Abstract

As Built Drawing merupakan gambar akhir dari objek yang sudah selesai pengerjaanya yang seharusnya tidak ada lagi perbedaan antara keduanya. Terdapat 2 parameter dalam melaksanakan penelitian ini yaitu bronjong sebagai objek amatan dan dokumen As Built Drawing sebagai pembanding. Dari kedua parameter tersebut terdapat variable guna mengerucutkan objek amatan. Variabel yang telah ditentukan berdasarkan studi literatur yaitu panjang tiap segmen, jumlah trap tiap segmen, tinggi trap dan lebar trap. Kemudian dari variable – variable tersebut dilakukan perbandingan secara head to head dari kedua parameter yang sudah ditentukan sebelumnya. Dari hasil amatan yang sudah diperoleh terdapat perbedaan pada parameter – parameter amatan sehingga menimbulkan selisih volume antara objek yang terbangun dengan As Built Drawing. Dari hasil tersebut dapat diberikan rekomendasi terkait dengan hasil akhir baik dari perlunya revisi dokumen As Built Drawing atau dari segi perlunya kembali review – review dokumen yang sudah diberikan oleh pihak kontraktor. Selain itu dapat memberikan masukan ke pihak pemberi kerja dalam hal masalah pelunasan pembayaran.

Abstract

Expansive clay soils have swelling and shrinkage properties and somehow reduce the mechanical properties required for soils to be used in civil engineering works. One method to improve the soil is by mechanical stabilization, namely mixing expansive clay soil with sand material. The sand material used in this research varied by 7.5%, 15%, and 22.5% of the total dry weight of expansive clay. The results shows that changes in mechanical properties were observed from the compaction test and California Bearing Ratio (CBR) both for soaked or unsoaked test. Based on these variations, in the compaction test, the addition of sand variations increases the maximum dry unit weight value and generally reduces the optimum water content value. The same results were also seen in the soaked and unsoaked CBR tests. In the swelling potential test, the addition of sand material succeeded in reducing the swelling value in expansive clay soils.
