Abstract
This study reports on developing an innovative approach for the parametric analysis of daylighting and visual comfort, through a sun Concrete pouring represents a major critical path activity that is often affected by design limitations, structural
considerations and on-site operational constraints. As such, meticulous planning is required to ensure that both
the aesthetic and structural integrity of joints between cast in-situ components is achieved. Failure to adequately
plan concrete pouring could lead to structural defects, construction rework or structural instability, all having
major financial implications. Given the inherent complexity of large-scale construction projects, the ‘manual
planning’ of concrete pouring is a challenging task and prone to human errors. Against this backdrop, this study
developed 4D Building Information Management (BIM) approach to facilitate automated concrete joint positioning
solution (as a proof of concept) for design professionals and contractors. The study first developed
structural model in Revit, then extracted spatial information regarding all construction joints and linked them to

مقاله: Sustainable Delivery of MegaProjects in Iran: Integrated Model of Contextual Factors
Abstract
This study develops an integrated model of the main contextual factors that affect sustainable delivery of megaprojects in Iran. The inputs to the model are based on a comprehensive literature review affecting the “triple bottom line” of sustainability, as measured in economic, environmental, and social costs. Innovation diffusion theory and extralogical laws of imitation inform the theoretical points of departure. The model inputs were customized for the context of Iran, and a structural equation model was developed, using data

مقاله: Integration Of Parametric Design into Modular Coordination : A Construction waste reduction workflow
این مقاله به دنبال کاهش میزان پرت مصالح مصرفی ساختمان های مدولار پیش ساخته می باشد، به گونه ای که با استفاده از گرس هاپر و گالاپاگوس این میزان به 2 درصد بر اساس استاندارد استفاده شده، کاهش پیدا کرده است.
Abstract
The construction industry is under pressure as to reduce the sizable quantities of construction waste generated during construction operations. Modular coordination (MC) and parametric design both have great potentials in reducing waste at the design stage. And anecdotal evidence suggests that great volumes of waste can be reduced through integration of parametric design into MC. The issue of proposing workflows in this context, however, is under-researched, and practical applications, if any, are at the rhetorical stage. To accomplish this, an integration attempt is made in this study to provide the details of a developed-and-experimented workflow for this purpose; a generative algorithm is developed through the Rhinoceros 3D-Grasshopper platform,

مقاله: How BIM increased project safety and improved profitability for building owners and investors
Abstract
Modern construction projects, such as tunnels, bridges and rail tracks, are more complex than ever, as architects,engineers and builders integrate state-of-the-art materials and technologies into designs to increase usability,maximise resource efficiencies and promote sustainability.The most advanced building planning and development technologies are therefore required to successfully navigate the decision-making process and to avoid costly and potentially harmful choices. To meet this need, the architecture, engineering and construction (AEC) industry is turning to digitisation, particularly in streamlining and optimising processes and

Daylighting and visual comfort of oriental sun responsive skins: A parametric analysis
Authors: Amir Tabadkani, Saeed Banihashemi, M.Reza Hosseini
Abstract
This study reports on developing an innovative approach for the parametric analysis of daylighting and visual comfort, through a sun responsive shading system. The objective is estimating the annual daylight metrics and indoor glare discomfort. To this end, a review of the literature was carried out on three key concepts: smart facades, visual comfort, and parametric design, in order to develop a dynamic pattern of an oriental system for enhancing the daylight and visual performance. Afterwards, two geometrical components (Rosette modules and louvers) were applied, using Grasshopper plug-in for Rhino and daylighting plug-in DIVA, to investigate the indoor daylight quality through different geometrical and physical properties. This resulted in
