This article presents a GIS-aided visibility and dominance analysis used for a visual-impact assessment of a planned high-rise building located in a central area in Trondheim, Norway. The visibility analysis calculates fields of intervisibility between the high-rise building and locations in the urban landscape. Visual obstacles such as existing buildings and trees are included. The dominance analysis adds to the visibility analysis a measure of how visually dominant the high-rise building would be. The dominance measure is based on the distance to the building and how much of the building would be visible from any observation point. The result is an assessment of visibility and dominance throughout the entire study area as opposed to using photomontages for assessing visibility and dominance from single standpoints.

Technical Measures

Mass concrete is widely being used in the construction field, especially for the foundation of super high-rise building. In the initial stage of pouring completion of mass concrete, lots of heat generated from the cement hydration will lead to a high temperature inside of concrete. When the temperature difference between the inner and outer of concrete exceeds the limited value, thermal stress will be greater than the tensile strength of concrete, which may cause hazardous penetrating cracks of the structure. To ensure the safety and durability of concrete structure, necessary measures should be taken to control the temperature rise and construction quality of concrete. Taking a super high-rise building project as an example, this paper introduces several effective solutions to resolve above problems. The technical measures such as enhancing the concrete quality, controlling temperature rise, strengthening temperature monitoring would be detailed illustrated. Meanwhile, valuable suggestions achieved from this practical project are proposed in order to guide the structural design and on-site construction of similar projects.

Failure Factors

A poorly coordinated performance among stakeholders in the finishing phase can impair the performance of a high-rise building project. Therefore, it is necessary to analyze construction failure factors (CFFs) to stakeholder coordinating performance (SCP) in the finishing phase of high-rise building projects and to uncover their underlying relationships. CFFs to SCP in construction projects, especially in the finishing phase of high-rise building projects, have not yet been discovered. The study identified 30 CFFs to the SCP and ranked them according to the perspective of the stakeholders, including owners/consultants and contractors/subcontractors. Additionally, four factors of the CFFs, namely, traditional adversarial relationship, poor project planning and organization, incompetent parties, and delays of parties toward construction works were extracted by the factor analysis method. This study fills the gap in knowledge related to the coordination performance in construction projects. The findings could help stakeholders to enhance their coordinating performance in high-rise building projects.

As the population growth and land resources declining, high-rise building project is increasingly common in the construction work. Through in-depth thinking and active exploration, specific attention to matters of deep foundation pit and pile foundation construction technique, which is the key construction techniques in the high-rise building project, was summarized in this article. It suggests to make a careful and detailed geological survey, and then choose the right design program and develop a reliable construction plans. This scheme was proved to be a useful reference and guidance for the development of high-rise building construction technology.

Building Project

In a high-rise building project that involves many repetitive construction processes, the effective control of such repetitive construction processes is a key factor in the success of the project. Unlike the existing scheduling methods for repetitive construction processes, a scheduling model that considers (i) the flexible job logic of the multiple work tasks that comprise a construction process and (ii) the productivity of the construction equipment and labor was developed in this paper. Various theories and algorithms such as the linking dummy, the linear scheduling method, and the production rate, were implemented in the development of the model. A scheduling model was then proposed based on such theories and algorithms and on a mathematical formula. The proposed model was verified by applying it to core wall construction, a key repetitive process in a high-rise building project. Verification showed that the developed model exhibited over 90% reliability. It is expected that the proposed model will allow effective scheduling for repetitive construction processes with flexible job logic.

Building Project

Time delays in construction project will be very detrimental for both the provider and user of construction service because it can cause a conflict which leads to time demand and additional cost. The timeliness in construction of basement is one of the important aspect to gain a success at construction project, remembering basement is an early phase of development at high-rise building project. The purpose of this study is to analyze the factors that can cause time delay in high-rise building semi top-down basement work. The research method used in this study is quantitative and descriptive approach with questionnaire distribution to some high-rise building projects with semi top-down basement. With the help of SPSS software, next step is to analyzing the data in the form of a validity test, reliability test, normality test, and Relative Importance Index (RII) test. The result of this study shows 5 factors that cause the most influence the delay of semi top-down basement work based on the importance ranking is variation and changes of order by owner, low productivity level of labors, leak on the diaphragm wall, repeated changes rebar layout due to space that too narrow, and material delivery delays. ABSTRAKKeterlambatan waktu pada pelaksanaan proyek akan sangat merugikan para pelaku jasa konstruksi karena dapat menyebabkan konflik yang berujung terjadinya tuntutan waktu dan biaya tambahan. Ketepatan waktu pada pekerjaan basement merupakan salah satu aspek penting dalam kelancaran suatu proyek konstruksi, mengingat basement merupakan salah satu pembangunan tahap awal pada proyek gedung bertingkat. Penelitian ini bertujuan untuk menganalisa faktor-faktor yang dapat mempengaruhi keterlambatan waktu pada pekerjaan basement semi-top down. Metode penelitian yang digunakan pada studi ini adalah pendekatan secara deskriptif kuantitatif dengan penyebaran kuesioner kepada beberapa proyek gedung bertingkat dengan basement semi top-down. Selanjutnya, dilakukan pengolahan data dengan bantuan software SPSS berupa uji validitas, uji reliabilitas, uji normalitas, dan Relative Importance Index (RII). Hasil penelitian menunjukkan, terdapat 5 faktor yang paling mempengaruhi keterlambatan pekerjaan basement semi top-down menurut tingkat pengaruhnya yaitu perubahan perintah kerja dan variasi dari owner, produktivitas pekerja lapangan yang rendah, terjadi kebocoran pada Dinding Penahan Tanah (DPT), pengaturan tata letak penyimpanan tulangan yang berulang-ulang akibat lahan yang terlalu sempit, dan pengiriman material yang terlambat.
