THE ROLE OF FABRICATION IN DESIGN PROCESS

ABSTRACT

 

This research attempts to formulate key aspects of design methodological framework which coalescing with fabrication role to build artifacts as part of the creative design process.

 

When the main question of architecture field is about “Target of architectural design”, comprehensive response would be concentrated on building the physical, factual and tangible phenomenon of that. This answer gives ride to another question that: “How it could be possible to reach to design production? “This matter propounds the importance and exigency of focus on choosing “Process based design” as the main approach.

 

As the reason of the digital contemporary era potentials and also, existence of complexity in forms, functions and management of most projects, absolutely, Choosing different approach in proportion of past , is necessary . All these conditions need a holistic view to design problems and cause to integrity of all parts of design fabrication process.

 

This approach to matter defines the parametric view, inherent to contemporary architecture context. Thus, composition of parametricism with characters of digital era , in according to the use of CAD(computer aided design ) and CAM( computer aided manufacturing) capabilities in design and fabrication / construction process , can lead to the regularity and computational inspiration in design process . Rule - bound and pattern based design can prepare the range of variant scales of models and prototypes which can test every matter of fabrication problems and eventually, materialize real world scale construction.

 

During the spiral process of design, expressions of fabrication play the virtual role of generating the design ideas according to some models of rapid prototyping. Actually, the reason of integrity in design fabrication process is the existence of joint language between variant design software and digital techniques and tools of fabrication like LCs and RPs

 

This methodology of thinking about design fabrication create the integrity needed between spiral process of design fabrication and it’s so many feedbacks with sequential construction process .The result of  this happening , make a connection of academic architectural pedagogy and profession of this field . So, concentrating on design fabrication and fabricating design which completely considering the matter of construction and constructability, describe integrity of design process.

 

In correspondence with all explained , In this method of design research specially in educational part , so many problems which always are ignored and neglected in academic years of learning architecture like “ Details ”,” Materials ”, “assemblies techniques ”and some tools and techniques related to them , become highlighted as the content of research should be explored and evaluated.

 

In this research, a digital design fabrication method is introduced. The DDF method is the two stages process of working that integrates generative computing and RP in to one process. Thus , together ,they support a process to generate diverse candidate artifacts as solutions to design problems. This method demonstrates a process of design situated between conceptual design and real world construction.

Fundamental Structure of Research

Parametricism

 

Parametricism is a mature style. That the parametric paradigm is becoming pervasive in contemporary architecture and design is evident for quite some time. There has been talk about versioning, iteration and mass customization etc. for quite a while within the architecture avant-garde discourse. The fundamental design that has come to the fore in this tendency has already been formulated at the beginning of the 1990s with the key slogan of “continuous differentiation”. Since then there has been both a widespread, even hegemonic dissemination of this tendency as well as a cumulative buildup of virtuosity, resolution and refinement within it. This development was facilitated by the attendant development of parametric design tools and scripts that allow the precise formulation and execution of intricate correlations between elements and subsystems. The shared concepts, computational techniques, formal repertories, and tectonic logics that characterize this work are crystalizing into a solid new hegemonic paradigm for architecture. One of the most pervasive current techniques involves populating modulated surfaces with adaptive components. Components might be constructed form multiple elements constrained/cohered by associative relations so that the overall component might sensibly adapt to various local conditions. As they populate a different iated surface their adaptation should accentuate and amplify this differentiation. This relationship between the base component and its various instantiations as different points of insertion in the “environment” is analogous to the way a single geno-type might produce a differentiated population of phenol-types in response to divers environmental conditions.

Integrated Design

 

Integrated design is a collaborative method for designing buildings which emphasizes the development of a holistic design.

Conventional building design usually involves a series of hand-offs from owner to architect, from builder to occupant. This path does not invite all affected parties into the planning process, and therefore does not take into account their needs, areas of expertise or insights. In some cases, using the conventional method, incompatible elements of the design are not discovered until late in the process when it is expensive to make changes. In contrast, the integrated design process requires multidisciplinary collaboration, including key stakeholders and design professionals, from conception to completion. Decision-making protocols and complementary design principles must be established early in the process in order to satisfy the goals of multiple stakeholders while achieving the overall project objectives.

 

In addition to extensive collaboration, integrated design involves a “whole building design” approach. A building is viewed as an interdependent system, as opposed to an accumulation of its separate components (site, structure, systems and use). The goal of looking at all the systems together to is make sure they work in harmony rather than against each other.

 

Integrated design has evolved in conjunction with the rise of multidisciplinary design firms and sustainable design. It frequently begins with a charrette or eco-charrette, an intensive design workshop, in which many stakeholders gather to set goals and identify strategies for achieving the desired outcomes.

Continuous Surface inherently has the Potential of INTERNAL & EXTERNAL Spaces composition

 

This surface is the second skin of the facade which pulls itself toward the inside of the building .In this way creates two open terraces and then continuesits path completely inside of the building by TRANSFORMING in to the large INTERNAL VOID designed in the process
