Build Project Case Study

Rooftop Terrace Renovation

When a Battery Park City homeowner and successful hedge fund manager decided to renovate his 1,130-square foot rooftop space, he approached Bolster, as well as his building's in-house contractor.

His building's contractor, claimed it could deliver the project 2.17 times faster than Bolster Contractor Aaron Borenstein, while using only 17% of the resources. The homeowner was curious as to why there was such a dramatic difference between the two, and decided to educate himself about how the business of bidding works. 

He found that from the start, Bolster followed a thorough and data-driven process in order to create its bid, beginning by visiting his rooftop to estimate a price range from which to plan. With the help of the Bolster App, which uses an algorithm to deliver a statistically accurate projection of project costs, Bolster Professionals were then able to provide the minimum and maximum possible figures for his renovation.
