The Challenge

Weather kills and injures more construction workers than almost any other hazard category. OSHA reports that construction and roofing account for roughly 26% of all work-related lightning fatalities. Crane operations have mandatory wind speed limits — typically 20 to 25 mph for personnel platform lifts — that require a qualified person to monitor actual site conditions, not a regional forecast. Heat illness is the leading cause of weather-related worker death in the summer months, and OSHA’s General Duty Clause makes employers legally responsible for protecting workers from recognized hazards including lightning, heat, and high winds. Relying on a consumer weather app or a regional station miles from the job site is not a defensible safety program. cyclonePORT gives construction operations the site-specific, real-time monitoring they need to be compliant — and to prove it.

Why Construction Sites & Contractors Choose cyclonePORT

General contractors, safety managers, and site superintendents rely on cyclonePORT because it closes the gap between OSHA’s weather-related safety requirements and the tools most job sites actually use:

Crane wind speed compliance: OSHA 29 CFR 1926.1404 requires monitoring of actual wind conditions at the equipment — not a regional forecast. cyclonePORT provides continuous on-site wind speed and gust data with configurable alerts at manufacturer-specified or OSHA-threshold wind limits.
Lightning suspension protocol: OSHA’s General Duty Clause requires employers to suspend outdoor work when lightning poses an imminent hazard. cyclonePORT’s real-time lightning proximity alerts give site supervisors the documented trigger to clear workers — and the timestamped log to prove it.
Heat illness prevention: OSHA’s Heat Illness Prevention standard requires employers to monitor heat conditions and adjust work schedules accordingly. cyclonePORT’s temperature, humidity, and wet bulb readings support OSHA-compliant heat action plans for outdoor crews.
Precipitation and schedule management: Real-time rain gauge data helps project managers make weather-delay decisions, document delay events for contract claims, and coordinate concrete pours, roofing, and other weather-sensitive activities.
Timestamped incident documentation: Every sensor reading is automatically logged. If an OSHA inspection, insurance claim, or contract dispute involves weather conditions on a specific date and time, cyclonePORT’s records are your evidence.
Multi-site management: General contractors managing multiple active projects can monitor weather conditions at all sites simultaneously from one account dashboard.

01.

The Pulse of the Sky

The anemometer is the “nervous system” of our weather stations. Moving beyond old-fashioned mechanical cups, our hardware utilizes ultrasonic sensor arrays to measure the velocity and direction of the wind. By calculating the time it takes for sound pulses to travel between sensors, it provides a lag-free, high-definition map of air movement.

02.

The PTZ Observation Unit

Our PTZ units are ruggedized optical sensors designed to withstand the very conditions they are monitoring. These aren’t just for recording video; they serve as a critical layer of visual ground-truthing. When our sensors detect a change in wind speed or pressure, the PTZ camera can automatically swivel to the point of interest—allowing us to see the formation of wall clouds, debris, or precipitation in real-time.

The lens moves vertically, allowing for a look at both high-altitude cloud formations and ground-level impacts

03.

Liquid Precision:  The Smart Rain Gauge

The rain gauge is the primary component for measuring precipitation intensity and accumulation. Our systems typically utilize “Tipping Bucket” or “Optical” technology to provide high-resolution data. As droplets enter the collector, the sensor logs the volume in real-time, allowing our AI to calculate rainfall rates per minute.

04.

Resilience by Design:  The Primary Sensor Housing

The Primary Sensor Housing is the ruggedized enclosure that integrates and protects the suite of meteorological instruments. It isn’t just a box; it is a precision-engineered environment. Designed with aerodynamic stability and thermal regulation, it ensures that internal components—like barometers, data loggers, and transmission hardware—stay dry, cool, and connected even in hurricane-force winds or sub-zero blizzards.

05.

Human-Centric Heat Intelligence

The Wet Bulb Globe is the “biometric” sensor of our weather stations. It doesn’t just measure ambient air; it accounts for the three-way punch of temperature, humidity, and solar radiation. By simulating how a human being absorbs heat while sweating in direct sunlight, it provides the Wet Bulb Globe Temperature (WBGT)—the most accurate metric for predicting heat exhaustion and sunstroke.

