About this file

Written by GovTribe AI · May 14, 2025

This document is a set of construction drawings for the City of Port Huron Parking Structure Repairs 2024 project, prepared by Walker Consultants. The project involves comprehensive rehabilitation of a multi-level parking structure, with detailed repair plans spanning both lower and upper levels. The drawings, dated May 23, 2024, outline extensive repair work including post-tensioned tendon repairs, concrete slab and edge repairs, traffic coating applications, masonry restoration, joint sealing, and infrastructure improvements such as removing and reinstalling parking meter posts and ADA signage.

The project scope includes specific repair techniques for concrete structural elements, including partial and full-depth concrete repairs, tendon inspection and replacement, traffic coating reapplication, tuckpointing of masonry facades, and replacement of structural components like shelf angles and lintels. The detailed drawings provide technical specifications for each repair type, indicating a comprehensive approach to restoring the parking structure's structural integrity and surface conditions. While no specific budget is mentioned in the drawings, the extensive and detailed repair plans suggest a significant investment in maintaining and upgrading the City of Port Huron's parking infrastructure.
