Hijazi Architectural Object Library (Haol)

Abstract

ABSTRACT:As with many historical buildings around the world, building façades are of special interest; moreover, the details of such windows, stonework, and ornaments give each historic building its individual character. Each object of these buildings must be classified in an architectural object library. Recently, a number of researches have been focusing on this topic in Europe and Canada. From this standpoint, the Hijazi Architectural Objects Library (HAOL) has reproduced Hijazi elements as 3D computer models, which are modelled using a Revit Family (RFA). The HAOL will be dependent on the image survey and point cloud data. The Hijazi Object such as Roshan and Mashrabiyah, become as vocabulary of many Islamic cities in the Hijazi region such as Jeddah in Saudi Arabia, and even for a number of Islamic historic cities such as Istanbul and Cairo. These architectural vocabularies are the main cause of the beauty of these heritage. However, there is a big gap in both the Islamic architectural library and the Hijazi architectural library to provide these unique elements. Besides, both Islamic and Hijazi architecture contains a huge amount of information which has not yet been digitally classified according to period and styles. Due to this issue, this paper will be focusing on developing of Heritage BIM (HBIM) standards and the HAOL library to reduce the cost and the delivering time for heritage and new projects that involve in Hijazi architectural styles. Through this paper, the fundamentals of Hijazi architecture informatics will be provided via developing framework for HBIM models and standards. This framework will provide schema and critical information, for example, classifying the different shapes, models, and forms of structure, construction, and ornamentation of Hijazi architecture in order to digitalize parametric building identity.

Parametric Modelling for Hbim: Design of Window Library for Rural Building

“…Subsequently, these serve as a basis for designing and building parametric object libraries. In recent years, several specialized publications have been published describing library modelling for vaulting systems [4-6, 15-18] -irregular walls, vaults, atriums, columns and pillars; a particular type of architectural element -Falconatura [3], Roshan [12,19], portals from the Etnean region [20]; architectural style [12,21,22] etc.…”

“…In recent years, several professional publications have been published dealing with the use of BIM in the field of cultural heritage management, e.g. [3][4][5][6][10][11][12], etc. The summary and synthesis of these aims are illustrated in Figure 2.…”

“…Therefore, terrestrial laser scanning (TLS) or close range photogrammetry, using Image Based Modelling and Rendering (IBMR) technology, are often used for detailed metric surveys, e.g. [3][4][5][6][10][11][12]. On-site, detailed surveys should be complemented by observations of GNSS and total stations [10].…”

Construction the Bridge Pier as Parametric Object Using Autodesk Revit

“…Опора має досить складну форму, тому для кожного еле-мента, що буде створений як окремий геомет-ричний об'єкт, потрібно одразу задавати необ-хідні параметри та перевіряти коректність змі-ни цих параметрів [6][7][8][9][10][11][12][13].…”

“…Створення параметричних інформаційних моделей -один з найпрогресивніших напрямків комп'ютерного проектування, але не достатньо ще вивчений. Як в літературі, так і в інтернет-ресурсах, пара-метризація розглядається на прикладі приміти-вних об'єктів [6][7][8][9][10][11][12][13]. Що стосується створення параметричних моделей елементів мостових переходів -у літературі така інформація не зу-стрічається, отже запропонована вперше.…”
