The effective execution of architectural concrete starts with a constructable design from the architect's boards. Yet for the designer to make the best use of concrete both architecturally and economically, he must have the assurance that he can expect good results in its construction. Although many precasting facilities in this country are turning out high quality work, on-site construction of work of equal quality has been achieved less frequently. Rigid control at the job site usually has been harder to achieve than in the precast plant largely because adequate information on site-cast work has not been broadly available. The concrete constructor has profited by keeping all prices for materials, equipment, labor and techniques as low as possible. In the past most have been alarmed at some of the expenses related to architectural concrete work. Yet structural concrete and architectural concrete prices cannot be compared. The proper comparison is between the cost of architectural concrete and the cost of structural concrete plus that of later architectural treatment such as cladding with brick or other materials. The use of architectural concrete is becoming a necessary part of allowing commercial concrete structures to be competitive. If the structural concrete cannot be expressed architecturally with predictably good result, architects and owners will frequently find that the alternative is not clad concrete but a steel frame.
