TWO-LIFT FACILITY — DETAILED ADDITION FOR THE PROJECT

Summary recommendation (what to provide)

• Lift A — Passenger Lift (Public / Accessible)
  Purpose: carry guests, elders, wheelchair users, and staff between Ground, 1st, 2nd (Hall) and Roof/kitchen levels.
  Recommended capacity: 1000 kg (10–13 persons) — provides generous space for wheelchair access and stretcher if needed.

• Lift B — Service / Goods Lift (Kitchen & Logistics)
  Purpose: transport food trolleys, kitchen supplies, equipment and furniture between kitchen/dining and hall levels.
  Recommended capacity: 1000 kg (goods) or 750 kg depending on expected trolley sizes.

Both lifts should be provided with modern safety systems, VVVF drives (energy efficient), LED cabin lighting, emergency communication and basic UPS backup for door operation/emergency lighting.

Technical specifications (recommended, vendor-check required)

Passenger Lift (Lift A)

• Capacity: 1000 kg (10–13 persons)

• Cabin internal size (typical): 1600 mm (W) × 2100 mm (D) — allows wheelchair space plus attendants.

• Door clear opening: 900–1000 mm (automatic sliding)

• Speed: 1.0 – 1.6 m/s (1.0 m/s recommended for low-rise public use; 1.6 m/s if faster circulation desired)

• Drive: MRL (machine room-less) VVVF preferred (saves space) or conventional with machine room depending on architect choice

• Controls: microprocessor with soft-start/stop, LED position display, key-switch for staff, audible & visual indicators

• Safety: overspeed governor, buffers, door interlocks, emergency alarm/phone, auto-rescue (in case of mains failure)

• Fire provisions: fireman’s lift function or local code compliance (consult Fire Dept)

• Pit depth (approx): ~1200 mm (depends on vendor & model)

• Headroom (clear above topmost landing to roof slab): ~3400–3600 mm (vendor dependent)

• Finishes: stainless steel handrail, laminated paneling, anti-slip floor, LED lighting and mirror (optional)

Service / Goods Lift (Lift B)

• Capacity: 750 kg – 1000 kg (choose 1000 kg if large trolleys/plates moved)

• Cabin internal size (typical, for 1000kg): 1500 mm (W) × 2000 mm (D) or slightly larger to fit service trolleys

• Door clear opening: 1000–1200 mm (wider doors for trolleys)

• Speed: 0.6 – 1.0 m/s (goods lifts can be slower)

• Load-rated flooring (stainless steel or heavy duty floor covering)

• Drive: robust VVVF or geared traction as required

• Safety: overload cut-off, strong door interlocks, emergency stop, communication device

• Pit & headroom: similar vendor-dependent values — confirm with lift vendor

⚠️ Important: exact cabin sizes, pit and headroom, and machine-room requirements must be confirmed with the chosen lift manufacturer and must comply with your local building code / IS standards. The dimensions above are recommended typical ranges used by vendors in India — use them as a starting spec for the architect & lift vendor.

Civil & structural provisions (what the architect/contractor must deliver)

1. Lift shaft: reinforced concrete shaft sized to vendor shaft opening + clearances. Provide masonry/RC divider walls where needed.

2. Shaft rough opening (example guidance) (confirm with vendor):

   • Passenger 1000kg: Shaft internal ≈ 2200 mm (W) × 2600 mm (D) (example) — vendor will provide exact.

   • Service 1000kg: Shaft internal ≈ 2000 mm (W) × 2600 mm (D).

3. Pit: excavation to vendor-specified pit depth (approx 1200 mm) with water-proofing & drainage sump.

4. Top headroom: ensure required clear headroom (approx 3400–3600 mm) above top landing.

5. Shaft door openings: precise landing door locations and finishes.

6. Structural load: slab & beam design to suit elevator guide rails and dynamic loads (consult structural engineer).

7. Power & electrical room: dedicated DB, space for VVVF / controller in MRL position or machine room if non-MRL.

8. Service lobby & accessible landing finishes: tactile / signage and ramp-level access.

MEP / Electrical & Safety items

• Dedicated LT supply: 3-phase supply to lift control panel. Provide separate DB and MCB/isolator.

• UPS / Auto-rescue: Provide UPS (or vendor auto-rescue battery) to allow lift to reach nearest floor and open doors in case of power failure. For passenger lift, include 30–60 minutes UPS for rescue & lighting.

• Generator & transfer: ensure generator auto-start supports at least emergency lighting and lift rescue functionality.

• Fireman’s lift: coordinate with Fire Department; may require specific wiring and sign-offs.

• Telecom / intercom: cabin emergency telephone with GSM backup or building intercom.

