BNi and eConverge launch BNi Reference mobile construction cost app

BNi Building News and eConverge have launched BNi Reference, a new subscription service that puts BNi construction cost books on phones, tablets, and desktops nationwide. The rollout gives contractors, estimators and other industry professionals searchable access to trusted cost data starting at $14.99 per month per book.

Why it matters: - BNi Reference moves long-trusted construction cost data from printed books to a mobile, searchable format. - The launch gives professionals a portable way to review costs, methods and maintenance options in the office, on site or in meetings. - Individual cost book subscriptions start at $14.99 per month, lowering the barrier to access compared with buying printed volumes. - Each subscriber also gets free access to eConverge Community, which adds industry news, articles, educational resources and technical references.

What happened: - BNi Building News and eConverge launched BNi Reference nationwide on August 25, 2026. - The service is available through the Apple App Store and Google Play, along with desktop access. - The initial release includes six BNi cost books: BNi Electrical, BNi Facilities Manager’s, BNi General Construction, BNi Mechanical-Electrical, BNi Public Works and BNi Remodeling. - The product is positioned as a subscription-based alternative to printed construction cost books.

The details: - BNi Reference is designed for contractors, estimators, facility managers, architects, engineers, consultants, educators, manufacturers, distributors and owners. - The platform is built to support research on products, construction methods, building systems, maintenance alternatives and budget development. - eConverge Community includes thousands of construction articles, industry news, educational resources, manufacturer and supplier information, product announcements, technical references, videos and professional insights. - BNi Building News has provided construction cost data, technical references, publications and industry information since 1946. - BNi Reference is described as powered by eConverge. - BNi Building News was founded in 1946. - The company has supported construction professionals for 80 years with trusted information.

Between the lines: - The launch reflects a broader shift in construction reference tools toward digital access and searchable workflows. - Putting cost books on mobile devices may matter most for field teams and decision-makers who need fast answers outside the office. - The free community access suggests the subscription is meant to be more than a digital book replacement and could become a broader professional information hub. - Bill Mahoney said BNi has worked since 1946 to be a trusted source and that BNi Reference carries that commitment forward. - Michael Brown said the new format puts trusted construction information “in your pocket” and called the launch only the beginning.

What's next: - BNi Reference will likely expand beyond the initial six cost books as the platform develops. - BNi and eConverge are directing users to the BNi Reference overview for a closer look at the product. - The service is available now for subscribers through the major app stores.

The bottom line: - BNi Reference turns a legacy construction cost library into a mobile subscription product aimed at faster, more flexible decision-making across the industry.
