About the NCS Reston Branch

The National Capital Section's Reston Branch hosts regular monthly technical meetings at ASCE Headquarters in Reston at lunch time. Formerly a Committee of the Section, it was, in late October 2017,  anointed a Branch in recognition of its successful track record of serving members from the Reston area with well-attended PDH and networking opportunities. Several Branch Officer positions have opened up for our member volunteers to fill. Take advantage of these emerging leadership opportunities!

Jan 27, 2020 (Reston): Design and Structural Interaction of RAP & RIS

Click HERE to register.

This talk will provide an introduction to the design and structural interaction of Geopier Rammed Aggregate Pier (RAP) & Rigid Inclusion systems with shallow spread footing and slab on grades.

These systems are ground improvement technologies that can be used to increase bearing capacity and control settlement of buildings, tanks, retaining walls, and embankments to close tolerances. Depending on site requirements, Geopier systems can be installed using replacement or displacement methods. RAP systems are used to reinforce good to poor soils, including soft to stiff clay and silt; loose to dense sand; organic silt and peat; variable, uncontrolled fill; and soils below the ground water table. They can be used as an alternative to deep foundations or over-excavation, and provide cost and time savings on sites where building on existing poor soils and/or undocumented fill present unacceptable risk to the owner.

This presentation reviews fundamental Geopier design and construction techniques and discuss the collaborative effort between the project structural engineer and RAP designer needed for a successful project.

WHEN: Monday, Jan 27, 2020, 11:45 AM - 1:00 PM (Sign-in and catered lunch begin at 11:45 AM, with speaker at 12:00 PM)
WHERE: ASCE Headquarters - 1801 Alexander Bell Drive, Reston, Virginia, 20191
COST: $25 per person (member) $20 (life member) $30 (nonmember)
Attendees will receive (1.0) Professional Development Hour (PDH).