• Lighting: in shaft access (landing) and machine room (if present).

• Drainage: pit pump if groundwater or potential water ingress.

Siting / operational suggestions (best practice)

• Passenger lift (A) — place adjacent to the main lobby/reception near the stair core for easy public use and accessibility. Ideally provide clear approach and veranda for elders.

• Service lift (B) — place near the kitchen/service core and service entry so trolleys can move easily from kitchen to hall and between floors with minimal disruption. If possible, position service lift with direct access to kitchen floor and hall service corridor.

• Separate access — avoid routing guest circulation through kitchen service routes; maintain hygiene & privacy.

• Accessibility — mark a wheelchair-priority boarding space near lift approach and allocate accessible seating in the hall near elevator entry.

Installation timeline & sequence

• Civil shaft & pit — during structural shell stage (Phase I recommended) before finishes. Delays in shaft excavation cause major rework.

• Electrical ducting & provisional wiring — during MEP rough-in stage.

• Vendor install & testing — after shaft completion and machine foundation works; vendor typically needs 4–8 weeks per elevator from delivery to commissioning (vendor-specific).

• Certification & handover — load testing and safety certificate from vendor; handover documents.

Maintenance & operations

• Annual maintenance contract (AMC) recommended from vendor: typically 5%–7% of installed cost per year (includes periodic inspection, lubrication, emergency calls).

• Spare parts & overhauls — budget separately for mid-life refurbishment (guide rail pads, door motors) every 7–10 years.

Cost estimates — conservative ranges (INR, India)

(These are indicative — final vendor quotations and site conditions will determine exact costs.)

A. Passenger Lift (1000 kg, MRL VVVF, inclusive of supply & installation)

• Supply + installation (manufacturer scope): ₹8,00,000 – ₹12,00,000

• Civil work (shaft finishing, pit waterproofing, shaft doors, structural minor works): ₹2,00,000 – ₹4,00,000

• Electrical / UPS / DB & commissioning: ₹1,00,000 – ₹2,00,000

• Total (Passenger Lift A): ₹11,00,000 – ₹18,00,000

B. Service / Goods Lift (1000 kg, heavy duty)

• Supply + installation: ₹7,00,000 – ₹11,00,000

• Civil work & shaft finishing: ₹1,50,000 – ₹3,50,000

• Electrical & commissioning: ₹80,000 – ₹1,50,000

• Total (Service Lift B): ₹9,30,000 – ₹16,00,000

C. Combined two-lift cost (installed & civil & electrical)

• Lower estimate: ~₹20.3 lakh (₹2,030,000)

• Upper estimate: ~₹34.0 lakh (₹3,400,000)

D. Contingency & approvals: add 8–10% for site variations, statutory NOCs, and unforeseen civil work.
So revised combined budget estimate: ₹22.0 lakh – ₹37.5 lakh (rounded).

E. Annual AMC (both lifts): ~₹1.1 lakh – ₹2.6 lakh / year (5–7% of installed cost combined).

Note: If a smaller capacity passenger lift is used (e.g., 630 kg) or a 750 kg service lift suffices, costs will be lower. If you choose higher-end cabin finishes or faster speeds, expect higher vendor quotes.

Where to place lift costs in the phased budget

• Recommended: Install Passenger Lift (A) in Phase I (so elders and disabled users can access hall & upper floors from day one).

• Service Lift (B) can be installed either in Phase I or Phase II depending on budget and operational needs; however, installing both in Phase I improves logistics and avoids later civil rework inside the completed finish.

• Phased budget update (example): add a Lifts row to Phase I (or split across Phase I/II) with the combined conservative cost.

Example budget insertion (simple):

• Add to Phase I: Lifts (Passenger + Service) — ₹2,200,000 – ₹3,400,000

• Update Phase I Subtotal and Project Total by adding this line and rounding totals.

New section title:

Vertical Transport — Two Lift Facility (Accessibility & Service)

Short descriptive paragraph (for donors/brief):

To ensure dignity, accessibility and efficient food/service logistics, the project includes two lifts: a passenger lift (1000 kg capacity) located at the main lobby for elders, persons with reduced mobility and general guests; and a dedicated service lift (1000 kg capacity) near the kitchen and service core for food trolleys and logistics. Both lifts will be modern VVVF drives with emergency rescue and UPS backup for safety. Estimated installed cost (civil, electrical and commissioning) for both lifts combined is ₹22.0 lakh – ₹37.5 lakh (indicative). We recommend installing the passenger lift in Phase I; the service lift may be scheduled in Phase I or Phase II depending on funding — installing both early avoids expensive retrofitting.
