Realising Electronic Purchasing In The Irish Construction Industry, Alan V. Hore, Roger West
Realising Electronic Purchasing In The Irish Construction Industry, Alan V. Hore, Roger West
Conference papers
The use of Information Communication Technologies (ICT) in construction purchasing has been sporadic and piecemeal. Very significant inefficiencies and problems still exist in both paper transactions and non-integrated electronic solutions. At the simplest level, the electronic transmission of business documents offers savings in paper and postage. By going a step further, businesses can make strides in communicating with their partners, at relatively low cost, through direct links between their computers. Existing ICT such as the Internet, Bar-Coding, Radio Frequency Tagging, Electronic Data Interchange (EDI), Electronic catalogs and Enterprise Resource Planning Software (ERP) have facilitated electronic commerce (EC) functionality within many …

Evaluation Of Current Incentive/Disincentive Procedures In Construction, Brad W. Rister, Yuhong Wang
Evaluation Of Current Incentive/Disincentive Procedures In Construction, Brad W. Rister, Yuhong Wang
Kentucky Transportation Center Research Report
This study was initiated to take an in-depth look at the current time and material incentive/disincentive program associated with highway construction projects in Kentucky. The current incentive/disincentive program was first initiated in the mid to late 90’s. However, not until recently had some of the original mechanisms of the program been revisited and/or up-dated.
From the early stages of this study it was anticipated that many of the concerns regarding the use of both time/material incentives and disincentives on highway construction projects in Kentucky would be addressed. Therefore, at the onset of this project the study advisory committee made a …

Nu-Deck Precast Deck Panels And Innovative Bridge Research And Construction, Maher K. Tadros, Charles J. Vranek
Nu-Deck Precast Deck Panels And Innovative Bridge Research And Construction, Maher K. Tadros, Charles J. Vranek
Nebraska Department of Transportation: Research Reports
Most of the deficiency in existing stringer-type bridges lie in deterioration of the bridge deck. Cast-in-place reinforced concrete decks experience cracking shortly after construction due to large differential creep and shrinkage with the supporting beams, and due to the temperature drop experienced during the hydration cycle. The NUDECK (Nebraska University) system is a full-depth precast/prestressed concrete bridge deck panel system. The combination of high performance precast concrete, where little creep and shrinkage occur after the deck is made composite with the beams, and two-way prestressing assure continued pre-compression of the deck during its life. With this system, construction time and …

Efficacy Of Speed Monitoring Displays In Increasing Speed Limit Compliance In Highway Work Zones, Jeanne Marie Bowie
Efficacy Of Speed Monitoring Displays In Increasing Speed Limit Compliance In Highway Work Zones, Jeanne Marie Bowie
Theses and Dissertations
Safety in highway work zones has become a concern among Departments of Transportation (DOTs) throughout the country as the highway network has begun to age and more maintenance and construction work has been necessary. Safety in highway work zones is more compromised than in other areas for two reasons. First, the construction workers are near traveling vehicles as they perform their already dangerous work, increasing the risk of an accident. Second, the highway user is at increased risk because of the increase in roadside obstacles, because other vehicles are more likely to act in unpredictable ways (such as sudden braking …
Assessment And Modeling Of Stream Mitigation Procedures [2003], Bernadette S. Dupont, Sudhir Palle
Assessment And Modeling Of Stream Mitigation Procedures [2003], Bernadette S. Dupont, Sudhir Palle
Kentucky Transportation Center Research Report
As population increases, so does the need to improve and augment the road network. Construction of new roadways or modification of existing roads often requires diversion or modification of streams. If a stream is disturbed, government regulations require mitigation or compensatory replacement of the affected area in a similar environment. Stream mitigation is of particular importance in Kentucky, as Kentucky ranks second in the United States for having the most miles of waterways. Consequently, stream mitigation has become a significant factor in roadway construction costs. To date, no studies have been made to assess the execution of the mitigation plans …
