IMPLEMENTATION OF BRIDGE MANAGEMENT SYSTEM ON INTERURBAN BRIDGE IN MALUKU PROVINCE
Abstract: Bridges as transport
infrastructures play a vital role in smoothing traffic flows. The success of a
bridge in playing its role and serving its function depends on its management.
The Directorate General of Highways of the Ministry of Public Work has used a
system to manage bridges known as the Bridge Management System (BMS). The
system allows a systematic plan and provides a uniform procedure for all bridge
operation activities on the national and provincial level. Data from
Implementation Agency of National Inter-Urban Roads of Area IX, Northern Maluku
in 2011 indicates that the total length of national roads in Maluku Province is
15,238.01 M, with a total of 562 bridges. In Ambon Island, especially, there
are 52 bridges totaling 1,176.25 m in length. The study was conducted at
several inter-urban bridges in Maluku Province of Ambon Island: Wai Batu Merah,
Wai Ruhu, Wai Lawa, Wai Yari and Wai Tua bridges. Assessment of bridge
structure conditions was conducted visually to determine the conditions of the
existing bridges comprehensively by referring to the Bridge Management System
(BMS) complemented with a computer-based Bridge Management Information System
(BMIS). Condition scores for the five bridges—Wai Batu Merah, Wai Ruhu, Wai
Lawa, Wai Yari, and Wai Tua, according to Bridge Management System, are 2, 1,
2, 1, and 2 respectively. The scores of the five bridges indicate that their
physical condition can be categorized as good or with minor defects. Based on
technical screening, the proposed treatment for Wai Batu Merah, Wai Ruhu, Wai
Lawa, dan Wai Tua bridges is the rehabilitation of their sub-elements. As for
the Wai Yari Bridge, the treatment will be maintained regularly. The defect
repair costs are IDR 149,138,238.00, IDR 81,048,000.00, IDR 174,579,106.10, IDR
79,233,324.01 and IDR 238,323,258.60 for Wai Batu, Wai Ruhu, Wai Lawa, Wai
Yari, and Wai Tua Bridges, respectively.
