What You Need to Know About the Design Process and Construction Documents

By The PHD Team
Updated May 10, 2024

Building a house is a very complex and systematized process. For a house to be built from the ground up, the Architect must set up a system on how to run the project from the design phase to the construction phase up to the final stage. One of the most important elements that make a project run smoothly is the construction documents which serve as a guide for everyone involved in the project – including the client. 

The construction documents have two primary functions: the first to submit a construction permit application to the city or other local authority, and the second is to start the construction.  Preliminary Sets includes phases Rough Draft, First Drafts, and Pre-finals.  Pre-finals are used to obtain permits and the Final Set is used for the construction.

Every time we begin a new project, we always spend the time thoroughly explaining each page to the client so that they are aware of every stage of the procedure and what each drawing represents. So, in this blog, we will go through each page of a typical set of construction documents to give you a general understanding of what they are and why it is crucial to understand them.

A drawing set adheres to a similar format regardless of the kind of building or design to make it easier for contractors, permit officers, and other construction industry professionals to manage the information for each design.

We have clients of all different disciplines and backgrounds, for this reason we offer packaged design sets (our most common sets group together) or “a la carte” options. One thing we noticed very quickly is that in Louisiana everyone knows someone. Meaning, almost every client we have worked with has an uncle, aunt, cousin, brother etc. in one of the trades required to build a house! So, we offer “a la carte” only pay for what you need above our base package.

Under each sheet listed below, we will list which package they are included in. Please reach out to us for a list of our packages and pricing.

Cover Sheet

(Included in all Packages)

architectural construction plans displaying a 3d rendering of a residential property with detailed annotations and measurements, alongside official stamps and project information.

The Cover Sheet includes a wealth of information that serves to set the project’s direction. It contains information about the property, a list of the sheets included, and Stock 3D views of the project.  General notes about the construction of the project and a code matrix outlining all the regulations that apply are listed. The zoning used and the type of building can also be found on this page including general information about the architect or architecture firm, engineers, consultants, and other professionals involved. 

ARCH-100 – Site Plan

(Included in Architect and Complete Experience)

Site plan page of blueprint plans

The site plan illustrates how the building is situated throughout the entire property. On this page, you will see the plan view of the building and its exact position in your lot with the required setbacks applied.  Elements such as the curvature of the driveway and direction of the sidewalks are included in the site plan to give the client an overall understanding of accessing the homes’ points of entry. Finally, predetermined easements by utility companies will also be notated.  Depending on the scope of the project, the site plan sheet may also include a landscaping plan or future projects (shops, pools, etc.) associated with the site. 

DEMO-100 – Existing/Demo Plan

two architectural floor plan drawings side by side, featuring detailed room layouts and measurements, each with a certification stamp on the lower right.

This is our “existing” and “demo” plans. These sheets are produced by our team using the latest in 3d scan and satellite technology. Once we receive the scans, we basically model your existing home or building into our 3D software (Revit). This gives us a great basis with accuracy and allows us to start our design work and options. From here once we solidify a design, we work on the demo plan, showing your contractor exactly what they will need to remove before construction can begin. 

ARCH-200 – Floor Plans & Schedules

(Included in All Packages)

Floor plan page of blueprint plans

The floor plan sheets are considered the core of the drawing set. A construction document set can have multiple floor plan pages depending on how large the building is or how many floors there are in the design. Fixed furniture, cabinetry, and fixtures are present in the floor plans.  Detailed information on this sheet includes the room finish schedule, door and window schedules as well as trim and floor notes.

ARCH 225 – Framing Details

(Included in all Packages – For custom details additional fees applicable)

blueprints and detailed architectural drawings of various building components, including structural joints and floor plans, accompanied by technical specifications and notes.

The framing details show detailed views of the roof and wall assemblies that will be used to construct the building. This includes the material type, the size, spacing, code details and some detailed specifications that the contractor should know. These details are very important to understand how the structural elements are being placed to form the skeleton of the building.  

ARCH-300 – Wall Details & Roof Plan

(Included in all Packages)

In buildings where certain interior or exterior walls vary in construction or material type, detailed drawings are provided and are illustrated in a separate sheet. Certain types of details such as advanced framing or zero energy details may result in additional fees.

The roof plan is a two-dimensional design that shows your roof from above. It contains annotations that provide information about the roof’s pitch, elevation, ridges, and slopes.  It will call out exhaust and chimney locations as well as roof types.  If this is an addition, it will specify which is existing and which is new construction.

ARCH-400 – Elevations & Building Sections

(Included in all Packages)

technical architectural drawing of a residential house, displaying detailed elevations from multiple sides with dimensions, materials, and construction notations specified.

The elevation sheets are the 2D exterior faces of the building’s façade. It includes four faces namely, front, rear, left, and right-side elevation.  The height of the building as well as the materials to be applied or conserved is indicated in the drawings with keynotes specifying significant external construction information. 

If the house is a 2-story, it will include building sections if necessary.  A section drawing displays a vertical slice transecting the building, usually along a principal axis.  Sections are utilized to clarify the inner architecture of a part that cannot be properly depicted by concealed lines in exterior views.  

DETAIL-500 Sheets

technical architectural drawing featuring multiple schematics for construction details, including dimensions, material specifications, and sections. the plan is stamped with approval from a design consultancy.

This closet detail sheet gives you and the builder a visual idea of what “1R1S” or “4S” mean. These drawings give everyone standards of how the closet/trim work is to be built and detailed out. Use these drawings to reference the floorplan for  the “short terms” and see the full visual and dimensions of what we are specifying in the closets. 

architectural design layout for a kitchen featuring multiple elevations and detailed dimensions. includes rendered images showcasing different views of the cabinetry and workspace. the plan is professionally marked with logos and annotations.

To accurately grasp the architect’s meaning and properly interpret the building’s requirements, it is helpful for both clients and builders to be able to read and understand construction documentation. Drawings are crucial since they are utilized to communicate project technical data in a consistent way.  We use keynotes to ensure every detail, such as closet/rods, microwave location, so on are included to help ease the relationships between the subcontractors in the field and the contractor/client.  

Once we’ve completed the Preliminary Construction Documents to get the permit, we’ll have to wait for the competent authorities to process them. As the Preliminary Set is being processed, we complete the Final Construction set so that we can go straight to the contractor once the building permit is issued.

With our diverse background of experience and staff, we also offer a list of other “A La Carte” options for you to choose from. Make sure to check the proposal page for all kinds of other sheets we offer! We can be as full service as a client needs/requires.
