Building plans are a set of drawings or any graphical representation that shows how a building would look during and after construction. It consists of site plans, floor plans, elevations, and even electrical and plumbing layouts. Builders and contractors use these plans as construction guides and to also estimate construction costs. Through this, project managers know that having a building plan can save them time and money.
Another way for contractors and project builders to save time and money is by using AI estimating software. This software uses powerful artificial intelligence algorithms that help speed up the design process, de-risking the construction and improving the estimations that will help make every project a success.
By having a building plan coupled with the power of AI estimating software, you can have maximum productivity, improved safety, and better resource procurement.

What are multi-unit buildings?
A multi-unit building is a single residential property that contains more than one housing unit, like an apartment complex. They are also usually characterized by having connected or shared walls and can be developed at different heights and densities.
It is an excellent option for close-knit families who wish to live together but are in their own, separate units. It’s also beneficial for investors and business owners who want to maximize their ROIs by either renting out or selling a unit.
For example, acquiring multi-family housing, like a 100-unit apartment building, will be a lot easier than purchasing 100 single-family homes. Owning a 20 unit apartment will also produce more monthly income and will have more flexibility in outsourcing property management services.
Builders and contractors who develop these kinds of housing usually face a lot of construction hurdles. Multi-unit housings are equipped with all of the features and amenities of a typical home. The difference is that it has a shared pillar, roof, water. electricity utility, and a lot more. Hence, building plans are more than necessary for both contractors and clients alike.
