel are outside the specified anchor profile range.

• Media is changed from MIL-A-22262 to CID A-A-59316 or vice versa.

• The supplier of the abrasive blasting media changes, regardless if the new source for the media has the same specifications.

• When Directed by the COR.

NOTE

A performance test of the abrasive blasting operations on a test coupon and measuring the anchor profile prior to performing the operation on the cutter, in order to confirmed that the anchor profile range that the operation is going to produce. An abrasive blasting operation test is prudent, as there are enough variables in the equipment setup and media properties that the resulting anchor profiles from one contractor to the next vary significantly.

3.5.11 Post-surface preparation requirements - additional to paragraph A2.1.8 (Post-surface preparation requirements).

A2.1.8.8 Substrate profile measurements - during and post-surface preparation. In order to ensure production of required surface profile, the Contractor shall accomplish the following tasks, whenever abrasive-blasting is required in a work item for complete preservation of a ”critical-coated” surface:

xvi (Rev-1)

A2.1.8.8.1 During surface preparation by abrasive blasting or waterjetting operations, spot check the existing anchor profile per 500-square feet, in order to 'project' the need to manage the excessive anchor inspect for both excessive and insufficient anchor profiles . When the Contractor elects to prepare a substrate by waterjetting, the Contractor shall inspect the substrate for areas of insufficient or excessive anchor profile, both visually and in accordance with ASTM D4417, Method A or C. Submit a CFR detailing the location, square footage, measured anchor profiles, and the anchor profile range required for the applicable coating system.

A2.1.8.8 2 Post completion of surface preparation, measure the profile of the resultant bare surfaces, in accordance with ASTM D4417, Method A or C.”

3.5.12 Caution verbiages – additional to paragraph A2.1.18 (Critical drying and cure time requirements).

“CAUTIONS!

1. Hard cure times or cure time prior to immersion for any “critical coated system” shall be met as published on the Product Data Sheets available online. No early undocking or relaxation of these published requirements is permitted without prior approval from the KO. Coating system manufacturer’s Sales or Technical Representatives may not relax these requirements. Painting and curing of all tank coating systems (except for tanks that are inboard and not touching the skin of the vessel (side and/or bottom) shall occur while the cutter is out of the water.

2. CAPAC systems shall not be energized until full cure of all underwater paint systems has occurred.”

3.5.13 Preservation Plan.

“A2.2 Preservation Plan (PP). The contractor shall submit a PP to the COR at the arrival conference, to allow for review of all work items pertaining to the preservation of the vessel. At a minimum, PP shall include the following and be broken down by work item:

• Coatings to be applied – listed by manufacturer and product identification numbers.
