The intelliRock System - FLIR.com

The intelliRock SystemThe most widely adopted maturity-method system for profilingtemperature and estimating the strength of placed concrete:Accurate strength data from placed concrete forimproved quality control and safetyReal-time, on-site information to optimize workflow, reduceconstruction time and costComplete, rugged, easy-to-use systemIdeal temperature profiling system for mass pours and placements incold weather.“The intelliRock Systemhas been easy to use andallows us to pour andstrip forms like clockwork.It is very straightforward,either you havematurity and strengthor you don’t; the Systemtells you.”How intelliRock Is UsedBefore construction begins, a set of test cylinders are cast, several with Loggers embedded, toplot the relationship between compressive strength and maturity (degrees Celsius x hours) for thespecified mix design. At standard intervals – 1, 2, 4, 7, and 14 days – strength and maturity aremeasured. Results are graphed on a calibration curve:Bob Bolduc, P.E.QA/QC ManagerLane ConstructionWashington, D.C.,Metro ExtensionDuring construction, intelliRock maturity measurementsare plotted on a curve to accurately estimate concretestrength. Here, a maturity reading of 4000°C∙hourscorresponds to a compressive strength of 3800 psi.Hartsfield-Jackson AirportAtlanta, GeorgiaWith over 80 million passengers and 700,000 tons ofcargo passing through each day, Hartsfield-JacksonAtlanta International Airport is the busiest airport in theworld. As part of the current 10 year expansion project,Kiewit Southern Co. used intelliRock to execute a rapidreplacement of one of the airport’s main runways in under60 days. The intelliRock system reduced the overallcost to the contractor and owner. Material costs werereduced $200,000, penalties were avoided and the numberof test specimens needed was reduced by over 60%.

I-40 BridgeWebbers Falls, OklahomaOn May 26, 2002, a barge struck the I-40 Bridge nearWebbers Falls, Oklahoma, collapsing four spans and severingthe east-west interstate corridor. Oklahoma transportationofficials predicted a six-month reconstruction timeline.Using intelliRock, Gilbert Central Corporation, a subsidiaryof Kiewit, completed the job in 47 days, earning a $1.5 millionearly completion bonus.How intelliRock WorksintelliRock is a complete system, designed for convenience, ease of use, and low cost. Andit’s engineered to stand up to the rugged conditions of heavy construction sites.The system includes:Loggers. intelliRock Loggers, about the size of a 35mm film canister, contain a long-lifebattery, microprocessor, memory, and thermistor. Embedded in placed concrete,Loggers continuously calculate and store concrete maturity data (temperature and time). Atough casing protects the intelligent electronics inside; the only exposed partare the Loggers’ 18-gauge leads.Reader. The handheld intelliRock Reader is used to communicate with embeddedLoggers. Workers simply connect Logger leads at the Reader’s spring-loadedterminals and use the Reader to view and download maturity and temperaturedata. Readers also have a serial port for connection to an external computer.rockWare. Installed on an office PC, intelliRock Software facilitatestransfer of maturity and temperature data from the Reader to thePC in secure, unalterable electronic files for later distribution,documentation, and analysis.“Being able to measurestrength in real time is amajor benefit.intelliRock gave usreassurance that theconcrete was at a safestrength and we weren’tputting our people indanger, while at the sametime allowing us to gaintime on our schedule.

intelliRock BenefitsDelivering highly accurate, real-time temperature and maturity data, intelliRock ensures quality,safety, and cost-savings – and helps owners, engineers, and contractors make timely, intelligentdecisions:• Accelerated workflow to save days per pour – and weeks on large projects• Reduced expenditure for forms, equipment, testing, and man-hours• In-situ monitoring for accurate, economical temperature control• Improved safety, especially in cold weather when concrete is slow to cure• Rapid detection of mix inconsistencies for faster error recovery• Data integrity and assured accountability from uninterrupted,unalterable data• New opportunities to earn early completion bonuses.intelliRock AdvantagesintelliRock utilizes – and optimizes – the maturity method, adopted as an industry standard byASTM, ACI, NIST, and others, offering real advantages over traditional cylinder testing and othermaturity products:• More accurate than lab- or field-cured PCC test cylinders• Real-time data for faster decisions. No waiting for 2-, 3-, or 7-day breaks• A complete system for worksite and office convenience• Rugged Loggers protected by resin casing and surrounding concrete• Portable handheld Reader for easy on-site data display and download –anywhere, at any time. No need to carry heavy computers around the job site.www.intellirock.comEngius, LLC712 EastgateStillwater, OK 74074Tel 866-6ENGIUS(866-636-4487)Fax 866-277-8369www.engius.comEN_IROCK_030609© 2009 Engius, LLC.
