The National Park Service is issuing this as a market-research and acquisition-planning notice only, not as a solicitation for proposals. It is considering multiple Blanket Purchase Agreements or another multiple-award vehicle for engineering services. The contemplated vehicle may include two functional areas: building and utility facility CMR services, and transportation infrastructure CMR services. The proposed NAICS code is 541330 with a $25.5 million small business size standard. No solicitation package is currently available, and responses will not be considered offers or create a binding contract.
