Fundamental tools for design, construction and project management, plans and specifications serve to bridge the gap between the customer’s needs and intentions, and the contractors who will carry out the work. Clear, precise plans and specifications help visualize and communicate the designer’s vision, guarantee construction consistency, and ensure compliance with current regulations and standards. In electromechanical engineering, there is typically one set of plans and specifications for each sub-discipline: heating-cooling, ventilation, regulation, plumbing, electricity, fire protection.
