Quattrocchi Kwok Architects

“For well over ten years I have had the opportunity to work with Alten Construction on projects from modernizations to complex alteration and new construction involving phasing, difficult site conditions and tight time frames. In all cases Alten Construction exceeded my expectations and did so in ways that ensured the school’s schedule and budget goals were met…Once selected (unanimously) by the selection committee, Alten Construction set out to help us with the constructability review and cost estimating. With concern over the rising cost of steel and energy, and its impact on budget, Alten collaborated with the district and design team on cost savings including multiple subcontractors bidding to ensure the budget was met.”

“To say that this 3 month modernization was a Herculean task would be an understatement. I remain convinced at this time, 2 weeks prior to occupancy that no other construction firm in the Bay Area could have handled such a task and pulled it off successfully. I have become fond of calling Alten the “Seal Team 6” of construction and would recommend them without qualification.”

“Alten Construction has been more than a developer in the Hoover Elementary project—they have acted as a true partner. The president, vice president of operations, project manager and superintendent at Alten Construction all rolled up their sleeves and sought solutions instead of sidestepping substantial complications.”

“I’ve had the privilege to work with Alten Construction since 2012, during which time they have provided an excellent team of well-established and experienced professionals. Their work on the La Tercera Elementary School Modernization Project was outstanding, as was their level of professionalism, attentiveness, attitude and performance. Their ability to perform under budget and ahead of schedule, which is virtually unheard of during a fast track summer schedule, was remarkable.”

“The Alten team, whether on site or office staff, has been a pleasure to work with. The construction was well planned, organized and scheduled. No surprises. The field Superintendent was very familiar with school work and DSA requirements. He ensured that all work was properly completed before I received the Inspection Requests, and that Inspection Requests to me or to the Special Inspection firm, on site and off site were submitted in a timely fashion. There were no construction deviation notices issued.

Alten has a very collaborative, problem solving approach to project management that included the IOR in all construction matters. In several instances they were able to work with the IOR and architect to suggest suitable changes do to ‘discovered’ conditions that were then DSA approved.

As an experienced IOR, I would look forward to working another project with Alten, and strongly recommend their services.”

“They know their business and their approach and manner of doing business works well as a team player with the owners and their other consultants. Alten I might add knows their business well and as such can in many cases lend their expertise to the Districts Management Team and in that position improve the success of a project to the benefit of the district.”

“I have found Alten Construction to be a responsible, organized and timely contractor that works proactively to resolve potential issues before they occur. In my experience, they have always conducted themselves with the highest level of integrity. I would absolutely recommend them for public works or private projects involving K-12 schools.”

“It is a rarity to see owner’s personally involved with any project of any size but Bob Alten and Shannon Alten, the company’s two owners and principals were intimately involved with the project from beginning to the end. They provided assurances along the way that the project would be completed on time and lived up to this challenging commitment.

Trevor Simon, Alten’s superintendent was instrumental in making certain that Alten completed the project on time. Despite the very aggressive schedule, Trevor was always patient, calm and able to accommodate the owner’s requests be it logistics, shut down’s or modifications. Trevor has a vast understanding of school construction and coordinated the work flawlessly. I would recommend Alten Construction on your upcoming school project(s). ”
