Recently, infrastructure developments in Indonesia have been increasingly
massive, fast, and advancing. To support infrastructure development in Indonesia, civil
engineers who are well-equipped with knowledge are needed. Therefore, in supporting
the fulfillment of civil engineering needs, the University of Atma Jaya Yogyakarta
designed a Final Project in the form of infrastructure design, which in this case, the
designed The West Papua People’s Assembly Building in Manokwari, West Papua. This
building was used to support the government in making the decision in Manokwari related
to the constitution.
The design of The West Papua People’s Assembly Building is carried out by
calculating structural requirements, which include the upper structure (superstructure),
and lower structure (substructure), then proceeding with calculating the construction
management plan. Software like SAP2000, ETABS, and SPColumn is used in the
superstructure design. Utilizing ETABS software and Microsoft Excel, the substructure
was developed. Meanwhile, Microsoft Project is used to plan the construction
management planning. The superstructure's roof, beam, column, floor slab, and staircase
designs are all included. The substructure consists of interpretation of soil planning data,
soil bearing capacity analysis, liquefaction zone analysis, settlement analysis, and
footplate foundation planning. Last, Project Management includes Work Breakdown
Structure (WBS), Volume, Work Unit Price Analysis (AHSP), Bill of Quantities (BOQ),
Work Duration, Gantt Charts, Resource Sheet, Network Diagram and S-curve.
The design includes several aspects. The first aspect is the roof structure that uses
light steel. Then the dimensions of the columns in the building are calculated to meet the
required conditions. In the geotechnical aspect, the design starts with classifying the soil
site obtained from the given soil data. Then calculate the bearing capacity of the soil, after
that determine the type of foundation and the dimensions of the foundation needed. Based
on the series of calculations, the cost and duration of the work are obtained.
The structural design results obtained in this final project are steel profile
dimensions for truss, curtain rods, staircase dimensions, structural dimensions of plates,
beams, columns, shallow foundations or footplate foundations. The roof frame uses
double angles 50 x 50 x 5. The main beam dimensions are used 400 x 600, and the
secondary beams are used with dimensions 350 x 400. The columns used in the West
Papua People's Assembly Building use dimensions 600 x 600. The dimensions of the
floor plates used are the thickness 15 cm with two-way plate type. In the lower structure
footplate foundation is used with dimensions of 35 x 35 with a depth of 3.5 m. In project
management planning, it took 218 days with a total cost of Rp15,001,290,000.00.
