In short
- MES tenders come from the Military Engineer Services, the construction and maintenance agency for the Army, Navy, Air Force and other defence establishments.
- MES publishes its tenders on the Defence eProcurement portal, defproc.gov.in, under the Engineer-in-Chief's Branch and its Chief Engineers, CWEs and Garrison Engineers. MES notices also appear on mes.gov.in.
- You bid online with a Class 3 DSC after enrolling on defproc.gov.in. That enrolment is separate from eprocure.gov.in and state portals, and NIC's FAQ says it doesn't charge bidders to enrol.
- MES enlists contractors by class and category. Notices name classes from SS down to E, and categories by code, such as a(i) or b(ii). Many tenders want a class at or above the one in the NIT.
- Not enlisted? Some MES tenders accept you if you show you meet the enlistment criteria for that class: completed works, turnover, solvency, working capital and no recoveries pending.
- MES enlistment also counts outside defence: when a CPWD tender is opened to other departments' contractors, MES-enlisted firms can bid up to their limit.
MES tenders are a steady source of building, electrical and maintenance work all over India, from big cantonments to small stations in border areas. This guide explains what the Military Engineer Services does, where MES tenders are published, how MES contractor enlistment and classes work, who can bid in an MES tender, and how to submit a bid on defproc.gov.in. For the wider picture of defence buying, see our defence tenders guide.
What is MES (Military Engineer Services)?
The Military Engineer Services is the engineering arm that builds and maintains works for the Army, Navy, Air Force and other defence establishments. Its work includes:
- Buildings: barracks, married quarters, offices, stores, hospitals and hangars.
- Roads and airfields inside defence stations.
- Electrical and mechanical (E/M) services: substations, LT distribution, generator sets, pumps and air conditioning.
- Water supply and sewage systems for stations.
- Furniture and other items for defence buildings.
- Maintenance: repairs and running of installations under term contracts.
You will see these units named in MES tenders:
| Name in the tender | Short form | What it is |
|---|---|---|
| Engineer-in-Chief's Branch | E-in-C's Branch | MES headquarters |
| Chief Engineer | CE | A zone, often named by command or place, such as CE (AF) Shillong |
| Commander Works Engineer | CWE | Below a CE, over several Garrison Engineers |
| Garrison Engineer | GE | The local office that runs most works and term contracts |
So a notice might read "GE (AF) Bagdogra" or "AGE E/M No. I under GE Minniebay, Port Blair". The office that floats the tender is the one you deal with for site visits, questions and payment.
Where MES tenders are published
Defence eProcurement portal (defproc.gov.in)
The Ministry of Defence's e-tendering site, defproc.gov.in, runs on NIC's GePNIC software. Most of its tenders come from MES. In the portal's organisation list, MES tenders sit under Military Engineer Services, with the CE zone shown after it. MES tender IDs carry "MES", such as 2019_MES_240325_1.
mes.gov.in
The MES website also carries notices of tender for some works. Treat it as a pointer: the bid itself goes in on defproc.gov.in, as the notice says.
GovtTenderHub
We read defproc.gov.in through the day. You can see open Defence eProcurement tenders and the MES tenders page, with filters for state, district and tender value. Searching and reading them is free.
Types of MES tenders
Most MES tenders fall into a few groups:
- Works: a new building, a road, an extension, special repairs. Usually priced against a schedule of quantities.
- Term contracts: repair and maintenance of buildings, roads or E/M installations in a station for a set period. MES notices have opened term contracts to contractors of classes SS to E.
- E/M provision and repairs: generator sets, LT lines, transformers, pumps.
- Furniture contracts.
- Small supply and service items for MES installations.
Station-level work is spread over hundreds of locations, so many contracts are small enough for local contractors.
MES contractor enlistment: classes and categories
Like CPWD, MES keeps a list of enlisted contractors. Each enlisted firm has:
- A class, which sets the size of work it can tender for. MES notices name classes running from SS at the top down to E.
- A category, which sets the type of work. Notices write categories as codes, such as a(i), a(ii) or b(ii).
An NIT states both. One MES notice asked for class SS in category a(i). Another asked for class D and above in categories a(ii) and b(ii). Match the code in your enlistment letter to the code in the NIT exactly.
What MES looks at for enlistment
MES notices list the enlistment criteria a firm must meet for a class and category:
- Completed works of a set value
- Annual turnover
- Solvency and working capital
- Immovable property or fixed assets
- Tools and plant, and an engineering establishment (qualified staff)
- No recovery outstanding with any government department, with an affidavit
- Police verification or passport details
The figures for each class are set in MES's enlistment rules, not in this guide. Ask the CE zone or CWE office you want to work with for the current rules and the application route before you apply, and keep every certificate you send.
