Designed Services, Deliberate Results

Every facility, campus, or complex has unique cleaning requirements. Not all areas require the same frequencies or attention. CSS will partner with you to design a plan to meet your individual needs. Together we can determine where increased service levels are needed and where decreased services may be appropriate — ensuring your needs are met while the budget stays neutral from the awarded price.

🤖

Innovation & Technology

We treat every facility as a Living Facility — flexing staff to where needs are. Sensor technology determines what areas are being used, predicts service needs before a complaint. Autonomous scrubbers and sweepers produce validated trip reports and are never absent. Technology allows us to raise standards and reduce long-term costs.

Frequently Asked Questions

Straight Answers

What facility directors, procurement officers, and CFOs ask us most.

What services does Contract Service Solutions (CSS) provide?
CSS provides custodial services, facilities maintenance, and logistics contracting for large, complex, campus-type environments — federal government installations, colleges and universities, and state and local government facilities nationwide. Every program is performance-based, built on APPA cleaning standards, and backed by metrics such as ATP surface testing, slip meter testing, and indoor air quality testing.
What types of facilities does CSS specialize in?
CSS specializes in multi-building institutional campuses: federal facilities (including DOD, NASA, USDA, US Navy, US Army, US Air Force, and NATO sites), university and college campuses, and state facilities such as FDOT and municipal complexes. Specialty areas include executive offices, board rooms, auditoriums, child care centers, fitness facilities, food service areas, and secured or escorted government spaces.
What are APPA cleaning standards, and does CSS use them?
APPA (the association for educational facilities professionals) defines five measurable levels of cleanliness, from Level 1 "Orderly Spotlessness" to Level 5 "Unkempt Neglect," along with production rates for staffing. CSS builds every custodial program on APPA standards, using a bottoms-up work-loading analysis so that staffing levels are engineered to the service level each space actually requires — not guessed. Read our full explainer: APPA Cleaning Levels Explained.
How does CSS use AI, sensors, and autonomous equipment?
CSS treats every building as a "Living Facility." Occupancy and usage sensors identify which restrooms, conference rooms, and transient spaces are actually being used so staffing flexes to real demand. Autonomous scrubbers and sweepers deliver validated trip reports and consistent results, while AI supports scheduling, reporting, and quality assessments. The result is a program that gets more reliable and more transparent every year — without the client having to ask.
What is an open-book custodial contract?
In an open-book contract, the client sees all effort and associated costs — labor hours, supplies, equipment, and management — with no hidden margins. CSS proposes open-book structures because they align both parties around outcomes instead of change orders, and they make it possible to redesign service levels mid-contract while keeping the budget neutral to the awarded price.
Is CSS a certified small business?
Yes. CSS is a certified Small Business Enterprise (SBE), which can help public institutions and prime contractors meet small-business participation goals while working with a firm whose average management experience exceeds 20 years.
