This is not a solicitation for proposals, and no contract shall be awarded from this notice. PROJECT SCOPE: This event will discuss TWO separate potential contract actions. The primary purpose is to solicit feedback from the construction industry, specifically targeting contractors with expertise in deep soil mixing (DSM), deep mixing methods (DMM), and other innovative soil improvement techniques for seismic remediation of a dam with a very soft puddle clay core. Guajataca Dam Early Work Effort (Potential Contract 1): This scope of work includes but is not limited to utility (electrical, telecommunications, water and sewer) relocations, administrative office building demolition and relocation, traffic report and detour route, left abutment water supply siphon system and all incidental related work. All work affecting public roads, restricting public traffic, and involving utility relocations shall comply with Puerto Rico Highway and Transportation Authority�s Standard Specifications. Project Magnitude: For informational and bonding purposes, the estimated magnitude of this construction project is between $20M and $50M. Guajataca Dam Permanent Repair Project (Potential Contract 2): The scope of work for Guajataca Dam Permanent Repair Project includes repair construction of several major features to address significant risks relating to: Stoping of embankment material into karst and joint features in the right and left abutments, transverse cracking of the dam due to seismic loading, seismic deformation and cyclic softening of the puddle core leading to crest lowering and overtopping, concentrated leak erosion (CLE) through transverse cracks across the embankment caused by landslide movement, cracking and scour of the grouted riprap chute, and overtopping of the right side of the spillway causing embankment scour and stability failure. USACE is specifically seeking to engage with soil improvement and deep soil mixing contractors to address key project challenges, which include: Installation of vertical cutoff walls to address karst voids and a core stabilization wall to address embankment seismic instability. This includes installation through the dam�s very soft, hydraulically sluiced clay puddle core. Methodologies for working near and tying into existing concrete structures, such as a 1920�s era tunnel at the right abutment and a concrete key wall beneath the dam�s puddle core. Geometric limitations and constructability of deep mixing methods for creating a positive cutoff in difficult geologic conditions (i.e. karst). Logistical and equipment challenges associated with constructing a cutoff wall on the dam crest. Integration of large filter berms or stabilization buttresses on a dam with complex foundation characteristics (i.e. active landslide creep movements). Project Magnitude: For informational and bonding purposes, the estimated magnitude of this construction project is over $750M. LOGISTICS DATES: July 28-29, 2026 LOCATION: Puerto Rico Department of Economic Development, San Juan 355 F.D. Roosevelt Avenue, San Juan, Puerto Rico 00918 TIME: Day 1 - Registration on-site: 8:00am, AST Seminar and Q&A Session: 9:00am � 12:00pm, AST Day 2 � Site Visit to Guajataca Dam, time TBD The remaining agenda will be posted soon. An informative presentation will be provided with detailed information for the upcoming permanent repair project for Guajataca Dam, Puerto Rico. The focus will be on the scope of work (repair plan measures), construction considerations, acquisition strategies and timelines, and contracting requirements. Attendees should RSVP for the event, if interested, at earliest convenience. Attendees are also encouraged to submit questions via ProjNet in advance to allow us to focus on areas of particular interest, but active and open discussion will be encouraged throughout. INSTRUCTIONS TO PARTICIPANTS - RSVP In order to prepare a list of attendees of individuals participating in this Outreach Event Day, it is requested that an e-mail be sent to Contract Specialist, Ronica Smith at ronica.r.smith@usace.army.mil and cc Contracting Officer, Renee Booth at meranda.r.booth@usace.army.mil, no later than (NLT) July 24, 2026, at 2:00 pm, AST. In your email, please include the following information: firm�s name name and title of those individuals participating contact number and e-mail address Specify type of business, Small Business Category (if any), UEI Information and if you would like to participate as a Prime or Subcontractor. REQUESTS FOR INFORMATION Questions: The Government will address questions the day of and after the event. Attendees will be given the opportunity to submit written questions during the presentation; index cards will be provided. Aside from the Outreach Event Day, all questions must be submitted through ProjNet (See instructions below). All questions and official/approved answers will be posted in ProjNet. INSTRUCTIONS FOR SUBMITTING QUESTIONS Questions relating to this event and the permanent repair project are to be submitted via Inquiry Key IK23KZ-9HBXRZ in ProjNet at (https://www.projnet.org). To submit and review inquiry items, participants will need to use the alpha-numeric key IK23KZ-9HBXRZ and follow the instructions listed below the key for access. A participant who submits a comment/question will receive an acknowledgement of their comment/question via email, followed by an answer to the comment/question after it has been processed by our technical team. All timely questions and official/approved answers will be made available through ProjNet. Official/approved answers to all timely questions will also be posted on the Sam.gov website in the form of a report generated from ProjNet when all answers are finalized. We appreciate your questions and feedback by 5:00 pm, AST on July 31, 2026. Note: Please indicate the name of the project when submitting your questions.
