What is basis of design

The Basis of Design (BoD) document records the thought processes and assumptions behind major design decisions being made to meet the Owner’s Project Requirements (OPR). … Without this information, future teams have to guess at the designer’s line of reasoning followed during the design process.

What is basis of design in engineering?

Basis-of-Design Product: Where Specifications name a product, or refer to a product indicated on Drawings, and include a list of manufacturers, provide the specified or indicated product or a comparable product by one of the other named manufacturers.

What is basis of design in architecture?

The Basis of Design (BOD) documents the principles, assumptions, rationale, criteria, and considerations used for calculations and decisions required during design. … It includes catalog cuts and manufacturers information used to set the minimum levels of quality or performance set by the design.

What is a basis of design narrative?

The Basis of Design Narrative is the Design Team’s implementation of the Program of Requirements (POR). It presents the basic rationale and assumptions, criteria, logic, and considerations developed in evaluation of MEPFP systems design.

What is a design basis memorandum?

The design basis memorandum (DBM) should be one of the first documents prepared by the engineer during the definition phase, as it sets down the basic design parameters for the project going forward and includes: A description of the project.

What is design intent?

Design intent is a method used in computer-aided design that defines relationships between objects, so that a change to one propagates automatically to others.

What is included in design development documents?

The design documents should clearly identify the developed civil, architectural, structural, mechanical, electrical, plumbing and fire protection design solutions. All major features and components of the design solution should be documents and included in the up- dated cost estimate and compound with AFC.

What is the primary purpose in establishing design criteria in design?

Design criteria provide specific guidance on the big questions that are at the heart of the problem and that require a solution.

What is the basis of specification?

A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard.

What is owner's project requirements?

Owner’s Project Requirements (OPR) is a written document that details the functional requirements of a project and the expectations of how it will be used and operated.

What is beneficial occupancy date?

Beneficial Occupancy Date (BOD), CC850 – BOD is the date the customer can expect to receive useful occupancy of the facility or construction work. … For military projects, this is the date the client should sign the initial DD form, 1354, Transfer of Real Property.

What are the steps in the design process?

1. Define the Problem. You can’t find a solution until you have a clear idea of what the problem is.
2. Collect Information. Collect sketches, take photographs and gather data to start giving you inspiration.
3. Brainstorm and Analyze Ideas. …
4. Develop Solutions. …
5. Gather Feedback. …
6. Improve.

Why is design intent important?

It allows you to modify your design. They can help reduce material usage, production time, and costs when it comes to prototyping and development. Engineers can run the product design through simulation software to see how well it will hold up in various conditions, which can often identify design flaws.

What is process design criteria?

What the organization needs and expects of the process to meet customer requirements.

What is primary and secondary in design?

Primary sources refer to information collected firsthand from such sources as historical documents, literary texts, artistic works, experiments, surveys, and interviews. … Thus, an experiment that is described by someone other than the researcher(s) would be considered a secondary source.

What are examples of design criteria?

The criteria are are the requirements that must be met. A design is only successful if all the criteria are met. For example, if we were designing a skateboard, three criteria might be that the skateboard: Will roll.

What are the three design phases?

The Three Phases of Design Thinking: Immersion, Ideation and Prototyping.

What are the design phases of a project?

The 5 phases of a design project are Schematic Design, Design Development, Construction Documents, Bidding, and Construction Administration, according to the American Institute of Architects (AIA).

What is a detailed design?

Detailed design is the phase where the design is refined and plans, specifications and estimates are created. Detailed design will include outputs such as 2D and 3D models, P & ID’s, cost build up estimates, procurement plans etc. This phase is where the full cost of the project is identified.

How do you write a design specification?

1. Full project overview.
2. Main needs and goals.
3. Target audience.
4. Functional requirements and desired set of features.
5. Aesthetic aspects.
6. Non-functional details.
7. Recommendation and prohibitions.
8. Questions.

What are the four types of specifications?

Deciding among the four types of specifications—descriptive, performance, reference standard, and proprietary—and choosing how the specification is going to be written is only the first of many design decisions engineers make when starting to edit what will become a project specification, especially when specifying …

What is the difference between standards and specifications?

Standards provide the “how to” of executing codes. Specifications, unlike codes or standards, outline the requirements of a specific company or product. Regulations, which can incorporate codes and standards, are mandated by a government body and required, by law, to be complied with.

What are building commissioning services?

What is building commissioning? Commissioning (Cx) is a process that checks and documents the design, installation and, testing of a building’s systems according to the requirements of the owner. It includes training of the owner’s facilities staff in order to understand and operate the building systems efficiently.

What is the difference between substantial completion and beneficial occupancy?

The terms “substantial completion” and “beneficial occupancy” are both often used interchangeably to indicate the same thing: the time or date when a construction site becomes useable for its intended purpose. The beneficial occupancy date (BOD) serves as the cutoff date for assessing Liquidated Damages.

What is the difference between substantial completion and final completion?

Construction projects typically involve two different stages of completion – Substantial Completion and Final Completion. Any work that remains to be completed after the project has reached Substantial Completion is generally referred to as punch list work and its completion usually constitutes Final Completion.
