The Biggest Cost Drivers in MEP Estimates | Texas Guide

Ask ten owners in Texas where their construction budget went sideways, and a large share of them will point at the same place: the mechanical, electrical, and plumbing scope. MEP work is rarely the largest package by drawing count, but it is almost always the package with the most moving parts, the longest procurement tail, and the widest spread between an early conceptual number and a final buyout. Understanding the biggest cost drivers in MEP estimates is the difference between a budget that holds through construction and one that quietly bleeds through change orders.

This guide breaks down the components that most influence MEP budgets, why they behave the way they do, and how those pressures shift as you move from Harris County to Travis County to the Permian Basin. Texas is not one construction market. It is a collection of very different climate zones, utility territories, permitting authorities, and labor pools stitched together under one state, and an MEP estimate that ignores those differences is an estimate that will be corrected later, at a worse price.

Whether you are an owner testing feasibility, a general contractor assembling a hard bid, a developer underwriting a pro forma, or a subcontractor sanity-checking your own numbers, the goal here is the same: know which line items actually move the needle so you can spend your attention where it pays.

What an MEP Estimate Actually Covers

Before you can rank cost drivers, it helps to agree on the boundaries. In most Texas commercial and institutional projects, an MEP estimate spans several CSI divisions, and the exact split changes depending on how the general contractor buys the work.

• Division 21 — Fire Suppression: wet and dry sprinkler systems, standpipes, fire pumps, pre-action systems for data and archive rooms, and clean agent suppression.
• Division 22 — Plumbing: domestic hot and cold water, sanitary waste and vent, storm drainage, natural gas, water heating, fixtures and trim, medical gas in healthcare, and grease waste in food service.
• Division 23 — HVAC: air handling units, rooftop units, chillers, boilers, VRF systems, split systems, ductwork, piping, insulation, dampers, diffusers, exhaust, and test and balance.
• Division 26 — Electrical: utility service, switchgear, transformers, panelboards, feeders, branch wiring, lighting, lighting controls, generators, and transfer switches.
• Division 27 — Communications: structured cabling, data rooms, pathways, wireless infrastructure, and audiovisual backbone.
• Division 28 — Electronic Safety & Security: fire alarm, access control, surveillance, and mass notification.

Across a broad sample of Texas projects, the MEP package commonly lands somewhere between fifteen and forty percent of total construction cost. Warehouse and shell work sits at the low end. Office and retail interiors sit in the middle. Hospitals, laboratories, central plants, semiconductor support facilities, and data centers push toward the high end and occasionally past it. The wider the range for your building type, the more a disciplined mechanical electrical plumbing takeoff is worth.

Why MEP Line Items Swing More Than the Rest of the Budget

Structural steel is priced against tonnage. Concrete is priced against cubic yards. Both are relatively stable relationships between a quantity and a dollar figure. MEP does not behave that way, and there are four structural reasons why.

• It is engineered, not just measured. A duct main is not simply a length of metal. Its size follows from a cooling load calculation, which follows from envelope performance, occupancy density, ventilation rates, and outdoor design conditions. Change any input and the quantity changes.
• It is procurement-heavy. Major equipment carries lead times measured in months, sometimes past a year. Anything with a long lead time is exposed to escalation, storage costs, and schedule pressure.
• It is coordination-dependent. MEP trades share the same ceiling cavity, shaft, and chase. When space is tight, labor productivity drops even though the quantity of material never changed.
• It is code-sensitive. Energy code, ventilation code, and local amendments directly dictate equipment efficiency, control complexity, and commissioning scope. These are not preferences. They are enforceable requirements that carry real dollars.

Those four traits are why two estimators can look at the same schematic set and produce numbers twenty percent apart. They are also why the drivers below deserve individual attention.

1. HVAC Equipment Selection and Cooling Load

In a cooling-dominated state, HVAC is usually the single largest cost driver inside the MEP budget. Texas sits across ASHRAE climate zones 2A, 3A, 3B, and 4B, which means the same building program produces meaningfully different tonnage depending on where it lands.

