About this file
This document comprises 100% Final Construction Documents (Volume 02) for the Repair Lincoln Reflecting Pool project located at the National Mall in Washington, D.C. The project is under the jurisdiction of the National Park Service, Department of the Interior, with a contract number 140P2020C0035 and PMIS 340706. The A/E (Architect/Engineer) contract number is 12/17/202540001647, with Ahmad Khan serving as the Professional Engineer from the District of Columbia.
The construction documents include detailed civil engineering drawings prepared by multiple firms: DHM Design (Denver, CO) as the prime landscape architect, WSP (Washington DC and Chicago, IL) for civil and water systems, 360 Engineering (Golden, CO) for mechanical systems, Silman (New York, NY) for structural design, and WJE Associates (Cleveland, OH) as materials specialist. The project involves comprehensive water infrastructure replacement including: approximately 1,985 linear feet of open cut construction to replace 12-inch HDPE (High-Density Polyethylene) supply and return headers with new 12-inch Class 52 cement-lined ductile iron pipe and HDPE DR-11 pipe; removal and replacement of existing water main sections totaling approximately 525 linear feet; approximately 142 linear feet of cured-in-place pipe (CIPP) repairs; pavement demolition and restoration; and permanent concrete and pavement patching. The documents specify general notes, site-specific conditions, spill prevention and response procedures, testing and inspection requirements, and detailed construction specifications for pipe trenches, valve installations, sewer main crossings, and mechanical joint connections. Total open cut construction is approximately 21,015 square feet (0.482 acres).
