Over the course of any construction project, the work scope may change. Change is a normal and expected part of the construction process. Changes can be the result of necessary design modifications, differing site conditions, material availability, contractor-requested changes, value engineering, and impacts from third parties, to name a few.
Process decision program chart. A useful way of planning is to break down tasks into a hierarchy, using a tree diagram. The process decision program chart (PDPC) extends the tree diagram a couple of levels to identify risks and countermeasures for the bottom level tasks. Different shaped boxes are used to highlight risks and identify possible ...
In construction, commissioning or commissioning process (often abbreviated Cx) [1] [2] [3] is an integrated, systematic process to ensure, that all building systems perform interactively according to the "Design Intent", through documented verification. The commissioning process establishes and documents the "Owner's Project Requirements (OPR ...
Construction project management concepts. Construction – in the fields of architecture and civil engineering, is a process that consists of the building or assembling of infrastructure. Far from being a single activity, large scale construction is a feat of multitasking. Normally the job is managed by the project manager and supervised by the ...
Step four involves more developed designs and a detailed cost estimate. Step five is the construction documents or the plan. Bidding and contracting for the project follows as step six. Construction then will take place as step seven. The final step, step eight, in the site design process is occupation and management of the site.
A site plan or a plot plan is a type of drawing used by architects, landscape architects, urban planners, and engineers which shows existing and proposed conditions for a given area, typically a parcel of land which is to be modified. Sites plan typically show buildings, roads, sidewalks and paths/trails, parking, drainage facilities, sanitary ...
The EPC contractor coordinates all design, procurement and construction work and ensures that the whole project is completed as required and in time. They may or may not undertake actual site work. EPC companies are often used in large-scale projects, such as power plants, refineries, chemical processing facilities, infrastructure projects, and ...
With the traditional design–bid–build process, a complete set of construction documents and specifications describes what the builder agrees to build and serves as the heart of the contract. On Fast-track projects, the design, construction documents and specifications are incomplete, so setting the final cost presents problems.
