Some major items that were included with the renovations was the Presidential Suite upgrades which included a major bathroom renovation which included the addition of a soaking tub, shower renovation and updates throughout.
In the early 1980’s we built our first F.D.O.T. project, built many mid-size local roads and added building construction services to facilitate the construction of the Lowry Park Zoo. By the late 1980’s, we were the prime contractor for many sewer and water treatment plants, mass transit facilities, streetscapes, parks and athletic facilities in addition to our roadway construction. We also teamed with the City of Tampa to construct the first design-build roadway project in the bay area, the Bayshore Blvd. Realignment.
Demolition
The original Town of Belleair Public Works Facility was established in 1968 to house the existing various departments of public works. After years of use, the main Public Works building and truck bays became in disrepair. The building became infested with termites; the bays had structural damage; and the discovery of asbestos was found in certain areas of the facility. In 2012, the Town of Belleair’s Public Works management team along with the Design/ Build team of David Nelson Construction and Klar and Klar Architects developed a new plan to combine all of the various divisions into a new sustainable, Category 4 Hurricane Resistant facility. In addition, the new facility also serves as the Town of Belleair Emergency Operations Center and works in conjunction with Duke Energy to secure and protect a service vehicle f or use during times of emergency. The scope of work included concept development, design, permitting, demolition of the existing public works facility, construction of a new 10,784 S.F. Public Works Facility, and associated Sitework. The 10,784 SF Public Works facility is comprised of a 3,156 SF administration building constructed with concrete block, a 3,470 SF workshop constructed with Pre-Engineered Metal Building, and a 4,158 SF Equipment Parking Bay constructed with Pre-Engineered Metal Building. The new facility was constructed on the same parcel as the deteriorated existing facility and required construction to be completed in two phases. The first phase included construction of the 10,784 SF facility and surrounding Sitework and was completed in less than 7 months. Once the Town occupied the new facility, the deteriorated existing facility was demolished and the parking lot was completed. This project was awarded the American Public Works Association 2014 Project of the Year-Structures.
The project comprised of furnishing all labor, materials and equipment to construct, approximately 2,050 LF of varying width concrete walkway with a portion cantilevered over water, existing seawall repairs, providing an ADA compatible walkway for bikes and pedestrians, connecting the Riverwalk from the Straz Center to Water Works Park, including such features as benches, planters, shade structures, railing, public art, decorative lighting, landscaping and irrigation, seawall repair.
Fencing
This project consisted of multiple phases of airfield rehabilitation throughout the Tampa International Airport including Runway 1L-19R, Runway 1R-19L, and Runway 10-28 as well as most of the taxiway system. Major work items included the removal and replacement of approximately 4,000 SY of existing 17”-thick Portland Cement Concrete pavement, 2,600 SY of econocrete base, repair of 400 LF of cracked concrete slabs, 1,900 SF of spall repair, resealing 505,000 LF of concrete joints, remarking of approximately 500,000 SF of airfield markings and the re-paving of 9,500 SY of lime rock base and asphalt on the Runway 1L Blast Pad. Project also consisted of security fencing, excavation, sodding, airfield lighting, runway grooving and fire hydrant installation.
Gate Replacement/Installation
Asphalt Paving
The Longleaf Neighborhood 1 & 2 Improvements Project consisted of the installation of storm sewer inlets and pipe to assist in the drainage of the roadways, the stabilization of the roadway around several grate inlets to repair settling that has occurred, the installation of sidewalks in a number of the park areas within the neighborhood, installation of brick pavers in several intersections within the two neighborhoods and the milling and resurfacing of the roadway in both neighborhoods. All of this work was done while maintaining traffic throughout the neighborhoods and access to all residences, as well as minimizing disturbances to the surrounding area and returning all disturbed areas back to their original conditions. Project elements included maintenance of traffic, clearing, earthwork, replacement & installation of new storm drainage, utility relocations/offsets to accommodate the new storm drainage, curb and gutter, sidewalks, stabilization, base, asphalt paving, concrete brick pavers, signing and pavement marking, lighting, irrigation and sod. The project required extensive coordination and phasing to maintain residential traffic as well as existing drainage throughout the project. All of the work was completed while maintaining the traffic flow on the existing roads utilizing multiple detours and construction phases.
