Systems construction techniques have recently been used in the widening and replacement of numerous substandard or deteriorated short-span bridges in Virginia. The techniques involve the mass production of precast concrete components to one or more standard dimensions. Standard designs have been used for precast slab superstructures in the 3.1-9.1 m (10-30 ft.) span range, and for precast, prestressed single T-beams in the 9.1-20.1 m (30-66 ft.) span range. A modular precast parapet has been developed to accommodate all span lengths. Other modular concrete components that have been used include the channel beam, box beam, I-beam, and permanent bridge deck form. Evaluations have shown that the use of these mass produced components can minimize bridge costs; the same forms can be used many times and costly on-site forming and form removal are eliminated. Also investigations have shown that the use of precast components enables a reduction in on-site construction time that provides motor vehicle fuel savings for construction personnel and the traveling public. The experience in Virginia suggests that systems construction is an economical and operationally efficient method for widening or replacing short-span bridges. /Author/