Who can bid in an MES tender
Every NIT sets its own rules, but MES notices follow a common pattern:
- Enlisted contractors of the eligible class and category qualify, provided there are no adverse remarks against them with the competent engineer authority.
- One class below. Contractors enlisted one class below may apply. Their bids may be considered if the response from the eligible class is inadequate. In remote and difficult areas, this can go to two classes below.
- Plenty of eligible bidders. Where seven or more eligible-class contractors meet the criteria, a one-class-below applicant is generally not considered, unless it has already completed similar works satisfactorily.
- Non-enlisted contractors can take part where the NIT allows, if they meet the enlistment criteria of the class and category in question and upload the supporting documents.
Two more points from MES notices:
- EMD. Some MES notices have exempted MES-enlisted contractors from paying EMD (earnest money). Others ask everyone. Read the EMD clause of your NIT.
- Above your financial limit. If an accepted tender is above your class's financial limit, the accepting officer can ask for an additional security deposit under the contract conditions.
MES enlistment in CPWD tenders
MES enlistment is useful outside defence too. CPWD's SOPs let a regional ADG or SDG open CPWD works up to ₹50 crore to contractors enlisted with MES, the Railways, BSNL or a state PWD. When a CPWD tender is open to non-CPWD contractors, a firm enlisted with MES can bid up to the higher of its limits (CPWD Works Manual para 4.17). See our CPWD enlistment guide.
How to bid for MES tenders on defproc.gov.in
defproc.gov.in works like every other NIC portal. Our NIC bidder registration guide shows each screen; here is the short version.
- Get a Class 3 DSC with a signing certificate, in the name of the person who signs bids. See DSC for e-tender.
- Enrol with Online Bidder Enrollment on defproc.gov.in. Your login ID is an email address. Enrolment on eprocure.gov.in or a state portal doesn't work here.
- Log in and map your DSC. A new DSC can take up to 24 hours to be recognised, so do it a day early.
- Find the tender under Tenders by Organisation (Military Engineer Services) or by search, and add it to My Tenders to get its updates.
- Download the NIT and tender documents. Check the class and category, the cover-wise list of documents, the EMD and tender cost, and the critical dates.
- Upload cover 1, the technical ("T") bid. For enlisted contractors, MES notices list an application on the firm's letterhead, a valid enlistment letter, the EPF code letter, GST registration, and proof of the tender cost and EMD where they apply.
- Upload the price bid in the format the tender gives.
- Click Freeze Bid Submission and print the acknowledgement. A bid that isn't frozen isn't evaluated.
Pay any online fee or EMD at least a day before closing, and don't leave uploads to the last hour. The portal goes by its own server clock.
Documents to keep ready
- Enlistment letter with class and category (if enlisted)
- PAN, GST registration and EPF code letter
- Completion certificates and turnover statements (for non-enlisted bids)
- Solvency certificate from your bank, if asked
- Affidavit of no recovery outstanding, if asked
- Udyam certificate, if you are a micro or small enterprise
Keep scans of these ready before you open the bid screens.
Checking MES tender results
Because defproc.gov.in is a GePNIC portal, use Tenders Status with the tender ID to see the stage: technical evaluation, financial bid opening, AOC (award of contract) and so on. Results of Tenders shows awards. You don't need to log in, but you do type a CAPTCHA. Our tender status guide explains each stage.
MES work moves through many small offices, so a daily tender alert for "MES" or your station's name helps you catch new notices before they close.
Common questions
Where are MES tenders published?
On the Defence eProcurement portal, defproc.gov.in, under Military Engineer Services and its Chief Engineer zones. Some notices also appear on mes.gov.in. GovtTenderHub lists open MES tenders from defproc.gov.in on one page.
How do I get MES contractor enlistment?
MES enlists contractors by class and category, against criteria such as completed works, turnover, solvency, working capital and no recoveries pending. Ask the Chief Engineer zone or CWE office where you want to work for the current rules and application process.
Can I bid in MES tenders without enlistment?
Sometimes. Many MES tenders ask for enlistment in a set class, but some allow non-enlisted firms that prove they meet the enlistment criteria for that class and category. The NIT's eligibility clause tells you which.
What are the classes in MES enlistment?
MES notices name classes running from SS at the top down to E; one notice, for example, asked for class D and above. Each class has its own tendering limit, and categories are written as codes such as a(i) or b(ii).
Is registration on defproc.gov.in free?
NIC says it doesn't charge bidders to enrol on its portals. Tender cost and EMD, where an NIT asks for them, are separate.
Can an MES-enlisted contractor bid for CPWD work?
Yes, when the CPWD tender is opened to contractors enlisted with other departments. You can then bid up to the higher of your MES and CPWD limits.
