When sizes or measurements are part of your specifications for an item, indicate maximums or minimums or approximates. If the item must fit into a given space, indicate the available space. When weight is an important factor, indicate the acceptable range or minimum or maximum acceptable weight. Delivery, warranty, or training requirements are to be clearly defined. When compatibility with an existing piece of equipment is a factor, describe the equipment, connectors, interfaces, and brand and model of the existing equipment.
Specifications are to clearly state packaging requirements, size, types of finishes, etc.
Verify that models are still available before submitting specifications. Valuable time is often lost by requesting models that have been discontinued. When installation is required, provide details on what is expected of the contractor. If a site visit is required, indicate a contact name and telephone number. When maintenance is requested, define the extent of service, parts, labor, travel, service hours required, number of preventative maintenance inspections, and any other inclusions or exclusions.