Along the Gulf Coast — Harris County, Galveston County, Brazoria County, Jefferson County, and Nueces County — latent load is the story. High humidity drives dehumidification requirements, larger coils, dedicated outdoor air systems, and more attention to reheat. In West Texas and the Panhandle — El Paso County, Midland County, Ector County, Lubbock County, Potter County, and Randall County — sensible load and dry-bulb design temperatures dominate, evaporative strategies become viable, and moisture control is a far smaller line item. Central Texas markets such as Travis County, Williamson County, and Hays County fall between the two, with a shoulder season long enough to make economizer and control strategies genuinely valuable.

What moves the number

• System type: packaged rooftop units versus split systems versus VRF versus a central chilled water plant. The delta between these options on a mid-size building can exceed the cost of the entire plumbing package.
• Installed tonnage and the safety factor baked into the load calculation. Oversizing is one of the most common and most expensive design habits.
• Efficiency tier. Higher SEER2, IEER, and kW-per-ton targets carry a first-cost premium that must be weighed against operating savings.
• Redundancy. N+1 in a data hall, surgery suite, or lab is a multiplier, not a rounding error.
• Ductwork scope. Sheet metal takeoff quantities, gauge, seam type, liner versus wrap, and the ratio of rectangular to round all shift both material and labor hours.
• Controls. A basic thermostat network and a full direct digital control system with graphics, trending, and integration are not comparable scopes.

A practical note for anyone reviewing an early estimate: ask what outdoor design conditions were used and whether the tonnage came from an actual load calculation or a square-foot rule of thumb. In Bexar County or Hidalgo County, a rule of thumb borrowed from a cooler market will understate the plant every time.

2. Electrical Service Capacity, Switchgear, and Distribution

Electrical is usually the second heaviest driver, and on technology-forward projects it takes first place outright. The controlling question is deceptively simple: how much power does the building need, and how hard is it to get that power to the building?

Service size drives everything downstream. A 1,200-amp service and a 4,000-amp service do not just differ in gear cost; they differ in transformer requirements, feeder sizes, conduit runs, pad and vault work, and utility coordination effort. Utility territory matters as well. Projects in the Dallas-Fort Worth area coordinate with Oncor across Dallas County, Tarrant County, Collin County, and Denton County. Greater Houston works through CenterPoint Energy in Harris County, Fort Bend County, and Montgomery County. Austin Energy serves much of Travis County, CPS Energy serves Bexar County, and El Paso Electric serves El Paso County. Each has its own application process, design review timeline, and cost-sharing rules, and each of those can quietly add weeks and dollars.

Where electrical budgets escalate

• Switchgear and switchboards, which have carried some of the longest lead times of any construction commodity in recent years.
• Copper. Conduit and wire pricing tracks commodity markets closely, and long feeder runs in large-footprint buildings amplify the exposure.
• Standby and emergency power. Generators, automatic transfer switches, fuel storage, sound attenuation, and load bank testing form a package that is easy to underestimate.
• Lighting and lighting controls. Fixture counts are straightforward; networked controls, daylight harvesting, and code-required commissioning are not.
• Equipment connections. Kitchen equipment, process equipment, and specialty loads carry a surprising amount of hidden labor.

3. Plumbing Systems and Underground Utilities

Plumbing rarely tops the MEP budget, but it produces some of the largest percentage overruns because so much of the risk sits below grade where the drawings are least detailed.

Above grade, the drivers are fixture count, fixture quality tier, water heating strategy, and riser routing. A building with distributed restroom cores costs more to pipe than one with stacked cores, even at identical fixture counts. Below grade, the drivers are soil, water table, depth, and distance to the point of connection.

Texas geology makes this regional. Expansive clay across Dallas County, Tarrant County, and Collin County affects bedding, backfill, and long-term movement. A high water table across much of Harris County, Fort Bend County, Galveston County, and Jefferson County means dewatering and shoring can appear in a scope that looked simple on paper. Rocky conditions in the Hill Country — Travis County, Hays County, Comal County, and Bexar County — can turn routine trenching into rock excavation. Long runs to the main in unincorporated areas of Montgomery County, Parker County, or Kaufman County add pipe, restoration, and sometimes a lift station.

