“I posted on Facebook about what a great job Joe and his crew did. Very polite, concerned about if I was happy with how things were going.

I was so happy I almost cried every time I went outside.  Place looks great, I so appreciate everything you all did to make this happen .

Thank you,”

“4Granite, Inc. has performed multiple construction projects for numerous departments at Boron Operations for over 5 years. These projects have included HDPE pipeline installations for various pumping system needs, concrete work, construction of utility buildings, dirt work and grading, tortoise fence installation, and assistance with reclamation projects just to name a few.

4Granite, Inc. has always been very easy to work with in each stage of a project from obtaining accurate estimates, contract negotiations, performing the work, responding to changes in plans during construction, and completion of projects. They are always willing to provide good input for ideas on how to improve designs and projects as well.

Many of the projects that 4Granite has worked on at Boron Operations have been under emergency/high stress circumstances where things could easily go wrong. 4Granite management and crews have always been able to rise to the challenge under these circumstances and get the work done in a safe and timely manner.

We have been very pleased with the performance of all of the crews that have performed work at our site as well as are very impressed at the safety culture that 4Granite, Inc. has adopted and instilled into their crews. The 4Granite work crews and project management have been amenable to adopt the Rio Tinto safety systems as their own or adjust their systems to more closely resemble those of Rio Tinto which has been very helpful. As such, 4Granite has been able to successfully complete the projects that they’ve been awarded with very low incident rates.

With the history of successful completion of projects and the positive safety culture of 4Granite, Inc. that we’ve experienced here at Boron Operations, I would definitely recommend further use of their services.”

“In just over one week, the Mine was able to dewater the K5 flat by pumping ~2.5 MGal of surface water from K5_1650 to Plant 10 where the water is being used for dust control…and 4Granite did a great job in helping this project be a success and getting the water out the pit in a timely manner. Thanks for all of the help and for doing such a great job!”

“I have worked with 4Granite Inc. on several complicated construction projects over the past 5 years with great results.  Joe Webb and his crews are extremely responsive with short lead times, capable of problem solving field issues, and complete projects with high level of quality craftsmanship.  They consistently meet or beat project schedules and budgets.  I will have 4Granite as my contractor of choice on future construction projects.”
