5.2 Analisa Perhitungan Volume Pekerjaan
5.2.1. Penghitungan Volume Pekerjaan Tanah
1. Pembersihan Semak dan Pengupasan Tanah. Luas
= Lebar Badan Jalan x p. Jalan – p. Jembatan Total
= 11 m x 3087 m – 50 m
= 33.407 m² 2. Persiapan Badan Jalan m² .
Luas = Lebar lapis pondasi bawah x Panjang jalan
– p. Jembatan total
= 8,15 m x 3087 m – 50 m
= 25.109,05 m²
