About this file

Written by GovTribe AI · Mar 31, 2025

This document is an Earth Retaining Structure (ERS) Inspection Report from the Massachusetts Bay Transportation Authority (MBTA) for a specific structure located in Walpole, Massachusetts, with the Structure ID Fr-NB-19.06-B on the Franklin Line. The inspection was conducted on 10/15/24 and covers a 195-foot timber crib wall with a maximum height of 7 feet and a minimum height of 1 foot, supporting two railway tracks. The structure carries rail/transit services and is situated adjacent to a pedestrian sidewalk, with a main structure condition rating of 3 (Poor) and a secondary element condition rating of 3 (Minimum).

The inspection report reveals significant structural concerns, including 4,100 square feet of reinforced concrete wall facing with documented issues such as cracking, delamination, and exposed rebar, as well as 400 linear feet of concrete footing with potential grade heave/settlement and horizontal rotation problems. While no specific repair costs or immediate action items are explicitly detailed in the submitted document, the poor condition rating suggests that maintenance and potential rehabilitation will be necessary. The report includes comprehensive documentation such as inventory forms, condition ratings, element field condition data, photo logs, and space for maintenance/repair recommendations, indicating a thorough professional assessment of the earth retaining structure's current state.
