Construction Engineering & Project Management

Building and maintaining infrastructure in a timely and efficient manner is critical for the advancement of society. The mission of KTC’s Construction Engineering & Project Management group is to perform research that improves the development and delivery of infrastructure projects, with a focus on safety, cost, schedule, and quality. The group’s researchers have collaborated extensively with the Kentucky Transportation Cabinet and over the past five years have quickly risen to national prominence through a series of projects undertaken as part of the National Cooperative Highway Research Program (NCHRP) and on behalf of the Construction Industry Institute. Work for the NCHRP has focused on topics such as construction staffing issues and strategies, optimizing the utility coordination process, the use of alternative contracting, and transportation agencies’ use of mobile information technologies. Research on construction safety issues and the craft workforce has been funded by the Construction Industry Institute. The group also conducts work on topics ranging from project closeouts and building information modeling, to the use of aerial imagery that facilitates project delivery.

Construction Engineering & Project Mangement – New & Research

KTC Presents at the 2017 Partnering Conference

KTC is pleased to take part in the 22nd Annual Partnering Conference in Louisville KY. The Conference will be held August 15-17, 2017 at the Galt House hotel, and features over 35 engineering-focused continuing education sessions to choose from and a couple of evening events you won’t want to miss!

On Wednesday August 16th, Construction, Engineering, & Project Management, Program Manager/Associate Professor Dr Tim Taylor & Research Engineer Roy Sturgill will present KYTC Utility Coordination Training Overview from 10:00-10:40 am and from 10:00pm-10:40am and again at 3:00-3:40pm.

This presentation discusses present methods to improve the efficiency of utility relocations, which would help reduce negative project performance impacts or delayed project start dates. They will address Kentucky specific legislation and regulations regarding utility coordination in highway projects. This session will cater to multiple stakeholder groups including utility coordinators, designers and project managers, consultants, utility companies, and construction and permits staff.

Methods to Expedite & Streamline Utility Relocations

The co‐location of utilities within and near road and highway right‐of‐ways presents challenges to the Kentucky Transportation Cabinet (KYTC) in the construction and maintenance of transportation infrastructure. The largest overall issue is that in most instances KYTC cannot directly manage utility relocations. Relocations are typically performed under the direct supervision of the utility owner/operator. KYTC projects may experience negative project performance impacts or delayed project start dates due to unfinished utility relocations. Developing a method to improve the efficiency of utility relocations would help to mitigate the negative impact of utility relocations on KYTC projects.

Safety Concepts for Workers from an OSHA perspective

KTC examined the safety culture within highway construction and researched the safety best practices of highway construction workers. Those practices will be included in training that enhances the Cabinet’s worker safety programs and policies. After analyzing 3800 job safety incidents and evaluating policy in several other states, a job safety analysis tool was developed to improve the safety performance of KYTC projects. For each work task, the JSA provides information on the number and severity of incidents and offers mitigation and control techniques. The tool considers OSHA safety concepts for workers, and does not take into account workzone safety.

Bridge End Settlement Evaluation and Prediction

A bridge approach is usually built to provide a smooth and safe transition for vehicles from the roadway pavement to the bridge structure. However, differential settlement between the roadway pavement resting on embankment fill and the bridge abutment often creates a bump in the roadway. KTC examined historic data on maintenance and inspection from a wide range of Kentucky roads to find methods for predicting settlement severity. The important factors that influenced settlement were: geographic regions, approach age, average daily traffic (ADT), the use of approach slabs, and the foundation soil depth. Researchers developed two models based on those factors that will predict the approach settlement level for a new bridge or an existing bridge. Prediction of bridge approach settlement plays an important role in selecting proper design, construction, and maintenance techniques and measures.

Change Orders and Lessons Learned

Many times, change is necessary for the success of a project. “Change, defined as any event that results in a modification of the original scope, execution time, or cost of work, happens on most projects due to the uniqueness of each project and the limited resources of time and money available for planning” (Hanna, Camlic, Peterson, & Nordheim, 2002). While change orders are necessary to address unforeseen conditions and other unavoidable or unanticipated occurrences, they tend to negatively affect construction. In most public works, change orders are the main reason for construction delays and cost overruns (Wu, Hsieh, & Cheng, 2005). Change orders also lead to a decline in labor efficiency, loss of man hours, and costly disputes (Moselhi, Assem, & El- Rayes, 2005). It is important to understand the impact change orders have on project performance, but it is also important to understand the cause of change orders. Before change orders can be handled properly, owners must be aware of the reasons behind change orders. This research examines change orders on Kentucky Transportation Cabinet projects and focuses on identifying the leading cause of change orders, identifying the types of changes orders that produce the highest risk, and developing a procedure for pricing change orders.
