Where is the critical path? This is one of the questions most often asked concerning schedule analysis. For some types of projects it is easy to anticipate where the critical path should be; for instance in high-rise building construction, the critical path is most likely to be: excavation, foundation, structure, weather enclosure (building envelope), MEP, finish activities.
The U.S. faces significant and diverse economic risks from climate change. The signature effects of human-induced climate change—rising seas, increased damage from storm surge, more frequent bouts of extreme heat—all have specific, measurable impacts on our nation’s current assets and ongoing economic activity.
Design professionals can play an important role in properly setting the course for the construction project, especially in minimizing the likelihood of claims and disputes. For example, not only can the architect serve as the master builder, but also as the master of dispute prevention and resolution.
We have never met an Owner who was happy to hear, “We need a change order.” What we’ve learned over the years is that even though change orders are facts of life in construction, there are strategies to help you avoid them.changeorders-graphic
Change orders (CO) fall into two categories – owner driven and non-owner driven. Both can be mitigated.
Owner driven change orders happen when Owners change their minds, adding a window here or changing the carpet there. We’ve even seen buildings moved and floors added mid-project, which leads us to the first CO avoidance strategy.
The primary goal in construction recordkeeping is to manage crucial information to facilitate decision-making. A secondary goal is to document key aspects of the project to provide an audit trail or comply with legal or regulatory documentation requirements. Frequently project participants lose sight of these two important goals; and resort to “wall-papering” the project office with reams of useless documents.

Process Plant profitability depends in large part on operational continuity or up-time. MDC Systems® has recently become aware of a developing technology to detect and then prevent unplanned shutdowns due to up-set operating parameters in process plants. This capability results from the real time collection and analysis of all reportable operating data…“BIG DATA.”
Process Plants typically produce more data than can be efficiently collected and reviewed by the operators. A plant with 320 tags (equipment items with associated data collection points such as pressure, temperature, flow etc), recording at 5 second intervals, will produce 5 million data readings per day. That is a billion data points over six months. Buried in this cascade of information are subtle leading indicators of up-set operating conditions.
By definition, an estimate is an approximate calculation. This inherently infers that there is a certain amount of risk involved with any estimate. The risk will vary depending on the quality and the detail of the estimate and on the detail of the design information available at the time the estimate is prepared.
The quality and detail of an estimate is usually defined in the requested scope of services. An estimate can be an opinion of cost or a detailed estimate. The opinion of cost is an estimate prepared based on a professional’s best approximation of what a project will cost.
Construction claim consultants provide a crucial role when it comes to standard of care in construction. These specialized experts know every in and out of construction and civil engineering, and can help with project management and legal advice. Because these consultants know the industry well, they can help prevent legal troubles before they start.

Hiring an engineering expert shouldn’t be an arduous task, although sometimes the process may seem overwhelming. Usually the claim is at the point where you want answers yesterday but because of resourcing, workloads, or budgets you are in a time crunch to find them. Even if you are not initially intending to use the services of an expert, gaining access to certain portions of data during discovery is a proactive way to ease trouble or scrambling down the road. Whether it’s for a third party opinion, an independent design, a mediation statement, or a testifying expert, the engineer you hire will likely need information from the sources discussed below.