Specialty plumbing that changes the math

• Medical gas systems in healthcare, which require certified installers, brazing procedures, and third-party verification.
• Grease waste, interceptors, and acid waste in food service, labs, and education facilities.
• Rainwater harvesting and condensate recovery, which appear frequently on Austin-area projects pursuing green building credits.
• Backflow prevention, booster pumps, and pressure zoning in taller buildings.

4. Labor Rates, Productivity, and Crew Availability

Material gets the headlines; labor decides the outcome. On a typical Texas MEP package, labor accounts for roughly forty to sixty percent of installed cost, and it is the component most sensitive to factors that never appear on a drawing.

Rates vary across the state. Metropolitan markets in Dallas County, Tarrant County, Harris County, Travis County, and Bexar County generally carry higher base rates than rural counties, but rural work often carries travel, per diem, and mobilization that erases the gap. Energy-sector demand in Midland County, Ector County, Reeves County, and Webb County periodically pulls skilled electricians and pipefitters away from commercial construction, and when that happens, pricing in those counties can exceed major metros. Public work adds another layer: projects subject to prevailing wage or Davis-Bacon determinations are priced against published rates rather than market rates.

The productivity factors estimators actually apply

• Working height. Anything above roughly fourteen feet introduces lift time and reduces installation rate.
• Congestion. Dense overhead coordination in a hospital corridor or lab can cut productivity by a third against an open warehouse.
• Occupied or phased work. Renovations in an operating facility carry after-hours premiums, infection control barriers, and repeated setup and teardown.
• Schedule compression. Overtime and second shift raise cost per hour while lowering output per hour — the worst combination.
• Weather exposure. Summer heat on Gulf Coast and South Texas sites in Cameron County, Hidalgo County, and Nueces County genuinely reduces sustained output for roof and exterior work.

5. Material Price Volatility and Escalation

An MEP estimate is a snapshot. The question is how long that snapshot stays accurate. Copper, aluminum, steel, resin-based products, and electronic components have all shown enough movement in recent years that a number carried without an escalation allowance is a number that expires.

Copper matters most because it appears everywhere: branch wiring, feeders, refrigerant piping, domestic water piping in many designs, and grounding. Sheet metal pricing tracks steel. PVC and CPVC track resin and petrochemical feedstock, which has an additional Texas wrinkle — a meaningful share of national capacity sits along the Gulf Coast in Harris County, Brazoria County, and Jefferson County, so regional weather events can influence national pricing.

Good practice is straightforward: record the pricing date on every estimate, note how long vendor quotes remain valid, and carry an explicit escalation line to the projected midpoint of construction rather than pretending today’s price will hold.

6. Equipment Lead Times and Procurement Strategy

Lead time is a cost driver disguised as a schedule item. When switchgear, generators, chillers, or large air handling units cannot arrive when needed, the project pays in one of three ways: it accepts a more expensive expedited option, it pays extended general conditions while waiting, or it redesigns around available equipment.

This is why sophisticated owners in fast-moving submarkets — Collin County and Denton County in North Texas, Williamson County north of Austin, Comal County and Guadalupe County along the I-35 corridor — increasingly separate long-lead equipment into an early procurement package. Doing so locks pricing, protects the schedule, and converts an unpredictable risk into a known cost. It does introduce storage, insurance, and handling costs, which the estimate must capture rather than ignore.

7. Building Type, Occupancy, and Program

Nothing predicts MEP cost per square foot better than what the building does for a living. Two structures of identical size and identical shell can differ by a factor of five in MEP intensity.

Facility Type	MEP Intensity	What Drives It
Warehouse / distribution	Low	Minimal conditioning, high-bay lighting, basic sprinkler and restroom cores
Office / corporate interiors	Moderate	Zoning density, ceiling coordination, lighting controls, tenant flexibility
Retail / restaurant	Moderate to high	Kitchen exhaust, make-up air, grease waste, heavy equipment connections
K-12 and higher education	Moderate to high	Ventilation rates, acoustics, controls, security and communications scope
Multifamily	Moderate	Repetitive unit rough-in, risers, metering, corridor pressurization
Healthcare / surgical	High	Air change rates, pressure relationships, medical gas, redundancy, commissioning
Laboratory / cleanroom	High	Fume hood exhaust, process piping, precise control, filtration
Data center	Very high	Cooling density, power redundancy, monitoring, testing and validation

The practical lesson is that benchmarks only work within a category. Applying an office cost per square foot to a medical office building, or a warehouse benchmark to a cold storage facility in Hidalgo County, produces a number that feels reassuring and is simply wrong.

