5.2 Analisa Perhitungan Volume Pekerjaan
5.2.1. Penghitungan Volume Pekerjaan Tanah
a. Pembersihan Semak dan Pengupasan Tanah.
Luas = 10 m x Panjang jalan
= 10 m x 3500 m =
35.000 m²

b. Persiapan Badan Jalan m² .
Luas = Lebar lapis pondasi bawah x Panjang jalan
= 7,8 m x 3500 m = 27.300 m²
c. Galian Tanah Biasa m³
