The discontinuities play an important role in both the design and development stages of many geotechnical engineering projects. Therefore, semi-automatic detection of discontinuities based on remote sensing will save a considerable amount of time and cost. Accuracy of the semi-automatically detected discontinuities is also as important as the detection process, since the results directly reflect the uncertainty in the geotechnical problem. The current paper presents an accuracy assessment methodology for semi-automatically detected discontinuities from remotely sensed images. Semi-automatic lineament analysis is performed by using high-resolution satellite imagery for identification of rock discontinuities at the Andesite quarry area in Golbas1 Ankara, Turkey. A highresolution data IKONOS Precision Plus with 1m resolution orthorectified image has been used in the present study. The accuracy assessment methodology is developed based on a comparison of manually extracted lineaments using directional filtering and semi-automatically detected lineaments with LINE module of PCI Geomatica 8.2 and manual intervention. The proposed accuracy assessment methodology considers the accuracy based on location and length of the lineaments. In this respect, it has two dimensions. For the algorithm of the developed methodology, a software called LINECOMP, is coded in Java environment. The LINECOMP is composed of three modules. These are: LINE ADDRESS for identification of pixel addresses of lineaments; which is used for locational accuracy assessment; LINE COMPARE for comparing two lineament maps with respect to lineament pixels, which is used for length-based accuracy; and LINE CLASSIFICATION for classifying the assessed accuracy with respect to the amount of location and length matching. The performance of the proposed accuracy assessment method is also verified by the field studies carried out in the study area.

The discontinuities play an important role both in design and development stages of many geotechnical engineering projects. Because of that considerable time and capital should be spent to determine discontinuity sets by conventional methods. This thesis present the results of the studies associated with the application of the Remote Sensing (RS) and the development of a methodology in accurately and automatically detecting the discontinuity sets. For detection of the discontinuities, automatic lineament an...

Sarıçiçek, Yılmaz Emre; Pekcan, Onur; Department of Civil Engineering (2016)
The development of innovative solutions to improve the engineering characteristics of sands becomes an emerging field of Geotechnical Engineering, as the environmental aspects, the economic feasibility and application practicability are concerned. In this scope, many improvement methods have been proposed to satisfy sustainability constraints, to reduce the overall the cost of construction and to be applied safely in the field. Among those, the use of biological means as derived from the nature gets popular...
A Taxonomy for causes of changes in construction
Rahmani Mirshekarlou, Babak; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Department of Civil Engineering (2012)
Change is an inevitable and inherent factor of each construction project which is a result of the nature of industry and the uniqueness of projects. Risky and unstable environment of construction industry usually triggers the potential of occurring changes during a project life cycle. Effective management of changes usually leads to increasing the project success. Change prediction and evaluation is the major step of change management process which enables the project management team to have a clear perspec...
An Integrated regression-bootstrap sampling scheduling method for probabilistic duration range estimation of construction projects
Barış, Özgür; Sönmez, Rifat; Department of Civil Engineering (2019)
The estimation of project duration is important in construction projects, since it directly affects the costs and the success of the projects. Schedule risks can be determined along with the duration estimations in order to assess the possibility of delay penalties and additional costs. Therefore, the accuracy of the estimation of project duration range is very crucial in construction industry to assess the schedule risks. This thesis presents an integrated approach of non-parametric bootstrap sampling meth...
A knowledge representation tool for architectural spaces : a study on surgery unitsh
Us, Mehta; Tanyer, Ali Murat; Department of Building Science in Architecture (2019)
The nature of construction projects is very iterative and there are various people involved from different disciplines and organizations in the process. Design stage is unique, complex and require combination and expertise of different people. The capture and reuse of design experience is considered as an efficient way to promote a better design process and efficient building solutions. The smallest part in a building is the space. It is a long-term asset of a building; therefore, a space knowledge manageme...
