SHEET 01 — SERVICES

What we draw and document

Produced to the standard of a submittal your client can stamp and issue — not a first draft.

01 / CONTROL DESIGN

Control Design Diagrams

Control schematics and system architecture diagrams for AHUs, chillers, boilers and zone-level equipment — showing sequence logic, points, and device relationships clearly enough to install from.

Formats: DWG · PDF · Revit
02 / FIELD WIRING

Terminal & Wiring Diagrams

Controller terminal layouts and field wiring diagrams mapped to manufacturer submittals — sensors, actuators, VFDs and panel terminations labeled to match your points list.

Formats: DWG · PDF
03 / SUBMITTALS

Technical Submittals

Complete submittal packages assembled to spec — cut sheets, control narratives, sequence of operations and drawing sets bundled the way your reviewing engineer expects to see them.

Formats: PDF · Word
04 / POINTS DATA

Point Schedules

Full points schedules — object type, signal range, addressing and controller mapping — structured for direct import into your programming or commissioning workflow.

Formats: Excel · CSV · PDF

SHEET 02 — INDUSTRY VERTICALS

Sectors and facility types we document

From mission-critical data center uptime to cGMP cleanroom compliance, our drawings are tailored to the specific standards, tolerances, and sequence rigor of each vertical.

VERTICAL / 01

IT & Commercial Real Estate

Multi-tenant commercial towers, corporate IT campuses, and mixed-use facilities. Focus on high-density occupancy demand control ventilation (DCV), VAV terminal zoning, tenant sub-metering, and enterprise BACnet/IP network backbones.

Applications: VAV Boxes · AHUs · Tenant Metering · BACnet IP
VERTICAL / 02

Mission Critical Data Centers

Enterprise and colocation data facilities requiring 24/7/365 uninterrupted cooling. Documentation for N+1 / 2N chiller plant redundancy, primary/secondary decoupler loops, CRAH/CRAC units, and tight ASHRAE TC 9.9 thermal envelopes.

Applications: Chiller Plants · Buffer Tanks · CRAH Units · Redundancy
VERTICAL / 03

Pharma & Life Sciences

Pharmaceutical manufacturing, cleanrooms, and research laboratories. Drawings engineered for cGMP guidelines, cascade room pressurization gradients, laminar air flow hoods, HEPA filter DP sensing, and critical temperature/RH bounds.

Applications: Cleanrooms · Cascade Pressurization · HEPA DP · cGMP
VERTICAL / 04

Hospitals & Healthcare Campuses

Complex healthcare environments compliant with ASHRAE Standard 170. Documentation for operating room suites, airborne infection isolation rooms (AIIR), positive pressure protective environments, 100% outside air AHUs, and emergency power failover.

Applications: Isolation Rooms · Surgery Suites · ASHRAE 170 · 100% OA
VERTICAL / 05

Central Utility Plants (CUP) & District Energy

High-capacity district energy centers, multi-chiller plants with thermal energy storage (TES), and condensing boiler cascades. Focus on hydraulic separators, primary/secondary pumping with VFDs, and plant-wide optimization sequencing.

Applications: Multi-Chiller Plants · Boilers · Hydraulic Decoupling · VFDs
SHEET 03 — WHY SYMATRA

Designed by people who've also stood at the panel

Most drafting shops only draw. Our team has designed, programmed and commissioned BMS systems in the field — which shows up in drawings that hold up once the contractor is on site.

Commissioning-informed drawings

We know what a technician needs on-site because we've been the technician. Terminal diagrams and points schedules are built for install day, not just for review.

Built around your timeline

Clear turnaround commitments per deliverable, agreed before work starts — with status visibility so you're never chasing an update.

Standards-aware, globally

Comfortable working to ASHRAE, SMACNA and regional equivalents, and formatting to match the conventions your local reviewing authority expects.

One point of accountability

A single dedicated contact manages your project end to end, backed by our full design team — you're never left explaining your project twice.
