Okay, jumping into HVAC controls estimating is a great opportunity to leverage your industrial controls experience! You're right, the "points" system is a key element, but there's more to it than just multiplying points by a fixed rate. Here's a breakdown of how to approach HVAC controls estimating, including insights, tips, and potential software

Understanding the "Points" System and Its Limitations
What is a "Point?" In HVAC controls, a "point" represents a single input or output (I/O) signal monitored or controlled by the Building Automation System (BAS). Examples: Analog Input (AI)

Temperature sensor reading, pressure sensor reading, humidity sensor reading.

Analog Output (AO)

Valve position command, damper position command, fan speed command.

Digital Input (DI)

Fan status (on/off), pump status, alarm condition.

Digital Output (DO)

Relay to start/stop a fan, relay to open/close a damper.

Why the Point System? It provides a relatively standardized way to scale the complexity and cost of a controls system. More points generally mean more wiring, programming, and commissioning. The Pitfalls of Only Using Points



Doesn't Capture Complexity

A simple on/off fan control (2 points) is vastly different than a complex VAV box with reheat, CO2 sensing, and occupancy control (potentially 10+ points).

Doesn't Account for Physical Layout

A job with all the devices in one mechanical room is cheaper than one spread across multiple floors.

Doesn't Account for Integration Difficulty

Integrating with existing systems (older BAS, proprietary protocols) can significantly increase labor.

Doesn't Account for the Design/Engineering Time

The 'brains' behind the project.

Doesn't Account for Project Management

Managing schedules, subs, and changes.

Doesn't Account for Startup & CommissioningA Comprehensive Estimating Approach

Here's a breakdown of factors you should consider, beyond just the point count:1. Review the Drawings and Specifications (CRITICAL): Scope of Work

Precisely what is included? What is not included? (e.g., are you responsible for power wiring? Network cabling? Field devices themselves?).

Point List

Create a detailed point list from the drawings. Categorize by AI, AO, DI, DO. This is your foundation.

Sequence of Operation

Understand how the system is supposed to work. This impacts programming time.

Control Diagrams

Trace the control loops. Identify any unusual or complex logic.

Existing Conditions

Is this a new building, a retrofit, or a system expansion? Retrofits are always more expensive than new construction.

Integration Requirements

What existing systems need to be integrated with? What protocols (BACnet, Modbus, LonWorks, etc.) are involved? Is there any proprietary equipment you need to deal with? Integration is a major time suck.

Device Specifications

Note the specific types of sensors, actuators, and controllers required. This will affect material costs and potentially installation time.

Access

How easy is it to get to the control locations?

Hazardous Materials

Is there any asbestos or other hazardous materials that need to be dealt with?2.

Material Costs



Controllers/Panels

Get quotes from your preferred vendor for the main BAS controller(s) and any expansion modules. Factor in enclosure costs, DIN rail, wiring terminals, etc.

Field Devices

Price out temperature sensors, pressure sensors, flow meters, actuators, valves, dampers, etc. Use accurate pricing; HVAC control devices can vary significantly in cost.

Wiring/Cabling

Estimate the amount of wiring needed. Use your electrical estimating experience here. Consider shielded cable for sensitive signals or noisy environments.

Conduit/Raceway

If required, estimate conduit runs and fittings.

Mounting Hardware

Don't forget mounting brackets, screws, and other hardware.

Networking Equipment

Switches, routers, media converters, etc., if network integration is involved.

Software Licensing

Factor in the cost of any required software licenses (BAS software, integration tools).3.

Labor Estimation (This is Where Experience is Crucial)



Panel Installation

Estimate the time to mount the control panel, install DIN rail, wire the controller and modules, and terminate field wiring. Your industrial controls experience will be helpful here.

Field Device Installation

This is very variable. Consider:

Location

Ceiling-mounted, duct-mounted, wall-mounted?

Accessibility

Easy access, difficult access (lifts required)?

Wiring Distance

Short runs vs. long runs?

