• 5.4 Approach / Methodology <br /> The following methodologies and practices are utilized to fulfill project requirements: <br /> • Site work and excavation: Medallion uses experienced in-house construction <br /> crews to install erosion control and perform mass excavation. While installing <br /> erosion control, crews utilize methods determined to be the most effective, <br /> practical means of preventing or reducing pollution from nonpoint sources. Mass <br /> excavation is performed using the widely accepted practices of setting <br /> elevations using a surveyor and a rotary laser level. <br /> • Drains and aggregate base: Medallion uses the same in-house construction <br /> crews who perform the erosion control work and mass excavation to install the <br /> field's drainage and base components. Similar to excavation, crews use survey <br /> points, rotary laser level, and a pipe laser to accurately install drainage <br /> components. Before installation of aggregate base, a proof roll is performed on <br /> the entire field to ensure the sub-base meets specified stability and compaction. <br /> Any bad spots are dug up and repaired by backfilling with stone and dry dirt, <br /> and rolled and compacted to meet specified compaction. The aggregate base is <br /> installed in "lifts" beginning with the installation of the first layer of #57 stone <br /> (specification name may vary in state of Florida). This is followed with <br /> installation of a layer of #78 stone. Lastly, a layer of fine crush stone is applied <br /> as a leveling and choke layer. All stone is installed by bulldozers and box blades <br /> all that have dual slope lasers attached for accurate grade and slope. Planarity of <br /> base and final grades are checked upon completion by a 10'x 10'. <br /> • Turf and underlayment: Medallion uses specialized in-house turf installation <br /> crews who assume installation responsibility once the stone base work is <br /> complete to install the synthetic turf. Installers are trained to work carefully on <br /> the laser graded stone base to ensure base integrity. Medallion uses the double- <br /> lock stitch sewing method to seam the main field (or belly) panels together. <br /> Head seams and butt seams are glued using a 2-part adhesive supplied by the <br /> turf manufacturer. Medallion orders the turf panels such that the maximum <br /> number of game lines are tufted into the panels. For inlayed game lines <br /> installers use the widely accepted sheer and glue method. Medallion uses top of <br /> the line turf sheers and hot melt device to install game lines. Lastly, turf <br /> installation crews install the infill using turf brooms to stand up fibers, <br /> broadcasting top dressers to install the infill, and drag brooms to level and settle <br /> the infill product. <br /> • Medallion is committed to maintaining a high degree of quality assurance <br /> throughout the construction and installation processes. The project manager <br /> and crew superintendents are constantly monitoring construction to ensure <br /> specifications are met or exceeded. Project managers track installation quality <br /> with in-house quality assurance documents that ensure each step of the job is <br /> fully completed before crews move onto the next phase of work. <br /> Medallion Athletic 6 <br /> Products, Inc.
