Humanity has often sought to utilize tools and technology to make working faster, more efficient, more comfortable, and more accurate. While humans may have started with stone tools, we have since developed complex and sophisticated mechanical and digital technologies. The construction industry has been utilizing construction technology and equipment for these same reasons for generations. While other industries have embraced the use of smart, autonomous technology and robotics, the construction industry has steadily fallen behind in this effort. In this paper, I will discuss current work using these tools and possible applications for future development.

Understanding Sub-Contractor Selection Factors In Thebuilding Construction Industry For The Southeastern United States, Dhaval Gajjar, Cayla Anderson
The Professional Constructor
The primary entities within building construction industry consists of the owner, the architect / engineer, and the general contractor, that ensure the success of any construction project. On a traditional project, the owner selects and contracts with the general contractor to construct a building designed by the architect. A considerable amount of research has been conducted to understand the owner’s selection factors to hire a qualified general contractor. However, the general contractor selected for the project seldom self-performs the entire construction of a building. The general contractor might self-perform some aspects of the actual building construction, but they will typically …

Multi-Skilled Labor Optimization With Partial Allocation Of Resources, Amira Saleh
Theses and Dissertations
The current practice of labor allocation in construction schedules assumes single-skilled workforce; meaning that each worker is assumed to be skilled in only one trade. In such practice, at any instance in the project lifecycle, some of the workforce become idle waiting for other labor types to complete their work. Traditionally, companies may relocate idle workers to other projects and return them back to their original project when needed again. This complicates the resource management process and is not often performed successfully, leading to schedule and cost overruns. Alternatively, project managers may keep the idle workforce at their projects because …

Project deviations and changes are one of the key common particulars encountered in the Construction industry. Project changes can occur in different forms, may impact different pillars of the project, and can be caused due to the existence of various underlying factors. Mismanaging or lack of controlling these changes is one of the key contributing factors leading to project hardships. Contractors incur profit erosion, scope creep, and time slippages mainly by failing to have an effective project change management system enforced within its project execution philosophy. Such adversity is amplified for contractors engaging in lump-sum turnkey “LSTK” projects. Contractors encounter …

Using System Dynamics To Study The Effect Of Change Orders On Labor Productivity, Shrouk Gharib
Theses and Dissertations
Change orders in construction projects lead to numerous negative impacts, including loss of labor productivity, delays, and cost overruns. Owners and contractors are usually in disagreement when it comes to allocating the extent of responsibilities with respect to the resulting overruns. Each party tries to hold the other party fully responsible for such overruns through a series of claims and disputes. Several delay analysis techniques have been developed to aid in settling such disputes, however, they do not fully grasp the rippled impacts of change orders and do not assist parties in reaching consensus when it comes to finding the …
