Construction as an Industry
The construction industry is composed of five sectors: residential, commercial, heavy civil, industrial, and environmental. A construction manager holds the same responsibilities and completes the same processes in each sector. All that separates a construction manager in one sector from one in another is the knowledge of the construction site. This may include different types of equipment, materials, subcontractors, and possibly locations.
The Role of a Contractor
A contractor is assigned to a construction project once the design has been completed by the architect or is still in progress. This is done by going through a bidding process with different contractors. The contractor is selected by using one of three common selection methods: low-bid selection, best-value selection, or qualifications-based selection. this is the main role of a contractor.
Skills Needed for Construction Management
The functions of Construction management typically include the following:
- Specifying project objectives and plans including delineation of scope, budgeting, scheduling, setting performance requirements, and selecting project participants.
- Maximizing the resource efficiency through procurement of labor, materials and equipment.
- Implementing various operations through proper coordination and control of planning, design, estimating, contracting and construction in the entire process.
- Developing effective communications and mechanisms for resolving conflicts.:
The Construction Management Association of America (a 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, Cost Management, Time Management, Quality Management, Contract Administration, Safety Management, and CM Professional Practice. CM professional practice includes specific activities, such as defining the responsibilities and management structure of the project management team, organizing and leading by implementing project controls, defining roles and responsibilities, developing communication protocols, and identifying elements of project design and construction likely to give rise to disputes and claims.
The Five Types of Construction
- Residential: Residential construction includes individual homes, apartments, condominiums, townhouses, and other housing types.
- Commercial: This refers to construction dealing with the needs of commerce, trade, and government. Examples include shopping centers, schools, banks, hospitals, theaters, and government buildings.
- Heavy Civil: The construction of transportation infrastructure such as roads, bridges, railroads, tunnels, and airports. Dams are also included here, but other water-related infrastructure is considered environmental.
- Industrial: Buildings and other constructed items used for product production, including chemical plants, steel mills, oil refineries, manufacturing plants, and pipelines.
- Environmental: Environmental construction used to be part of heavy civil, but is now its own section, dealing with projects that improve the environment. Some examples are sanitary sewers, waste management, and clean water.

Obtaining the Project
A bid is given to the owner by construction managers that are willing to complete their construction project. A bid tells the owner how much money they should expect to pay the construction management company in order for them to complete the project.
- Open Bid: An open bid is used for public projects. Any and all contractors are allowed to submit their bid due to public advertising.
- Closed Bid: A closed bid is used for private projects. A selection of contractors are sent an invitation for bid so only they can submit a bid for the specified project.
- Low-bid selection: This selection focuses on the price of a project. Multiple construction management companies submit a bid to the owner that is the lowest amount they are willing to do the job for. Then the owner usually chooses the company with the lowest bid to complete the job for them.
- Best-value selection: This selection focuses on both the price and qualifications of the contractors submitting bids. This means that the owner chooses the contractor with the best price and the best qualifications. The owner decides by using a request for proposal (RFP), which provides the owner with the contractor's exact form of scheduling and budgeting that the contractor expects to use for the project.
- Qualifications-based selection: This selection is used when the owner decides to choose the contractor only on the basis of their qualifications. The owner then uses a request for qualifications (RFQ), which provides the owner with the contractor's experience, management plans, project organization, and budget and schedule performance. The owner may also ask for safety records and individual credentials of their members.
- Lump-sum: This is the most common type of contract. The construction manager and the owner agree on the overall cost of the construction project and the owner is responsible for paying that amount whether the construction project exceeds or falls below the agreed price of payment.
- Cost-Plus-Fee: This contract provides payment for the contractor including the total cost of the project as well as a fixed fee or percentage of the total cost. This contract is beneficial to the contractor since any additional costs will be paid for even though they were unexpected for the owner.
- Guaranteed Maximum Price: This contract is the same as the cost-plus-fee contract although there is a set price that the overall cost and fee do not go above.
- Unit-Price: This contract is used when the cost cannot be determined ahead of time. The owner provides materials with a specific unit price to limit spending.
The design stage contains a lot of steps: programming and feasibility, schematic design, design development, and contract documents. It is the responsibility of the design team to ensure that the design meets all building codes and regulations. It is during the design stage that the bidding process takes place.
- Programming and feasibility: The needs, goals, and objectives must be determined for the building. Decisions must be made on the building size, number of rooms, how the space will be used, and who will be using the space. This must all be considered to begin the actual designing of the building.
