AGC Lean Unit 6

Choosing by advantages (CBA)
A process that lists the advantages of options and helps quickly identify the options with the most advantages. This process avoids the double counting inherent in listing pros and cons when in one option is also the con in another.
Cross functional teams
Teams composed of key participants from all project stages including design, construction, installation, commissioning, operations, maintenance, decommissioning, etc. These teams focus on finding solutions with systems level thinking and are structured along systems instead of skill sets.
The time it takes to complete one finished unit of a process. For example, the time it takes to load a haul, build one course of brick/block, form a footing, etc.
A process that might be called rapid, full scale prototyping that focuses on people, process, and planning. The process uses a simulated work environment and has actual star simulate the work to be performed in the space to learn more about the spaces required for efficient operation in the designed work environment.
First run study
Trial execution of a process in order to determine the best means, methods, and sequencing etc. to perform it. First run studies are done at least a few times ahead of the scheduled execution of the process, while there is time to acquire different or additional prerequisites and resources. They may also be performed during design as a basis for evaluating options or designing the portion of the work.
Future state mapping
A process to understand and document how work or users will process through the completed project.
Buffer created by maintaining a stock of critical material. Lack of these materials poses a threat to reliable workflow on site.
Finding methods to assemble materials in the most efficient way possible off or on site.
The process that brings all players together early in the project to provide input in the design and increase value by using the expertise of architects, engineers, construction managers, and specialty contractors to ensure the design takes advantage of the best construction and installation procedures that facilitate facility operation and maintenance. Design decisions are deferred to the last responsible moment to take advantage of information discovered or developed during the design process.
Lean project delivery system (LPDS)
A representation of the development and delivery of a project from determine that which helps clients better achieve their business purposes through final use. Positive iterations are encouraged within each phase. Production control, work structuring and learning are continuous functions.
Lean supply chain
The elimination of waste by creating efficient methods of procurement of materials and equipment.
Improving one part of the project but not the whole
Make ready plan
Also known as the six week look ahead schedule, results in what can be done (get to can by constraint removal from the should's).
Taking prefabricated components and building them into a subsection of a larger space, such as a prison cell with beds already attached; bathrooms with plumbing already hooked up, etc. Process allows for greater standardization and reduces the tome spent on the job site.
Represents the work performed to complete the transformation of materials.
Focus on making work happen by removing constraints ahead of time as much as possible.
Assembling components, usually conducted off site either by the supplier or the subcontractor, so that view pieces need to be installed at the job site.
Represents flow of material/information in time and space as it is being transformed. The construction process can be broken down into two levels: process and operation.
Every production process exhibits some measure of variation in its results. The average of these results is defined as the process mean.
Reliably, efficiently and economically allocating resources to day to day functions such that project level milestones and phases are completed.
An individual or a group of individuals performing a common production task.
The number of similar products produced and sold by the organization. The product mix can vary from one of a kind to large volume organizations. Construction companies produce one of a kind products whereas companies in the automobile industry, for example, produce a large volume of similar products.
Set based design
A technique of lean design, which allows for evaluation of alternatives by deferring design decisions to the last responsible moment. A set of possible options is developed for product design and production design, with the one that best meets all stakeholder's needs and purposes chosen at the last responsible moment.
Target value design
A collaborative design process involving designers, builders, suppliers, estimators and the owner co-located in one place to produce collaboratively a design that provides the best value for the owner that can be constructed within a defined budget. The team designs to the budget, and then redesigning to eliminate overruns.
These assignments have met all the criteria needed to start but the crew may hold off starting these activities in case other, critical work can't start as planned. Completion or non completion of these activities are not recorded or counted in calculation of PPC.
The progression of work within a trade from one trade to another. Reliable workflow is very important in maintaining project cost and time commitment.
The extent to which one can depend on the occurrence of the transfer of material or information from one production unit to another or within a production unit.