8. Design Completeness and Documentation Quality

The accuracy of any estimate is capped by the quality of the information behind it. Industry practice recognizes distinct estimate classes, and each carries a different expected range.

• Conceptual / order-of-magnitude: produced from program area and building type. Expect a wide band and heavy reliance on benchmarks.
• Schematic design: systems chosen but not sized in detail. Equipment allowances still carry meaningful uncertainty.
• Design development: equipment schedules and single-line diagrams exist. This is where a real MEP quantity takeoff begins to add value.
• Construction documents: fully coordinated and permit-ready. Quantities are measurable and the estimate becomes a bid-quality document.

Incomplete documentation does not remove cost; it relocates it. Gaps become assumptions, assumptions become allowances, and allowances that were set too low become change orders. Any credible MEP estimate should include a written list of inclusions, exclusions, allowances, and assumptions. If a proposal lacks that list, the number is less meaningful than it appears.

9. Energy Code, Ventilation Standards, and Local Amendments

Texas adopts statewide energy code requirements administered through the State Energy Conservation Office, with commercial construction generally following the International Energy Conservation Code and ASHRAE Standard 90.1. What complicates estimating is that home-rule cities routinely adopt local amendments, and jurisdictions do not move in lockstep.

Austin, in Travis County, has historically pursued stricter energy and green building requirements than the state baseline. Houston, Dallas, San Antonio, Fort Worth, El Paso, and Plano each maintain their own amendment sets and review practices. Move a project a few miles across a jurisdictional line — from the City of Dallas into unincorporated Dallas County, or from Houston into an unincorporated pocket of Harris County or Montgomery County — and the applicable requirements, plan review process, and inspection regime can all change.

Code-driven scope that carries real dollars

• Equipment efficiency minimums that push selections into a higher-cost tier.
• Economizer requirements on units above a capacity threshold.
• Demand-control ventilation, occupancy sensing, and automatic receptacle control.
• Duct and pipe insulation levels, plus leakage testing.
• Lighting power density limits and mandatory control zoning.
• Building commissioning, which becomes mandatory above certain thresholds and is a distinct line item, not an afterthought.

10. Coordination, Congestion, and Constructability

Two projects can carry identical quantities of duct, pipe, and conduit and still differ substantially in installed cost, because the space they must occupy is not the same. Available plenum depth, structural depth, shaft sizing, and slab-to-slab height determine how many times a trade must offset, re-hang, or work around another trade.

This is where BIM clash detection and coordinated MEP drawings pay for themselves. Resolving conflicts in a model costs modeling hours. Resolving them in the field costs rework, delay, and RFI cycles. Prefabrication — rack assemblies, multi-trade corridor modules, unit rough-in assemblies for multifamily projects in Bexar County or Tarrant County — moves labor into a controlled shop environment and typically improves both cost and schedule certainty.

Hangers, supports, and seismic or wind bracing deserve their own mention. They are unglamorous, frequently under-quantified, and on a large project they add up quickly.

11. Permits, Impact Fees, and Utility Coordination

Soft costs attached to MEP scope are easy to overlook and rarely small. Plan review fees, permit fees, water and sewer tap fees, impact fees, and utility contribution charges vary widely across Texas jurisdictions and can differ dramatically between a city and the unincorporated county surrounding it.

Fast-growing suburban jurisdictions in Collin County, Denton County, Williamson County, Fort Bend County, and Comal County frequently levy impact fees to fund infrastructure expansion. Municipal utility districts across Fort Bend County, Montgomery County, and Harris County add another layer of authority with its own connection requirements. Third-party plan review and inspection, common where municipal departments are backlogged, is another line that belongs in the estimate rather than in a surprise invoice.

12. Site Conditions, Climate, and Resilience Requirements

Texas asks its buildings to survive a wide range of conditions, and resilience is a cost driver with a clear geographic pattern.

