What SCIENCE AND ENGINEERING SERVICES, LLC is awarded work for
The six-digit NAICS codes recorded on these awards, ranked by dollars. The code is the buying agency's classification of the requirement — it is how the SBA decides who counts as a small business for that contract, and therefore who was eligible to compete for it. It is not a description of everything a company does.

3 of the 403 awards on file record no place of performance in the 50 states or DC — work performed overseas, in a territory, or with no location reported. Those awards are counted in the totals above and are not in this table, which is why these rows sum to fewer awards than the headline count.

Where these figures come from
- Source. Every figure on this page is public federal spending data from USAspending.gov, the federal government's official record of its own spending. Public record, free to read, with no data vendor in between. Each award below links to its own record there, so any number here can be checked against the government's own page.
- Scope. This record covers federal PRIME contract awards (award types A, B, C and D) published by USAspending.gov. It does not include subcontracts, grants, loans, state or local government work, commercial revenue, or any award outside the fiscal years loaded here. It is a slice of one company's federal contracting and not a complete business history — treat the totals as a floor.
- Identity. Awards are grouped by Unique Entity ID (E3D7U1KNNJC8), not by name, because the same company files under several spellings and unrelated companies share names. The name shown is the spelling that appears most often on these awards, reproduced as stored.
- Missing values. Where USAspending records no amount, agency, NAICS code or location, we leave it out instead of filling it in. An award with no reported amount is still counted as an award but does not enter any total or average, which is why a row's award count can outrun its dollars.
- Corrections. Federal award data is revised by the agencies that report it. If something here disagrees with the linked USAspending record, the government's record is authoritative and ours is the copy that needs fixing — the link on each award is there so you never have to take our word for it.
This page reports what the federal contract award record contains. It is not a review, a rating, a recommendation or an endorsement, and nothing here is an assessment of the company or its work. We publish it because federal award history is public record and because knowing who currently holds a contract is the single most useful thing a small business can learn before bidding against them.

It is not a review, a rating, a recommendation or an endorsement, and nothing here is an assessment of the company or its work.
- How many government contracts does SCIENCE AND ENGINEERING SERVICES, LLC have?
- 403 federal prime contract awards are on file for SCIENCE AND ENGINEERING SERVICES, LLC here. That is a count of one dataset, not of everything the company has ever done: this record covers federal PRIME contract awards (award types A, B, C and D) published by USAspending.gov. It does not include subcontracts, grants, loans, state or local government work, commercial revenue, or any award outside the fiscal years loaded here.
- Which agencies award contracts to SCIENCE AND ENGINEERING SERVICES, LLC?
- Across the awards on file, the largest total comes from Department of Defense: 401 awards worth $2,725,865,324. The buying agencies with the largest totals are listed on this page, ranked by total award dollars — that table is capped, so it is the top of the list rather than every agency on file.
- What kind of work is recorded on SCIENCE AND ENGINEERING SERVICES, LLC's federal contracts?
- Each award carries the six-digit NAICS code the buying agency used to classify the requirement. The largest by dollars on file is AIRCRAFT MANUFACTURING (NAICS 336411). That is how the government classified this work, which is not the same thing as a description of everything the company does.
- Where does SCIENCE AND ENGINEERING SERVICES, LLC perform its federal contract work?
- Place of performance is where the work happens, not where the company is headquartered. Across the awards on file, the largest share of the award dollars is performed in Alabama, with work also recorded in 17 other states.
- How can I check these figures?
- Every award listed on this page links to its own record on USAspending.gov, the federal government's official spending database. Nothing here is computed from a private data source: the figures are counts and sums over public records, and any of them can be checked against the government's own page in one click.
- How do I compete for the same kind of work?
- Award history tells you which agencies buy this work and roughly what they pay; open solicitations are what you can actually bid. BidGovContracts pulls federal SAM.gov postings and state portals into one feed and summarizes each one in plain English. You will also need an active SAM.gov registration with a UEI of your own before any federal award can be made to you.

Contractor pages are published for companies with at least 25 federal prime contract awards in this record. Below that there is too little on file to describe a business honestly, so no page is generated. Every federal award, listed here or not, remains searchable at its source on USAspending.gov.
