If the installation will include remodeling of the sanctuary to accommodate the instrument, an architect should be consulted. A detailed accounting of cost and timetable for completion should also be included in the proposal. Nor is it fair to compare bids for tracker action with electric action or pipe organs with electronic instruments. Each individual builder will have a unique product, particularly in tonal quality, so keep in mind as you negotiate with various organ companies that cost figures alone do not tell the whole story. When the negotiation process is complete, a detailed contract that includes drawings, specifications, and financial arrangements should be drawn.
Most organ builders use a standard contract.
Your congregation's attorney should review the contract before it is signed. Some congregations wish to have the builder secure financial bonding to ensure completion of the project in the unlikely event that the contracted builder cannot complete the project. If you feel it is in your best interest, the bond should be a part of your negotiations with the builder. Frequent and open communication between everyone involved will ensure that the project proceeds smoothly. Purchasing a new organ is a big event in the life of a parish.