- Schematic design: Schematic designs are sketches used to identify spaces, shapes, and patterns. Materials, sizes, colors, and textures must be considered in the sketches.
- Design development (DD): This step requires research and investigation into what materials and equipment will be used as well as their cost.
- Contract documents (CDs): Contract documents are the final drawings and specifications of the construction project. They are used by contractors to determine their bid while builders use them for the construction process. Contract documents can also be called working drawings.
The pre-construction stage begins when the owner gives a notice to proceed to the contractor that they have chosen through the bidding process. A notice to proceed is when the owner gives permission to the contractor to begin their work on the project. The first step is to assign the project team which includes the project manager (PM), contract administrator, superintendent, and field engineer.
- Project manager: The project manager is in charge of the project team.
- Contract administrator: The contract administrator assists the project manager as well as the superintendent with the details of the construction contract.
- Superintendent: It is the superintendent's job to make sure everything is on schedule including flow of materials, deliveries, and equipment. They are also in charge of coordinating on-site construction activities.
- Field Engineer: A field engineer is considered an entry-level position and is responsible for paperwork.
During the pre-construction stage, a site investigation must take place. A site investigation takes place to discover if any steps need to be implemented on the job site. This is in order to get the site ready before the actual construction begins. This also includes any unforeseen conditions such as historical artifacts or environment problems. A soil test must be done to determine if the soil is in good condition to be built upon.
The procurement stage is when labor, materials and equipment needed to complete the project are purchased. This can be done by the general contractor if the company does all their own construction work. If the contractor does not do their own work, they obtain it through subcontractors. Subcontractors are contractors who specialize in one particular aspect of the construction work such as concrete, melding, glass, or carpentry. Subcontractors are hired the same way a general contractor would be, which is through the bidding process. Purchase orders are also part of the procurement stage.
- Purchase orders: A purchase order is used in various types of businesses. In this case, a purchase order is an agreement between a buyer and seller that the products purchased meet the required specifications for the agreed price.
The construction stage begins with a pre-construction meeting brought together by the superintendent. The pre-construction meeting is meant to make decisions dealing with work hours, material storage, quality control, and site access. The next step is to move everything onto the construction site and set it all up.
At this stage, construction monitoring and supervision is of great importance to ensure that a project is completed on time and on budget, while meeting all relevant regulations and quality standards.
Contractor progress payment schedule
A Contractor progress payment schedule is a schedule of when (according to project milestones or specified dates) contractors and suppliers will be paid for the current progress of installed work.
Progress payments are partial payments for work completed during a portion, usually a month, during a construction period. Progress payments are made to general contractors, subcontractors, and suppliers as construction projects progress. Payments are typically made on a monthly basis but could be modified to meet certain milestones. Progress payments are an important part of contract administration for the contractor. Proper preparation of the information necessary for payment processing can help the contractor financially complete the project. 
Once the construction has been completed there are specific steps that must be taken to prepare the building for occupancy.
- Project punchout: A project punchout means that the project must be looked at for any issues before it is considered completely finished. Issues may include replacing a cracked tile on the floor or changing the color of paint. A list is created containing these issues and it is known as a punch list or a snag list.
- Substantial completion: The architect for the project determines if the building meets every requirement and issues a certificate of substantial completion. This certificate announces the official completion of the project.
- Final inspection: A final inspection is done by the building official once the certificate of substantial completion has been issued.
- Certificate of Occupancy: A certificate of occupancy is issued by the building official which informs the owner that it is now safe to occupy. This is issued by the building official after the final inspection.
- Commissioning: This is the process of testing systems and equipment to ensure that they are working correctly. Then the owner must be trained to properly operate the systems and equipment in the building.
- Final documentation: This provides information on the building to the owner for future references. This includes warranties, operation manuals, inspection and testing reports, and record drawings.
- Final completion: Final completion occurs when all required paperwork and documentation is completed, including payments to the contractor.
Once the owner moves into the building, a warranty period begins. This is to ensure that all materials, equipment, and quality meet the expectations of the owner that are included within the contract.
Issues Resulting from Construction
Dust and Mud
- Storm water pollution: As a result of construction, the soil is displaced from its original location which can possibly cause environmental problems in the future. Runoff can occur during storms which can possibly transfer harmful pollutants through the soil to rivers, lakes, wetlands, and coastal waters.
