1-Attachment B, WPD Parking Lot Core Thickness.pdf

This is a technical specification document for the City of Wichita's Public Works & Utilities Department supporting the 2026 Wichita Police Department Parking Lot Reconstruction project. The document outlines the core thickness requirements and pavement specifications for the parking lot reconstruction. The project involves the removal and replacement of existing asphalt pavement with specific attention to subbase preparation and compaction standards. The specifications detail the required thickness of various pavement layers, including asphalt concrete course thickness, which must meet or exceed the specifications outlined in the document to ensure proper structural integrity and longevity of the parking lot surface.

The specifications establish minimum performance standards for materials and construction methods, including requirements for compaction percentages and density testing to verify compliance with industry standards. The document provides guidance for contractors regarding the acceptable range of core thicknesses and procedures for addressing any areas that fall below minimum requirements, ensuring quality control throughout the construction process. These technical specifications are integral to the bidding process, as contractors must demonstrate their ability to meet these requirements in their proposal submissions and must comply with them during project execution.
