Public project owners use additive, deductive or alternate bid items for a good reason. The practice gives owners flexibility to arrive at a scope of work that fits their project budget and provides them with the most project for that budget. The use of alternate bid items also complicates the process, however. It is a common source of disputes.
Many bid protests involve the treatment of alternate bid items in the evaluation and comparison of bids. Some critics contend the practice enables public project owners to manipulate the sealed bidding process, customizing a scope of work which will result in a favored bidder being the low bidder. ...

In an exclusive interview with ConstructionPro Week (CPW), a spokesperson for the recently formed American High-Performance Buildings Coalition (AHPBC) applauded the U.S. Green Building Council (USGBC) for “raising the profile of sustainable construction through its LEED [Leadership in Energy and Environmental Design] program” but did raise some concerns. The new AHPBC consists of 27 member groups involved in manufacturing, material science, and building performance and whose collective stated mission is to promote and support the development of sustainable building standards that are “based on consensus and scientific performance data.”
During the interview, although AHPBC spokesperson Justin Koscher credited USGBC for bolstering the industry’s sustainable-construction profile, he added that “all green building rating systems have room for improvement, and [AHPBC] will offer its experience and expertise as systems evolve. There are concerns among coalition members with the process used by USGBC to develop and update LEED. USGBC itself has said that it does not care to use the ANSI [American National Standards Institute] process. This is unfortunate given that the ANSI process is transparent, open, and constructive, which yields the highest-quality results.” ... Read more.

A new augmented reality modeling system allows a contractor to determine whether a project is on, ahead, or behind schedule, leading to cost savings and a reduction in project delivery time, according to Virginia Polytechnic Institute and State University. Mani Golparvar-Fard, an assistant professor of civil and environmental engineering at Virginia Tech, developed the system, called 4 Dimensional Augmented Reality (D4AR), which the institution believes provides new possibilities for the construction industry, including evidence for dispute resolution, safety inspection measures, progress evaluation and analysis, and faster, more accurate as-built versus as-planned evaluation.
The system automatically analyzes physical progress on large-scale construction projects, the university stated. “Without the need for a Global Positioning System or any other location tracking technology, the modeling system ... is able to geo-spatially store digital pictures of a building in 4D (3D plus time) and integrates the photos with building information models (BIM) during any and all phases of construction.” ...
