- Government of Meghalaya
- Three-floor State Guest House with conference hall, banquet hall, VIP suites and protocol rooms
· The brief
What we were
asked to deliver.
Taraghar is the State Guest House of the Government of Meghalaya in Shillong — a working protocol residence that hosts state guests, official delegations and government functions. TechnoGuru delivered the audio-visual, CCTV surveillance, enterprise Wi-Fi, IP-PBX telephony, addressable fire alarm, background-music PA and IT backbone scope. Seven disciplines engineered into one coordinated low-voltage layer, handed over against a documented commissioning pack in 2025.
· Engagement note
The kind of building
this actually is.
A government brief is rarely a brief about technology. It is a brief about the operating reality the building will inhabit on its busiest day — the rota, the audit, the inspection, the regulator, the family, the night shift. We engineer to that day, not to a brochure. The systems below were designed against the worst-case load and tuned to feel effortless against it for everyday use.
On a project of this type, the discipline is in the seams: where the cause-and-effect from one panel has to read cleanly into another, where the cabling pathway is shared by three trades, where the commissioning calendar needs to clear before the operator’s calendar opens. We hold all of that under one contract — design through commissioning — so that when something is asked of the building three years from now, there is one accountable hand to ask.
The scope below is the measurable output. The unwritten output is a documentation pack the operator can hand to a successor without losing a year of institutional knowledge.
· What we delivered
8 disciplines,
one contract.
A single integrated stack — design, procurement, installation, commissioning and AMC by a single accountable contractor. Each line carries its own drawing pack, cause-and-effect and commissioning sign-off.
- IP CCTV across perimeter, public areas, protocol rooms and back-of-house
- Conference-hall AV — Panasonic 2.0 mm fine-pitch LED video wall with JBL line-array audio chain
- 35 Sony 4K professional displays across protocol rooms and circulation
- Enterprise Wi-Fi 6 + Wi-Fi 5 mesh on HP Aruba Instant On
- Addressable fire-alarm system on a Honeywell single-loop panel
- Three-floor zoned background-music PA on JBL ceiling speakers
- 44 Grandstream IP phones on a Syntel Neos NexGen SIP server
- Cisco-routed IT backbone with online double-conversion UPS
· Systems integrated
The named systems,
not the trade-list.
Each system was engineered as a coordinated layer — its own controllers, commissioning report and AMC inclusion — and stitched into the cause-and-effect that runs across all of them.

- 500 m single-mode OFC backbone and 4,400 m Cat6 distribution; Netrack 22U, 17U, 9U and 6U racks for the head-end and edge cabinets
· Engineering challenges solved
The hard problems,
not the press release.
Below is what actually had to be engineered through — written by the team that solved each one, not by the team that wrote the brochure.
- 01
Sizing the conference-hall AV for both protocol-event use (head-of-state addresses, multi-language press briefings) and cultural-event use (live drum-kit and vocal performance) without specifying two parallel rigs — solved by the JBL CBT 1000 line arrays plus ASB6118 subwoofers, with the BSS BLU 100 carrying two distinct DSP presets the operator can recall in seconds.
- 02
Threading the 173-inch fine-pitch Panasonic LED wall onto a heritage-character interior without overwhelming the room — the wall sits flush in a wood-panelled recess, with line-array speakers and subwoofers visually balanced to either side and the carpet treatment absorbing first-order reflections.
- 03
Deploying 25 Wi-Fi access points across a three-floor stone-and-RCC structure where signal attenuation between zones is high — solved by AP25 (Wi-Fi 6, 4×4 MIMO) in high-density public areas and AP11 (Wi-Fi 5) in lower-density guest zones, all on a mesh backhaul with seamless roam.
- 04
Coordinating the IP-PBX endpoint mix to the guest-house workflow rather than a hotel template — pantry, bathroom and laundry get IP67-grade wet-area phones, VIP suites get four-line phones with multi-line presence, and the guardroom gets a faceplate-customisable model for departmental branding.
- 05
Holding the structured-cabling backbone to a single OFC riser strategy across three floors while leaving the architect's existing electrical-board layout untouched — RJ45 keystone terminations were brought to the existing board faceplates so no architectural finish was disturbed.
- 06
Sequencing all seven disciplines around an active protocol calendar — every cable pull, panel commissioning and amplifier alignment was scheduled around scheduled state functions, with daily site supervision to avoid noise-and-dust impact on hosted guests.
· Integration summary
How the disciplines
were stitched.
Seven disciplines engineered onto one Cat6 + single-mode OFC backbone, with the IP-PBX, CCTV head-end, Wi-Fi controller, fire-alarm panel, UPS supervisory and audio DSP all sharing a coordinated rack environment. The Honeywell fire-alarm matrix gates a documented set of outputs across PA paging, AHU response and IP-camera bookmarking, written into the cause-and-effect register and signed off by the State PWD before handover. The Panasonic LED wall and Sony display network are addressable from a single AV-control source so protocol events can be choreographed across the building's display surfaces in one cue.
· Operational impact
What changed for the
day-two team.
A handover is not a milestone — it is the day the operations team starts running the building without us. These are the changes they inherit.
- Single accountable contractor across seven disciplines for the State PWD's facility-management team — one number to call for any ELV, AV, fire or IT fault, instead of seven separate vendor relationships.
- Conference-hall AV operable by the in-house events team without an external sound engineer for routine functions — the BSS BLU 100 presets and the Soundcraft Nano M24's repeatable scene memory were designed for that.
- Wi-Fi coverage engineered for protocol-grade reliability — delegation members and visiting press get carrier-grade roaming across all three floors with no dead zones.
- Background music zoned floor-by-floor so the ambience can be modulated to the function calendar without re-cabling — the JBL Libra 300 amplifier handles routine paging suppression on the same chain.
- Configuration baselines for the fire panel, UPS, Wi-Fi controller, Cisco router, IP-PBX server and audio DSP are stored offline in our Lachit Nagar archive — any controller is recoverable from a clean slate within the same business day if a field unit is replaced.
- Documented hand-over pack delivered — as-builts, OFC test records, cause-and-effect matrix for the fire panel, fire-extinguisher schedule, IP-phone extension directory, BMS-and-AV operator manuals in plain language.
· Standards & compliance context
The codes the work
was held to.
Each standard is the framework an inspector or auditor would check our work against. Deliverables sized to satisfy each one in writing, not in conversation.
- NBC 2016 — fire and life-safety provisions for state government occupancy
- IS 2189 — code of practice for installation of automatic fire-detection and alarm systems
- IS 16102 — voice-evacuation system design and installation guidance
- TIA-568 / TIA-942 — structured cabling and telecommunications infrastructure
- IEC 60849 / EN 54-16 — sound systems for emergency purposes (international cross-reference for the PA design)
- State PWD published commissioning brief — handover format, document register and signed test records

· Why it mattered
A building is not commissioned on the day the contractor leaves. It is commissioned on the first ordinary morning the operators run it without us in the room.
We design every project with that morning in mind — the panel labelled in the operator’s own language, the documentation legible to a successor we will never meet, the AMC programme already calendared, the spares already in our Lachit Nagar office. A government engagement of this scale is judged not on handover day but in year three. That is the standard the brief was held to.
