Learning to Build - Answers Often, the decision of which building materials to use is based on
economics. But what
costs less at first may cost more throughout its life cycle through maintenance and
replacement, or energy use
Sustainability: - Answers sustainability may be defined as meeting the needs of the present
generation without compromising the ability of future generations to meet their needs
U.S. Green Building Council, - Answers buildings account for 30% to 40% of the world's energy
use and associated greenhouse gas emissions
LEED (Leadership in Energy and Environmental Design) - Answers standard for measuring the
sustainability of construction
The Work of the Design Professional: - Answers Designers develop the building plan for
effective design and to comply with the legal constraints like zoning ordinances and building
codes along with any other constraints such as under the American Disabilities Act (ADA), the
Fair Housing Act, EPA, OSHA, and other laws and rules.
Building Codes: - Answers International Residential Code (IRC) building code for 1 & 2 family

Fast Track or Phased construction - Answers aims to reduce the time required to complete the
project by overlapping the design and construction of various project parts.
Construction Scheduling: - Answers Successful construction requires a detailed understanding
of the tasks required and their interdependencies. Planning and scheduling involves analysis of
these relationships between the different project activities using Gantt charts (bar charts) and
Network Diagrams (flow charts) to understand which activities are bottlenecks to progress.
These bottlenecks are considered critical activities. A critical path can be charted through the
project where these critical activities are focused, to keep the project on schedule.
Approval of Construction Documents: - Answers Approved plans and permit must be kept at the
site of work. [IRC Ch#1
and IBC Ch#1]
