(vii) The launching girders are released from the segments.
(h) The launching girder is moved to the next span to repeat the process.
(i) A center part, footpaths and parapets are placed on the deck.
(j) The drain system on the bridge girders is completed.
(k) Weatherproof paint is laid over the entire elevated bridge.
10.2.2 Construction Schedule
The appendix 10.2-1 explains the outline and schedule for the Sirsi Circle-Town Hall Flyover (length 2.5 km) Construction Work at Mysore Road in Bangalore (hereinafter referred to as SCTH Flyover CW). The work will be performed by the incremental launching girder method, the same method as adopted in the BELRT project. We had an opportunity to observe the construction work.
As the construction method is the same, it is useful to analyze the plan and schedule of the SCTH Flyover CW for the purpose of discussing the construction schedule of the BELRT guideway.
(1) Outline of BELRT Guidway (Phase 1)
We will discuss Phase 1 of BELRT guidway based on the following conditions.
Route length: 25.9 km
Number of stations: 24
Position of guideway: Center of city street
Basic design: Elevated bridge with T-type single columns or portal rigid frame piers.
Construction system: Three shifts, 24 hours per day
Construction period: 1999-2001 (See Fig. 3-2-1 for details.)
Construction period: Three years
Year of opening: 2002
(2) Schedule of BELRT (Phase 1)
The Appendix 10.2-1 indicates that the schedule of cast-in-place pile installation, which is the basis of the construction work, is a bottleneck in the schedule.
Therefore, eleven sets of cast-in-place pile machines will be used to manufacture 3,072 piles (768 single columns x 4) of 1 m diameter and 20 m depth, 1,064 portal rigid frame type piles (133 portal rigid frame x 8 pieces) of 0.8 m diameter and 20
