Gurugram’s gas loads are ICU-heavy and vertical
The Gurugram hospital estate is unusual in two ways that both drive medical gas design. First, the bed mix. The city’s large private hospitals run quaternary caseloads — cardiac surgery, transplant, neurosurgery, oncology, complex critical care — which means ICU and theatre fractions well above the national average and a per-bed outlet density two to three times that of a ward-weighted hospital. Second, the buildings. Gurugram builds vertically, so a substantial share of the pipeline length sits in risers rather than in horizontal distribution.
Those two facts together mean the sizing exercise cannot be done by rule of thumb. HTM 02-01 assigns design flows per terminal type rather than per bed, and in a hospital where one ICU floor may carry forty oxygen, twenty medical air and forty vacuum terminals, a general diversity factor across the building produces a system that fails at the furthest outlet exactly when every bed is loaded. We apply diversity by department, keep it minimal in ICU, neonatal and HDU zones, and none at all to 7-bar surgical air, where each outlet draws around 350 L/min in short bursts with no meaningful coincidence benefit.
Risers, zoning and the tower problem
In a low-rise hospital the pipeline problem is horizontal distance. In a Gurugram tower it is height and shaft discipline, and that changes several decisions.
Vacuum degrades faster over vertical distance than pressure gases do, so vacuum mains get sized more generously than the arithmetic suggests. Thermal movement across twelve or more floors needs real expansion allowance and proper bracketing rather than nominal support at each slab. Zoning should follow the building rather than the org chart — an area valve service unit and alarm zone per clinical floor, positioned where nursing staff can reach them in an emergency, not tucked into a locked plant riser. Every slab penetration needs certified fire-stopping, and in a building carrying a Haryana fire scheme approval that detail gets inspected.
Terminal-unit standardisation is worth deciding early. Gurugram specifications often call for imported BS or NIST terminals over Indian equivalents; either is defensible, but mixing types across a building creates a spares problem that outlasts the project.
Source strategy for a quaternary build
Most Gurugram quaternary hospitals should be holding three independent oxygen sources under the NFPA 99 philosophy: liquid oxygen as primary with telemetry on the tank, PSA generation or a second bank as secondary, and an automatic cylinder manifold as reserve, plus an emergency supply connection point outside the building that a fire tender can actually reach. In a tower with tight boundaries and structured parking, that access point is a design-stage decision, not a commissioning-day discovery.
Medical air and vacuum plants should be duplex or triplex with automatic changeover annunciated at the master panel. Air quality is the item most often let down after commissioning — oil-free compressors, duplex desiccant dryers and multi-stage filtration delivering a pressure dew point below minus 40 degrees C, with CO, CO2 and oil content verified against pharmacopoeial limits on a defined schedule rather than only at handover. Where theatres run pneumatic tools, 7-bar surgical air needs its own compressor and receiver, not a regulator teed off the 4-bar main. AGSS runs on dedicated disposal units and separate ducting, never on the vacuum plant.
Haryana’s statutory route
PESO licensing for bulk liquid oxygen is national, and its separation distances usually constrain tank siting more than anything else on a tight Gurugram plot. Everything around it is state-specific and differs from Delhi practice. Consent to establish and consent to operate come from the Haryana State Pollution Control Board, with their own formats and processing times. Fire NOC comes from the Haryana Fire Service via the municipal corporation, and greenfield hospital buildings carry a fire scheme approval at design stage covering plant room fire rating, shaft compartmentation and penetration sealing. Building plan sanction and occupation certificate run through HSVP or the Town and Country Planning department depending on the licensing route for the parcel. Clinical registration sits with the Haryana health department.
On standards, the working stack is the same everywhere: size and test to HTM 02-01, adopt the NFPA 99 three-source and installer-qualification requirements, specify components certified to ISO 7396-1 with ISO 9170-1 terminals and ISO 5359 hoses, and document it in the format a NABH assessor expects. NABH publishes no engineering code of its own; it audits whether you can evidence design to a recognised standard.
Plant room air in the NCR
Gurugram sits in the same airshed as Delhi and sees the same severe particulate season from late October into January. The medical air plant is where that shows up. An oil-free compressor drawing NCR ambient air loads its intake filtration far faster than the same machine on the coast, and carry-over into the drying train degrades both pressure dew point and delivered air quality. Specify generous intake filtration, site the intake away from DG exhaust, service road frontage and basement ramp openings, shorten the intake filter service interval against the manufacturer’s coastal-climate assumption, and test delivered medical air quality on a schedule.
The advantage over older Delhi buildings is that Gurugram plant rooms are usually purpose-built, with real ventilation, heat rejection and maintenance access designed in — so the above is straightforward to specify rather than a compromise negotiated around an existing basement.
Delivering from Pune to Gurugram
Said plainly, because it matters on a life-support installation: RayMedico Projects has one office, in Pune — no Gurugram office, no NCR team, no permanent presence in North India. We deliver here with a deployed team, structured as follows.
- Load survey within 5 to 7 working days, mapped department by department with a ten-year growth allowance, including measured pressure at remote terminals under load where an existing system is in scope.
- Qualified brazers stationed on site for the continuous installation period, with brazing qualification records included in the handover dossier. Nitrogen-purged silver brazing throughout, with degreased medical-grade copper to EN 13348 kept capped in transit and in site storage.
- Consolidated consignments planned against the installation sequence over roughly 1,400 km and three to four days road transit, with copper quotations valid for 15 to 30 days because the material price tracks LME rates.
- An enlarged critical-spares handover — terminal cartridges by gas type, AVSU spares, alarm sensors, regulator and changeover components — sized on the assumption that replacement from Pune takes days rather than hours.
- Biomedical team training and contractual AMC response windows, covering permit-to-work discipline, alarm interpretation and first-line fault clearance. Better that your engineers can act immediately than wait on a promise we cannot keep from that distance.
Where to start
Two decisions set the budget before anything else: the outlet schedule by department, and the oxygen source strategy. Model those properly and the rest follows from arithmetic. Public-sector context matters too — PM-ABHIM funding has expanded critical care capacity across Haryana, and Ayushman Bharat and CGHS volumes raise sustained utilisation in facilities specified for lower throughput.
