Montemor-Biscainho Street Redevelopment Project

Municipality of Coruche

Introduction

This article details the requalification project for Rua de Montemor, located in the parish of Biscainho, municipality of Coruche. The intervention, part of a plan by the Coruche City Council for the rehabilitation of streets southwest of the municipal headquarters, focuses on paving and modernizing infrastructure. The study was based on military cartography and georeferenced topographic surveys (scale 1/500), ensuring a rigorous technical basis for the execution project.

Context and Need

Currently, Montemor Street is unpaved, serving as access to various plots and properties scattered throughout the area. The street presents spatial restrictions due to the consolidated presence of perimeter walls and existing infrastructure, which limits the available width for the layout in several places.

The need for this project is related to the urgency of providing visual continuity to the street and, fundamentally, ensuring safe and comfortable conditions for users, with a special focus on pedestrians. The absence of paving and structured pedestrian paths motivated the creation of a solution that maximizes the available space, adapting to the threshold levels and the concentrated buildings present along the street.

Summary of the Project Completed

The technical solution developed by Envisquantis focused on the functional and structural rehabilitation of the roadway, respecting a base design speed of 50 km/h.

• Geometry and Layout: With approximately 2,337 meters in length, the project respects the materialized altimetric and planimetric layout. The new grade was implemented between 15 cm and 20 cm above the current elevations to ensure the homogeneity of the pavement.
• Transverse and Pedestrian Profile: Implementation of a traffic lane with one lane in each direction. Elevated sidewalks were designed with widths between 1.20 m and 1.50 m, guaranteeing a minimum of 0.90 m in areas of greatest lateral constraint next to existing walls.
• Structural Paving: The roadway received a new structure composed of a wearing course (4 cm), a bonding course (6 cm), and a base course of crushed aggregate with extensive granulometry (25 cm). For the sidewalks, concrete blocks (paving stones) were chosen over a sand and cement cushion.
• Stormwater Drainage: Study of transverse and longitudinal drainage, using triangular ditches (concrete or earth) and drains with metal grates. The system was designed for a 20-year return period, ensuring the protection of the infrastructure against the effects of precipitation.
• Signage and Safety: Complete plan for horizontal and vertical code signage (0.70 m diameter), installed at a height of 2.20 m to avoid obstructing sidewalk traffic.
• Earthworks: Execution of cleaning, clearing, and stripping (0.20 m), with excavation slopes at a 1:1 inclination and fill slopes at 1:1.5.