For companies managing outdoor crews, sports events, or high-load data centers, this sensor is the definitive “go/no-go” signal for safety.

06.

The Intelligence Engine: CyclonePORT Hub

The CyclonePORT Hub is the central nervous system of our weather monitoring architecture. It serves as the high-speed bridge between raw environmental data and actionable cloud intelligence. While our sensors are busy “feeling” the storm, the Hub is busy translating those signals, encrypting the data, and ensuring it reaches our forecasting models in milliseconds—even when local power grids or traditional networks fail.

It is designed for “Edge Computing,” meaning it processes critical data locally to provide instant alerts before the information even hits the cloud.

OSHA & Industry Standards Alignment for Construction

cyclonePORT directly supports compliance with the primary OSHA standards that govern weather safety on construction sites:

OSHA 29 CFR 1926.1404/1431/1435 — Cranes and Derricks: wind speed monitoring requirements for crane assembly, hoisting personnel, and tower crane operations
OSHA General Duty Clause (Section 5(a)(1)) — employer responsibility to protect against recognized weather hazards including lightning and heat
OSHA 29 CFR 1926 Subpart CC — weather-related work suspension requirements for crane operations
OSHA Heat Illness Prevention standard — heat index monitoring and work/rest schedule adjustment for outdoor workers
ANSI/ASSP A10.28 — Work Platforms Suspended from Cranes and Derricks (environmental condition requirements)
Contractor insurance carrier requirements for documented weather monitoring and incident reporting

Common Use Cases

Crane Wind Speed Monitoring and Suspension Documentation

OSHA 1926.1404 requires a qualified person to evaluate wind conditions before and during crane operations, and to halt lifts when wind exceeds safe thresholds — generally 20 mph for personnel platform operations under 1926.1431. cyclonePORT provides continuous on-site wind speed monitoring with configurable alerts that trigger when thresholds are approached. Every reading is logged with a timestamp, creating the documentation trail that OSHA and insurance carriers require.

Lightning Safety for Open-Site Workers

On open construction sites, workers on scaffolding, rooftops, and ground-level operations are among the most exposed workers in any industry. cyclonePORT’s lightning proximity alerts — delivered simultaneously to all registered site supervisors via the RadarOmega app — give the qualified person the real-time data to order a site-wide work suspension before lightning reaches the site perimeter. The automated alert log documents the exact time of detection and notification.

Heat Illness Prevention and Work Schedule Management

During summer months, OSHA expects employers to monitor heat index conditions and adjust crew work/rest schedules accordingly. cyclonePORT’s on-site temperature, humidity, and wet bulb monitoring gives site superintendents the real-time data to implement mandatory shade breaks, hydration stops, and activity modifications before a heat-related illness occurs — and documents the conditions at each point in the shift.

Weather Delay Documentation for Contract Claims

Construction contracts typically include provisions for weather-related delays — but those provisions require documented evidence that adverse weather actually occurred at the project location on the claimed dates. cyclonePORT’s continuous timestamped sensor log provides the verifiable, site-specific weather record that supports delay claims, change orders, and liquidated damages disputes.

i One Dashboard for Every Active Site

General contractors with multiple concurrent projects can monitor real-time weather conditions at all job sites simultaneously from a single account dashboard.

When a wind event, lightning threat, or heat emergency develops at any site, all registered supervisors at that location receive simultaneous app alerts — even when the safety manager is off-site.

A county emergency management agency detected rotation

Live video feeds from cyclonePORT stations caught the storm’s development before radar confirmation. Real-time wind data and pressure readings gave forecasters the intelligence needed to issue warnings minutes earlier than traditional methods allowed.

Emergency crews coordinated faster with shared data

When the warning went out, first responders already had access to the same video feeds and sensor data as the emergency operations center. Utility crews knew exactly where to position equipment. Fire departments staged resources based on confirmed wind speeds rather than estimates.
