Chile – Lepanto Landfill Leachate Treatment System
ZAPATA contributed to design and building of certain components for the operation of Lepanto Landfill. As part of this project ZAPATA added a train of pre-filtered gravel filters for the RIL and a carbon filter after treatment to significantly reduce the consumption of chemicals during the operation of the plant.
Fire Station #1
ZAPATA designed the expansion and renovation of an existing fire station at an Army installation. The existing structure is a circa 1950 concrete frame structure with masonry infill. The design called for the expansion of the gathering room, dayroom, and kitchen; renovation of the billeting space, Captain’s office/bedroom, and bathrooms; and removal of asbestos. The bathrooms were reconfigured to meet ADA requirements and updated with low flush fixtures. The design called for the demolition of mechanical and electrical systems and replacement with more energy efficient products. Windows in the renovated spaces are compliant with AT/FP and energy efficiency standards. ZAPATA was able to complete the design 45 days ahead of schedule and provide the complete sets of drawings and specifications.
FORSCOM/USARC Annex
ZAPATA designed the renovation and retrofit of the Old Bowley School to support the FORSCOM/USARC Headquarters relocation from Fort McPherson, GA to Fort Bragg. The renovated buildings will serve as the FORSCOM/USARC Annex during transition of the Command. The Old Bowley School is a historic, circa 1953, nine-building complex of 54,000 SF on a 14.5 acre plot. ZAPATA’s design included converting all the classroom spaces into private and cubicle workspaces; renovating three conference rooms (one capable for SIPR), three training rooms, several storage spaces, and a large auditorium; and upgrading all buildings to be ADA accessible. We coordinated design details with SHPO as the buildings are eligible for the National Historic Register. Value engineering studies resulted in savings of over $500K without loss of function. Design was LEED-Silver.
Geographic Information System (GIS) and AutoCAD Services
ZAPATA provided the Naval Weapons Station Charleston (WPNSTA CHASN) on-site GIS and AutoCAD Map services. These services included the development and implementation of base-wide GIS and associated services including support and guidance to developers and users of electronic mapping, application, and mission support data sets. ZAPATA provided data development, implementation, and program consulting services to WPNSTA CHASN Commanding Officer for the maintenance of base data assets, internet mapping assistance and training, publicity, help desk, and technical support for other military, civil service, and contractor personnel. ZAPATA was responsible for conversion of engineering data into a digital format; created and managed basewide geospatial data in SDS compliant CAD and GIS formats; educated Base Civil Engineering personnel on the use and benefits of SDS data; made presentations to management on the status of the base-wide GIS system and proposed pending improvements to the system; preparing facility maps to support short notice programming requirements for various departments and tenants at WPNSTA CHASN; developed responses to Base Realignment and Closure (BRAC) geospatial data calls in support of Command driven requirements; developed the overall enterprise GIS system.
Housekeeping Pad Replacement
ZAPATA successfully completed this design/build project to replace the existing fly ash housekeeping pad for electrostatic precipitators (ESP). The original concrete pad was poured several months earlier by a second tier contractor, which experienced drainage problems. A laser scan survey was conducted and drawings created showing contour elevations of the pad surface to ¼” intervals. ZAPATA recommended 13,000sf of the southern portion of the existing pad be removed and replaced with a new drainage configuration while matching the existing elevations of the pad where equipment remained. ZAPATA conducted geotechnical investigations to ensure the subsurface soil was properly compacted. 500 tons of aggregate base courses was added and graded by a laser guided motor grader to proposed subgrade elevations. 262cy of concrete were placed and finished in one continuous pour. The project was fast tracked and completed in 14 days.
Joint Base General Plan
The General Plan provides a tool to guide the installation commander and other decision-makers in the long-range development of the base. This Plan integrates a number of interrelated programs that appear as component plans to the General Plan. The Plan uses geospatially referenced data and makes it available to installation decision makers through the web by way of the installation’s intranet.
This General Plan is not prescriptive for base development. It provides the appropriate framework that is responsive to the dynamics of the planning process. The Plan is the evolutionary end product of the planning process and when coupled with the power of GIS results in more accurate, timely planning for base development. This Joint Base Charleston (JBC) General Plan is unique in that is combines the planning effort of Charleston AFB with Naval Weapons Station (NWS) Charleston and responds to the recommendations ofthe 2005 Defense Base Closure and Realignment Commission to realign installation management functions of NWS Charleston to the US Air Force.
Owner Representative Services
ZAPATA performed Owner’s Representative Services for a major addition and renovation to Southminster Retirement Community. Phases included an overall renovation and major addition to a 20-year old, 26-acre, Continuing Care Retirement Community. The project included the addition of two Independent Living Apartment Wings, the Wellness (Health Clinic) Center, indoor swimming pool and spa, and two underground parking garages. The Project also included the renovation of two dining facilities, and Activity Wing, and all independent living apartment buildings, and the Health Care Center. New buildings were up to eight stories in height, and the total extent was 406,000 SF of new and renovated spaces.
Structural Engineering Design Services
ZAPATA provided the structural engineering design for two new three story elevator shafts and corresponding lobbies at a three-story 151,000sf office building. ZAPATA also helped determine the existing building structural system and what could and could not be demolished on the third floor in preparation for the third floor up-fit.
Towle Stadium Renovations
ZAPATA provided complete design services for the renovations of the Fort Bragg Towle Stadium. The design focused on the replacement of the recreational playing surface with an artificial infill surface. ZAPATA designed an 81,000 SF synthetic turf field to replace the existing poorly drained grass field, including drawings, specifications, and permits. The synthetic turf design included field lines painted for four distinct sports. A fitness equipment location and layout were planned and designed. Site work included associated parking, drainage improvements, walkways, erosion control measures, utilities, and landscaping. Existing retaining walls and concrete stormwater conveyance ditches were inspected and identified for repairs and replacement as applicable. We also designed an accompanying men’s/women’s latrine building with storage capacity and stadium seating. The latrines will be heated by electric unit heaters with thermostats. Electrical service was designed to include interior lighting, stadium lighting and a scoreboard/message board, and sound system.
Utility Relocation for the Bank of America Corporate Center
ZAPATA performed an emergency design and provided construction oversight for the relocation of two, 20-inch chilled water lines and a large bank of fiber-optic communication lines servicing the Bank of America Corporate Tower in uptown Charlotte. Civil Engineering design included a 60-inch jack and bore under College Street (without disrupting traffic), shoring design for the receiving pit, utility vaults at critical turn points, and concrete duct-bank protection. Structural Engineering design included foundation and pipe supports for the two (now) 24-inch chilled water lines and the duct bank up the side of the nine-story parking deck; and three 30-inch penetrations of the existing building’s foundation and the replacement of structural steel. Main challenges included anchoring to existing construction and managing field modifications as required based on in-site conditions. Designs were completed and permitted in 30 days from the notice-to- proceed.
