Staircases Pressurization System

The U.S. Department of State's Embassy in London is soliciting quotations for preventative maintenance services of the Staircase Pressurization Systems (COLT) located at 33 Nine Elms Lane, London. The contractor must maintain all system equipment in safe, reliable, and efficient operating condition in accordance with manufacturer specifications and applicable British Standards, including BS9999, BS7346-1, and BS EN 12101-6:2005. Key requirements include providing quarterly service visits (four annually), maintaining 24/7 emergency callout capability with four-hour response time for critical equipment, obtaining UK security clearance for all personnel, and demonstrating COLT-specific experience with three references and established UK business registration. The government will award the contract to the lowest priced, technically acceptable offeror based on firm fixed-price submissions, and may make an award without discussion. The deadline for submission is April 7, 2026, at 17:00 GMT, and inquiries regarding the solicitation must be submitted to procurement_box3@state.gov by close of business February 6, 2026.

This solicitation is not a small business set-away. The contract structure consists of a base year plus four option years, with the contractor required to provide four preventative maintenance visits per year during each contract period, resulting in a potential five-year engagement. Each quarterly visit must include specific activities such as annual planned preventative maintenance during the first visit, inspection works during the second and fourth visits, and pressurization testing during the third visit. The contractor must supply trip reports within five working days of each visit, maintain equipment-specific checklists, and provide annual system certification within seven days of completion. The contractor must also possess proof of relevant licenses, comprehensive insurance coverage (public and employer's liability), and demonstrate compliance with UK health and safety regulations. Place of performance is at the U.S. Embassy London in London, United Kingdom, with quotations to be submitted in British pounds including 20% VAT.