- Endangered species: If endangered species have been found on the construction site, the site must be shut down for some time. The construction site must be shut down for as long as it takes for authorities to make a decision on the situation. Once the situation has been assessed, the contractor makes the appropriate accommodations to not disturb the species.
- Vegetation: There may often be particular trees or other vegetation that must be protected on the job site. This may require fences or security tape to warn builders that they must not be harmed.
- Wetlands: The contractor must make accommodations so that erosion and water flow are not affected by construction. Any liquid spills must be maintained due to contaminants that may enter the wetland.
- Historical or Cultural artifacts: Artifacts may include arrowheads, pottery shards, and bones. All work comes to a halt if any artifacts are found and will not resume until they can be properly examined and removed from the area.
Construction Activity Documentation
Project meetings take place at scheduled intervals to discuss the progress on the construction site and any concerns or issues. The discussion and any decisions made at the meeting must be documented.
Diaries, Logs, and Daily Field Reports
Diaries, logs, and daily field reports keep track of the daily activities on a job site each day.
- Diaries: Each member of the project team is expected to keep a project diary. The diary contains summaries of the day's events in the member's own words. They are used to keep track of any daily work activity, conversations, observations, or any other relevant information regarding the construction activities. Diaries can be referred to when disputes arise and a diary happens to contain information connected with the disagreement. Diaries that are handwritten can be used as evidence in court.
- Logs: Logs keep track of the regular activities on the job site such as phone logs, transmittal logs, delivery logs, and RFI (Request for Information) logs.
- Daily Field Reports: Daily field reports are a more formal way of recording information on the job site. They contain information that includes the day's activities, temperature and weather conditions, delivered equipment or materials, visitors on the site, and equipment used that day.
- Mediation: Mediation uses a third party mediator to resolve any disputes. The mediator helps both disputing parties to come to a mutual agreement. This process ensures that no attorneys become involved in the dispute and is less time-consuming.
- Minitrial: A minitrial takes more time and money than a mediation. The minitrial takes place in an informal setting and involves some type of advisor or attorney that must be paid. The disputing parties may come to an agreement or the third party advisor may offer their advice. The agreement is nonbinding and can be broken.
- Arbitration: Arbitration is the most costly and time-consuming way to resolve a dispute. Each party is represented by an attorney while witnesses and evidence are presented. Once all information is provided on the issue, the arbitrator makes a ruling which provides the final decision. The arbitrator provides the final decision on what must be done and it is a binding agreement between each of the disputing parties.
The following terms are commonly used in the industry:
- Construction management (CM) refers to form of delivery and (in the UK) management of the site.
- Real estate management (REM) is professional property advice (a continuous process, as opposed to a process).
- Corporate real estate management (CREM) is a company-focused variant.
- Management contracting (MC):
- UK: form of delivery
- US: CM at risk
- Programme management (ProgM) is concerned with management of a client’s portfolio (the programme, in this sense, is equivalent to a client’s brief) or (in the UK) managing time in a project.
- Project control (PC) is the tracking and reporting of the progress, time, cost and quality of a project. This function can be characterized as passive, whereas construction project management (CPM) is active.
- Project leader (PL): The person responsible for achieving the project’s objectives; acts as a manager "in-line".
- Project director (PD): The leader of a large project that can be broken down into sub-projects (e.g. the Channel tunnel) or the head of a PM organization
- Owner representative (OR): The representative of the owner; may be internal or external to the company
- Document Control (DC): Key function of a project manager
- Build operate transfer (BOT)[clarification needed]
- Build own operate (BOO)[clarification needed]
- Engineering procurement construction (EPC)[clarification needed]
- Private finance initiative (PFI)[clarification needed]
- General contract (GC)[clarification needed]
- Joint Venture (JV): A collaboration between two or more companies from the same or different backgrounds and/or fields to complete a common project. Joint Ventures typically have a lead contractor that deals with most of the business aspects. The lead will usually have a bigger stake in the partnership (ie. the lead will have a 65% stake while the second contractor might have 30% and a third might have 5%).
- Guaranteed maximum price (GMP): A contract-specified upper limit to the project's final price
- Multiple prime contracts (MPC)
- UK: One contractor takes responsibility for the development (package deal).
- US: A client may have five or six prime contractors.
