“Most contractors are missing out on over $200,000 per month in project contracts and they don’t even know it. They are busy, have no time for takeoffs, and they are leaving money on the table. A lot of money.
We designed our construction takeoff service with the goal of helping our clients win projects and ultimately be successful.”

WHO IS I AM BUILDERS?
I AM Builders is a National Construction Estimating Firm in the business of helping contractors win projects.
With our construction estimating and takeoff services, we’ll help you prepare a budget for your new project.
Most contractors are so busy running their job sites that they NEGLECT their bidding. You’re supervising jobs, making deliveries, going to jobsite meetings, and the only time to work on bidding is NIGHTS AND WEEKENDS.
It doesn’t have to be that way!
HOW CAN WE HELP YOU WIN MORE PROJECTS?

“I have NO TIME to estimate projects”
– Every Contractor in America
The enemy of every contractor is the lack of time. Most contractors are busy working IN the business rather than working ON the business. If that’s the case, you’re not alone. We’ve worked with over 1,400 contractors nationwide estimating and consulting, and that’s normal.
But you’ve probably tried doing it yourself, working at night after work…. probably even on the weekends on the kitchen table. We’ll find your leads for you and can even takeoff your complete construction project after so you can focus on running your business and getting your nights and weekends back.
Stop missing out on bids because of time.
You’re probably MISSING OUT on $200,000 per month because you’re busy
We did an analysis and more contractors are missing out on several projects per month that they can actually win because they are so busy they just pass them up.
Depending on what your average contract value is, most contractors are missing between $200-500K per month in sales because of being busy.
We’ll prepare your entire estimate for you so can keep bidding those jobs.



We can estimate your entire project for you based on your LOCAL PRICING so the numbers will be accurate
I AM Builders is US Based and a licensed General Contractor, so we have actual building experience.
We use a combination of a cost database and our experience to price your projects based on the zip code of your project (Note: Everyone at I AM Builders has actual field experience in construction, not just theory or “paper estimating”).
Pricing for labor and material varies by area and zip code, so we make adjustments for local labor rates, material pricing, and even look at the area’s property value to determine accurate pricing. That’s what makes our construction estimating service a great option for busy contractors.
We even back our estimates with a $1 MILLION ACCURACY GUARANTEE which covers all of our clients by our Errors and Omissions Insurance.
We can help you NEGOTIATE AND CLOSE based on proven strategies
Estimating is only a small part of what it takes to win a job. We like to see this as a TEAM EFFORT.
What do you do after the estimate to give yourself the best chance of winning? We can help you work the numbers when you’re negotiating, and even jump on a conference call with your client (as your estimating team) to help you close.
We can even advise you on EXACTLY WHAT TO DO to have them wanting to USE YOU instead of your competitor.
Over the last 10 years, and after speaking and working with THOUSANDS of Contractors, we get to see what WORKS and what DOESN’T. We have some clients landing 50% of their bids by implementing some of the strategies we can easily show you.
These aren’t strategies we made up – we listened to our clients and created our blueprint based on what they are doing right, and avoiding what they were doing wrong. Best of all….. it works for ANY CONSTRUCTION BUSINESS.

