Key Updates in the 2018-2019 Edition

The transition from 2018 to 2019 brought significant shifts in the HVAC and plumbing sectors. Tariffs on steel and copper, along with changes in labor availability, meant that old data was suddenly obsolete. Here is what sets the 2019 edition apart.

1. Adjusted Material Costs for Volatile Markets

In 2018, the cost of copper piping and steel ductwork fluctuated wildly due to international trade policies. The 2019 estimator incorporates these spikes, providing a “worst-case scenario” baseline that protects contractors from underbidding.

• Copper Piping: Updated to reflect Q4 2018 market highs.
• HVAC Units: Adjusted for new energy efficiency standards (SEER ratings) mandated in several US states.

2. Refined Labor Hour Standards

One of the most critical aspects of Thompson’s work is the labor unit. The 2019 edition recognizes that skilled labor shortages were driving up hourly wages in major metropolitan areas like New York, San Francisco, and Chicago.

• Installation Time: Increased by approximately 5-8% for complex retrofits.
• Testing & Balancing: More rigorous time allocations for HVAC air balancing to meet modern code compliance.

3. Code Compliance Integration

The estimator doesn’t just list prices; it implicitly accounts for the time required to meet the 2018 International Plumbing Code (IPC) and International Mechanical Code (IMC) updates. This ensures that your bid includes the necessary steps for inspection approval, avoiding costly rework later.

How to Use the Estimator for Accurate Bidding: A Step-by-Step Guide

Using the 2019 National Plumbing & Hvac Estimator by James A. Thompson effectively requires a systematic approach. Follow these concrete steps to generate a winning bid.

Step 1: Define the Project Scope Clearly

Before opening the book or software, outline the exact requirements.

• Example: “Install 150 linear feet of 2-inch Type L copper pipe, 10 fixtures, and one 5-ton rooftop HVAC unit.”
• Tip: Never assume; verify blueprints against site visits.

Step 2: Extract Base Units from the Estimator

Locate the specific line items in Thompson’s guide.

• Action: Find the code for “2-inch Copper Pipe Installation.”
• Data Point: Let’s say the book lists 0.8 labor hours per foot and $12.50 per foot for materials (base national average).

Step 3: Apply Your Local City Cost Index

National averages are just a starting point. You must apply your local multiplier.

• Formula: Base Cost × City Cost Index = Local Cost
• Example: If you are working in Boston, where the index might be 1.25:
  • Labor: $0.8\text{ hours}\times 1.25=1.0\text{ hour per foot}$0.8 hours×1.25=1.0 hour per foot.
  • Material: $$$12.50 \times 1.25 = $15.62 \text{ per foot}$.

Step 4: Calculate Total Direct Costs

Multiply your adjusted units by the total quantity.

• Labor Total: $$150 \text{ ft} \times 1.0 \text{ hr/ft} \times $45/\text{hr (your wage)} = $6,750$.
• Material Total: $$150 \text{ ft} \times $15.62 = $2,343$.

Step 5: Add Overhead and Profit Margin

Never bid at cost. The estimator helps you see the direct cost, but you must add your business sustainment numbers.

• Overhead: Typically 10-15% (office rent, insurance, vehicles).
• Profit: Typically 8-12% for standard jobs.
• Final Bid Calculation: $$($6,750 + $2,343) \times 1.25 (\text{overhead}) \times 1.10 (\text{profit}) \approx $12,502$.

Pro Tip: Always round up slightly to account for unforeseen site conditions. A bid of $12,550 looks professional and provides a small buffer.

Comparison: Thompson Estimator vs. Generic Software

Many contractors wonder if they should stick to books like James A. Thompson’s guide or switch entirely to cloud-based AI software. Here is a breakdown to help you decide.

Verdict: For high-stakes commercial projects in 2019 and beyond, the depth of data in Thompson’s estimator offers a level of accuracy that generic software often misses, particularly regarding labor nuances.

Common Mistakes to Avoid When Estimating

Even with the best tools, human error can creep in. Avoid these pitfalls when using the 2019 National Plumbing & Hvac Estimator.

1. Ignoring Regional Variations: Using the national average without applying your city’s cost index is the fastest way to lose money. Labor in rural Mississippi costs significantly less than in downtown Seattle.
2. Overlooking Waste Factors: Thompson’s guides usually suggest a waste percentage (e.g., 5% for pipe, 10% for ductwork). Skipping this leads to material shortages mid-project.
3. Outdated Wage Rates: The book provides hours, not your specific wage. Ensure you update the hourly labor rate to match your current payroll, including taxes and benefits.
4. Failing to Update for 2019 Codes: If the estimator is based on 2018 data, double-check if new 2019 local ordinances require additional materials (like backflow preventers) that aren’t in the base unit.

FAQ Section

1. Is the 2019 National Plumbing & HVAC Estimator suitable for residential jobs?

Yes, absolutely. While it is robust enough for large commercial projects, the detailed breakdowns allow residential contractors to create highly precise bids for bathroom remodels, water heater replacements, and mini-split installations. The granularity helps prevent underbidding small jobs where margins are typically thinner.

2. How often does James A. Thompson update the data?

Historically, the National Estimator series is updated annually. The 2019 edition specifically captures data trends from throughout 2018 to ensure relevance for contracts signed in 2019. For the most current pricing today, users should apply current inflation multipliers to the base figures provided in the text.

3. Can I use this estimator for green building projects (LEED)?

The estimator covers standard high-efficiency units prevalent in 2018-2019. However, specialized LEED-certified materials may require manual adjustments. You can use Thompson’s labor units as a baseline but must research specific premium material costs separately, as green tech prices fluctuate faster than standard commodities.

4. Does the book include software or is it print-only?

Traditionally, the James A. Thompson National Estimator is available in both print and digital software formats. The software version allows for easier manipulation of the database and automatic calculation of city cost indices, which is highly recommended for firms handling more than 10 bids a month.

5. What if my local labor rates are higher than the national average suggested?

This is expected. The estimator provides the time required to complete a task (labor hours), not the cost of that time. You must input your specific fully-burdened labor rate (wages + taxes + insurance) into the formula. If your team is faster than the national average, you can adjust the labor hours downward, but proceed with caution to avoid quality issues.
