Project: Thurgood Marshall School

The construction project for Thurgood Marshall School was to restore an abandoned historical building to convert it into a charter school for the District of Columbia. Because this project entailed restoring all motor joints and the façade, ACI had to face the challenge of replicating the fascia panels and broken stones that had to match the existing ones. ACI replaced all the broken bricks, regrouted over 70 percent of the motor joints, refabricated the sheet fascia, and replaced slate pavers, which all had to match the existing ones. This project was completed on time within budget, and the customer was very pleased with the result of this restoration process.

 

Project: 303 RTU New Support, U.S. Department of Commerce

ACI recently completed a project on the fire station – NIST building 303. This project entailed removing the rooftop unit and the steel curb. Then, according to the project specification, a new concrete platform was formed and poured in order to support the structural steel support system where the removed air handling unit was to be reinstalled. In order to restore the HVAC system of the building, ACI also worked on the electrical, mechanical, and pluming aspects of the project. The entire construction work was completed within budget and 8 weeks ahead of the schedule, which proved that ACI is able to work efficiently and flexibly.

 

Project: Osbourn High School & Baldwin Elementary School, School of the City of Manassas

For this project, the school buildings underwent construction in order to remove the existing roofing system and to identify and rehabilitate the substrate and its structures to provide structurally sound school buildings. ACI replaced the perimeter wood nailers and the water damaged lumber tectum roof decking that had been damaged by infiltration of moisture in the library of the elementary school. The existing roofing had many leaks, damaging the exiting roofing insulation, which was compromising the thermal value. ACI removed the entire roofing insulation and replaced it with a thicker insulation system. Due to the combination of narrow siding and roofing on the existing structures, many details that were not indicated on the drawing had to be handled case by case. In addition to working on such detail-oriented tasks, ACI spent an immense amount of time on scheduling, coordinating, supervising, and taking extra caution to prevent ancillary damages and to protect students and facilities. Despite the difficulty of performing construction work during regular school sessions, the project was completed successfully, 10 weeks ahead of the schedule, within budget, and without any owner or contractor initiated change orders.

 

Project: MD National Guard Armory, State of Maryland, Department of General Services

ACI's construction project for the National Guard Armory, located in the Aberdeen Proving Ground, had to be scheduled with its occupants in mind due to the fact that it is an active training facility. According to the carefully planned schedule, ACI successfully removed and replaced numerous condenser units for HVAC on the roof. Furthermore, the brick exterior that was leaking water into the building was pressure washed and water proofed prior to the roof replacement. The project was completed on time within budget, its result fully reaching customer’s expectations.

 

Project: 231 Waterproofing, Department of Commerce

This project required the back fill around the basement entry way to be excavated away from tunnel walls to expose the existing the foundation drain and the drainage for the mechanical duct bank. ACI surveyed the existing storm drain line elevation to determine whether the foundation drain elevation was high enough to discharge into the existing strong line nearby. Once it was determined that this was possible, new foundation drain had to be excavated with great consideration for underground utilities that may be present. ACI also repaired the walls of the entry way where water proofing was damaged. Along the walls, a new drainage median membrane had to be applied on the entire length of the wall to relieve any hydrostatic pressure off the wall and to direct the ground water into the newly installed foundation drain. Once on the ground the work was completed, the final grading and landscaping had to be performed to provide stability for sediment and erosion control. This complicated process was completed on time within budget with customer satisfaction.
