EPC Contractor Benefits
EPC means "Engineering, Procure, Construct". These are companies like Bechtel, Fluor Daniel, Foster Wheeler, Black & Veatch, Kellogg/Brown and Root, Parsons, Raytheon, etc. These are the companies that are responsible for all facets of the project, even for operating it prior to turning it over to the owner. Time, efficiency, reliability, and quality are very important, but most important is CONSTRUCTABILITY.
EPC contractors have embraced SQUIRTER® DTIs with a vengence. Making the whole bolting process simpler and more efficient is what these companies are all about. Field bolting can consume 20 to 30 percent of the field labor to construct steelwork, and a 25 percent saving in this labor quickly adds up, they report.
How do DTI's improve constructability?
- One-side, one-man bolt tightening, saves labor cost.
- No torque wrench inspection, saves inspection cost.
- Higher more consistent bolt preload, because DTI's are not controlled by torque.
- Bolt quality checked - very important when the source of bolts is suspect.
- No part-turn procedure to verify on every bolt as when turn-of-nut is used.
- DTI's function correctly whatever the condition of the bolts and nuts.
- Allows metric bolt installation - there are no approved part-turn procedures for metric bolts.
- DTI's are manufactured to suit any bolt made in the world.
- Proves to Owner that the bolting has been done correctly, even if it was done by low skilled workers in foreign countries.
- DTI's function correctly when the steelwork is hot dipped galvanized, even though the zinc surface is compressible. DTI's are the only tightening method which will work correctly in this situation.
