Surabaya is the second largest city in Indonesia, which has many problems. Urban density is a major issue which has problems in it, starting from the population density up to the limitations of burial grounds that exist today. Design problem which arises is uniting the facility of funeral homes, crematoriums, and tombs in one area to reduce the mobilization on the road resulting in traffic density. Urban density has resulted in a couple of problems ranging from population density to scarcity of lands. Crematorium and vertical burial therefore become a crucial part of a city. While there has been less open green spaces, crematorium and vertical burial are expected not to reduce the open green spaces. Data scape as a design method is used to obtain design criteria for preliminary design. To obtain a form of structure, combination with the multiple addition geometry method is attempted. A design obtained by making vertical buriel footprint design that is able to provide sufficient absorption area by taking into account the percentage of urban open green space. To create a open green space and water absorption areas by lifting some mass of the building.

Dalam konstruksi pembangunan, Indonesia merupakan negara berkembang yang memiliki tingkat kefatalan kecelakaan kerja yang tinggi menurut International Labour Organization (ILO). Hal ini dikarenakan banyaknya pekerja dalam suatu proyek sehingga membutuhkan manajemen keselamatan dan kesehatan kerja (SMK3) yang baik. Namun, masih banyak perusahaan yang tidak menerapkan SMK3 bahkan termasuk proyek-proyek konstruksi yang berada di kota-kota besar. Hal ini didasari akan keinginan perusahaan dalam memperoleh profit yang tinggi sehingga mengabaikan keselamatan dan kesehatan pekerja. Dengan sistem manajemen K3 yang baik, setidaknya akan mencegah atau mengurangi risiko kecelakaan kerja yang ada. Program sistem manajemen K3 diawali dengan mencari potensi bahaya dari metode pelaksanaan yang digunakan agar dapat mengidentifikasi risiko yang ada, penilaian risiko dengan skala prioritas dan pengendalian bahaya yang harus dilaksanakan dimana pengendalian bahaya tersebut akan dilengkapi dengan program sosialisasi dan pelatihan K3. Dengan demikian, pekerja dapat bekerja dengan baik dan aman sehingga dapat mencapai target waktu dan target kualitas yang diinginkan dan direncanakan. Studi kasus yang diambil adalah struktur bangunan atas pada proyek Hotel Swiss-Belinn Juanda yang memiliki total 8 lantai dengan batasan pekerjaan bangunan atas, yaitu pekerjaan pembesian, bekisting, pengecoran. Dari sistem manajemen K3 yang direncanakan tersebut diperoleh biaya pengendalian risiko sejumlah Rp 310.266.500,00 yang dapat menjadi acuan dalam menekan angka kecelakaan.
