About the PIU Engagement
ESIC operates one of the largest health-care infrastructure networks in India, comprising regional offices, branch offices, dispensaries, model hospitals and super-speciality hospitals. To monitor, supervise and steer the very large construction pipeline (new hospitals, hospital expansions, staff quarters, medical colleges, deposit-work projects with PSU PMCs etc.), ESIC HQ has invited a Project Implementation Unit to act as the corporation's in-house monitoring and project-management partner. The PIU works alongside the Chief Engineer's office at ESIC HQ on planning, scope review, design coordination, procurement support, monitoring of milestones, quality assurance and dispute resolution across ESIC's construction projects.
The parent PIU tender was floated earlier; this article covers the two follow-up documents now hosted on the ESIC tenders page - the formal Addendum and the Reply to pre-bid queries. Both documents form binding amendments and clarifications that bidders must incorporate before submitting their final proposal.

What These Two PDFs Mean for Bidders
The Addendum is an official amendment to the parent PIU tender. ESIC HQ typically uses an addendum to:
Extend the bid submission deadline (the listing currently shows a new last date of 01 June 2026).
Revise the Scope of Work for the PIU - addition or refinement of monitoring, quality-assurance, design-review or risk-management duties.
Update the qualifying criteria - turnover thresholds, prior PMC / PIU experience, key personnel requirements, financial ratios.
Refine the evaluation methodology - QCBS weightages between technical and financial scores, sub-criteria for technical evaluation, financial-bid scoring formula.
Update the deliverables, milestones, payment schedule, performance security clauses, exit management or data-handover obligations.
The Reply to Pre-Bid Queries is the formal documented response to questions raised by prospective bidders during the pre-bid meeting (or in writing in advance). It is essentially a question-by-question clarification: each query that ESIC chose to answer is reproduced verbatim, with ESIC HQ's formal reply right below. The reply is a binding interpretation - bidders must align their technical and financial proposals to ESIC's clarification, even where the parent NIT text appears to permit a different reading.
Who Should Act on These Documents
The Addendum and Pre-Bid Reply are relevant to any organisation that:
Has downloaded the parent PIU NIT from the CPP Portal and is preparing a proposal for the PIU engagement.
Attended the PIU pre-bid meeting at ESIC HQ in person or via video conference, or submitted pre-bid queries in writing in advance.
Already uploaded a draft proposal on the CPP Portal and now needs to incorporate the addendum changes and the pre-bid clarifications before re-uploading the final bid.
If you have downloaded an earlier copy of the parent NIT, replace it with the latest version available on the CPP Portal after applying both documents.
How to Use the Two PDFs
Log in to the Central Public Procurement Portal at https://eprocure.gov.in/eprocure/app with your registered Class III DSC.
Locate the parent PIU tender in your My Tenders folder; both the Addendum and the Reply to pre-bid queries will be linked to the same Tender ID.
Download both PDFs from the ESIC tenders page or from the CPP Portal.
First read the Reply to Pre-Bid Queries end-to-end to understand ESIC's interpretation of each ambiguous clause, then read the Addendum to apply every formal amendment.
Cross-check the revised dates, qualifying criteria, scope, evaluation methodology, deliverables, milestones, payment schedule and performance security against the version you had downloaded earlier.
Update the technical proposal - PIU organisation chart, key-personnel CVs, prior PMC / PIU project portfolio, methodology document, project plan, quality plan, risk management plan and any specific sub-criteria the Addendum has added.
Update the financial proposal - per-resource fee schedule, monthly retainer, milestone-linked payments, applicable taxes, and any escalation formula revisions called out in the Addendum.
Re-upload the revised bid on the CPP Portal before the revised cut-off (currently 01 June 2026); save the bid summary as acknowledgement.
Important Instructions
Both documents form part of the binding tender package. Bidders are deemed to have read them whether or not they download them separately; submitting a bid that ignores either document risks rejection.
In case of conflict, the later-dated document prevails - if the Reply to pre-bid queries contradicts the parent NIT, the Reply is binding for the affected clause; the Addendum, being a formal amendment, prevails over both for its scope.
Any further changes will be uploaded only on https://eprocure.gov.in/eprocure/app and https://esic.gov.in/tenders - monitor both portals till the revised cut-off.
ESIC HQ reserves the right to issue further corrigenda or addenda before the bid-opening date.
Bidders may also seek written clarifications from the Chief Engineer's office at ESIC HQ (as designated in the parent NIT) before submitting the final bid.
The PIU engagement is typically restricted to Government PSUs, autonomous bodies or organisations qualifying under GFR-2017 Rule 133(3) - private consultancy firms should verify their eligibility from the latest qualifying-criteria text in the Addendum.
Joint Ventures and Consortia, where allowed, must comply with the JV / Consortium rules in the parent NIT as refined by the Addendum.
The qualifying-criteria documents to be uploaded (financial turnover, prior project experience, key-personnel CVs, solvency certificate, integrity pact, authority letter) must be updated to reflect the latest cut-off financial year specified in the Addendum.
Common Mistakes to Avoid
Submitting on the original date: With the unified last date moved to 01 June 2026 on the ESIC tenders page, treat that as the binding deadline.
Reading only the Addendum: The Reply to pre-bid queries can change ESIC's interpretation of a clause without an explicit Addendum amendment. Both documents must be read.
Outdated key-personnel CVs: If the Addendum revises the experience or qualification cut-off for key personnel, refresh the CVs (and supporting certificates) before re-uploading.
Outdated financial turnover: If the Addendum updates the financial cut-off year, refresh the audited balance sheets, CA certificates and net-worth proofs.
Skipping the integrity pact: ESIC tenders typically mandate signed integrity pact pages; re-validate them after the addendum.
Relying on third-party summaries: Always download both PDFs from the ESIC tenders page directly; third-party summaries are not authoritative.
Final Words
The ESIC PIU Construction Project Addendum 2026 and the accompanying Reply to pre-bid queries together amend and clarify the ongoing PIU engagement tender from ESIC HQ. Bidders should download both PDFs from the ESIC tenders page, apply every change and clarification to their technical and financial proposal, and re-upload the bid on the CPP Portal before 01 June 2026.
