The organ enclosure again can be taped and sealed with visqueen to prevent dust ingress. Allow for Makin Organs Ltd carrying out a service and clean of the organ upon completion of the works. The organ is to remain playable throughout the contract period for all services, weddings, funerals, etc. The successful Contractor is to submit a Method Statement along with a programme of the works before any works start on site. The works will be subject to the Health & Safety CDM Regulations and a CDM Co-ordinator will be appointed to oversee all Health & Safety issues. The Contractor is to respect the nature of the building and is to suspend all works during any funeral and wedding services and is to ensure that the church is in a tidy condition for those events. The Contractor is to allow for this in his tender.
