In-Situ Mechanical Characterization For Compacted Aggregates, Douglas Cortes, Paola Bandini
Publications
The evaluation of compacted unbound aggregate layers is perhaps the most common undertaking in transportation-related projects. The assessment of compaction compliance in engineered fills, subgrades, subbases, and bases in roadways and railways is central to ensure longevity of ground transportation infrastructure. In many cases, premature failures in roadways that originate in the unbound aggregate layers can be traced back to inadequate compaction. These failures are preventable, provided the problem areas can be identified by a suitable field test during construction. The most widely used method for compaction assessment during construction is the nuclear density gauge (NDG) test. While the device …

A Comparative Analysis Of Key Elements Of The Strategic Decision-Making Process Across Construction Professional Services Firms: Evidence From The Irish Construction Industry, Oluwasegun O. Seriki, Roisin Murphy Dr
Conference papers
The Irish construction industry is experiencing a well-established growth phase following a prolonged recession. While the economic impact has been well documented, there remains less emphasis on discipline-specific studies pertaining to strategy within construction firms in Ireland. Additionally, evidence regarding strategic management within the construction sector is predominantly concentrated on contracting organisations, with less emphasis on highly knowledge-intensive professional service firms (PSFs). As the construction sector in Ireland continues its sustained growth, there have been increased calls within the industry for further collaboration between key stakeholders. However, exploring collaboration within project-centric firms without understanding the individual strategic decision-making processes within …

Examining The Microeconomics Of Bid Difference Of Engineer & Contractor Bids In Highway Construction, Robert Ryan, Randy R. Rapp, Mark Shaurette, Sarah Hubbard
The Professional Constructor
This study examines microeconomic factors that affect Bid Difference between the designer’s Engineer’s Estimate and the contractor’s Winning Bid. Historically, the accuracy of the Engineer’s Estimate and the Winning Bid vary. To account for this discrepancy, the Federal Highway Administration (FHWA) recommends a contingency be included in all Engineer’s Estimates. Statistical analysis was performed to determine if state Departments of Transportation (DOTs) were currently meeting the recommended Bid Difference values. Data was collected from California, North Carolina, and Ohio from 2012 through 2014. Statistical analysis indicates that current practices to develop an Engineer’s Estimate met the FHWA recommended values. With …
