The effectiveness in site layout and construction planning for extremely large-scale and complicated construction projects not only affects productivity and cost, it also controls whether a project can be handled and completed in a practical, safe, orderly, efficient and engineering feasible manner. Projects qualified to be extremely large and complicated can be in a variety of forms. Take for ...

UNLABELLED Graph layout is extensively used in the field of mathematics and computer science, however these ideas and methods have not been extended in a general fashion to the construction of graphs for biological data. To this end, we have implemented a version of the Fruchterman Rheingold graph layout algorithm, extensively modified for the purpose of similarity analysis in biology. This alg...

As a result of automated construction methods, which many construction companies have worked on these days. Consequently, the following construction planning systems are needed .1) the best framework partition plan, 2) the best layout plan of the hardware and the best usage plan of workers at the construction site, 3) the output of the stage of execution works, in a short period of time. This s...

Virtual prototyping (VP) technology has been regarded as a cost-effective way of envisaging real circumstances that enhance effective communication of designs and ideas, without manufacturing physical samples. In the construction field, although a large number of digital technologies have been developed to visualize the innovative architectural design, few VP systems have been developed to faci...

The sewer layout in flat areas significantly influences the construction and operational costs as well as reliability of the network performance. To find an optimum design of sewer networks for flat areas, this study presents a multi-objective optimization problem with the objective functions of 1- the cost and 2- the reliability. The reliability criterion is defined as the effect of a clogging...

We propose a new class of artiicial neural networks for regression tasks and its construction algorithm. These networks have two diierent but isomorphic layouts. The tree-structured layout is used and built up during the construction phase and it can be used for accelerated serial evaluation of the network. The three-layer layout can be derived from the tree-structured layout by a simple mappin...

The online observation of a construction site and processes bears significant advantage to all business sector. BIM is the combination of a 3D model of the project and a project-planning program which improves the project planning model by up to 6D (Adding Time, Cost and Material Information dimensions to the model). RFID technology is an appropriate information synchronization tool between the...

Chalk lines are used to print layouts in construction sites indicate the location of attaching or cutting objects; printing depends on skills workers and is suitable for small-scale work. Moreover, this type work requires a precise measurement process, which time-consuming, avoid errors. Thus, discrepancies between blueprints site can occur if plans management not uniformly aligned. To improve ...

Building Information Modelling (BIM) represents a long-term investment that could allow reduction of time and cost control by optimising design and construction processes. It also ensures greater effectiveness of control systems. The paper is focused on a public procurement case study regarding the BIM-based validation and construction optimisation of an actual residential building designed in ...
