Construction Terminology Glossary

Definitions of Construction Terms

To help you better understand the construction process, we’ve put together a glossary of construction terms that we may use at Jos Schmitt Construction. *Please note that construction terms and definitions may vary based on each company and services provided.

Adaptive Reuse

The conversion of an existing structure for a purpose other than which it was originally designed, often preserving the building’s historic elements while adapting it for modern use.

Addendum (Addenda)

This is a formally written document that modifies the original contract documents. It acts as an extension or amendment to the initial agreement.

Alternate Bid

An alternate bid lets you propose changing materials or methods for specific parts of the project, affecting the final cost.

Architects Supplemental Information (ASI)

Think of this as an architect’s “post-it note” on the blueprints. It clarifies something, fixes a mistake, or makes minor adjustments to the plans. It’s a way to fine-tune things without completely redrawing everything.

As-Built Drawings

Updated drawings that reflect any changes made during the construction process, providing an accurate representation of the completed project.

Assignable Square Footage (ASF)

Assignable Square Footage (ASF) refers to the functional area within a commercial space, excluding areas such as closets and hallways. It represents the square footage allocated to the primary activities occurring within the space.

Bid

A formal offer, usually in response to a request for proposal (RFP) or invitation to bid, outlining the cost of performing a construction project.

Bidding Documents

These are the official instructions for construction companies, telling them what to build, how much it should cost, and the rules they need to follow.

Blueprint

Detailed architectural and engineering drawings that serve as a guide for construction, including floor plans, elevations, and specifications.

Building Envelope

The building envelope refers to all the structural and non-structural elements that separate the conditioned interior environment of a building from the unconditioned exterior environment.

Building Manager

This is the building’s head housekeeper, making sure everything runs smoothly and fixing any problems that pop up. They’re like the captain of the ship, keeping things afloat.

Campus Master Plan

Imagine a blueprint for the entire campus, showing where buildings will go, how they’ll connect, and how the space will be used. It’s the long-term vision for the campus’s growth and development.

Change Order

A written order that modifies the original construction contract, detailing changes in the work, specifications, or other project aspects.

Cohesive Construction

An approach emphasizing collaboration and integration among project team members to achieve a seamless and efficient construction process.

Concrete Mix Design

The process of proportioning ingredients to create a concrete mix with specific strength, durability, and workability characteristics.

Constructability Review

Before you start building, it’s wise to have someone double-check the blueprints. A constructability review is like hiring an expert to examine the plans and make sure everything is accurate, feasible, and well-detailed. This can save time and money by avoiding construction mistakes later on.

Construction Documents (CD Phase)

Think of these as the blueprints for building your dream house. Construction documents, also known as CDs, are detailed plans and instructions that show exactly how to construct the physical spaces of a building. These include drawings, specifications (lists of materials and methods), and any add-ons (changes made during the planning process).
