Key West, FL. 33040
Keller Project No. 13121088
Mr. Pinto
Keller was subcontracted last year on 9/20/2022 for permeation grouting work at the above-
mentioned project. The permeation grouting work is an engineered temporary shoring system for
the existing foundations for protection to allow for adjacent excavation of the new foundations.
Contractual grouting scope was based on the addendum 1 structural drawings dated 4/22/2022.
New conformed structural drawing set has been released dated 5/5/2023 and the grouting scope
has increased based on structural changes, material escalation and logistical challenges. This
narrative is to describe the permeation grout scope increases and change order request.
Two areas have been identified via dashed black lines along the proposed foundations by the
FOR which would require temporary shoring, see figures 1 and 3 for 4/22/2022 set. Proposed pile
caps were designed requiring excavation elevations noted on the figures. Latest 5/5/2023 set for
construction was released and pile caps were redesigned to shallow foundations, see figures 2
and 4 for details. New shallow foundations increased the overall footprint and excavation depths.
See below for summary of drawing changes.

For additional change order backup, Keller has included shop drawing comparisons in figures 5
through 8. This details differences between contract and revised permeation grouting scopes.
Please note injection pipe increases and injection volume increases. Scope increases impact
installation durations, spoils handling and material increases.
Summary of scope changes
• An additional 6,850 gallons of drilling and injection required.
• Additional work will require a 6-day increase to our current schedule.
• Contract work duration of 1.5 weeks plus 5 day cure time
• New work duration will be 2.5 weeks plus 5 day cure time.
• Night work required.
• Material escalation increase from 2022 contract date to anticipated mob date of
October 2023.
o See exhibits A and B for material quotes.
• Drill access required from south entrance, requiring additional cable length for
electric drill.
o See exhibit C for cable quote.
Keller is requesting a change order in the amount of$106,320.76 for additional drilling and
grouting required based on the structural drawing updates for conformed structural set
dated 61612023.
If we can be of any assistance in clarifying any points in this letter, please contact us at (954)
