They address different aspects of the project, including as general circumstances, scope of work, material quality, and craftsmanship requirements. The drawings, together with the project specifications, specify the project in detail and explicitly outline how it is to be built. The project manager should review them with the owner and other stakeholders to ensure that all requirements are met and any changes can be agreed upon.
The project manager should also oversee the preparation of these documents. They can be prepared by a licensed architect or engineer or they can be done by a staff member who is not an accredited professional. It is important for the project manager to understand which qualifications each person holding a role on the project has so that they can be assigned appropriate duties. For example, someone without architectural training may be able to prepare some drawings but not others. There are also sometimes sub-contractors that will be used for specific tasks such as building foundations or interior design. It is important that you as the project manager have clear understanding of what these sub-contractors' roles are so that they do not overlap with others.
In addition to the standard specifications, there are also specialty specifications required for certain types of projects. These include health care facilities, schools, libraries, and child care centers, just to name a few. The project manager should work with the owner and other stakeholders to make sure that these special requirements are taken into account when planning the project.
Specifications will define the materials, standards, processes, and so on that will be needed to complete the task. Construction drawings give a graphical depiction of the component arrangement, details, proportions, and so on. They can also include other ancillary information such as cut lists for fabrication or assembly instructions.
Construction drawings are used by architects, engineers, contractors, and others involved in the design and construction of buildings to visualize and document how components should be arranged on a job site. They provide detail-level information about materials, techniques, and equipment needed to build the project. The construction drawings should be reviewed with the owner and/or contractor to ensure they understand their requirements before starting work. Revision may be necessary if changes are made to the plan view during development or if additional features need to be added.
After all relevant approvals have been received, the construction documents can be issued to contract administrators for distribution to subcontractors.
Subcontractors will review the list of approved trades provided by the owner or architect and only include those companies that will actually be working on the project. They will then request the required drawings from these potential vendors. Some trade professionals may choose to obtain detailed drawings but most only require a rough idea of what will be done on the project.
The specification specifies the project's aim, performance, and construction. It can be used to refer to the quality and standards that should be followed. A specification may help with project price by include not only materials and goods, but also performance and craftsmanship. The building owner or contractor will be able to compare different bids by looking at the specifications included in the tender document.
For example, a builder might quote to construct a house according to plans supplied by the homeowner. If no plans are provided, then the builder is free to construct his own version of the house and submit it as proof of ability. But if he does so, he must follow the same rules as far as design and material selection are concerned. He cannot pick and choose which aspects of the plan to implement because this would mean that good workmanship was not guaranteed.
The specification should be made available to bidders before they put in a bid. This gives them time to study the market for what they are offering and decide whether it is within their budget. They can also see what other companies are offering and make an informed decision about how much they want to charge for their work. If they find out after they have signed a contract that something important was not mentioned in the specification, they can back out of the deal without losing money. However, if they say yes when asked, they would be expected to go ahead and complete the project.
Specification's purpose is to specify the quality of various materials necessary for building activity. It helps the department, engineers, architects, and contractors to specify, purchase, and inspect the quality of materials in accordance with requirements. To clarify the drawings, specifications are necessary. They can be either written or oral. Written specifications are more accurate but also more time-consuming to produce.
In construction projects, there are usually several parties involved: contractor, sub-contractors, suppliers. It is important that they all understand their roles and responsibilities so that there are no misunderstandings once the project starts. For example, the contractor should know exactly what kind of materials he is going to use and how they will be installed by a subcontractor. The same thing goes for suppliers - they should know who their customers are and provide only the required products/services.
Written specifications can be created by any one of these parties. However, it is best if they are created by someone with expertise in creating technical documents - such as a structural engineer or an architect. These people can be part of a single firm or different firms working together. If different firms work on separate documents then they should coordinate with each other before they submit their documents for approval. For example, the structural engineer may need to review the drawings submitted by the architect and make any changes that may be necessary. There should be no surprises when the contracts are signed - everyone should know what they are getting into.
Building standards, commonly known as specs, specify the effort and craftsmanship required to execute a construction project. The two main types of building standards are code-mandated and consensus-based. Code-mandated standards are those set forth by governing bodies such as the International Building Code or the National Electrical Code. Consensus-based standards are developed through negotiations between builders and architects/contractors.
Code-mandated standards include requirements for safety, health, energy efficiency, and other factors relevant to the execution of a construction project. These standards are presented in the form of codes that address various aspects of building construction including materials, techniques, and procedures. For example, the International Building Code is a consensus standard published by the International Committee on Building Standards (ICBS). It is widely regarded as the primary guideline for new construction and major renovations across the world. The ICBS develops its guidelines through discussions with representatives from all sectors of the building industry including owners, architects, engineers, contractors, manufacturers, and users of buildings. As a result, the Code contains detailed requirements for everything from hand tools to high-rise structures.
Consensus-based standards are also referred to as general practices.
