Coconino County

These projects consisted of over 3000 LF of 72″ diameter CMP, building multiple styles of concrete channels, box culverts and utility relocates. Tiffany worked with Coconino County and their multiple design firms to get all of the materials delivered, pipe installed, channels and structures built, before the first big rain since the projects inception. Our crews worked long days, due to the importance of getting these projects completed, as the nearby homes have seen flooding breaching into their houses.

These projects consisted of repairing and bulding multiple watersheds in Flagstaff. Some of these project locations included the Wupatki/Lenox Watershed, Brandis/Thames Watershed, North and South Paintbrush, and others. Throughout these locations Tiffany has, and will continue to build mutliple alluvial fans, single and double rock sills of various sizes, and weirs. These systems help control the water as it runs off the mountain, and into additional drainage improvements surrounding the neighborhoods.

This project consists of four phases for the City of Sedona’s drainage improvement plan for Soldier’s Wash which runs through the T’laquepaque shopping village. After completing the new vehicle bridge and pedestrian bridge crossing last year, TCC has begun the rehabilitation and improvement of the channel. Beginning by clearing the channel of storm water debris, trees, brush and squaring up the wash profile, installation of RediRock and CMU block began. This block will prevent channel erosion while being aesthetically pleasing. Once the block installation is complete, the bottom of the channel will be lined with concrete furthering the erosion mitigation. These four phases included demolition, relocation of multiple sewer, water, gas and dry utilities, 4139 cy of excavation, 12,660 sf of Redi-Rock channel bank protection, 23,880 sf of 6” concrete channel bottom, 553 lf of CMU retaining walls, 55 cy of shotcrete, 226 cy of rip rap, 8’ H x 22’ W x 32’ L precast box culvert and 8 x 30 clear span corton steel pedestrian bridge and abutments. Working with the City of Sedona, T’laquepaque, Los Abrigados and El Portal management has ensured Spring Break season came and went with minimal interruption and visitor access and safety were maintained throughout all four phases.

Palo Verde Generating Station

Palo Verde Nuclear Generating Station (PVNGS), the nation’s largest power producer, brought together a team with TCC as the prime contractor to start the Generrex Project in August 2014. Since the commissioning of PVNGS in the 1980’s, this project is the first substantial addition to its power block. During the two years of construction our team constructed approximately 1500 cubic yards of structural concrete including structural slabs as thick as two feet and walls as high as 23 feet. Additionally, water lines, sewer lines, and fire lines were relocated under the strict protocols required at PVNGS before asphalt paving could be completed. This project has required extensive cooperation, communication, and coordination between all team members to ensure the schedule, budget, and stringent safety guidelines were met. With over 91,000 TCC man hours invested in this project, we are proud to say not a single incident occurred.

This project was created to remove and replace the failing gabion lined drainage channel installed during the spring/summer of 2011. Tiffany was employed to work with both county officials and the selected engineering firm (Kimley-Horn & Assoc.) on the design, constructability and budget for this project. We worked side by side with both entities providing design input and value engineering alternatives including budget reviews to insure that the project came in under budget. TCC met severe time constraints on both the design and construction phases of this project.

The project consisted of the removal and replacement of two and three-tier gabion baskets with a 6” concrete channel for the entire length of the drainage channel (2334 lf) in addition to traffic control and dust mitigation. Additionally the County requested work above and beyond the contractual scope of work, which Tiffany completed at no additional cost to the County through value engineering.

The project schedule was tight and work had to be completed prior to the monsoons. TCC placed multiple crews on the site to insure early completion. The adjacent property owners expressed their appreciation for the diligence and quality our crews maintained throughout the duration of the project. The gabion basket supplier (Macaferri) brought other gabion contractors to our site to “show them how the finished product should look”. Tiffany also assumed coordination duties with APS and Century Link for utility relocations relieving county officials from this burden.

Tiffany Construction was the contractor for the Design and Construction Phases of this CM@R project. During the design phase Tiffany met with the design engineer and provided constructability reviews, value engineering and prepared estimates for best value alternates. Also, TCC prepared a master construction schedule, traffic control plan, designed and reviewed the SWPPP plan, Sub-Contractor Selection plan, attended meetings with the city and design engineer and prepared the GMP. The construction part of the project included the excavation and installation of 1,760 LF of Storm Drain Channel. The major items of work include: 251 LF of dual 78” SRMP, 154 LF of dual 72” SRMP, 332 LF of dual 72” CMP, 410 LF of dual 78” CMP, 430 LF of 142” x 91” CMPA, 125 LF of 12” through 48” CMP, 14 LF of Concrete Transition Channel, 340 SF of Concrete Channel modification, custom grated headwall, custom junction structure, concrete channel with baffles, various removals, traffic control, landscaping, SWPPP construction staking, riprap swales, AC paving at street crossings and several other miscellaneous items.

Tiffany took over as both the Design and Construction Phase Contractor for this CMAR project after the contractor selected initially was not able to meet the City of Sedona’s budget. When we became involved in the design phase of the project, the plans were at 80% complete status. This provided us an opportunity to work with the city and design engineer to incorporate value engineering options and constructability reviews in a combined effort to achieve the budgeted amount. Tiffany not only was able to meet the city’s budget but we saved the city an additional $161,410 from the GMP. Also, we prepared a master construction schedule, traffic control plan, designed and implemented the SWPPP plan, Sub-Contractor Selection plan, attended meetings with the city and design engineer, and prepared the GMP.

Tiffany received numerous accolades from the residents and property owners for our communications and processing of the job and minimizing disruptions to all concerned.

L’Auberge was one of our most complicated projects to date. We were tasked with managing and coordinating the construction and redesign of one of Sedona’s premier resorts while the resort remained open. This project utilized and tested the skills of our project managers and foremen. Working closely with Shephard-Westnitzer’s design team, our project manager directed our crews in rock excavation, utility installation and site construction for 36 pre-manufactured cabins added to the existing resort including 19 cabins placed on the hillside, supported by caissons as well as a two level, 150 stall parking garage while coordinating with over a dozen subcontractors who were working simultaneously.

The unique challenges encountered here included:

• Maintaining a safe environment for the resort staff and quests
• Managing a multiple activities in an extremely small area
• Safely excavating a nearly vertical rock hillside for construction of a parking garage and new units
• Addressing the daily environmental protection of Oak Creek
• Working with multiple local and state agencies and utilities
• Readjusting the schedule and approach to allow for design changes and alterations

Dove Mountain Golf Course is an 18 hole Jack Nicklaus Signature Course. TCC performed as the general contractor for all earthwork. The project included a large drainage channel which was excavated and lined with soil cement, grouted and non-grouted riprap, concrete cut-off walls, and a small amount of shotcrete. The original design called for a concrete lined channel, however TCC proposed a value engineering alternate to the owner, which replaced the 6″ thick concrete channel with 48″ thick soil cement. Not only did this alternate provide a substantial cost savings, but it cut the construction schedule by two months. Our client was so impressed with our workmanship, professionalism and value engineering alternatives that they negotiated a second contract to construct an additional nine holes for Ritz Carlton at Dove Mountain.
