Most companies do designs at no charge because the cost of the design is built into the total package that includes design, lighting units, and installation. If you are looking for a design to put out for bid or want to “do it yourself”, then the answer is yes. The cost for the design should include a set of drawings, electrical notes and have fixture types and the manufacture specification. Normally there is an hourly rate for design and a rate for producing these plans. The designer should be available to assist the installer and also do a night time walk thru.
