Cascade Industrial Builders is pleased to submit this Guaranteed Maximum Price (GMP) Proposal for the tenant improvement of the interior renovation of Sulphur Springs Public Library, located at 611 N. Davis Street, Sulphur Springs, Washington. This proposal is submitted in response to the invitation issued by Friends of the Library Inc. on June 4, 2026, and reflects the project scope described in the 100% Schematic Design documents prepared by Lone Star Design Group, dated June 10, 2026.

Relationship Note: Cascade Industrial Builders successfully completed Sulphur Springs Library Phase 1 (Floors 7–10) for Friends of the Library Inc. in Q4 2025, delivering on schedule and within budget. This proposal reflects our continued commitment to Friends of the Library's portfolio and our deep familiarity with building systems, base building MEP coordination, and the delivery team that made Phase 1 a success.

Why Cascade Industrial Builders
Proven Performance · Sulphur Springs Library Portfolio

Cascade Industrial Builders brings three distinct competitive advantages to Sulphur Springs Public Library: proven familiarity with this specific building and its base building systems from Phase 1, a demonstrated track record of on-time and on-budget delivery for Friends of the Library, and the AIC preconstruction intelligence platform that allows us to estimate with greater accuracy, flag risks earlier, and deliver a more transparent and auditable GMP than any competitor.

We are not simply bidding a job — we are continuing a relationship. The Phase 1 team, including Superintendent Marcus Thompson and MEP subcontractor Greenleaf Mechanical Electric, is available and committed to Phase 2. There is zero learning curve on base building coordination. We know where the conflicts are, we know the building engineer, and we know how to manage three floors of occupied public-building renovation in the heart of Sulphur Springs's CBD.

Our preconstruction analysis, supported by the AIC Franklin agent, identified the schedule risk as the single highest-priority concern on this project. We have already taken steps to address it: we have Greenleaf's PM committed to a July 14 mobilization, and we are in active discussions with a second millwork source as a contingency. We tell you this before you ask because we believe transparency is what builds durable relationships.