Study and practice
Construction Management education comes in a variety of formats: formal degree programs (Two-year associate degree; four-year baccalaureate degree, masters degree, project management, operations management engineer degree, doctor of philosophy degree, postdoctoral researcher); on-the-job-training; and continuing education and professional development. Information on degree programs is available from the American Council for Construction Education (ACCE) or the Associated Schools of Construction (ASC).
According to the American Council for Construction Education (the academic accrediting body of 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, through management skills specifically related to construction, to technical knowledge of construction methods and practices. There are many schools offering Construction Management programs, including some offering a Masters degree.
Skills and abilities
- Time Management
- Decision Making
- Problem Solving
The construction industry typically includes three parties: an owner, a designer (architect or engineer) and a builder (usually known as a general contractor). There are traditionally two contracts between these parties as they work together to plan, design and construct the project. The first contract is the owner-designer contract, which involves planning, design and construction administration. The second contract is the owner-contractor contract, which involves construction. An indirect third-party relationship exists between the designer and the contractor, due to these two contracts.
An owner may also contract with a construction project management company as an advisor, creating a third contract relationship in the project. The construction manager's role is to provide construction advice to the designer, design advice to the constructor on the owner's behalf and other advice as necessary.
Design, bid, build contracts
The phrase "design, bid, build" describes the prevailing model of construction management, in which the general contractor is engaged through a tender process after designs have been completed by the architect or engineer.
Many owners – particularly government agencies – let out contracts known as design-build contracts. In this type of contract, the construction team (known as the design-builder) is responsible for taking the owner's concept and completing a detailed design before (following the owner's approval of the design) proceeding with construction. Virtual design and construction technology may be used by contractors to maintain a tight construction time.
There are three main advantages to a design-build contract. First, the construction team is motivated to work with the design team to develop a practical design. The team can find creative ways to reduce construction costs without reducing the function of the final product. The second major advantage involves the schedule. Many projects are commissioned within a tight time frame. Under a traditional contract, construction cannot begin until after the design is finished and the project has been awarded to a bidder. In a design-build contract the contractor is established at the outset, and construction activities can proceed concurrently with the design. The third major advantage is that the design-build contractor has an incentive to keep the combined design and construction costs within the owner's budget.
The major problem with design-build contracts is an inherent conflict of interest. In a standard contract the designer is responsible to the owner to review the builder's work, ensuring that the products and methods meet specifications and codes. An independent builder may pick up design flaws which might go unnoticed (or unmentioned) if the builder is also the designer. The owner may get a building that is over-designed to increase profits for the design-builder, or a building built with lesser-grade products to maximize profits. If speed is important, design and construction contracts can be awarded separately; bidding takes place on preliminary plans in a not-to-exceed contract instead of a single, firm design-build contract.
Planning and scheduling
Project-management methodology is as follows:
- Work breakdown structure
- Project network of activities
- Critical path method (CPM)
- Resource management
- Resource leveling
- Risk assessment
- Work inspection
- Change orders
- Review payments
- Materials and samples
- Shop drawings
- Three-dimensional image
Construction cost management is a fee-based service in which the construction manager (CM) is responsible exclusively to the owner, acting in the owner's interests at every stage of the project. The construction manager offers impartial advice 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 concept and project definition, yields the greatest benefit to owners. 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 select the design and construction teams and managing the design (preventing scope creep), helping the owner stay within a predetermined budget with value engineering, cost-benefit analysis and best-value comparisons. The software-application field of construction collaboration technology has been developed to apply information technology to construction management.
CM at-risk is a delivery method which entails a commitment by the construction manager to deliver the project within a Guaranteed Maximum Price (GMP). The construction manager acts as a consultant to the owner in the development and design phases (preconstruction services), and as a general contractor during construction. When a construction manager is bound to a GMP, the fundamental character of the relationship is changed. In addition to acting in the owner's interest, the construction manager must control construction costs to stay within the GMP.
CM at-risk is a global term referring to the business relationship of a construction contractor, owner and architect (or 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 (comparable to a "low-bid" contract), but with adjustments in responsibility for the CM. The advantage of a CM at-risk arrangement is budget management. Before a project's design is completed (six to eighteen months of coordination 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 project's scope. In balancing the costs, schedule, quality and scope of the project, the design may be modified instead of redesigned; if the owner decides to expand the project, adjustments can be made before pricing. To manage the budget before design is complete and construction crews mobilized, the CM conducts site management and purchases major items to efficiently manage time and cost.
