DBO 01: Comprehensive Water Supply Improvement Works for Chümoukedima, Nagaland, including 5 years of O&M — design, execution, commissioning and operation/maintenance under ADB Single-Stage Two-Envelope OCB (ID N/CMK/WS/DBO - 01).
Chümoukedima Municipal area, Nagaland — 11 wards, 3 zones (Patkai College, Police Complex, NIT Campus) and 6 DMAs.
Bulk water and distribution improvements for NRW reduction and continuous “Drink from Tap” supply: check dam/weir works (~150 ML storage target), intake/desilting refurbishment, ~12 MLD WTP replacing deteriorated 15 MLD plant, raw/clear water transmission (incl. 600 mm DI), ~113 km distribution, service reservoirs, metered HSCs, SCADA/automation, landslide protection, pipe-crossing bridges, and related works.
Phase I SIP 3 months; Phase II Construction 30 months; Phase III Testing/Commissioning/Trial Run 3 months; Phase IV O&M 60 months. Entire design-build/commissioning within 36 months (incl. monsoon); total DBO 96 months.
Employer provides available designs/drawings; contractor validates, optimizes, prepares GFC drawings, conducts HSC survey and ≥20% topo/geotech verification (100% if significant errors), and obtains required clearances/permits.
5-year Operation Service of the water supply system on fixed+performance pay. KPIs: continuity (≥17 m residual pressure), NRW ≤15%, complaint redressal timelines, water quality to IS 10500. O&M rates include manpower, consumables, chemicals, spares; Employer pays electricity (except negligence penalties and 2× excess over guaranteed kWh).
CPHEEO Manual, IS 10500:2012, WHO guidance, JJM/AMRUT 2.0 alignment; mandatory PPC green cement and ≥IE3 motors; local youth/women training and absorption obligations.
Drawings (Vol III) and BOQ form an integral part of Works’ Requirements; BOQ covers survey/design, pipelines, E&M, SCADA and 5-year O&M.
The complete checklist of documents to submit — mandatory vs conditional, with any prescribed formats, proformas or annexures — plus how to submit: portal and mode, envelope/cover structure, digital signature requirements, signing and attestation rules, and physical originals with their deadline.
Single-Stage Two-Envelope electronic submission only on https://nagalandtenders.gov.in; any offline/outside-portal bid or discount is not considered. Bids must be digitally signed (Class III DSC from CCA-licensed CA).
Technical Bid and Price Bid uploaded in separate e-procurement folders. Price Bid includes BOQ rates in Excel plus Letter of Price Bid (and payment currencies / adjustment tables). Technical Bid remains the basis for qualification; Price Bid stays encrypted until financial opening.
Within 7 calendar days after scheduled bid submission deadline, deliver to Project Director, NUIDP (ITB 7.1 address): original Bid Document Fee instrument, original Bid Security BG, JV Agreement (if applicable), and Power of Attorney. Online scanned copies must match physical instruments.
Bid signed by authorized person; written confirmation = organizational document/board resolution/PoA. For JV, PoA signed by all partners. Deficient authorization cure period 14 days.
Bid language English. Bidder must click Freeze Bid; unfrozen bids are incomplete/invalid.
Every corrigendum/addendum in order — what changed (original vs amended value), its impact, and the action for the bidder — ending with the values that finally apply.
The downloaded tender package contains no corrigendum or addendum files, and the IFB states that any future corrigendum/addendum/clarification will be uploaded only on https://nagalandtenders.gov.in. Values above are as originally published on 3 August 2026.
Genuine conflicts within and across the documents (original vs corrigenda, clause vs annexure, tender document vs BOQ): both sides with citations, and which value prevails.
IFB para 7(d) points to “ITB 19.3 (Section 1)” for bid-security instruments, but ITB 19 is bid validity; bid security is ITB 20. Generic ITB 20.3 allows BG / LC / cashier’s or certified check, while project-specific BDS ITB 20.1 requires an unconditional bank guarantee on the Section 4 form only. Apply BDS ITB 20.1 (BG).
IFB 7(e) and BDS e-procurement item 30 allow only Demand Draft / Banker’s Cheque, while Section 4 checklist item 1 also lists RTGS/NEFT to “Employers Bank account given in IFB” — but the IFB does not print bank account details. Safer path: DD/Banker’s Cheque as in IFB/BDS.
BDS ITB 20.1 says submit original BG to the “Office of Employer Indicated at ITB 23.1”, but BDS ITB 23.1 only states the e-portal and deadline (no postal address). BDS ITB 11.2(g) correctly points physical originals to the ITB 7.1 Kohima address — use ITB 7.1 / IFB contact address.
