When artistic hardware of a high grade is to be used, and especially for large buildings, it is best not to include the hardware trimmings in the general contract, but to buy it direct from the manufacturers or dealers, selecting from samples. In this way the owner gets just what he wishes and with the least bother. In such case the carpenter's specifications should provide for putting on the hardware.
When it is not practicable to separate the hardware trimmings from the general contract, one of two methods may be used for specifying it.
The first, and one that is largely followed by architects, 5s to specify that the builder shall allow a certain amount of money for the door and window trimmings, exclusive of the cost of putting on, the architect or owner to have the privilege of selecting and ordering the hardware wherever he may choose, and the bill to be paid by the builder, to the amount of the allowance. This enables the architect to put off selecting the hardware until the building is nearly ready for it, and gives the owner a chance to select the style of hardware he prefers. The allowance may be so much per door and window or in a lump sum, but the latter will usually prove the more satisfactory. The only objection to this method is that the architect, to be on the safe side, generally makes the allowance a little more than the hardware which he would specify would actually cost the builder, so that the owner usually pays a little more for his hardware by this method than he would by the other. Then also the trouble of selecting the hardware is often more than that of describing the goods to be used.
The amount of the allowance will of course depend upon the class of goods to be used, and the number of the doors and windows. In making up his estimate, the architect may be guided by the prices given in Section 251, for plain goods; for ornamental hardware he should get prices from a local dealer.
A form of specification by this method will be found in Chapter VIII (Architectural Terra Cotta).
The second method of specifying the hardware, and in the opinion of the author the best method, is to describe exactly what is wanted, and in the case of special styles or patterns the number of the piece in the manufacturer's catalogue, with the material and finish properly indicated, should be given. Locks should always be specified by name and number, as most manufacturers make several grades. This requires a little more knowledge of the subject than the other method, but except where elaborate trimmings are to be used it is generally the most satisfactory, and where the hardware can be specified in sets it is not as much trouble as to go to a store and pick it out. By this method the architect does not have to deal directly with the matter of cost, but has only to write his specifications so as to include all the hardware required and describe it clearly, and then see as the building progresses that it is furnished according to the specifications. A typical specification of this kind is also given in Chapter VIII (Architectural Terra Cotta).
