Design–build (or design/build, and abbreviated D–B or D/B accordingly), also known as alternative delivery, [1] is a project delivery system used in the construction industry. It is a method to deliver a project in which the design and construction services are contracted by a single entity known as the design–builder or design–build ...
Design–bid–build. Design–bid–build (or design/bid/build, and abbreviated D–B–B or D/B/B accordingly), also known as Design–tender (or "design/tender"), traditional method, or hardbid, is a project delivery method in which the agency or owner contracts with separate entities for the design and construction of a project.
Project delivery methods defines the characteristics of how a construction project is designed and built and the responsibilities of the parties involved in the construction (owner, designer and contractor). [1] They are used by a construction manager who is working as an agent to the owner or by the owner itself to carry-out a construction ...
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
The fast-tracking of the project is therefore achieved through the integration of design and construction phases. Fast-track is more difficult to manage than the traditional design–bid–build process. It requires detailed knowledge of the process, effective planning, integrity and close coordination among the organizations executing the work.
If speed is important, design and construction contracts can be awarded separately; bidding takes place on preliminary plans in a not-to-exceed contract instead of a single firm design-build contract. The major problem [11] with design-build contracts is an inherent conflict of interest. In a standard contract the architect works for the owner ...
Building design, also called architectural design, refers to the broadly based architectural, engineering and technical applications to the design of buildings. All building projects require the services of a building designer, typically a licensed architect. Smaller, less complicated projects often do not require a licensed professional, and ...