What makes a Riverside bid different
Most guys bidding in Riverside price the job and forget the City.
That’s where the money leaks. Pull up the City of Riverside Building & Safety fee schedule and read the plan check line. It says “same as Building Permit fee.” Not a percentage of it. The same number. You pay the permit, then you pay it again.
Then two more fees land on top of that doubled base. General Plan Maintenance is 10% of all plan check and permit fees. The Technology Fee is another 4%. So 14% stacked on a number that already got doubled.
Here’s what that looks like on a $700,000 job, straight off the City’s published brackets. Permit is $2,654.50. Plan check is another $2,654.50. That’s $5,309 before anything else. Add the 10% and the 4% and you’re at $6,052. Add the commercial SMIP fee at valuation times .00028, the state Building Standards fee at a dollar per $25,000, and the $30 issuance, and you land around $6,360.
Nobody publishes that number. We did the math off the City’s own schedule.
Then there’s tax. The City of Riverside runs 8.75% combined. California’s statewide floor is 7.25%. You’re a point and a half over the base on every taxable material buy inside city limits. On $250,000 of material, that’s $3,750 you didn’t have in the Fresno version of the same building.
And it isn’t one rate across the region. Jurupa Valley 92519 is listed at 7.75%. A full point under the City. If you copy your Riverside numbers into a Jurupa Valley bid, you’re going to leave a point on the table — or worse, carry a point you don’t need and lose the job over nothing.
That’s a Riverside bid. Same drywall, different arithmetic.
Four things that get missed on a Riverside construction estimate
1. Plan check as a second permit. We said it above and it’s worth saying twice, because it’s the single biggest miss we see. Most contractors carry plan check as a fraction. In Riverside it’s a duplicate. If you budgeted plan check at 30% of the permit, you’re short by roughly 70% of a permit before the job starts.
2. The 14% that rides on both lines. General Plan Maintenance and Technology aren’t charged on the permit. They’re charged on plan check *plus* permit. Estimators who catch the doubled permit still miss this one, because the fee schedule buries it under the tables.
3. The wrong tax rate for the address. 8.75% inside the City. 7.75% listed for Jurupa Valley 92519. Corona, Moreno Valley, Fontana, Ontario — check each one. Inland Empire is not a single tax jurisdiction and treating it like one costs real money on a material-heavy scope.
4. City versus County. Riverside city and unincorporated Riverside County are two different AHJs with two different fee schedules. County work goes through Riverside County TLMA. If your project is outside the city line and you priced it off the City schedule, your permit number is wrong. Not close. Wrong.
None of those four are estimating tricks. They’re just things you have to actually look up, for this city, every time. That’s what a cost estimator is for.
Riverside projects we’ve actually priced
We’re not going to show you stock photos. Every project below is a real estimate we produced. Click any one and the document opens — line items, quantities, totals. The dates are redacted and the client names were never on them. Everything else is exactly what we handed the contractor.
Full projects:
1. Ontario 5U — 91762 — $2.8M 2. Howards Murrieta — 92563 — $1.7M 3. Autozone Fontana Project — 92335 — $862K 4. FEF Riverside — 92506 — $624K
Retail and restaurant build-outs:
1. LA Fitness Corona — 92882 — $1M 2. Joann #2590, Rancho Cucamonga — 91730 — $160K 3. Angry Chickz Riverside — 92507 — $91K 4. Temecula Sky Zone — 92591 — $90K
Tenant improvements and renovations:
1. Redlands Public Market — 92374 — $727K 2. 10323 Cypress Ave TI, Riverside — 92505 — $570K 3. 4978 Walnut Ave Renovation, Chino — 91710 — $354K 4. Corona Senior Center — 92882 — $319K
Straight talk on the numbers. Inside Riverside city limits we’ve priced five jobs, $1.37 million total. That’s the honest count. Across Riverside County it’s nine more at $3.83 million, and across the San Bernardino County side it’s ten at $5.20 million. The whole Inland Empire book is 33 projects and just over $20 million.
We’re telling you the small number on purpose. Anybody can claim a thousand local projects. We’d rather show you four Riverside documents you can open and read than tell you a number you can’t check. Firm-wide, since 2016, we’ve estimated over $12 billion in projects and worked with over 3,500 contractors nationwide. The Riverside piece of that is five jobs. Both things are true.
Where we work in Riverside and the Inland Empire
The work follows the freeways, so that’s how we’ll lay it out.
Downtown and central Riverside, 92506. FEF Riverside is here — $624K, general conditions and a full sitework and demolition scope. This is the core of the city, walking distance to where the permits get pulled.
West Riverside toward La Sierra, 92505, on the 91. 10323 Cypress Ave TI, $570K. Nine divisions on that one — existing conditions, rough carpentry, roofing, doors and windows, finishes, specialties, mechanical, plumbing, electrical. A full interior rebuild of an existing building.
East Riverside, 92507 — UCR, University Avenue, Hunter Business Park. Angry Chickz Riverside, $91K. Acoustical ceiling, framing, drywall, insulation, painting. That’s the restaurant build-out zip, and it’s the same zip as the city’s main industrial park.
Out the 91 to Corona, 92882. Two jobs. LA Fitness Corona at $1M — ACT, metal framing, drywall, insulation and paint across eight pages. And Corona Senior Center at $319K, which is concrete, masonry, metal, rough carpentry, windows and finishes.
Down the 215 to Murrieta and Temecula. Howards Murrieta, 92563, $1.7M — our biggest Riverside County job, carrying rough carpentry, doors and windows, finishes, mechanical, plumbing and electrical. Temecula Sky Zone, 92591, $90K.
Up the 15 and the 10 into San Bernardino County. Ontario 5U in 91762 is the largest document on this page at $2.8M and fourteen pages — concrete, masonry, metals, wood and plastics, insulation, openings, finishes, mechanical and electrical. Autozone Fontana Project, 92335, $862K. Joann #2590 in Rancho Cucamonga, 91730, $160K. 4978 Walnut Ave Renovation in Chino, 91710, $354K. Redlands Public Market, 92374, $727K.
We also cover Moreno Valley, Jurupa Valley, Eastvale and Perris. Same freeways, same fee schedules to check, same crew doing the takeoffs.
Who our Riverside estimating service is for
You’re a general contractor or a sub. You’ve got a bid due, and the plans landed late. You don’t have a full-time estimator and you’re not about to hire one for one job.
That’s who this is for.
If you’re pricing off square-foot averages you found online, you’re going to lose the jobs you should win and win the jobs that eat you. If you’re doing takeoffs at eleven at night after running the crew all day, you’re going to miss a division and find out about it in month four.
We do the takeoff and the pricing. You get a line-item document like the twelve on this page — quantities, unit costs, labor, material, sub markup, a real total. You can hand it to the owner. You can bid off it. You can argue a change order with it.
Riverside construction estimating services from a team that reads your city’s fee schedule instead of guessing at it. Bring us the plans. We’ll tell you what the building costs and what the City costs on top of it.
Ready when you are.
