Performance Work Statement SEADC Exhibit Lighting System

General Requirements

This is a non-personal services contract to replace selected LED lights and investigate the exhibit lighting system at the Forest Service Southeast Alaska Discovery Center (SEADC), Tongass National Forest, Alaska. The Government shall not exercise any supervision or control over the contract service providers performing the services herein. Such contract service providers shall be accountable solely to the contractor who, in turn, is responsible to the Government.

1.0 Background

The Southeast Alaska Discovery Center is a facility operated by the United States Forest Service (USFS). SEADC provides visitors with an educational experience through exhibits that highlight the ecology and history of Southeast Alaska and its connection to the Tongass National Forest.

The original exhibit lighting system was installed in 1994 during the building’s construction. In 2007, the exhibit track lighting system was removed and replaced with the current system. The existing lighting control system is manufactured by Strand Lighting, and the headend equipment consists of a Premiere 2020SE controller, a C21 switchboard (dimming rack), and a 100 Series 24-channel console. Strand Lighting was acquired by Vari-Lite and continues to provide products and services under that name. The lighting system includes approximately 1,040 linear feet of track and approximately 620 fixtures with a mix of halogen and LED lamps, although the system was originally designed for halogen lamps only.

SEADC staff have identified multiple issues related to system performance and safety. Major concerns include:

Difficulty sourcing replacement parts for the dimmer rack and processor.

The system failing to fully reboot after power outages.

Potential safety hazards within the track lighting system, including arcing and hotspots.

Lamps not meeting their manufacturer-specified lifespan.

Servicing challenges due to the control system manufacturer, Strand Lighting, no longer being in business.

Ongoing issues with the dimmer tower and associated controls located in the basement.

Persistent flickering in certain wall-mounted fixtures in the lobby.

Public and staff complaints that the existing lighting is excessively bright and generates too much heat.

The LED lamps have been found to be incompatible with the lighting system’s dimming rack, which is believed to be the root cause of many of the issues described above. Additionally, the lighting bases may have degraded over time, resulting in loose connections that could contribute to these issues and potentially create further problems. Therefore, the USFS requires replacement of all LED lamps with comparable halogen lamps.

The C21 dimming tower and Premiere 2020SE controller have been identified as likely points of failure within the SEADC lighting system. These components have experienced difficulties booting and rebooting following power outages, resulting in periods where the museum is left without lighting. Additionally, the specific models and their replacement components are no longer manufactured, making repair and maintenance increasingly difficult.

The repaired lighting system shall provide exhibit-quality illumination that maintains, at a minimum, the key functional features of the existing system. The objective is to implement a halogen-based lighting system that enhances visitor comfort, delivers softer ambient lighting, and addresses the safety concerns identified above.

While pursuing funding to plan, design, and implement a full replacement of the lighting system, the USFS is seeking to mitigate existing issues with the track lighting through targeted track lighting fixture replacements and by engaging a certified Vari-Lite technician to perform on-site diagnostics of the dimmer rack and controller.

2.0 Purpose

The purpose of this contract is to remediate deficiencies in the SEADC exhibit lighting system and ensure it operates safely, reliably, and in compliance with all applicable American National Standards Institute (ANSI) and Occupational Safety and Health Administration (OSHA) standards.
