What our clients are saying

As you are aware, your company was referred to us by Lloveras, Baur & Stevens to do drainage, swale grading, installation of drainage piping, etc. and subsequently hired by the Board to do the work. In addition as the original work was nearing completion we added two additional areas that needed drainage work. The Board wants to commend Jon Winowiski, Supervisor, over this project, and his workmen for the excellent and professional job they did. They excelled in their work in difficult areas of space, tree roots, etc. Then they encountered our unmarked water pipes and had a break, the repairs were made in a timely fashion. Working in a residential area of senior adults can be challenging and Jon answered the resident’s questions and addressed them professionally. We would be glad to give you a referral and should we encounter a need in the future for additional work in this area we would count it a privilege to have your employees back on our property to do the work. Thank you for fitting this “smaller” project into your calendar.

Director & Project Manager

Keystone Excavators was awarded a contract by the City of Oldsmar, Florida to construct a one-million, five-hundred fifty-two thousand dollar project in July 2010 for a new water supply pipeline for a future reverse osmosis facility. The scope of the work consisted of well-lined site piping, raw water by-product discharge main, and a complete operational fiber-optic communication line. This complex project has required Keystone Excavators to work closely with virtually every permitting agency. Agencies include City of Oldsmar staff, the Department of Environmental Protection, Southwest Florida Water Management District, Florida Department of Transportation, CSX Railroad and numerous consulting engineers. Keystone Excavators’ construction team provided many cost-savings ideas for the city of Oldsmar and has met every budget and schedule requirements by the City of Oldsmar’s management team. The integrity and professionalism exhibited by Keystone Excavators’ team made for a great working relationship with the City of Oldsmar.

The City of Clearwater is extremely pleased with the performance by Keystone Excavators on the Ream Wilson Trail – Long Center Design. We would like to express our appreciation for the professional manner in which your employees conducted themselves and the extra mile in scheduling to complete the phasing of this project to accommodate the grant funding process. The value of this project was $767,119.00, consisted of constructing 1,600 lineal feet of 11’ wide concrete multiuse trail, tree aeration system, pre-engineered steel pedestrian bridge beginning at the Long Center Facility and through the two heavily wooded areas of Northeast Coachman Park and Coachman Ridge Park.

The project was complicated for the contractor because of a stipulation of minimal disruption and compaction of the ground around existing large trees which required extreme care by the equipment operators in maneuvering during clearing and grubbing, tree removal of hazardous trees and construction of the multipurpose trail as it meandered through the natural wooded parks. Co-ordination was extremely important due to moving heavy equipment and ready-mix concrete trucks in a very narrow corridor without disrupting the root systems or damaging the tree canopies. None of the 100 plus trees adjacent to the multiuse trail were lost during the construction of the project.

The project had a very aggressive timeline because of grant funding time constraints. Keystone Excavators accomplished the original project scope of work requirements, but also executed additional scope of work items, such as; resurface existing asphalt parking lot in Coachman Park and improvements to drainage issues at the Long Center and Coachman Ridge Park. Scope of work additions were accommodated and change orders were priced fairly (majority of the new scope of work items were based on set unit prices in the contract), this allowed the work to flow in a co-operative atmosphere and helped bring the project within the budgeted costs and on time. The key to the success of this project is due to Keystone Excavators because of their performance on the Ream Wilson Trail – Long Center Design project.
