PERT, as seen, has been utilized in scheduling tasks as significant as U.S. military operations, but has further shown to be significantly useful in the construction field. Not only has PERT proven a viable tool in the scheduling of construction projects, but it has been noted to aid significantly in the research and development of projects. Even with an extensive experience base, construction operations have enough uncertainly that the construction manager can learn several important lessons from a brief overview of the PERT procedure including proper estimates of modal duration in terms of probability of accomplishing certain activities within the time period specified (Clough, Sears and Sears, 2008, pp. 366-67).
Gantt Charts and Construction Scheduling
A Gantt chart is a type of bar chart that illustrates a project schedule, including the start and finish dates of the terminal elements and summary elements of a project (Morris, 1994, p. 18). While considered common-place as a project management tool in construction and other fields today, Gantt charts were initially considered a radical concept and innovation of worldwide importance in the 1920s, and the concept gained significant public attention, leading to its use on large construction projects like the Hoover Dam and United States interstate highway system (Gantt, 2011, p.1). Despite the misconception that Gantt charts have essentially been overshadowed by more technologically-savvy programs, its basis in successful projects development and schedule have kept Gantt charts relevant in today's more technologically-based environment.
Conclusion
As seen, tools such as CPM, PERT and Gantt charts have been designed specifically...
In this regard, Greenspan and his associates report that, "The construction manager at-risk, who also acts as the general contractor, is integrally involved in the design process, assisting with design, constructability reviews, cost estimating, and scheduling" (p. 14). In this emerging capacity, construction managers must possess a thorough knowledge of construction materials and be able to identify where cost savings can be achieved through alternative uses of different materials.
This approach brings down the costs involved, the chances of delay in product release and the gives the user an option to update their requirements in successive iterative steps (Jacobson & Rumbaugh 1999, pp. 3-13). CHAPTER 2 Oracle and Microsoft SQL Server are among the most widely used databases with a large range of features with regards to their techniques of development and deployment. Both the Oracle 10g and SQL Server
Even a good plan cannot account for all subcontracting-related delays. Intuitively it might seem that a plan of such magnitude could not be completed on time, at least not with so many subcontractors. When in doubt, common sense should 'win out' when allowing for delays. The only conceivable way for a good baseline plan to have accounted for more contingencies within the project would be to work with all subcontractors

A construction manager must be prepared for anything and everything, and a degree can give a manager a broad-based sphere of knowledge and additional flexibility when serving the needs of a client. Technical knowledge of materials and even computers may be demanded at times: "Construction managers determine the best way to get materials to the building site and the most cost-effective plan and schedule for completing the project. They
Executive Summary ODR has been slow to modernize and take advantage of the software that is available to streamline business practices and drive efficiency. An example of this is the company’s current manual process for rentals. The manual nature of the process not only makes it inefficient at the time of the rental, but makes it very difficult to maintain documentation over the long run. Tracking damages has been a particular
