2.1 MAINTENANCE ENGINEERING

2.1.1 Maintenance Principles
1. Maintenance engineering is both an art and a science. Availing of the state
of art and modern techniques in repair and rehabilitation will be required.
It is an essential part of bridge engineering which comprises of a host of Administrative Issues
other tasks and disciplines, including:
• Administration and related tasks such as bridge management, market-
ing, public relations, ethics, budgetary control, accounting, contract
law, land acquisition, and right-of-way jurisdiction
• Technical tasks such as analysis, diagnostic design, development of Section 1
procedures, training, mentoring, continuing education, construction
coordination, and construction supervision.
2. Among the many facets of engineering, maintenance requires a more
specialized approach than original design. Maintenance policy principles
are basically governed by design codes and guidelines. The following
guidelines need to be followed:
• In the case of replacement, the approach should be the three B’s—to
“Build Back Better.”

• Only identifi ed deficiencies of the superstructure need to be fi xed.
• Selective reconstruction depends upon performance of the diagnostic
design.
• The most common maintenance issues concern deck repairs.
• Maintenance is to a large extent based on the average daily traffi c vol-
ume and also on location in relation to hospitals, schools, or military
