Subject: Addendum 1, Temporary Micropile Wall Shoring, Residence Addition, 320
West Bleeker Street in Aspen, Colorado
Dear Mr. Brainard,
RJ Engineering & Consulting, Inc. prepared temporary excavation plans for addition planned at
320 West Bleeker Street in Aspen, Colorado on May 5, 2020. Micropile shoring was installed
during the original house construction. We understand a below grade addition is planned for the
residence, and our current shoring plan utilizes new shoring installation in conjunction with the
existing shoring wall. As stated in note 4.5 for the original and current shoring plan, the design
life may be extended, if the system is inspected by a representative of RJ Engineering. For
reference, see note below from plans:
4.5 The design life on this micropile wall is 12 weeks. Design life is defined by the
beginning of excavation to backfill completion of the foundation wall. If the duration
of the project exceeds the 12 week duration, RJ Engineering shall be contacted to
evaluate the performance of the system and determine if the design life can be
extended.
RJ Engineering can inspect the existing shoring system at the time of the initial excavation to
determine if the micropiles and micropile cap are intact. We will then make a determination if
the system will perform as intended, or if additional shoring installation is required. If you have
questions or need additional information, please call us at 970-230-9208.
Sincerely,
RJ Engineering & Consulting, Inc.
Richard D. Johnson, P.E.
