Butterfly House Duty/Standby Heater Project

The Horniman wishes to appoint a suitably qualified contractor to carry out the replacement of the existing Powermatic gas fired heater in the Butterfly House, with a more robust heating system that incorporates a BMS connection for monitoring and a backup electrical heater battery in case of failure.

The Butterflies in the house are very susceptible to cold weather and the existing heater has no back-up within it, and is subject to faults.

The newly designed system will provide better air circulation in the space along with a back-up heater in case of mechanical failure.

The works also include structural adjustments to the glasshouse frame to incorporate the new air distribution ducts.

Some local plumbing work is included to remove an existing boosted water set up.

And install a new gas fired backup power generator for the Butterfly House.

The Butterfly House is a sensitive space full of living creatures and plants, it is governed by the Horniman museums zoo licence, so all works within the butterfly house must be done in accordance with the health and wellbeing of the living collection in mind.

Additionally the project will include for the strip out of existing ultrasonic humidifier in the music and temporary exhibition gallery AHU's, these are located within the main museum.

The contractor will be asked to install a new humidification system into the AHU's.

The effective management of health and safety risks and programme is considered key for the successful delivery of these works.

All works must be completed before the 31st March 2023 for funding reasons.
