Sample Sheets
Specimen drawings you can open and zoom
19 illustrative TechMEPi sheets across 9 disciplines, drawn exactly the way we issue them: title block, revision history, legend, general notes and calculated sizes. These are specimens, not project drawings — every sheet is drawn on a neutral reference building, watermarked and marked sample / not for construction.
Sample drawings
Specimen sheets on a neutral reference building. Published, watermarked, and safe to share — they show the standard of output without exposing anyone’s scheme.
Our project drawings
The real deliverable: a numbered, revision-controlled and signed drawing set issued to you in stages. Client drawings stay confidential and are never published here.

Showing all 19 sheets
Water & Plumbing
Cold and hot water distribution, storage, boosting and treatment — sized by calculation, not by rule of thumb.
Cold & Hot Water Layout
Ground floor · pipework, risers and fixture distribution
Cold and hot water distribution set out room by room — mains entry, isolating valves, a zoned riser, a 300 L cylinder and a pumped hot-water return. Pipe sizes are calculated by the loading-unit method, not assumed.
Water Storage, Booster & Riser Schematic
Break tank · transfer pumps · three-zone down service
The sheet that answers "will there be water on the top floor and will it burst a tap on the ground floor". A 45 m³ break tank, duty/standby transfer pumps, roof storage and three pressure zones with reducing valves so no outlet exceeds 3.5 bar.
RO Water Treatment — Process Flow
Pre-treatment · membrane array · disinfection
A borehole at 1 850 mg/l TDS turned into drinking water at under 60 mg/l. Twelve process stages with instrumentation, target water quality, membrane data and a concentrate stream reused for irrigation instead of dumped to sewer.
Drainage & Wastewater
Foul and surface water above and below ground, attenuation, and on-site treatment where there is no trunk sewer.
Foul Sewer Layout & Sections
Soil & vent stack · manhole run · invert levels
A longitudinal section paired with the matching below-ground plan. Every manhole carries a cover and invert level, every run carries its fall — the detail a contractor actually needs to dig to.
Storm Water & Roof Drainage
Roof outlets · catchpits · attenuation & outfall
Roof plan and site plan on one sheet, sized on a 75 mm/h design storm. Falls, outlets, overflow weirs, catchpits with silt sumps and 36 m³ of attenuation limiting discharge to the greenfield rate the county will accept.
Sewage Treatment Plant
Process flow diagram & tank section
An extended-aeration package plant for 180 population equivalent — screening through to disinfection and reuse — with the tank section that shows the diffuser grid, sludge hopper and water levels a builder has to construct to.
HVAC & Ventilation
Ventilation, chilled water and refrigerant systems — drawn as coordinated systems, not as scattered symbols.
HVAC Ventilation Layout
Ground floor · ductwork, diffusers and plant
Supply, return, extract and outside air drawn as four distinct systems, with an air-terminal schedule, volume-control and fire dampers at every compartment line, and design flow rates called up at each terminal.
Chilled Water Plant Schematic
Chillers · low-loss header · variable-flow distribution
Two 450 kW chillers on N+1, constant-volume primary, variable secondary through two-port valves, and the ancillaries most schematics forget — pressurisation, expansion, dosing and air/dirt separation.
VRF Refrigerant & Indoor Unit Layout
Ground floor · branch tree, pipe sizes & condensate
Five indoor units on one branch tree with refnet joints, liquid and gas line sizes, condensate falls and traps — plus the pipe-run and level-difference checks that decide whether the system will actually perform.
Fire Protection
Coverage studies, wet risers, pump rooms, sprinklers, detection and alarm — proven hydraulically before issue.
Fire Protection Layout
Hose-reel coverage · wet riser · detection & alarm
A coverage study, not a symbol drop. Hose-reel positions are proven with 6 m hose plus 6 m jet radii until every point of the floor is reachable, then backed by the wet riser, landing valve, detection and escape route.
Wet Riser & Fire Pump Schematic
Tank · duty / standby / jockey pumps · landing valves
The pump room and the riser it feeds, on one sheet. A dedicated 45 m³ tank, electric duty and diesel standby pumps at 1 800 l/min, a jockey pump, test line, landing valve at every floor, sprinkler control valve set and breeching inlet.
Electrical & Data
Final circuits, distribution, single-line diagrams and containment, with volt drop and discrimination verified.
Power, Lighting & Data Layout
Ground floor · final circuits and distribution
Small power, lighting and Cat6A data on one coordinated sheet, with distribution boards, an extract of the circuit schedule, segregated containment and the main earthing conductor shown explicitly.
LV Single-Line Diagram
Main panel · generator & ATS · essential distribution
Utility transformer to final board on one page: an 800 A main busbar with nine outgoing ways, power factor correction, a 250 kVA generator on automatic changeover and a separately fed essential busbar — with the fire pump taken ahead of the main isolator.
Renewable & Standby Power
Solar PV, storage, generators and changeover — engineered for the grid you actually have, not an ideal one.
Solar PV & Standby Power Schematic
13.2 kWp array · hybrid inverter · battery & generator
A grid-tied hybrid system with 20 kWh of storage, sized to the daytime base load rather than to the roof area — with the DC protection, anti-islanding, export limiting and generator interlock that make it licensable and safe.
Specialist Systems
Medical gases, LPG, pools and process systems — life-safety and hygiene-critical work with its own rulebook.
Medical Gas Pipeline Layout
Manifold room · risers · AVSUs · bed-head terminal units
Oxygen, nitrous oxide, medical air, vacuum and scavenging from manifold room to bed head — with duplex plant, compartmented risers, lockable area valve service units, area alarms and the terminal-unit arrangement at each bed.
Swimming Pool Plant Schematic
Balance tank · filtration · heating · disinfection
A 400 m³ deck-level pool on a four-hour turnover: balance tank, hair and lint strainer, duty/standby circulation, two sand filters at 25 m/h, plate heat exchanger, UV and dosing interlocked with proven flow.
BIM Coordination
Federated models, clash-free sections and plant room layouts where every clearance is dimensioned.
BIM Services Coordination
Building section · riser shaft and ceiling-void zoning
The sheet that stops services fighting each other on site: a federated section showing the riser shaft, every discipline zoned through a 900 mm ceiling void, and an enlarged detail proving the clearances.
Plant Room Coordinated Layout
Plan & section · clearances and service zoning
Equipment footprints taken straight from the federated model, every maintenance clearance dashed and dimensioned — including the 3.2 m chiller tube-pull space that gets forgotten until the first tube change.
Typical Details
The standard details a contractor is actually held to — supports, fire-stopping, sleeves and access.
Typical Installation Details
Supports · fire-stopping · chambers · access · isolation
Six standard details issued with every discipline package — pipe support and vibration isolation, fire-stopping at a penetration, inspection chamber section, AHU flexible connection, slab sleeve and pump inertia base.
No sheets match that combination.
Issued With Every Package
A drawing is never issued on its own
Each discipline ships with the calculations and schedules that prove the drawing — the paperwork an approving authority, a main contractor and a facilities team all ask for.
