PROJECT: HDD OF 20” HDPE FM AT MIAMI INTERNATIONAL AIRPORT
SCOPE OF WORK
The 20” HDD FM for the Miami Internatonal Airport (MIA) serves as the marquee project in our roster; exhibitng Our Team’s commitment to ensure that all our clients concerns are met. The main transmission line at MIA was a 20” cast iron force main (FM); running along NW 21 Street. The FM was a crucial component of the MDWASD Wastewater Transmission system, as it received the majority of the flows from the MIA sanitary sewer collecton system. Due to various factors, the most important of which was age, the force main failed, causing sewage overflows in and around MIA. The nature of the project required an emergency response with an expedited schedule. It was decided by MDWASD and MIA that a trenchless opton would be used to install the new force main; thereby mitgatng the risk of complicatons and prolonged down‐tme. The scope of services for this project included the design and constructon of 800 LF of 20” HDPE force main by horizontal directonal drilling (HDD). The purpose of the project was to replace a failed secon of an existng force main, servicing the Miami Internatonal Airport (MIA). The project was vastly complex, requiring extensive coordinaon to ensure proper alignment, radius of curvature, and entrance/exist angles that would allow the minimum clearance between existng utli‐tes. Additonal coordinaon was required to facilitate a clear path for the directonal drilling below Ramps K, I, and L that service the MiamiIntermodal Center (MIC). The project required constant communication with the contractor, as the team worked around the clock to deliver the project within the ght schedule. The project’s expeditedschedule was met; both in the design and constructon phase. A wellexecuted design and close coordinaton with the emergency opera‐ton contractor allowed constructon to take place within a week’s tme, with no major setbacks. The design was started on January 25, 2010 and completed in a week. By February 15th, 2010 the new line was already in service. Arnelio Alfonso, P.E. (APCTE) was the project manager of the project; overseeing all facets of design and construction.

PROJECT: PERRINE CUTLER RIDGE WATER & SEWER IMPROVEMENTS
SCOPE OF WORK
The scope of work was comprised of an upgrade to the existng water and sewer system in the area to beter meet the aggregate demand of several large scale future developments. The existng system was undersized and, in many cases, did not service a significant porton of the area. These condi‐tons inhibited commercial and residental development. MDWASD aspart of the water & sewer improvements for Perrine‐Cutler Ridge, proposed the installation of 12” and 16” watermains, new fire hydrants, and the expansion of the gravity sewer system in order to route flows to the new public sta‐tons. The project was divided into three Basins and it served an area of approximately 181 acres.
Overall the project included approximately 20,000 LF of water main, 23,000 LF of sanitary sewer, 8,000 LF of force main, and 3 pump statons; with a constructon cost totaling $17.8 million. MDWASD completed the project in a cost and tme effectve manner; overhauling the water and sewer system in the area, and providing public water and sewer services to many propertes.

The existng system was comprised of undersized water mains, old water mains, and in some cases no water mains in the project area. The land use is com‐mercial, industrial and residenal; and mostly served by undersized water mains or private wells. Addionally, a vast majority of the area was serviced by sepc tanks, private li staons, and in a few cases public sanitary sewer systems.
The water distributon scope of work was comprised of approximately
18,000 LF of 12” WM and various other water mains ranging in diameter from 6”‐16”. The upgrades will also provide fire protecton and improved pressures to the neighboring commercial, industrial and residen al propertes in the project area.
The new sanitary sewer system included: various 8” D.I. gravity mains. There is approximately 18,000 LF of 8” sanitary sewer and about 5,000 LF of 12” sanitary sewer. These gravity lines routed flows to the new pump statons. Flows were then transmited via a new 12” DIP force main to a 54” Transmission Main. These improvements eliminated the need to maintain the smaller public and private li statons in the area, which in turn is a savings to the owner. Arnelio Alfonso, P.E. (APCTE) was the project manager of the project; overseeing all facets of design and constructon.

Our Team worked around the clock coordinating with the contractor, pipe manufacturer, and owner to mitigate the risk of possible construction delays. Ater evaluating the scenario, a specialty contractor was brought on‐board to assist with the sub‐aqueous crossing; thereby turning the project into a hybrid between a design‐build and conventional hard bid project. During the entire process E plus coordinated closely with MDWASD to ensure that their best interests were met at all times. This included contract negotiations with the contractor and implementing innovative solutions to limit manufacturer related production delays. E plus, as the Engineer of Record, provided production plans & specific tons, secured all required permits, and provided construction management services as required. Additional efforts by our team included a buoyancy analysis of the pipe, due to its large diameter, and 3D modeling to provide QA/QC during the pipe’s construction.
