Building Design Process


In the design process, we tend to think first of the larger holistic pattern before we consider the elemental structural units that make up the larger whole. So as we strategize to develop a structural plan for a
building, we should consider both the essential qualities of the architectural composition and the nature and configuration of the structural elements. This leads to a series of fundamental questions:

Building Design
Is there an overarching form required or does the architectural composition consist of articulated parts? If so, are these parts to be hierarchically ordered
Are the principal architectural elements planar or linear in nature?

Building Program
Are there required relationships between the desirable scale and proportion of the program spaces, the spanning capability of the structural system, and the resulting layout and spacing of supports?
Is there a compelling spatial reason for one-way or two-way spanning systems?
 

Systems Integration
How might the mechanical and other building systems be integrated with the structural system?

Code Requirements
What are the building code requirements for the intended use, occupancy, and scale of building?
What is the type of construction and what are the structural materials required?
 

Economic Feasibility
How might material availability, fabrication processes, transportation requirements, labor and equipment requirements, and erection time influence the choice of a structural system?
Is there a need to allow for expansion and growth either horizontally or vertically?

Legal Constraints
There exists a regulated relationship between the size (height and area) of a building and its intended use, occupancy load, and type of construction. Understanding the projected scale of a building is
important because a building’s size is related to the type of structural system required and the materials that may be employed for its structure and construction.
 
Zoning Ordinances
Zoning ordinances constrain the allowable bulk (height and area) and shape of a building based on its location in a municipality and position on its site, usually by specifying various aspects of its size.
The size and shape of a building are also controlled indirectly by specifying the minimum required distances from the structure to the property lines of the site in order to provide for air, light, solar
access, and privacy.
