Opportunity Lost: Mismanagment Of The Closeout Phase Of Construction Projects, Jared Rogers

Purdue Polytechnic Masters Theses

In nearly every construction project, completing the project on time is one of the most critical things for everyone involved. Late project completion causes a wide variety of complications for the entire project team. This paper seeks to identify some of the causes for delay in the last phase of construction projects: the closeout phase.

Original research was conducted to gather input from construction industry professionals about their experiences with the closeout phase of projects. Factors perceived to cause closeout delay were identified, along with perceptions about the closeout performance of survey participant’s firms. The research validated the study’s premise …

This report provides information on revenues, distributions, and expenses of state and local governments for highway, road, and street work. Since the Motor Vehicle Highway (MVH) and Local Road and Street (LRS) Accounts are the principal source of funds for local road or street construction and maintenance operations, this summary may be used to see the trends in income sources and in the expenses charged to the funds prior to their being distributed to the highway, road, and street agencies.

Documenting The Construction Of A Plain Concrete Bridge Deck And An Internally Cured Bridge Deck, Carmelo Di Bella, John Schlitter, Neal Carboneau, Jason Weiss

Indiana Local Technical Assistance Program (LTAP) Technical Reports

Durable and long lasting concrete is important, especially for bridge decks, which are susceptible to premature cracking and corrosion of the reinforcing steel. To increase the durability of the concrete and its service life, many transportation agencies use high-strength concretes. However, high-strength concretes often have problems with early age cracking due to shrinkage. These cracks can then open a path for chloride ions (found in road salts) to reach the reinforcing steel. The results of this research, which compared bridge installations on two structures in Monroe County, Indiana, confirm that internally cured concrete presents a better alternative to traditional plain …

Super Flex Wall - New Frame System For High Rise Buildings, Purdue Ect Team

ECT Fact Sheets

The "Super Flex Wall" is a structural frame method newly developed by the Takenaka Corporation, used in combination with a core wall (the earthquake-resistant reinforced concrete wall penetrating through the center of the building from the lower part to the top floor) and a structural control method or with a base-isolation method. Part of the structure is cantilevered from the central core along the periphery of the building.

Carbon Frp Grid Structures For Use In Reinforcing Concrete, Purdue Ect Team

ECT Fact Sheets

Carbon FRP Grids are structural reinforcement materials that improve the performance of concrete structures such as insulated wall panels, architectural panels, double tee parking garage tee beams, concrete countertops and other products. The carbon grids can be used in place of welded wire mesh in most structures and is imbedded the same way as a welded wire mesh.

Pvc Stay-In-Place Panel Covers For Tilt-Up And Pre-Cast Construction, Purdue Ect Team

ECT Fact Sheets

Octaform™ stay-in-place concrete forming system is PVC insulated concrete form system. These forms have been used in the industry for various applications to improve the insulation and corrosion resistance of structures. Octaform™ has developed the panel covers so the advantages of PVC stay-in-place concrete forming systems could be applied to tilt-up and pre-cast construction.

Conx Space Frame System, Purdue Ect Team

ECT Fact Sheets

Off-site manufacture is one of the key initiatives being used by contractors to achieve these goals. Sandwich Plate System (SPS) Floors deliver a compelling off-site solution for structural floors. Their composite steel panels provide a similar performance to concrete floors at one quarter the weight, 10 - 15% shorter project schedules and broader benefits such as reduced complexity and the elimination of the majority of wet-work above ground level.

Evaluating Net-Zero Energy Houses From The U.S. Department Of Energy Solar Decathlon 2011, Jordan P. Wallpe, William J. Hutzel, Gregory Lasker, Clark Cory

School of Engineering Technology Faculty Publications

The Solar Decathlon is a two year, international project where university students compete to design, build, and test energy-efficient, net-zero homes. By definition, net-zero energy houses annually produce as much electricity as they consume. The 2011 Solar Decathlon, held in Washington D.C., had 19 university teams from around the world.

Unfortunately, many past Solar Decathlon houses have traditionally been very costly. However, the 2011 Solar Decathlon was the first competition to have an affordability contest. The affordability contest required each home to be valued under an estimated builder’s cost of $250,000, forcing the teams to select economically feasible solutions for …

Contour Crafting, Purdue Ect Team

ECT Fact Sheets

Victims of disasters such as floods, earthquakes and war have to seek shelter elsewhere. A need arises to rapidly construct houses on site and at minimal cost. This will eliminate the need to transport pre-fabricated shelters long distances, saving the time and costs associated with transportation. Since Contour Crafting is an automated process, labor needs are highly minimized allowing relief workers to allocate their time and effort to rebuilding local infrastructure such as water sanitation and distribution systems, roads, electrical and communication systems as well as irrigations systems.