Section 6 states both “approximately 8,424 metered household connections” (pp.111, 113) and “about 13,552 household connections” for ultimate 2060 population (p.113). Confirm design HSC quantity/BOQ basis before pricing.
Works narrative describes three zonal ground-level service reservoirs (GLSRs) totaling ~4,380 KL, but the same distribution subsection later refers to design capacity of OHRs and soil investigation for OHRs. Clarify reservoir type/locations with Employer/drawings/BOQ.
Contact block varies slightly: IFB para 5 “Near Secretariat Complex”; BDS/PCC “New Secretariat Road”; IFB signature block “North City Centre Building, New Secretariat Road”, all Kohima 797001. Same office family — use full North City Centre Building / New Secretariat Road address for courier.
IFB/EQC 1.4.1(b) item 2 couples PLC SCADA with WTP ≥6 MLD and ≥1 year O&M as one similar-nature requirement, while EQC 1.4.2 item 2 is a separate specialist-subcontractable SCADA requirement for urban WS including reservoirs and distribution (no WTP MLD). Treat 1.4.1(b) and 1.4.2 as distinct tests.
Only critical, tender-specific pre-bid queries that could materially change bid/no-bid, pricing, eligibility or contractual risk. Skip generic or obvious questions the documents already answer clearly.
Ask Employer to confirm whether billed HSCs are ~8,424 or ~13,552 and whether service reservoirs are GLSR or OHR (capacities/locations), and which document prevails for pricing.
Checklist allows RTGS/NEFT to an Employer bank account “given in IFB”, but IFB only specifies DD/Banker’s Cheque and prints no account/IFSC. Seek written clarification to avoid fee rejection.
Seek confirmation that only the Section 4 unconditional BG (payable at Kohima) is acceptable, given IFB’s erroneous ITB 19.3 reference and broader ITB 20.3 options.
Contract assumes site access by Commencement Date and contractor-led clearances, while works include NH-29 corridors, river crossings and landslide protection. Request current land possession, forest/utility clearance status and any excluded stretches.
Existing 15 MLD plant and Chathe source historically serve Chümoukedima and Dimapur; new scheme rebuilds dam storage and replaces treatment. Clarify water-sharing rights, interim supply obligations, and demolition/rehab boundaries of shared assets.
No tender value is published while qualification thresholds imply a large package (AACT/similar size INR 547 M). Request official estimated cost or budget range for bid/no-bid and JV sizing.
IFB/PCC state GoI “has applied for” ADB financing and payments are via GoN with no direct ADB payment. Ask current loan status and Employer cash-flow arrangements given 56-day interim payment period.
EQC allows specialist subcontractors only for 1.4.2 key activities, not for 1.4.1 size/nature value tests. Confirm no relaxation for WTP+SCADA or 62 km network experience via specialist sub.
Commercial, legal and execution risks a bidder should weigh: liquidated damages and penalties, unusual or one-sided clauses, tight timelines, and payment or security risks.
Delay damages 0.05% of Accepted Contract Amount per day, capped at 10% — material LD exposure on a 36-month hilly/monsoon programme.
5% Performance Security only fully released after 5th year O&M Completion Certificate (50/15/15/20 staged). Retention 7.5% (cap 5%) adds further cash lock during build.
30% of O&M pay is performance-linked; failure on continuity/NRW/complaints/quality cuts variable pay, and weak variable performance can zero the 70% fixed pay. NRW ≤15% and 100% quality compliance are demanding. Excess power costs recovered at 2× tariff.
10% of pipeline value paid only after commissioning and successful 3-month demonstration of NRW and pressure KPIs — cash-flow and commissioning risk.
Employer pays from GoN funds after Engineer-vetted IPC; ADB reimburses GoN later; no direct ADB payment. Interim Employer payment period 56 days. Loan is described as applied-for.
Works include check-dam reconstruction in silted Chathe River, landslide protection/micro-piling, NH-29 transmission, and flood/landslide resilience requirements — high construction and redesign risk in hilly terrain.
Contractor must obtain environment/safety clearances, implement EMP/RP measures (cost deemed included), prepare SSHSMP/SSEMP before physical works, and faces EHS non-compliance deductions (INR 25,000–50,000 per incidence bands).
PCC expands PS claims to include failure to perform any other contractual obligations — wide Employer draw rights beyond classic default events.
Despite 70% subcontracting ceiling, Quality Control during execution and O&M services cannot be subcontracted — bidder must self-perform long O&M.
Documents live 3 Aug; site visit 11 Aug; pre-bid 12 Aug; clarifications due 18 days before deadline; submission opens only 27 Aug and closes 3 Sep — short window for JV assembly, BG and site due diligence.
Contract Data sets total liability to Employer at the Accepted Contract Amount in INR.
