Construction Project Management is the overall planning, coordination and control of a
project from inception to completion aimed at meeting a clients requirements in order to
produce a functionally and financially viable project that will be complete mingement (CPM) isproject management that applies to the construction sector (3rd Forum International
Construction Project Management 26th/27 June 2003 in Berlin).
TheConstruction Management Association of America (CMAA)(a primary US construction
management certification and advocacy body) says the 120 most common responsibilities of a
Construction Manager fall into the following 7 categories: Project Management Planning, CostManagement, Time Management, Quality Management, Contract Administration, Safety
Management, and CM Professional Practice which includes specific activities like defining the
responsibilities and management structure of the project management team, organizing and
leading by implementing project controls, defining roles and responsibilities and developingcommunication protocols, and identifying elements of project design and construction likely to
give rise to disputes and claims.

:
1. Specifying project objectives and plans including delineation of scope, budgeting,scheduling, setting performance requirements, and selecting project participants.
2. Maximizing resource efficiency through procurement of labor, materials and equipment.3. Implementing various operations through proper coordination and control of planning,
design, estimating, contracting and construction in the entire process.4. Developing effectivecommunicationsand mechanisms for resolving conflicts

[edit] Study and practice
Construction Management education comes in a variety of formats: formal degree programs
(one-yearassociate degree; four-yearbaccalaureate degree,masters degree,project management,operations managementengineer degree,doctor of philosophydegree,postdoctoral researcher);
on-job-training; and continuing education / professional development. For information on degree
programs, reference ACCE, the American Council for Construction Education, or ASC, the
Associated Schools of Construction.
According to the American Council for Construction Education (the academic accrediting bodyof construction management educational programs in the U.S.), the academic field of
construction management encompasses a wide range of topics. These range from general
management skills, to management skills specifically related to construction, to technical
knowledge of construction methods and practices. There are many schools offering Construction
Management programs, including some that offer a Masters degree.[4][5]

Skyscrapersunder construction inPanama City,Panama.
Typically the construction industry includes three parties: an owner, a designer(architector
engineer), the builder (usually called thegeneral contractor). Traditionally, there are twocontracts between these parties as they work together to plan, design, and construct the project.
[6]
The first contract is the owner-designer contract, which involves planning, design, and
construction administration. The second contract is the owner-contractor contract, whichinvolves construction. An indirect, third-party relationship exist between the designer and the
contractor due to these two contracts.
An alternate contract or business model replaces the two traditional contracts with three contracts:
owner-designer, owner-construction project manager, and owner-builder. The construction
project management company becomes an additional party engaged in the project to act as an
advisor to the owner, to which they are contractually tied. The construction manager's role is toprovide construction advice to the designer, on the owner's behalf, design advice to the
constructor, again on the owner's behalf, and other advice as necessary.
[edit] Design, bid, build contracts
Design, bid, builddescribes the prevailing model of construction management in which the
general contractor is engaged through a tender process after the designs have been completed by
the architect or engineer.
[edit] Design and build contracts

Recently a different business model has become more popular. Many ownersparticularly
government agencies have let out contracts which are known as Design-Build contracts. In this

type of contract, the construction team is known as the design-builder. They are responsible for
taking a concept developed by the owner, completing the detailed design, and then pending the
owner's approval on the design, they can proceed with construction.Virtual Design andConstructiontechnology has enabled much of the ability of contractors to maintain tight
construction time
There are two main advantages to using a design-build contract. First, the construction team is
motivated to work with the design team to develop a design with constructability in mind. In that
way it is possible for the team to creatively find ways to reduce construction costs withoutreducing the function of the final product. The owner can expect a reduced price due to the
increased constructability of the design.
The other major advantage involves the schedule. Many projects are given out with an extremely
tight time frame. By letting out the contract as a design-build contract, the contractor is
established, and early mobilization and construction activities are able to proceed concurrently
with the design. Under a traditional contract, construction cannot begin until after the design is
finished, the project is bid and awarded, and the team can mobilize. This type of contract cantake months off the finish date of a project.
The major problem[7]
with design-build contracts is the inherent conflict of interest. In a standard
contract the designer is responsible to the owner to review the work of the builder to be sure the
products and methods meet specifications and codes. The builder as a construction professionalexperienced working with many designers is attuned to picking up design flaws which would go
uncaught or unmentioned when builder is also designer. The owner may be more likely to get a
building that is over-designed in order to increase costs and profits for the design-builder, or built
with lesser grade products to maximize profits. If time is of the essence, a design andconstruction contracts can be awarded separately, with bidding taking place on preliminary plans
in a not-to-exceed contract in lieu of a single firm design-build contract.

3d image[edit] Agency CM
Construction Cost Management is a fee-based service in which the Construction Manager (C.M)
is responsible exclusively to the owner and acts in the owner's interests at every stage of theproject. The construction manager offers advice, uncolored by any conflicting interest, on
matters such as:
Optimum use of available funds; Control of the scope of the work; Project scheduling; Optimum use of design and construction firms' skills and talents; Avoidance of delays, changes and disputes; Enhancing project design and construction quality; Optimum flexibility in contracting and procurement. Cash flow Management.
Comprehensive management of every stage of the project, beginning with the original conceptand project definition, yields the greatest possible benefit to owners from Construction
Management. As time progresses beyond the pre-design phase the CM's ability to effect cost
savings diminishes. The Agency CM can represent the owner by helping to select the designteam as well as the construction team and manage the design preventingscope creep, helping the
owner stay within a pre-determined budget by performing Value Engineering, Cost/Benefit
Analysis and Best Value Comparisons.
[edit] CM at-risk
CM at-risk is a delivery method which entails a commitment by the construction manager todeliver the project within aGuaranteed Maximum Price(GMP), in most cases. The construction
manager acts as consultant to the owner in the development and design phases, (often referred to
as "Preconstruction Services"), but as the equivalent of a general contractor during theconstruction phase. When a construction manager is bound to a GMP, the most fundamentalcharacter of the relationship is changed. In addition to acting in the owner's interest, the
construction manager must manage and control construction costs to not exceed the GMP, which
would be a financial hit to the CM company.
CM at riskis a global term referring to a business relationship of Construction contractor, Owner
and Architect / Designer. Typically, a CM At Risk arrangement eliminates a "Low Bid"construction project. A GMP agreement is a typical part of the CM and Owner agreement
somewhat comparable to a "Low Bid" contract, but with a number of adjustments in
responsibilities required by the CM. The following are some of the potential benefits of a CM At
Risk arrangement:
Budget management: Before design of a project is completed ( 6 months to 1 years ofcoordination between Designer and Owner), the CM is involved with estimating the cost of

constructing a project based on the goals of the Designer and Owner (design concept) and the
overall scope of the project. In balancing the costs, schedule, quality and scope of the project,
decisions can be made to modify the design concept instead of having to spend a considerableamount of time, effort and money re-designing and/or modifying completed construction
documents. For instance, if the Owner decides to spend more money or obtain more funding for
the project, adjustments can be made to the project more cost-effectively without having tocomplete construction documents as a predecessor to pricing. To manage the budget beforedesign is done, construction crews are mobilized, the CM is often spending significant resources
each week with onsite management, major items are purchased, etc., etc., is a much more
efficient use of everyone's time, effort, Architect / Designer's costs, and the CM's GeneralConditions costs, AND delivering to the Owner a design within his budget.
