Otheruses are essential in large construction projects, such as this skyscraper]] , Canada. A crane is readied to lower a barge into the water. This barge will be placed under any cutting work on the bridge to lessen the environmental impact. Note the concrete barricades and snow fencing in place to protect the public and workers.]]In project architecture and civil engineering, construction is the building or assembly of any infrastructure. Although this may be thought of as a single activity, in fact construction is a feat of multitasking. Normally the job is managed by the construction manager, supervised by the project manager, design engineer or project architect. While these people work in offices and make the most money, every construction project requires a large number of laborers to complete the physical task of construction. For the successful execution (management)execution of a project effective planning is often essential. Those involved with the design and execution of the infrastructure in question must consider the environmental impact of the job, the successful scheduling, Budgetbudgeting, Construction site safetysite safety, inconvenience to the public caused by construction delays, tenderpreparing tender documents... The list goes on and on.


Construction - In general, there are three types of construction: (1) building, (2) heavy/highway, and (3) industrial. Each type of construction requires a unique team to plan, design, construct, and maintain the project.

Building construction - Building construction is the process of adding structure to real property. The vast majority of building construction projects are small renovations, such as addition of a room, or renovation of a bathroom. Often, the owner of the property acts as laborer, paymaster, and design team for the entire project. However, all building construction projects include some elements in common - design, financial, and legal considerations. Many projects of varying sizes reach undesirable end results, such as structural collapse, cost overruns, and/or litigation, as a result of insufficient planning. For this reason, those with experience in the field make detailed plans and maintain careful oversight during the project to ensure a good outcome.For projects of large size and/or unusual type, the owner will likely establish a team of workers and advisors to create an overall plan. This ensures that the project will proceed in an orderly way to a desirable end. While no set list would establish what is needed or advisable for a particular project, frequently used advisors include mortgage bankers, accountants, lawyers, insurance brokers, architects, and engineers. While their roles overlap, each area of expertise addresses an element of what will be affected by the building construction project.

Heavy/Highway construction - Heavy/Highway construction is the process of adding !Infrastructure#Urban_planning_ usage"infrastructure" to our built environment. Owners of these projects are usually government agencies, either at the national or local level. As in building construction, heavy/highway construction has design, financial, and legal considerations, however these projects are not usually undertaken for-profit, but to service the public interest. In addition, in many countries public agencies must adhere to many legal requirements that require the project to undergo a public bid process. As in building construction, the owner will assemble a team to create an overall plan to ensure that the goals of the project are met.

Industrial construction - Industrial construction, though a relatively small part of the entire construction industry, is a very important component. Owner of these projects are usually large, for-profit, industrial corporations. These corporations are can found in such industries as medicine, petroleum, chemical, power generation, manufacturing, etc. Processes in the industries require highly specialized expertise in planning, design, and construction. As in building and heavy/highway construction, this construction requires a team of individuals to ensure project success.

Design team - In the modern industrialized world, construction usually involves the translation of paper or computer based designs into reality. A formal design team may be assembled to plan the physical proceedings, and to integrate those proceedings with the other parts. The design usually consists of drawings and specifications, usually prepared by a design team including architects, civil engineers, cost engineers (or quantity surveyors), mechanical engineers, electrical engineers, and structural engineers. The design team is most commonly employed by (i.e. in contract with) the property owner. Under this system, once the design is completed by the design team, a number of construction companies or construction management companies may then be asked to make a bid for the work, either based directly on the design, or on the basis of drawings and a bill of quantities provided by a surveyor. Following evaluation of bids, the owner will typically award a contract to the lowest responsible bidder.The modern trend in design is toward integration of previously separated specialties, especially among large firms. In the past, architects, engineers, developers, construction managers, and general contractors were more likely to be entirely separate companies, even in the larger firms. Presently, a firm that is nominally an "architecture" or "construction management" firm is likely to have experts from all related fields as employees, or to have an associated company that provides each necessary skill. Thus, each such firm may offer itself as "one-stop shopping" for a construction project, from beginning to end.Several project structures can assist the owner in this integration, including design-build, partnering, and construction management. In general, each of these project structures allows the owner to integrate the services of architects, engineers, and constructors throughout design and construction. In response, many companies are growing beyond traditional offerings of design or construction services alone, and are placing more emphasis on establishing relationships with other necessary participants through the design-build process.

Financial advisors - Many construction projects suffer from preventable financial problems. Underbids ask for too little money to complete the project. Cash flow problems exist when the present amount of funding cannot cover the current costs for labor and materials, and because they are a matter of having sufficient funds at a specific time, can arise even when the overall total is enough. Fraud is a problem in many fields, but is notoriously prevalent in the construction field. Financial planning for the project is intended to ensure that a solid plan, with adequate safeguards and contingency plans, is in place before the project is started, and is required to ensure that the plan is properly executed over the life of the project.Mortgage bankers, accountants, and cost engineers are likely participants in creating an overall plan for the financial management of the building construction project. The presence of the mortgage banker is highly likely even in relatively small projects, since the owner's equity in the property is the most obvious source of funding for a building project. Accountants act to study the expected monetary flow over the life of the project, and to monitor the payouts throughout the process. Cost engineers apply expertise to relate the work and materials involved to a proper valuation.Large projects can involve highly complex financial plans. As portions of a project are completed, they may be sold, supplanting one lender or owner for another, while the logistical requirements of having the right trades and materials available for each stage of the building construction project carries forward.

Legal considerations - A construction project must fit into the legal framework governing the property. These include governmental regulations on the use of property, and obligations that are created in the process of construction.The project must adhere to zoning and building code requirements. Constructing a project that fails to adhere to codes will not benefit the owner. Some legal requirements come from malum in se considerations, or the desire to prevent things that are indisputably bad - bridge collapses or explosions. Other legal requirements come from malum prohibitum considerations, or things that are a matter of custom or expectation, such as isolating businesses to a business district and residences to a residential district. An attorney may seek changes or exemptions in the law governing the land where the building will be built, either by arguing that a rule is inapplicable (the bridge design won't collapse), or that the custom is no longer needed (acceptance of live-work spaces has grown in the community).Also, a construction project is a complex net of contracts and other legal obligations, each of which must be carefully considered. A contract is the exchange of a set of obligations between two or more parties, but it is not so simple a matter as trying to get the other side to agree to as much as possible in exchange for as little as possible. The time element in construction means that a delay costs money, and in cases of bottlenecks, the delay can be extremely expensive. Thus, the contracts must be designed to ensure that each side is capable of performing the obligations set out. Contracts that set out clear expectations and clear paths to accomplishing those expectations are far more likely to result in the project flowing smoothly, whereas poorly drafted contracts lead to confusion and collapse.Legal advisors in the beginning of a construction project seek to identify ambiguities and other potential sources of trouble in the contract structure, and to present options for preventing problems. Throughout the process of the project, they work to avoid and resolve conflicts that arise. In each case, the lawyer facilitates an exchange of obligations that matches the reality of the project.

Interaction of expertise - Design, finance, and legal aspects overlap and interrelate. The design must be not only structurally sound and appropriate for the use and location, but must also be financially possible to build, and legal to use. The financial structure must accommodate the need for building the design provided, and must pay amounts that are legally owed. The legal structure must integrate the design into the surrounding legal framework, and enforces the financial consequences of the construction process.
