With growing demands on the construction industry managing both production cost and transaction costs has become critical to the success of a project. Although much emphasis is placed the accuracy of estimates which are a combination of materials and labor, not enough attention is focused on the cost of project management [1]. The emergence of new technologies for use in design, estimating and management provide the opportunity to control the total project cost while balancing the quality of the work against the time spent managing it.
The equation presented by [1] expresses the cost of project management as a combination of client costs and contractor costs over total project cost.

Over the past two decades, the construction industry has begun a transitioning from the traditional project delivery model,

to an alternate design-build delivery system.

State laws have historically prevented architects and engineers from preforming the duties of general contractors allowing contractors to corner the market on the design-build. However, the American Institute of Architects has recently began publishing a variety of agreements broadening the scope for individuals and companies throughout the entire industry to assume the role of project head.

Time and cost overruns are common in the construction industry. These are on average nearly 30% as explained by [2]. An early focus on planning can reduce the overall project time and improve the outcome significantly. Feasibility studies lead by the various parties involved in project can be used assess and manage the risks. Over the design, development and construction phases, these reports become increasingly detailed and more accurate compared to the speculative nature of original pro forma.

The implementation of Building Information Modeling (BIM) is a digital representation of a construction project and a method of organizing that data throughout its lifecycle [3]. The usefulness of this method however depends upon the size, scope and complexity of a project. The limitations of the software, additional hardware costs and steep learning curves involved with its advanced features must be considered. Decisions about the benefits should be made based on the time allocated for using this method over older more traditional practices.
One area of innovation that has seen major advances recently is that of mobile technology. Mobile devices are being used in nearly all phases of construction. This allows for faster communication between every person involved with project. The downside however is that it has created unrealistic expectations about the time required to complete actual tasks. The table presented by [4] list a variety of mobile applications, their intend uses, and area of application. Although it is unlikely that the time involved in actual labor can be reduced, these tools do provide more efficient and effective means of managing that work. This further helps to control cost through better coordination, reducing the risk improper scheduling and costly rework. It can provide real-time assessment of construction cost providing project managers more ability to keep the work on time and within budget.
