What the GCs say
They poured 212,000 square feet in eleven nights and hit every F-number. We did not have a single grinding day.
Hardline took down six storeys between two occupied buildings and we never got a call from the neighbours.
The daily reports are better than ours. Quantities, photos, tomorrow’s plan, every night by six.
Twenty-two months on a live plant campus, zero recordables, zero shutdowns we caused.

Bid questions
What estimators ask us
How fast can you turn a bid?
Five business days for anything under $5M, ten for structures. If your bid date is tighter, call and we will tell you honestly whether we can do it justice.
Do you self-perform or broker?
Everything on our scope list is self-performed with our own crews and our own iron. We do not broker concrete or demolition to anyone.
What is your EMR and safety record?
EMR is 0.71. All supervisors carry MIOSHA 30 and we run weekly documented toolbox talks. Full mod-rate letters go out with every bid package.
Can you pour in winter?
Yes. We pour to 15°F with blankets, heated enclosures and adjusted mixes, and we write the cold-weather protection into the price rather than as an extra.
Are you bonded?
Bonded to $12M single, $30M aggregate. Bonding company letter available on request.
What about the material you take out?
Concrete is crushed and reused on site wherever the spec allows. We diverted 86% of demolition material last year and the tickets are in every close-out package.