• Coastal wind and flood zones: Galveston County, Nueces County, Cameron County, Aransas County, Brazoria County, and Jefferson County require wind-rated equipment, engineered anchorage, protection against wind-borne debris, and frequently elevated placement of mechanical and electrical equipment above design flood elevation. Elevating a generator or switchgear is a structural and electrical cost, not merely a location preference.
• Freeze protection: statewide attention to cold-weather resilience has increased significantly. Heat tracing, insulation upgrades, protected piping routes, and backup power for critical systems now appear in scopes that previously omitted them, particularly in North and West Texas.
• Dust and airborne particulate: projects in Ector County, Midland County, Lubbock County, Potter County, and Randall County contend with filtration and maintenance considerations that Gulf Coast projects do not.
• Hail exposure: the North Texas hail corridor across Tarrant County, Dallas County, and surrounding areas makes hail guards on condensers a routine and worthwhile inclusion.
• Site access and laydown: an urban infill site in downtown Houston or Austin with no laydown area and restricted crane access carries labor and logistics costs that a greenfield site in Kaufman County or Hood County simply does not.

13. Commissioning, Testing, and Closeout

The final ten percent of an MEP scope contains more cost than most budgets acknowledge. Test and balance, controls point-to-point verification, functional performance testing, generator load bank testing, medical gas certification, fire alarm acceptance testing, and owner training are all real activities with real hours.

On projects pursuing certification — LEED, Austin Energy Green Building, or an owner’s internal standard — commissioning scope expands further, and enhanced commissioning adds design review and post-occupancy verification. Estimates that omit these activities are not cheaper projects. They are projects that will discover the cost during closeout, when leverage is at its lowest.

14. Contingency, Escalation, and Risk Allowances

Contingency is not padding. It is a priced acknowledgment that information is incomplete, and it should shrink as design advances rather than disappearing on the day construction starts.

• Design contingency: covers scope that will emerge as documents develop. Highest at concept, lowest at construction documents.
• Construction contingency: covers unforeseen conditions during the build, which matter most in renovation and adaptive reuse.
• Escalation allowance: covers the gap between today’s pricing and the projected construction midpoint.
• Procurement risk allowance: covers expediting, storage, or substitution driven by lead-time constraints.

Stating each of these separately, with its basis, is one of the clearest indicators of a well-built estimate. A single lump percentage tells a reader nothing about what risk was actually considered.

Ranking the Drivers: Where the Money Actually Moves

Every project is different, but across typical Texas commercial work the relative influence of these drivers tends to follow a recognizable pattern.

Cost Driver	Relative Impact	Best Point to Control It
HVAC system type and load	Very high	Schematic design, before equipment is scheduled
Electrical service and gear	Very high	Early load study and utility coordination
Labor rate and productivity	High	Constructability review and prefabrication planning
Equipment lead times	High	Early procurement packaging
Building type and program	High	Programming and feasibility
Design completeness	High	Before issuing any budget number
Code and local amendments	Moderate to high	Jurisdiction confirmation at project start
Underground plumbing scope	Moderate to high	Geotechnical and civil coordination
Material escalation	Moderate	Pricing date discipline and escalation line
Commissioning and closeout	Moderate	Scope definition during design
Permits and impact fees	Low to moderate	Jurisdiction research during due diligence

How MEP Cost Drivers Shift Across Texas Regions

A statewide average is a useful starting point and a poor finishing point. Here is how the same building program tends to behave in different parts of Texas.

Dallas-Fort Worth Metroplex

Dallas County, Tarrant County, Collin County, Denton County, Rockwall County, and Ellis County form one of the most active construction markets in the country. Deep subcontractor availability helps competitive pricing, but sustained demand keeps rates firm. Expansive clay soils influence underground plumbing, hail exposure influences equipment protection, and rapid suburban growth in Frisco, Prosper, McKinney, and Celina brings impact fees and utility extension costs into play.

Greater Houston and the Gulf Coast

Harris County, Fort Bend County, Montgomery County, Brazoria County, Galveston County, and Jefferson County share high humidity and a high water table. Latent cooling load raises mechanical scope, dewatering raises underground plumbing risk, and flood and wind requirements raise equipment placement and anchorage costs. Industrial and petrochemical demand along the Houston Ship Channel and in Beaumont and Port Arthur competes for the same skilled trades that commercial projects need.

