Type of Work: Evaluation and repair design to address structural deterioration and waterproofing issues at four (4) existing plazas that were constructed upon four (4) individual one (1) level below grade pre-cast pre-stressed concrete parking garage structures. The project was broken into four (4) separate phases and involved the enhancement and modernization of the plaza hardscaping and landscaping, removal and replacement of the plaza waterproofing and the implementation of certain structural repairs to the foundation walls to address structural cracking issues.  The landscaping design incorporated an intensive planting system that covered approximately one third of the garage structure below while the plaza area received a pre-cast concrete paver in a pattern along the side of and within the private patio areas. Planter walls and stand alone planters and wood privacy fencing was installed at the plaza level. Under a prior rehabilitation phase, the garage soffit (ceiling) located immediately below the plaza structure also received column repairs as well as strengthening in the form of grouted coupled reinforcing bars to address the tendon bond loss encountered in the hollow core planks at isolated locations. An expansion joint was installed at the transitions between the plaza deck and the adjacent structures.

SRG’s Role: SRG was retained to perform an investigation of the plaza deck waterproofing system and perform a condition assessment of the plaza’s and garage structures. Based on our findings SRG developed a design package for the plaza and garage structural repair, and waterproofing replacement. SRG also worked collaboratively with the Owner to develop the architectural finishes and materials they desired for incorporation into the plaza hardscaping design. This design package was competitively bid after which SRG assisted the Owner in the contract negotiations and performed construction observation and contract administration services during the plaza and garage construction phases

SRG is proud to say that this project received an award from the International Concrete Repair Institute (ICRI).

Type of Work: Evaluation and repair design to address structural deterioration and waterproofing issues at a one level elevated parking deck that was constructed over an on-grade parking garage. The project involved a one-way joist and beam system that was in disrepair. The concrete structure was surveyed and repaired after which the deck was overlain with a membrane waterproofing system. A guard perimeter wall was constructed and water management devices were installed to collect and control storm water runoff. A cast-in-place concrete topping slab was installed over the membrane waterproofing to provide a wearing surface for the vehicular and pedestrian traffic.

SRG’s Role: SRG was retained to perform an investigation of the concrete parking deck and waterproofing system and perform a condition assessment of the overall parking structure. Based on our findings, SRG developed a design package for the garage structural repairs and parking deck renovation as well as waterproofing system replacement. The design package was competitively bid after which SRG assisted the Owner in the contract negotiations and performed construction observation and contract administration services during the plaza and garage construction phases.

Type of Work: Concrete parking deck repair and partial replacement of cast-in-place concrete one-way joist system, epoxy injection of structural cracks, application of vehicular traffic bearing coating system, grouting of void space discovered below the slab-on-grade sections of the garage and negative side waterproofing of the below grade foundation walls.

SRG’s Role: SRG was retained to investigate extensive concrete deterioration in the garage’s concrete deck and develop a remedial repair design package that was then used to solicit competitive bids. SRG assisted the owner in the contract negotiation phase and performed construction observation and contract administration services during the construction. One of the challenges of the project was the presence of mechanical and storage rooms located immediately below the work area which needed to be kept operational through the project.  During the construction phase, an odor consistent with fuel oil became evident, which appeared to originate from an abandoned underground exterior storage tank.  SRG interfaced with the EPA, DC Environmental Health Department, and the tank removal contractor to minimize the impact of the tank removal process on the foundation wall adjacent to the garage work zone.

Type of Work: Evaluation and repair design to address structural deterioration and waterproofing issues with an existing plaza and two-level garage structure, enhancement and modernization of the plaza hardscaping and landscaping, associated structural strengthening, removal and replacement of the plaza waterproofing and expansion joint systems and replacement of a large steel framed building entrance canopy.

SRG’s Role: SRG was retained to perform an investigation of the plaza deck waterproofing system and perform a condition assessment of the plaza and garage concrete structure. Based on our findings SRG developed a design package for the plaza and garage structural repair, and waterproofing replacement. SRG also worked collaboratively with an Architectural firm who was retained by the Owner after an interview process that SRG facilitated. The selected Architectural firms then worked in unison with SRG in the development of new plaza features given the structural limitations of the existing construction. Where strengthening was required SRG facilitated in the design of the structural alterations and external (carbon fiber) reinforcement design. This design package was competitively bid after which SRG assisted the Owner in the contract negotiations and performed construction observation and contract administration services during the plaza and garage construction phases.  During the construction, major changes to the architectural features were made by the Owner to include a fountain and sculpture and SRG developed the necessary structural design modification documents and worked with the Contractor to avoid major delays and excessive cost overruns. An interior designer was retained to develop a new canopy design with an intricate wood finish and this canopy construction was coordinated into the plaza and garage project. The landscaping incorporated an extensive planting design that would accommodate the plaza’s limited superimposed dead load capacity. The project resulted in an enhanced appearance that is very attractive and requires significantly less annual maintenance.

SRG is proud to say that this project received an award from the International Concrete Repair Institute (ICRI).
