intelliRock Studies

Commercial & Public

CEMEX/Baker - CEMEX HQ.pdf 
The 325,000 square foot CEMEX headquarters is one of the largest green buildings in Houston. What made this possible? Use of a leaner mix design containing fly ash and a maturity program with intelliRock. This combination also saved money, kept the project on schedule, and earned LEED points for the environmentally-conscious owner.

Fiatech-Amgen Opus Project in Puerto Rico 
FIATECH, a research & development consortium for the construction industry, has published a report titled "The Use of the Concrete Maturity Method In the Construction of Industrial Facilities: A Case Study." The report describes a field trial conducted by Fluor Corporation personnel over two months during the main concrete placement phases of the Amgen Opus Project in Puerto Rico. The report reviews the concrete maturity method, describes the technology, and describes field experience in trials of that technology.

University of Arkansas Harmon Avenue Parking Facility 
The initial driver for adopting the intelliRock system on this $30 million, nine-level, multiple access parking facility was to enhance the project's critical path. But on the first elevated deck pour, intelliRock revealed that the concrete delivered did not meet the specifications. These deck sections were removed and replaced, setting the job back over 30 days. Using intelliRock removed an average of a day or more of curing "wait time" from each concrete placement, helping recapture half of the time lost.

Flintco, Inc.-University of Oklahoma Football Stadium 
Flintco Inc. is adding 8,000 seats and 27 suites to the University of Oklahoma Memorial Stadium as part of a $52 million, 18-month project. At a cost of less than $5,000, intelliRock has saved Flintco $309,000 in man-hour costs.

McCarthy -4th Avenue Jail Project, Phoenix, AZ 
On the Maricopa County 4th Avenue Jail project, McCarthy Building Companies Inc. did not have to wait for seven-day lab results to strip forms and reshores. Thanks to real-time, in-place concrete strength data from the intelliRock system, McCarthy saved man-hours and money by renting less form-work and cycling it faster.

Flintco, Inc. -Marriott Courtyard, Oklahoma City, OK 
Flintco, Inc., is completing an eight-story, 225-room Marriott Courtyard hotel in downtown Oklahoma City, Oklahoma. Using the intelliRock system optimized post-tensioning and provided reliable temperature profiling during cold-weather concrete operations, which saved one day per pour during the project.


Roads and Bridges

I-10 Hurricane Damage Reconstruction 
Hurricane Katrina slammed into the Mississippi and Louisiana Gulf Coast on Monday, August 29, 2005 resulting in numerous bridges being damaged or destroyed. The I-10 east bound bridge over the Pascagoula River and adjacent marsh was badly damaged by two runaway barges. The barges destroyed six of the bridge spans rendering the eastbound bridge impassable. Mississippi DOT reacted in a timely fashion and on Wednesday, September 7 they received four bids from various contractors. The project was awarded to TL Wallace of Columbia, MS for a 31-day contract to repair the bridge with a bid of $5.4 million. The contract called for $100,000 per day in potential damages. The same metric was used as the basis for determining the early completion incentive.

Zachry Construction Corporation-Dallas High Five Interchange 
Zachry Construction Corporation is on track to earn a large portion of $11 million in bonus for early completion of the Dallas High Five interchange. Use of the intelliRock system for measuring concrete maturity is one of the reasons why the project is 38 percent completed after only 18 months.

I- 40 Bridge Reconstruction-Gilbert Central Construction (Kiewit) 
When a barge collided with the Interstate 40 Bridge near Webbers Falls, Oklahoma, collapsing multiple spans, state transportation officials predicted a six-month reconstruction schedule. The intelliRock system played a major role in helping complete construction in just 47 days, which earned the contractor a $1.5 million early completion bonus.

Gohmann -I-65 Paving Project, Indiana DOT 
The intelliRock system provided Gohmann Asphalt & Construction with a powerful QC/QA tool for a performance-based paving contract. Not only did it provide documentation of compliance with strength criteria, it helped ensure that cold weather concrete placements were within temperature specifications, helping earn the company a significant bonus.

Pavers, Inc.-City of Wichita, KS 
Using intelliRockT, Pavers Inc. learned that it was obtaining strength for concrete it placed faster than destructive testing methods indicated. As a result, it was able to open pavement sooner for businesses and residents, and recover time lost to weather delays.

Duit Construction Co., Inc.-Interstate 30 Project 
Cold weather threatened to set an Interstate Highway paving job back between six to eight weeks at the outset of the project. Using the intelliRock system, the paving contractor was able to monitor the in-situ temperature of the pavement in real-time, providing the owner with necessary quality assurance data to allow the contractor to proceed as scheduled.


Special Applications

Washington Metro Area Transit Authority-Blue Line Extension 
Using the intelliRock system on the Washington Metropolitan Area Transit Authority Blue Line Extension project to optimize concrete workflow operations has been an effective, economical alternative to purchasing additional traveling forms. Furthermore, intelliRock provides the concrete maturity data and QC/QA information needed to keep the project moving on schedule, even during the cold weather months.

Fugro South, Inc. - Augered Cast-in-Place Piles, Houston, TX 
Evaluation of Grout Strength Gain within Augered Cast-in-Place Piles using Concrete Maturity Meter. The rate of strength gain for concrete or grout is essential information when determining the load carrying capacity of a recently placed structure. New technology in maturity meters allows for embedded components to be used in lieu of external recording devices, making the use of these instruments more feasible on job sites.
