Savannah City Hall

Historic Lighting Restoration

Savannah City Hall

Job Site Savannah, GA

Project Description

Property History

Savannah City Hall is the seat of government for the city of Savannah, Georgia, United States. Designed by architect Hyman Witcover, the building was built between 1904 and 1905 and opened the following year. It is a contributing property to the Savannah Historic District. The building officially opened on January 2, 1906. In 1987, the dome was covered in gold leaf. In 2014, the Georgia Historical Society, working with the mayor and aldermen, erected a Georgia historical marker at the city hall.

Project Scope

Grand Light was commissioned to restore a variety of historic lighting fixtures from Savannah City Hall. This included a total of 42 ceiling lights, 34 wall sconces, and 6 lamp fixtures. First, Grand Light went on site to disassemble, remove, and transport each fixture back to the factory using our specialized moving trucks. Each fixture was disassembled, cleaned, and polished with a protective top coating to preserve the existing antique finishes.

Missing or damaged mechanical and decorative components were replaced with replicated parts to conserve the authentic design. For this part of the job Grand Light utilized lost-wax casting. Detailed wax replicas of the parts were created, encased in a ceramic shell, and melted out to create a precise mold. The molds were then filled with molten metal to produce highly detailed replications of the missing components.

Any intact glass globe diffusers were able to be restored through hand cleaning, while any damaged or missing units were refabricated with new similar-in-kind globes. To complete the restoration, each fixture had their electrical components replaced and rewired with UL listed products for modern safety standards and functionality.

Services Performed

On-Site Disassembly, Assembly, & Testing

Our restoration artisans are trained to safely remove and disassemble fixtures and components, labeling and photographing fixture components in sequence of its removal and as a section. Work areas are left in the same condition it was found prior to leaving the site.

For documentation our technicians inspect and note any electrical deficiencies on every lighting fixture prior to any electrical component replacement and rewiring, to ensure the fixtures can be wired in accordance with UL listed products, UL standard 1598 and hi-pot tested, with UL label (LED retrofit kits utilize manufacturers listing).

On-Site Packing, Crating, & Transportation

Grand Light frequently transports lighting fixtures using our own box trucks, flatbeds, and custom-built trailers that are designed specifically for safe transport. Our team packs all components with custom-built crates catered to each fixture in our factory. Each crate is packed and properly labeled with all necessary information per fixture type, including loose components, damages/deficiencies, and proper component placement/alignment.

Lighting Design & Engineering

Our process begins with reviewing existing documentation including sketches, architectural drawings, historical photographs, and an on-site inspection to gather the full scope of the project requirements. From there, Grand Light will develop a detailed proposal. As required Grand Light conducts research to assure the historical accuracy of all historic projects.

The creation of Custom Drawings, Modeling, Simulation, and Rendering is an important part of the process when it comes to the production of custom lighting. Whether it be a replication or modification of an existing lighting fixture, the client’s design, or a creation by Grand Light’s engineering team, our designs will serve as the blue print for our production process.

Our designs and subsequent mock-ups address the smallest of detail, allowing our clients to fully visualize the fixture before it goes into production, which reduces the possibility of error, and allows Grand Light to fulfill its commitment of delivering high quality lighting fixtures on schedule.

Cleaning Systems

Grand Light specializes in commercial luminaire cleaning services, including the utilization of state-of-the-art Ultrasonic, Micro-Abrasive, and Hydrosonic Molecular Impact System (HSMI) Cleaning Technologies. Using our engineered cleaning systems, our artisans are able to eliminate decades of accumulated debris from any lighting fixture or surface.

Grand Light’s Industrial Ultrasonic Cleaning Tanks provide high-frequency sound waves transmitted through liquid to scrub clean the surface of immersed parts. The high-frequency sound waves, typically 40 kHz, agitate the liquid solution of water or solvent, and cause the cavitation of solution molecules.

Our Micro-Abrasive process utilizes fine abrasive media to generate an accurate, precise, and controllable abrasive jet to target and remove material (on the micron level). Our system is so precise it can remove ink from a business card without damaging the card’s surface.

HSMI is Grand Light’s unique, proprietary system includes powerful continuous super high steam production up to 369 degrees Fahrenheit with an integrated wet vacuum system insuring residual moisture and debris extraction. Purified dry vapor steam and integrated vacuum system guarantees spot free crystals and fixture frames.

Finish Application & Top Coatings

As a part of the restoration process, our artisans explore the intricate details of preserving the historical integrity of lighting fixtures including color matching and sheen of the original finish. Custom lighting finishes are available in custom painted colors, sheen, and textures as well as custom patina colors on bronze, copper, and brass components.

Our artisans can match any color or finish utilizing a variety of processes involving Powder Coat, Spray, Hot or Cold Patina Custom Recipes and Color Blending an existing finish.

Grand Light exercises meticulous techniques that are unparalleled in the application of Protective Top Coatings including binders, rust, and UV resistant protective metal oils, waxes, and lacquers with various customized sheens and tints.

Replication Casting

Our metalsmiths can fabricate a variety of materials by hand forging or producing components utilizing the Lost-Wax and Sand Casting Processes. Our custom cast metal fixtures offer complex design, quality, and durability.

The Lost-Wax process consists of utilizing existing components replicate intricate detailing, shape, and size through the combination of custom molds, wax patterns, and ceramic shells. This process offers great precision and can replicate components ranging from tiny parts and entire frame castings.

Sand casting is a manufacturing process in which molten metal is poured into a sand mold containing a hollow cavity of the desired shape. After a period of time, the casting cools and solidifies. The sand is then broken away and shaken out.

NRTL Testing & Listing

Utilizing only UL listed products, Grand Light’s OSHA NRTL Certified Manufacturer’s Testing and Listing Laboratory strives to ensure only the highest quality of standards go into finalizing each lighting fixture; from the rewiring of luminaires, to the installation of modern lamp technology, and the custom conversion of gas powered fixtures to electric.

Grand Light’s technicians inspect and document any electrical deficiencies on every lighting fixture prior to any electrical component replacement and rewiring. We also offer comprehensive retrofit kits for upgrading existing historic luminaire to take full advantage of modern induction lamping technology. Grand Light’s practice is to perform multiple UL tests on all electrical components and systems to ensure compliance with UL Standards for luminaires.
