This document contains review comments from the Puerto Rico Highway and Transportation Authority (PRHTA) Design Area regarding a Geotechnical Investigation Report submitted by MGV Geotechnical Group, PSC. The report pertains to repairs at State Road PR-5556 Km 0.3 in Coamo, Puerto Rico.

Key points from the review comments include:

• Borings: Two borings (B-1 and B-2) were drilled, stopping at 30ft due to auger refusal. The borings disclosed interbedded cohesive soils overlying weathered rock.
• Recommendations: The geotechnical consultant recommended slope backfilling and installing Reno Mattresses. Geotechnical recommendations for subgrade preparation and backfilling are provided.
• Discrepancies: Boring B-1 revealed a soft Silty CLAY stratum from 8ft to 10ft, which was not specifically addressed in the report.
• Slope Stability Analysis: The review notes that slope stability analyses for final embankments were apparently not performed. PRHTA requires the consultant to provide a Global Stability Analysis with specific Factors of Safety (FSstatic ≥ 1.5, FSpseudostatic ≥ 1.125).
• Consultant Response: The consultant responded that road elevation will not change, and the depth is beyond the influence of traffic loads. Proof rolling will determine if subgrade reinforcement or replacement is needed. They also stated that no slopes to analyze were observed based on cross-sections.

This document is relevant to potential bidders as it highlights specific geotechnical findings and required analyses for the project. It points out potential issues with soil conditions and the need for further slope stability analysis, which could impact project scope, cost, and execution. Bidders should pay close attention to the required Factors of Safety and the consultant's responses regarding slope stability.

The damage is a result of Hurricane Maria in September 2017 and includes issues such as landslides, slope instability, washout, rock fall, and drainage problems.

• The project site is located on PR-1, Km 24.8, San Juan, PR.
• The damage is attributed to a shallow landslide of fill material and native saprolitic soils caused by erosion from overland runoff.
• The scope of work involves site reconnaissance, damage validation, investigations, studies, development of a technical report, and preparation of Plans, Specifications, and Estimates (PS&E).
• The proposed design aims to facilitate construction, reduce costs, minimize construction problems, and limit traffic interruption.
• The project will comply with FHWA's Emergency Relief Program and relevant PRHTA and AASHTO manuals.

Three (3) slope rehabilitation alternatives were evaluated:

1. Gabion Retaining Wall: Proposed from Km 24.81 to 24.88, with a length of 68.44 meters and heights ranging from 0.91 to 5.43 meters. This is the recommended alternative due to its strong base, ability to reduce water velocity, natural materials, simple handling, minimal impact on earthwork, and no need for road closure.
2. Reinforced Concrete Retaining Wall: Also proposed from Km 24.81 to 24.88, with heights from 1.20 to 3.62 meters. This option is the lowest in estimated construction cost but requires high-skill manpower and has a greater impact on earthwork cut.
3. Reinforced Soil Slope: Proposed from Km 24.81 to 24.88, with heights from 1.20 to 5.34 meters. This option is not recommended due to limitations in space and slope steepness, making it difficult to create a suitable base and place soil reinforcement without excavating a significant portion of the road. It is also vulnerable to erosion.

• The project length is approximately 0.09 Km (0.0559 miles).
• The estimated construction time for the proposed works is two (2) months.
• The estimated construction cost for Alternative I (Gabion Retaining Wall) is $538,045.95.

The project qualifies for Categorical Exclusion (CE) and is not expected to have significant environmental impacts.

The project is sponsored by FEMA and PRH&TA for recovery from Hurricanes Irma and Maria. It provides an analysis and recommendation for a gravity concrete wall (GCW) to remediate the landslide.

• Site Description: Landslide site at ER-HWY-83, PR-123, KM. 24.2, Municipality of Ponce, project code AC-801544.
• Cause of Landslide: Intense surface run-off and groundwater seepage from Hurricanes Irma and Maria, leading to erosion and undermining of earth fill and softer residua.
• Proposed Solution: Construction of a gravity concrete wall (GCW) at the crest of the downslope.
• Geotechnical Analysis: Includes overall (global) static and seismic stability analyses.
• Static Stability: A Factor of Safety (FoS) of 1.84 was obtained, satisfying AASHTO (LRFD) requirements.
• Seismic Stability: With a reduced seismic coefficient (kmax/kav by 50%), a FoS of 1.36 was obtained, exceeding AASHTO requirements for highway construction.
• Recommendations: GCW is acceptable if placed and proportioned as recommended. Backfill should be A-1-a selected granular materials, compacted to 95% of modified proctor maximum dry unit weight. Drainage swale at the top and an interceptor drain behind the GCW are recommended.

This document provides critical geotechnical engineering details for the landslide remediation project. Bidders involved in civil engineering, construction, or geotechnical services for infrastructure repair, particularly related to landslide stabilization and road damage, will find this information essential for understanding the site conditions, the proposed remediation strategy (gravity concrete wall), and the performance requirements under static and seismic loads.
