Every construction project falls into one of two categories: horizontal vs vertical construction. If you’ve ever worked on an infrastructure project like roads, bridges, or railways, you’ve dealt with horizontal construction. On the other hand, if you’ve been involved in constructing high-rise buildings, apartments, or office towers, you’ve worked with vertical construction.
But Which one is right for your project?
In this guide, we’ll break down the key differences, similarities, and use cases of both construction types. We’ll also explore how BIM (Building Information Modeling) is transforming both horizontal and vertical construction projects.
So, if you’re an AEC professional looking to make an informed decision, let’s dive in!
What Is Horizontal Construction?
Horizontal construction refers to infrastructure projects that expand outward across large areas rather than growing vertically. These projects are typically associated with transportation, land development, and large-scale civil engineering works. They serve as the backbone of a nation’s economy by enabling connectivity and supporting industries like logistics, trade, and public services.
