Capacity, not demand, is the constraint here
Lucknow sits at the end of a referral chain rather than the middle of one. Cases a district hospital in Bahraich, Gonda, Sitapur, Hardoi or Unnao cannot manage arrive here, and for interventional cardiology that catchment runs to tens of millions across central and eastern Uttar Pradesh. The public academic anchors carry an enormous share of it, while state and central health infrastructure programmes push cardiac capability outward into tier-two UP districts.
So the demand-side business case is rarely the hard part. Installed interventional capacity per head sits well below what the population implies, and a competently run programme fills. What is hard is capital discipline: building a lab that will pass a radiation survey and hold OEM environmental tolerances, without specifying a metro corporate standard the programme cannot fund. Two project types result — prescriptive public procurement against sanctioned budgets carrying utilisation deadlines, and private builds of 100 to 250 beds where the promoter will ask you, correctly, to justify every rupee.
New versus refurbished imaging, argued both ways
Imaging is 60-75 percent of the total, so this decision moves more money than everything else combined.
For refurbished. A certified system can cut the dominant line item by 55-70 percent, taking an all-in working lab from ₹3.5-5.5 crore down to ₹1.75-3 crore. For a programme proving demand rather than meeting known demand, that difference often decides whether the lab happens at all. It shortens payback and releases capital for the recovery bays and CCU beds that actually cap throughput.
Against, stated properly. Refurbished works only under conditions verified before the purchase order. The model must be AERB type-approved and from a recognised supplier. Tube hours and detector age must be documented, because the flat-panel detector is the expensive consumable nobody budgets for. There must be an OEM-backed service contract with committed parts availability and a stated support horizon — an end-of-support declaration two years in converts a bargain into a stranded asset. Dose-reduction software on current systems is not cosmetic; across thousands of cases it changes operator and patient dose. And financing terms on new equipment sometimes close much of the apparent gap.
Deciding. Project annual volume honestly and ask which side of roughly 400-600 procedures a year you land on, and how confident that number is. Below it, with uncertainty, refurbished is usually the rational entry. Above it, or where the programme is already turning cases away, new imaging with a long support horizon wins on lifetime cost. The same logic governs plane count: single-plane covers the overwhelming majority of adult cardiac work here, and biplane needs a documented paediatric, congenital, neurointervention or complex structural caseload behind it.
One caution. The shielded shell, HVAC, UPS and regulatory file do not get cheaper because the imaging did. Under-building the envelope to match a refurbished budget is the one saving that comes back.
Power reliability is a first-order design input
Elsewhere, UPS and DG sizing is a late procurement item. In Lucknow it belongs in the first design review, because grid quality and supply continuity are variable enough to shape the electrical topology.
Start from the load profile: modest continuous draw, and a cine acquisition pulling momentary demand commonly specified in the order of 100-150 kVA. The supply is sized to that peak, with cable impedance low enough to hold voltage regulation inside the OEM band during the run — a dedicated feeder, generously sized cable, frequently a dedicated transformer.
Then the resilience layer. The DG must accept the lab’s step load without a voltage dip long enough to abort an exposure, which is a question of alternator sizing and governor response, not just kVA. An online double-conversion UPS of roughly 20-60 kVA with 20-30 minutes autonomy bridges changeover. Whether the imaging chain itself sits on that UPS must be fixed early: it changes UPS sizing, battery footprint and electrical room layout. Around it sit the requirements that do not change with geography — a low-impedance earth, typically below 1 ohm, equipotential bonding consistent with what IEC 60601 assumes for Group 2 medical locations, and isolated power with a line isolation monitor so a first earth fault alarms rather than trips mid-procedure.
Shielding, rooms and the emergency pathway
Lead equivalence is calculated barrier by barrier from workload, operating kVp, distance, occupancy factor and the shielding design goal for the space beyond. Walls typically land at 1.5-2 mm Pb, rising where a barrier faces a fully occupied uncontrolled area at short distance; the control room barrier and its lead glass window are normally 2 mm Pb. In a price-sensitive market the temptation is to skip the calculation and blanket-spec 2 mm everywhere, which simultaneously overspends on the barriers facing corridors and underspends on the one facing the day-care ward. The shielding layout must be designed and submitted before civil work begins — retrofitting lead into finished walls is the most avoidable overrun available.
On space: 40-55 sq m for a workable single-plane procedure room, a 12-20 sq m control room on direct sightline, a 12-20 sq m technical room, and slab-to-slab of at least 3.4-3.6 m for a ceiling-mounted gantry. The technical room is the space most often cut on a tight budget and the wrong one to cut — it rejects 5-15 kW continuously against an OEM ambient band commonly 18-25°C with a hard throttle limit, and needs dedicated redundant cooling on essential power. The procedure room sits at 21-24°C, 40-60% RH, positive pressure and 15-20 air changes per hour of HEPA-filtered supply, with every duct crossing a lead barrier baffled on the shielding drawing rather than improvised on site.
For a lab taking emergency work the adjacency plan matters as much as the room. Patients referred from districts hours away have already consumed most of the ischaemic window, so the in-hospital segment must be short: a direct emergency-to-lab route clear of general traffic, a lift sized for trolley plus team, prep and recovery bays on the same floor, and CCU adjacency. Four to eight recovery bays at 7-9 sq m is the realistic provision.
AERB, state approvals and timeline
The AERB pathway through eLORA is, structurally: institution registration; layout approval before construction; a type-approved system from a recognised supplier; an approved Radiological Safety Officer; OEM installation and acceptance testing; QA testing and a pre-commissioning radiation survey at every barrier; then licence application. The licence is issued to the hospital, not the contractor — we prepare the submission package and coordinate the survey, but we cannot guarantee approval. RSO certification runs on fixed examination cycles and is a common reason a technically finished lab cannot yet be licensed, so enrol the nominee at design stage. AERB procedures are revised periodically; treat current eLORA guidance as authoritative and budget three to six months of regulatory lead time in parallel with construction.
Alongside sit the Uttar Pradesh requirements: clinical establishment registration, state fire service clearance, pollution control board consent, biomedical waste authorisation, and electrical inspectorate approval for HT and DG. Design targets AERB radiation protection requirements, NABH cardiac care criteria, NBC 2016, ISO 14644-1 where sterile zones apply, and IEC 60601. Programme is 16-24 weeks from order to handover for a single-plane lab in an existing shell, plus two to six weeks for a live-block retrofit.
Working in Lucknow from Pune
We have no office, branch or permanent team in Lucknow or anywhere in North India. Pune is roughly 1,400 km away and nothing about that is local. What we control is how the distance is managed: a supervisor and crew resident in the city for the full installation window rather than commuting; consolidated consignments verified against the bill of materials before despatch; an enlarged critical-spares handover covering shielding and door hardware, filter sets, sensors, UPS and control spares; documented training for your biomedical team on filter changes, differential pressure interpretation, UPS health checks and shielding integrity inspection; and AMC response stated plainly — same-working-day remote diagnostics, an engineer on site within 48-72 hours for a lab-down infrastructure fault, and preventive visits calendared a year ahead.
