EXHIBIT G – MILESTONE PROCESS FOR COMPETITIVE SOLICITATION NO. BFJ2023001 – 2 BRONZE STATUES Schedule 1 – Traditional Rubber Molds Schedule 1 Summary Table – with review, approvals and recommended payment stages (x7)

Schedule 1 Process Description Table

Replication process

Silicone rubber mold, with rigid support (e.g. reinforced plaster or fiberglass jacket)

Silicone Rubber Mold – includes labor, materials, travel expenses if necessary

Requirements:

1) Rubber must have a lifespan of no less than 5 years.

2) Rigid supports must be reinforced with fiber, hemp, or wire.

3) Registration keys and locks must be incorporated into the mold and rigid supports to ensure proper seating.

To be considered 100% complete, all rubber and rigid support sections need to be cured, separated, and removed from the clay statue. A tally of individual mold sections and number of individual patterns necessary to complete one statue must be provided to ArtsWA.

10%

Requirements:

1) Average pattern wall thickness must not be less than 1/8” thick, or greater than ¼” thick.

To be considered 100% complete, all patterns need to be ready to proceed to the slurry room, meaning they need to be sprued, gated, and core-pinned (if necessary). ArtsWA will review and accept patterns based on the quality of their replication and readiness for the next stage.

Total – 30%

Statue 1 (15%) Statue 2 (15%)

Requirements:

· Silicon bronze casting alloys CDA 873 (Everdur) or CDA 876 (Herculoy, 92-4-4).

· Ceramic shell and/or plaster investment casting processes are acceptable. Sand casting and other non-specified types of casting processes will not be considered acceptable without specific permission from ArtsWA.

To be considered 100% complete, all cast metal patterns must be 100% silicon bronze alloy, divested, sandblasted, core pins removed, sprues/gates removed, and ready for assembly. All individual patterns will be reviewed for quality and accepted by ArtsWA. Patterns with significant flaws such as (but not limited to) portions that didn’t fully cast or have excessive porosity, may not be accepted and replacement patterns may be required.

Total – 20%

Statue 1 (10%) Statue 2 (10%)

Requirements:

· All weld joins for windows and panel assembly must be a minimum of 1/8” thick. Cracked or thin welds will not be accepted.

· Casting flaws must be remedied, repaired, or filled such as (but not limited to) pin holes, pits, porous metal sections greater than 1 square inch, inclusions, and unwanted embedded materials.

· Panel seams and welded areas must not be recognizable as such.

· Bronze surface welding rod to match casting alloy as close as possible. Areas where welding rod coloration is visible or does not patina to the same color as the cast metal will be unacceptable.

· Stainless steel alloy for the mount and armature must be 304/304L.

· Stainless steel welding rod alloy for the mount and armature must be 308/308L.

· Mounting hardware provided by the foundry must be stainless steel 18-8 austenitic. (A set of four 9” x ½”-13 all thread rods with corresponding nuts, washers, and lock washers for each statue.)

· The statues must be sandblasted clean prior to final review.

· Successfully fit statues to the pedestal frames to ensure alignment.

To be considered 100% complete, the bronze casting, stainless-steel mount and stainless-steel armature assembly must be deemed acceptable by ArtsWA and ready for patina application. Approval of this phase will be determined upon review of the metal work such as (but not limited to) quality of assembly, planar alignment of panels, tooling/chasing, and appropriate texture.

Total – 34%

Statue 1 (17%) Statue 2 (17%)

Requirements:

· Statue must be sandblasted clean prior to start of the patination process.

· Patina color test plates will be created to determine the correct strength, warmth, shading, and intensity of the desired patina.

· Traditional brown patina (Liver and Ferric Nitrate) with burnished surfaces, painted sections with acrylic or enamel colors, sealants to include clear lacquers and/or clear carnauba paste wax.

· Basecoat chemical Liver of Sulfur must be sufficiently washed and neutralized during the patina application process. Alternative basecoat chemicals may be accepted upon approval by ArtsWA.

· Artist consultation, ArtsWA, and patineur to discuss desired outcome and process/materials prior to start and throughout the process.

To be considered 100% complete, the patina, color treatment, and sealant applications must be applied, cured, and/or buffed to ArtsWA’s satisfaction.

Statue 1 (3%) Statue 2 (3%)

ArtsWA expects to engage the artist for consultation and will draft a contract for his time and effort. The artist’s consultation will be limited to key points in the fabrication process and all artist feedback communication will be delivered through ArtsWA representatives. ArtsWA will oversee the completeness and quality of the bronze statue production.

For approval, 100% of the phase must be completed. In-person review by an ArtsWA representative is required to confirm the phase is completed to satisfaction. No portion of a fabrication phase may begin without explicit ArtsWA approval.

Schedule 2 – Digital Scan w/ 3D Printed Patterns Schedule 2 Summary Table - with review, approvals and recommended payment stages (x6)

Schedule 2 Process Description Table

Replication process

3d Digital Scan 3D digital scan by Form 3D Foundry, provided by ArtsWA or a 3D digital scan made by the foundry or their preferred vendor.

Requirements:

· Quality and size of the scan must be of a quality that accurately and precisely captures the surface detail, scale, design, and depth of surface texture of the original clay statue without distortion.

· Scan must be in a digital format which allows for 3D printing of patterns usable in a lost wax casting process.

· Scale of statue, including compensation for contraction during casting process, must not result in a completed cast metal statue greater than 9 feet tall, and a footprint wider than 41” and deeper than 41”.

To be considered 100% complete, a full resolution copy of the scan and a reduced resolution copy (80mb) must be provided to ArtsWA for review. Copies of the digital scan are unnecessary if using the scan made by Form 3D Foundry provided by ArtsWA.

0%

Requirements:

· Average pattern wall thickness must not be less than 1/8” thick, or greater than 1/4” thick.

· All patterns must be prepared with a non-porous surface for casting and approved for ceramic shell or plaster investment casting processes.

· Foundry must have a complete set of patterns in possession, onsite for review.

To be considered 100% complete, all patterns must have sprues, gates, and core-pins (if necessary) attached/installed to be considered ready to proceed to the next phase. ArtsWA will review and accept patterns based on the quality of their replication and readiness for the next stage. The stage will be complete when a full set of patterns for a statue have been completed and approved by ArtsWA.