Excavation
Bear creek was a 20 to 30 foot wide meandering creek located in South Pasadena in Pinellas County, Florida. The creek is a tidal waterbody which empties into a lagoon area which then flows into the intercostal waterway. Years of heavy growth and sediment was causing a large sediment buildup in the lagoon causing water quality problems. This project for DNCC involved 2,000 linear feet of channel widening (30 foot bottom width) and dredging approximately 6,000 CY of contaminated sediment by barge from the lagoon as well as 21,000 CY of machine excavation from the creek so as to realign, widen, and deepening the creek to 30 foot wide. With the new creek alignment, approximately 9,750 tons of rip rap rubble bank and shore was installed along the new bank slopes and 1,645 LF of new steel sheeting seawall was installed. A sea walled concrete sump approximately 45 feet by 210 feet was constructed with weirs so as to trap future sediment for annual removal.
Retaining Walls
Some of the specific elements included 750 CY of new concrete seawall cap and wall, 593 CY of retaining walls, 3,126 SY of colored concrete sidewalk with black beauty aggregate and a sand blasted finish, 2,500 LF of new helical pull down micro piles installed under two existing bridges, 2,600 LF of new stainless steel wire hand railing, a new stainless steel enclosure under the Laurel Street bridge, and 1,871 LF of French drain behind the existing seawall.
Walkways
This project was a challenging and diverse project for Nelson. Over 11 acres had to be renovated with underground piping, specialty construction and landscaping. At the entrance of the park, outstanding timber archways were built to support festive hand painted logos, displaying a variety of animals exhibits. On each side of the arches at the entrance gates are two 3 story steel frame cedar clad and trimmed structures, connected with a second story timber covered walkway. These structures house the Zootique Gift Shop, Administration offices, conference center, concession area and outdoor eating areas along with general offices and restrooms. Twelve dramatic fountains surrounding a unique aqueduct manatee and calf are highlighted with granite and brick walls. Ample seating benches allow visitors to sit back and enjoy the view. In completing this project, Nelson used up-to-date state-of-the-art animal containments to create a natural environment for the diverse animals. Nelson also built a viewing tower and walkways around natural settings for birds in the wild. This project won the 1988 ABC Excellence in Construction Award.
Some of the major elements within this project were 6,000 SF of newly poured 3,000 PSI concrete, an entirely new roof, and a 10 ft garage door for easy accessibility. All parts of this project molded together and made a truly beautiful landmark.
This project included the construction of a 48,000 SF banquet and convention center including conference and meeting rooms, kitchen, dining facilities, lobby and eating areas. The project scope also included the development of a four-acre site including parking, loading dock facilities, landscaping and irrigation. Nelson Construction self-performed all sitework, concrete and masonry. Construction of the Carnelian Center was a major accomplishment since it is one of the areas largest facilities of its kind and was dramatically designed with special features. The sophistication and beauty of this complex is a showcase of Nelson Construction’s top quality building skills.
Electrical Work
Hillsborough Area Regional Transit Authority (HART) implemented the Marion Transit Center (MTC) Improvements project to develop the existing parking lot facilities for HART employees and provide access for the public to the newly constructed MetroRapid Marion Transit Center Bus Station platform. In October of 2013, DNCC was awarded the contract by HART to perform the development services for the existing MTC parking facilities. Our scope of work included the maintenance of traffic, lane closures, clearing and demolition, earthwork, utility relocations, 231 LF of sanitary sewer utility lining, storm drainage, paving limestone base material (2,005 Tons), asphalt paving installation (118.15 Tons), concrete paving installation, curbs, sidewalks, concrete pads, bike racks, trash receptacles, landscaping, irrigation, signage, pavement markings, generator enclosure, generator installation, electrical services and lighting. One major aspect of the project included the installation of an emergency generator for the existing Marion Transit Center. This improvement allows HART to operate the MTC in an emergency state, to provide services to the public for whatever situation might arise. This ability also allows the MTC to operate as a “Command Center” in the event of one of these emergency situations might arise. This project involved obtaining separate right of way, road closure and electrical permits from the City of Tampa. Despite a few delays due to permitting issues, we were able to meet the required dates and HART was able to open the newly improved MTC Parking Lot Facilities to their employees and public in March of 2014.
