Contract Labour Information Management System (CLIMS):

GSECL has developed a Contract Labour Information Management System

(CLIMS) — a comprehensive digital platform designed to manage all activities

related to contract labour transparently and efficiently.

The primary objectives of CLIMS are to save time for both agencies and GSECL

personnel, to ensure full legal and regulatory compliance and to reduce the

operational burden on agencies, allowing them to focus on their core activities. To

ensure the successful implementation and operation of CLIMS, the following

guidelines are hereby issued.

1) CLIMS is a web-based system that can be accessed by agencies from any

location using a desktop, laptop, or mobile device.

2) To begin using the system, agencies must register by entering their EPO (E-

Urja Order) number. All other necessary details are automatically fetched from

the E-Urja system.

3) The issuance of gate passes for contract labour is managed entirely through

CLIMS. Agencies can generate and track gate passes within the system.

4) In order to enable gate pass issuance, agencies are required to input and

upload the necessary details of their contract labourers into the system.

5) Once the required information is submitted, the gate pass approval process is

initiated and managed through the system. The request automatically moves

through the predefined workflow levels. Agencies can monitor the real-time

status of their gate pass applications via CLIMS.

6) Upon completion of all required approvals within the system, the gate pass is

issued to the agency.

B. Attendance and wages of workers:

1) Once contract workers gate passes are approved in the system, they are

required to be registered in Bio-Metric/Face Reader Punching machines by

2) The attendance of all contract workers can be monitored and maintained

through CLIMS by contractors.

3) Access to data of Bio-Metric is given to agencies. It should be the duty of

agencies or his supervisor to ensure the supply of specified number of

manpower and to ensure their Bio-Metric punching and reporting at the

location of work.

4) Attendance register and wage register of the worker will be generated by

CLIMS from the login of agency only.

C. Compliance to various labour laws:

1) All the contractors have to comply various labour laws and they shall submit

the attached Declaration-cum Indemnity Bond before starting of work. This

Bond may also be made part of ensuing tenders/contracts.

PUR-F-10 ET-296

2) Contractors shall upload the CLIMS generated previous month attendance

sheet, wage register duly signed by workers, wage bank statement, ECR copy,

PF Challan and Remittance slip.

3) The said submitted documents in CLIMS will go to user department, after

verification of completeness of documents, user department will forward it to

HR Department for further verification and approval.

4) If the documents are complete, HR Department will approve in CLIMS and

send to Account Department for further process of bill.

5) If non-compliance is found in submitted documents, it will be returned to user

department in CLIMS with specific remarks and user department will forward

it to contractor for compliance. In such cases, 75% of the bills may be released

subject to a maximum ceiling of 20% of the contract values. Such system of

payment shall be allowed only for 3 monthly Running Accounts (RA) bills

(Maximum cumulative amount up to 20% of the contract value) of the

contractor in a period contract (AMC) of 12 months or 6 RA bills in a period

contract (BMC) of 24 months if there is non-compliance. All other RA bills and

specifically final bill shall not be processed ifthe previous & current

compliances are not made by contractor. No such relaxation will be granted for

non-periodic, one time or overhauling type contract.

D. Special Case:

In case of work order issued for expert services to PSU or OEM/OES following

procedure may be adopted.

1) If officers / specialized manpower / expert Engineers from Govt. / Semi Govt.

Companies / PSUs / OEM / OES /foreign experts are deployed for short-term,

specialized, or adhoc technical / consultancy services (e.g., commissioning.

maintenance, consultancy or inspections), concerned Engineer In-Charge (EIC)

shall certify the same.

2) The EIC must obtain following documents from the concerned Govt. / Semi

Govt. Companies / PSUs/ OEM /OES etc:

I. Declaration cum undertaking (As per Annexure A) that visiting experts

are their regular employees with documentary proof; and

II. Declaration towards compliance of applicable labour laws.