Device Type

A simple temperature sensor vs. a complex modulating valve actuator.

Wiring/Termination

Estimate the time for wiring from the controllers to the field devices. Account for pulling cable, terminating wires, and labeling. This can be a significant portion of the labor.

Programming

This is a big one! Consider:

Complexity of the Sequence of Operation

Simple on/off control vs. complex PID loops, scheduling, and energy optimization.

Integration Requirements

Integrating with other systems requires significant programming effort.

Your Programmer's Skill Level

Factor in the experience of your programmer.

Startup and Commissioning

This involves: Powering up the system. Verifying proper wiring and device operation. Calibrating sensors and actuators. Testing the sequence of operation. Troubleshooting problems. Training the building operator. This often gets overlooked.

Travel Time

Don't forget to factor in travel time to and from the job site.

Project Management

Allocate time for project management tasks (coordination with other trades, scheduling, change orders, etc.).

Supervision

Allocate time for supervision by a foreman or lead technician.4.

Overhead and Profit

Apply your standard overhead rate. Add your desired profit margin.

Tips for Pricing by Points Don't Just Use a Flat Rate

A flat rate per point is a recipe for disaster.

Develop a Range

Develop a range of rates based on complexity and project conditions. For example:

Simple Projects (New Construction, limited integration)

Lower end of the range.

Complex Projects (Retrofits, extensive integration)

Higher end of the range.

Document Your Assumptions

Clearly document the assumptions you made when estimating the job. This will help you justify your price to the customer and manage scope changes.

Track Your Time

Track your actual labor hours on each job and compare them to your estimates. This will help you refine your estimating process over time. You can use this to create your own labor units.

Get Input From Experienced Controls Technicians

Involve your technicians in the estimating process. They can provide valuable insights into the actual time required to perform the work.

Software Options Accubid/Trimble Estimation

While primarily electrical estimating software, Accubid/Trimble Estimation can be customized to include HVAC controls items. You'll need to build your own database of materials and labor units. The benefit is that you're already familiar with the platform.

QuoteSoft

QuoteSoft is a popular estimating software for mechanical and HVAC contractors. It includes features for estimating ductwork, piping, and controls.

PlanSwift

A takeoff and estimating software that can be customized for various trades, including HVAC controls. Integrates with Excel.

Excel-Based Templates

You can create your own estimating templates in Excel. This gives you the most flexibility, but it requires significant effort to set up and maintain.

Consider a "Hybrid" Approach

Use a combination of software and spreadsheets. Use a takeoff tool like Bluebeam Revu for quantity takeoffs, and then use a spreadsheet to calculate costs.

Recommendations1. Start Small

Don't take on overly complex projects at first. Focus on smaller, simpler jobs to gain experience and refine your estimating process.2.

Partner with an Experienced Controls Contractor

Consider partnering with an established HVAC controls contractor on a project. This will give you valuable experience and help you avoid costly mistakes.3.

Invest in Training

Send your technicians to training courses on HVAC controls and BAS systems.4.

Network with Other Controls Professionals

Attend industry events and join online forums to connect with other controls professionals and learn from their experiences.5.

Track EVERYTHING

Labor, materials, change orders. You'll want to know where your estimates were accurate, and where they weren't so you can adjust your future estimating.

Example Breakdown

Let's say you're estimating a project with 50 points, and it's a moderately complex retrofit in an existing building. Here's a possible breakdown (these are very rough numbers and will vary greatly): Material Costs

$5,000 - $15,000 (depending on device types and controller requirements)

Labor (Installation)

40-80 hours

Labor (Programming)

20-40 hours

Labor (Startup/Commissioning)

20-40 hours*

Labor (Project Management): 10-20 hoursYou'd then multiply the labor hours by your hourly labor rate (including burdens) to get the total labor cost. Add overhead, profit, and material costs to get the total project cost.Good luck! It's a worthwhile field to get into, but proper estimating is absolutely essential for success. Flag for review
