Novotel Hotel BSD is a hotel that can be used a place to rest when having a
business trip, holiday, vacation, and many more. This project has 2 basements, 3 floor
of podium which includes ground floor, mezzanine, and upper ground, and 13 floor
of tower. The top of the building is at +70.32 m from the land surface. This makes
this project categorized as high-rise building construction. With there are 2
basements in this building, retaining wall is needed to resist the soil on entering the
basement.
Type of retaining wall used in this project is smooth wall which friction does
not occur on the surface of the wall. The design of the retaining wall is calculated
with lateral earth pressure and water pressure which act on the retaining wall. The
calculation of lateral earth pressure can be calculated by using the data of unit weight
of the soil, cohesion, and internal angle are obtained from the triaxial test and unit
weight test. The reinforcement design analysis is using D19-150 for vertical direction
and D13-150 for horizontal direction.
