		abstract={Pasar Rumput flats have 25 floors, with 1st ? 3rd floors functioning as
market areas and 4th ? 25th floors functioning as residential areas. As a high
building, Market grass flats must have a sturdy and strong structure, not just the
upper structure, but also the lower structure. But from the results of the land
investigation conducted by PT. TITIK UTAMA AGUNG Geotechnical
Engineering Consultant obtained soil type is silty clay, this type of soil is rather
difficult to do for planning the foundation because if it is still used the risk of
settlement will be very large. The foundation of the group bored pile with the
addition of pile cap can help support the building load, reduce the settlement
and make the loading location that works properly at the center point of the
foundation so as not to cause eccentricity which can cause additional loads on
the foundation.
Using the Reese and O'niell (1989) method and the Meyerhof (1976)
method, the capacity of a single drill pole carrying capacity with a diameter of
1m and a depth of 20m is 153.80 tons and 309.47 tons. The carrying capacity of
the pile group is the most efficient and works close to the maximum is in pile
cap number 4, the size of the pile group efficiency based on the Converse-
Lebarre method is 0.997 with the pile carrying capacity of the group for three
piles is 460.01 tons and 925.64 tons. The dimensions of the pile cap with
length, width, thickness based on the IS 456-2000 method are 3.3m, 3.3m,
2.9m. The settlement of group pile foundation analyzed by empirical and semiempirical
methods for single pile and group pile settlement using vesic method
(1977) were 0.00561 m and 0.01019 m respectively, declared safe against
collapse due to fulfilling the permissible decrease limit requirement of 0.1 m}
