Other Resources

On every job, there is an initial planning phase known in the construction industry as “preconstruction”. This phase of the project serves to lay out the entire scope and timeline of a project for the construction team and the client.

A term that refers to applications, services, or resources made available to users on demand via the Internet from a cloud computing provider’s servers.

A “takeoff” is the act of measuring construction plans to determine the material quantities needed for a job.

An “estimate” comes together when you take the material quantities from your takeoff and add in pricing as well as other costs such as labor, overhead, and profit margin to finalize your bid.

Items refer to individual materials with predefined measurement details (such as height, width, depth, etc.).

Assemblies refer to a collection of items, grouped together for a common purpose

    • STACK Invite – Invite can be used to distribute projects and their corresponding plan sheets for the purpose of allowing these 3rd parties to perform their own markups and measurements.
    • STACK Share – Sharing can be used to send read-only projects for the purpose of distributing already completed work for review or reference.
    • Markup Tools – Add markups such as text, highlights, clouds, plan legends, callouts, and more to your documents to provide clarity and communicate project needs.

An API, which stands for Application Programming Interface, is a set of requirements that govern how one application can communicate and interact with another. In other words, an API is a messenger that delivers your request to the provider that you’re requesting it from and then delivers the response back to you.
