About this file
This is an Engineer's Estimate document for Contract No. AC8204A26 dated December 10, 2025, prepared by the Washington Suburban Sanitary Commission (WSSC) in Maryland. The project involves constructing approximately 11,000 linear feet of 1 inch through 2 inch water house connections, approximately 2,600 linear feet of 4 inch through 6 inch sewer house connections, and approximately 335 linear feet of 1 inch pressure sewer house connections for approximately 150 new service installations at various locations in Prince George's and Montgomery Counties, Maryland. The work is to be performed on an annual basis with a sealed response deadline of 2:00 pm on Tuesday, May 26, 2026, via WSSC's eProcurement Portal. The contract includes both contingent items (items 1-15) for miscellaneous site conditions such as test pits, backfill, and utility abandonments, and primary bid items (items 16-28) for the main water and sewer connection installations across various pipe sizes and road classifications.
The engineer's estimate for bid items 16 through 28 totals $6,638,220, with an expected 2-year base term value of $480,000 annually. Individual line item unit prices range from $185 to $34,500 depending on the specific work scope, pipe diameter, main size, and location classification (State/Arterial road versus non-State road). The estimate includes mobilization/demobilization costs of $1,200 and various utility connection fees ranging from $52 to $1,225 per unit for contingent work items. The pricing structure reflects differentiated costs based on whether work is performed on State/Arterial roads or non-State roads, as well as different main pipe sizes (16-inch, 20-inch, and 24-inch PCCP mains).
