5.2 Analisa Perhitungan Volume Pekerjaan
5.2.1. Penghitungan Volume Pekerjaan Tanah
1. Pembersihan Semak dan Pengupasan Tanah.
Luas =10 m xPanjang jalan – Bentang Jembatan – Lebar persimpangan
= 10 m x 3000 – 600 – 12 =
23.880 m²
2. Persiapan Badan Jalan m² .
Luas = Lebar lapis pondasi bawah x Panjang jalan – Bentang Jembatan
– Lebar persimpangan = 7,77 m x 3000 – 600 – 12
= 18.554,47 m²
