Construction claims and changes are the bane of all construction projects. For any number of reasons, scope changes, design conflicts, changed conditions, severe weather, late submittals or late approvals, and potential change orders can be a daily occurrence on complex projects, and sometimes lead to claims.
Successful recovery for valid claims begins with a proper change management program, starting with identification.Read more.
The five-year Panama Canal Expansion project was officially inaugurated on June 26, 2016. The $5.25 billion project started construction in 2007, including a new set of locks on the Atlantic and Pacific sides of the water way and excavation of more than 150 million cubic meters of material, creating a second shipping lane and doubling the cargo capacity of the water way.

The Mechanical Contractors Association of America (MCAA) has published over the years a series of factors that affect labor productivity resulting from various situational job conditions, such as stacking of trades, weather, overtime and learning curve. The factors have frequently been used by contractors to support loss of productivity (LOP) claims on projects resulting from delays, impacts and acceleration. In response to recent court rejections of use of the MCAA factors to calculate LOP damages, Prof. William Ibbs and Dr. Xiaodan Sun conducted a study to learn why and make suggestions for improvement.
This is an excellent paper and is very informative. Proposed Improvements to the MCAA Method for Quantifying Construction Loss of Productivity documents the history of the MCAA model, it identifies mistakes in its application, and it compares the MCAA model with other LOP studies and previous case decisions. The study found that since 2001, only two of nine cases where MCAA factors were used were successful, reversing a trend of five out of five prior to 2000. Read more.
Here's a 4D building information model (BIM) of the planned new stadium for the LA Rams football team. A 4D model is one that ties objects in a 3D BIM model to activities in a CPM schedule (the 4th "D"). As the schedule is "played" on a computer display, each object in the model appears when it is encountered in the schedule like a time-lapse video. This 4D model, produced by the Conco Companies, a concrete design, construction and formwork supplier, is a good example how 4D works. Read more.
Pre-bid site visits are conducted to familiarize potential bidders with the physical conditions affecting the work. Project owners host these events to encourage tighter, more competitive bidding. Questions are asked, answers delivered. Owners frequently publish and distribute these Q & A’s to assure a level playing field. Read more...
The New NY Bridge is making progress towards replacing the 60-year old Tappan Zee across the Hudson River. Among other things, the heavy traffic, narrow lanes and lack of emergency shoulders has contributed to the bridge experiencing twice the average accident rate per mile as the rest of the NY Thruway system.

This past May the Construction Claims Advisor summarized a Washington Court of Appeals case against an engineer for faulty design and a contractor for faulty construction. Although no damage, or economic loss occurred, the building was subject to failure from seismic activity, and thus posed a safety risk. The Home Owner's Association successfully sued to recover all costs for the necessary repairs. Read more.
In last week's issue I penned an article about schedules, trying to make the point that there are schedules that may not conform to best practices but still serve the purpose of helping a contractor to effectively plan and manage a project. While some people might call non-conforming schedules "bad," I would prefer to consider them as useful but still have room for improvement. AACE President and Navigant Consulting Managing Director John Livengood posted a comment... Read more.
