Why TurnaSure is the easy choice for your project
Installation Savings with TurnaSure's Bolting Devices:
Over 50 years ago an early study conducted in London, England1 concluded that using Direct Tension Indicators (DTIs) reduced installation time by 25% when compared to the ‘part turn’ (aka Turn-Of-Nut) method. The study proved that, managed correctly, use of DTIs saves much more in labor costs than the procurement cost of the DTIs themselves.
The same study described above was recently reanalyzed by Rowan University, adjusting for current material and labor costs and comparing the DTI to the calibrated wrench method (as it is used in the EU). Half a century after the initial study, the relationship between DTIs and cost savings remains strong. The savings in labor cost using DTIs exceed the current cost of DTIs in both the EU and USA.
Reduced Inspection Costs with TurnaSure's Bolting Devices:Independent 3rd party bolting inspection services can run upwards of $100 per hour. Time really IS money, and the time required to inspect your project can be dramatically reduced with the use of TurnaSure Direct Tension Indicator (DTIs). Inspection is easier, quicker, and simpler with Direct Tension Indicators. In addition, DTI inspection can be handled by a single inspector, whereas calibrated wrench inspection typically requires the work of a two-person crew. Similarly, the laborious 'match-marking' and inspection of the 'turn-of-nut' method is eliminated.
A recent study concluded that the bolting service Inspection Costs could be reduced by 42% by using TurnaSure DTIs. An early study by Bethlehem Steel at a power plant in Nebraska found significant savings on bolting service inspection costs on a side-by-side comparison of two projects, only one of which used DTIs.
Costly Rework is eliminated with TurnaSure's Bolting Devices:TurnaSure Direct Tension Indicators (DTIs) not only save on bolting service installation and bolting service inspection costs but also provide assurance that 100% of all bolts have be tightened correctly thus eliminating costly erector call-back, schedule disruptions and loss of productivity. The hourly rate for an Iron Worker can be easily exceed $125 per hour and the need to call back two Iron Workers for rework can cost thousands of dollars.
