1. Background
Koh Tao is a significant tourism destination facing critical land resource constraints and a continuous increase in waste volume. To support community-led waste management and promote a Circular Economy, the project has provided support for reusable plastic containers (such as cups, plates, and bowls) as a key component of the campaign to reduce single-use plastics. These reusable alternatives are intended to be fully utilized during various events and festivals on the island to promote sustainable practices, raise environmental awareness, and tangibly decrease single-use plastic waste generation.
To facilitate the efficient cleaning and sanitization of these reusable containers, as well as glass bottles and other circular materials, the project requires the procurement of a high-efficiency commercial dishwasher to be installed at the Community Waste Management Center on Koh Tao. This equipment will ensure that resources are safely and rapidly returned to the system, leading to a measurable reduction in waste sent to landfills and enhancing the operational agility of local community initiatives.
2. Objectives
· To procure a high-efficiency, durable commercial dishwasher suitable for operation within an island environment.
· To reduce cleaning time, lower operational costs, and minimize water and energy consumption compared to manual washing.
· To elevate hygiene standards in the management of circular materials and reusable packaging.
3. Scope of Work
The successful bidder shall be responsible for the supply, delivery, and installation of the commercial dishwasher at the designated site, covering the following:
· Safe transportation and delivery of the equipment to the installation site on Koh Tao.
· Site survey and technical advisory on utility preparation (water inlet, drainage, and electrical systems) prior to installation.
· Professional installation and connection to the provided utility points.
· System testing (Commissioning) to verify operational performance and safety.
· Comprehensive training on operation and basic maintenance for the designated operators.
