Beam Splice Connection Methods for Narrow Bali Alleyways.

1. Modular segments start with access and design

Restricted access may require shorter delivery segments. The designer, fabricator, and transport provider determine their length after reviewing weight, vehicle dimensions, route, unloading space, and lifting equipment. Cutting a beam alone does not establish a workable erection method.

2. Splice locations follow structural analysis

There is no universal rule placing every splice at one-quarter or one-fifth of a span. Force distributions depend on supports, loads, and the frame system. Check axial force, shear, moment, load combinations, and temporary erection stability at the selected splice location.

3. Plates and bolts require calculation

Bolt quantity and size, flange/web plates, edge distances, holes, and weld details are not universal standard dimensions. The joint must provide the designed strength and stiffness. Do not equate Grade A325 with class 8.8 or use member thickness as the sole basis for plate thickness.

4. Trial assembly and erection sequence

Dimensional checks, component identification, and trial fitting can reveal discrepancies before dispatch. The erection plan still needs temporary stability, lifting points, installation sequence, and connection completion procedures. Bolt verification follows the joint type and project standard edition rather than a generic torque value.

5. Information owners should provide

Supply photographs of the route, gate dimensions, bends, cables, unloading areas, and nearby activities. Transport and construction teams assess feasibility against actual conditions. Keep revised drawings and a splice schedule so delivered segments can be traced to their references.
