Abstract

ABSTRACT: In construction, rework is unavoidable. Rework usually occurs due to mistake from workmanship cause by change, error and omission. Additional cost accruing from of rework on a construction project in Surabaya is around 5.7% from the total cost of project.In this research, questionnaires were distributed to contractors in Surabaya. Questionnaires were composed based on the construction phases, the sources and the causes of rework in order to design a model of rework on construction project. With the establishment of the sources and causes model of rework project managers can anticipate the occurrence of rework in accordance with the project construction phase.The research findings show that construction project in general, rework happens frequently in the phase of finishing activity in the construction phase, the sources of rework that must be considered for finishing activity is due to change order and followed by error that is caused by lack of leadership and communication. The highest intensity of the main indicators of the causes is inadequatecy of supervision and job planning.

Abstract

ABSTRACT: Besides visual aspect, room acoustic performance is also an important factor in determining multipurpose hall performance. Room acoustic performance can be achieved if some room acoustic objective parameters are taken into account, such as background noise level, reverberation time, and sound coverage. In order to meet these parameters, it can be done by using materials with appropriate coefficient absorbstion on floor, wall, ceiling and room geometry. Room acoustic objective parameters should be considered in design phase for optimum benefit. Room acoustic simulation on the design of multipurpose hall P1 and P2 Petra Christian University will be done by computer simulation.

Abstract

Apartment’s project cost planning involves a Quantity Surveyor to determine the target cost (budget) for the owner. Target cost must included all elements of the existing building. This study aims to determine the format and price range of each building element in the elemental cost analysis for apartment’s project cost planning.The data were obtained by looking at historical data of the middle class  apartment’s projects Bill of Quantity in area of Surabaya, Solo and Semarang with reference to the format NPWC List of Elements, Australia.The results of the data analysis showed that the format of building elements that can be used in elemental cost analysis consists of 11 major elements are Preliminaries, Sub-structure, Super-structure, Finishes, Fittings, Services, Site Works, External Services, Waterproofing, Grills & Iron, and Pool. While the price range of elements in the elemental cost analysis showed that the apartment’s project which has a basement, the price difference is 20-30% larger than projects that do not have a basement. For the project which has storey height ≥ 3m, the price difference is 3.5-20% larger than projects which has storey height < 3m. For projects which has a basement & storey height ≥ 3m, the price difference is 30% larger than the project which has a basement & storey height <3m. Keyword : cost planning, target cost, apartment’s project, building elements, elemental cost analysis

Abstract

Green building concept has been widely developed globally as well as in Indonesia. Green Building Council Indonesia (GBCI) is the institution that organizes the green building certification in Indonesia. The view from construction parties is needed to understand the level of interest and level of implementation of green building parameters and the impact of green building parameters on project life cycle time. This research carried out by distributing questionnaires to construction parties in Jakarta and Surabaya. Descriptive analysis and Structural Equation Modelling is used to understand the respondent views of the green building parameters and the impact of green building parameters on project life cycle time.The results showed that the level of interest of green building parameters is high. The comparison between level of importance and level of implementation shows that the implementation rate is lower than the importance rate. Water conservation is a significant aspect affecting the project life cycle time specifically the design stage, while the other aspects haven’t been significantly affecting project life cycle time.

Abstract

Ada sebuah metode penjadwalan baru yang dikembangkan tahun 2007 oleh Murray B. Woolf, yaitu Performance Intensity. Metode ini mempunyai dua variabel utama yaitu duration days dan time consumption. Penelitian ini bertujuan untuk melakukan monitoring dan analisa dengan menggunakan metode Performance Intensity dan CPM dengan dan mengetahui perbandingan analisa tanggal akhir sebuah proyek menggunakan metode Performance Intensity dengan metode penjadwalan CPM yang lebih dulu digunakan. Penelitian ini mempunyai batasan yaitu pekerjaan struktur, dinding dan tangga. Untuk melakukan penelitian ini diperlukan jadwal rencana sebagai acuan. Selain itu diperlukan data start date, finish date, persentase selesai tiap aktivitas yang didapat dari hasil monitoring setiap hari dan dilakukan analisa perbandingan mingguan dengan jadwal rencana.          Jadwal rencana awal proyek selama 189 hari. Penelitian dilakukan selama 10 minggu dimulai dari tanggal 15 September 2014. Hasil dari penelitian adalah terdapat perbedaan analisa tanggal akhir antara metode Performance Intensity dengan metode CPM. Analisa tanggal akhir Performance Intensity mempunyai range antara 123-185 hari, sedangkan analisa metode CPM mempunyai range 175-199 hari. Perbedaaan range analisa prediksi tanggal berakhirnya proyek disebabkan metode Performance Intensity menggunakan laju pekerjaan kumulatif rata-rata sebagai tolak ukurnya yang selalu berubah-ubah tiap periode.

Abstract

Dalam lingkungan yang kompetitif seperti sekarang ini, pengetahuan tentang kebutuhan konsumen sangat penting bagi suatu perusahaan agar dapat bertahan. Quality Function Deployment (QFD) merupakan metode yang cocok untuk menganalisis kebutuhan konsumen karena QFD dapat menterjemahkan kebutuhan konsumen ke dalam suatu deskripsi teknis dan memastikan setiap hal yang penting dapat diprioritaskan dalam rekomendasi perancangan perumahan tersebut. Belum ada yang melakukan analisis kebutuhan konsumen dan menterjemahkannya kedalam suatu deskripsi teknis pada perumahan dengan luas bangunan 36-70 m2  di Surabaya, sehingga hal ini mendorong peneliti untuk menerapkan metode QFD pada perumahan dengan luas bangunan 36-70 m2 di Surabaya. Pada penelitian ini didapatkan 10 hal yang dapat dilakuan untuk perbaikan perumahan A di Surabaya timur yaitu CCTV, one gate system, kebijakan rumah hanya untuk hunian, tulangan sesuai SNI, sistem keamanan terpadu (patroli setiap 2 jam), lampu jalan setiap 30-40 m, perbaikan kekuatan tanah, saluran drainase tertutup, pengecekan bak kontrol drainase setiap 1 bulan, komplain ditanggapi maksimum 1-2 minggu.