Austin and Central Texas

Travis County, Williamson County, Hays County, Bastrop County, and Comal County combine strict local energy and green building expectations with rocky terrain and a fast-moving development pipeline. Rock excavation affects underground utilities, sustainability targets affect controls and commissioning, and sustained growth in Round Rock, Cedar Park, Georgetown, Kyle, and San Marcos affects both labor availability and jurisdictional fees.

San Antonio and South Central Texas

Bexar County, Guadalupe County, Comal County, and Medina County generally price somewhat below Austin while sharing similar climate demands. CPS Energy coordination, a strong healthcare and military construction sector, and steady multifamily volume shape the market. Institutional work here often carries higher ventilation and redundancy requirements than the regional average suggests.

South Texas and the Rio Grande Valley

Hidalgo County, Cameron County, Webb County, Nueces County, and Starr County face extended cooling seasons, coastal exposure near Corpus Christi and Brownsville, and a labor pool that tightens quickly when large industrial or port projects mobilize. Long cooling hours make efficiency decisions unusually consequential over a building’s life.

West Texas and the Permian Basin

Midland County, Ector County, Reeves County, Ward County, and surrounding areas are the clearest example of a market where labor, not material, sets the price. When drilling activity rises, skilled trades follow the energy sector, and commercial MEP pricing in these counties can exceed major metropolitan rates. Travel, lodging, and per diem belong in every estimate for this region.

El Paso, the Panhandle, and North West Texas

El Paso County sits in a drier climate zone where evaporative and hybrid cooling strategies are viable and dehumidification is far less demanding. Lubbock County, Potter County, Randall County, and Taylor County face wider seasonal swings, so heating scope carries more weight than it does on the Gulf Coast. Distance from major distribution centers adds freight and mobilization to both material and labor lines.

East Texas and the Brazos Valley

Smith County, Gregg County, Angelina County, Brazos County, and McLennan County offer generally lower labor rates than the largest metros, offset by thinner subcontractor coverage for specialized scopes. Institutional work tied to universities and regional medical centers in Tyler, Waco, College Station, and Temple in Bell County often requires capability that must be brought in from Dallas, Houston, or Austin, which shows up as mobilization cost.

Practical Ways to Control MEP Costs Early

The leverage in an MEP budget is front-loaded. Decisions made in the first fifteen percent of the design timeline determine the large majority of final cost.

• Run a real load calculation before pricing. Square-foot rules of thumb are fine for a napkin. They are not fine for a budget you intend to defend.
• Compare systems, not just brands. A side-by-side of VRF, packaged rooftop, and chilled water — first cost, energy cost, maintenance, and space impact — is the single highest-value analysis available in early design.
• Confirm the jurisdiction in writing. City, county, ETJ, MUD, and utility provider all affect scope. Confirm before assuming.
• Identify long-lead items at schematic design. You cannot mitigate a procurement risk you have not named.
• Value engineer during design, not after bidding. Post-bid value engineering means redesign fees, resubmittals, and lost schedule. Pre-bid alternatives cost nothing but attention.
• Estimate from a documented basis. Record pricing date, quantity source, productivity assumptions, wage basis, and every exclusion.
• Update the estimate at each design milestone. An estimate that is only produced once is a historical document by the time it is needed.

Common Mistakes That Inflate MEP Budgets

• Using a national benchmark without adjusting for Texas climate zone, wage rates, and local code amendments.
• Pricing equipment without accounting for the accessories, curbs, disconnects, seismic or wind restraints, and startup that come with it.
• Treating fire protection, low-voltage, and controls as small change when they routinely represent a meaningful share of the package.
• Ignoring demolition and temporary systems in renovation work.
• Carrying a single blended contingency percentage with no stated basis.
• Omitting escalation on a project that will not break ground for a year.
• Failing to reconcile the estimate against the mechanical and electrical schedules, which is where quantity errors surface fastest.
• Assuming a subcontractor bid is complete because it is low. Low bids are frequently incomplete bids.

Frequently Asked Questions About MEP Cost Drivers

What percentage of construction cost is MEP in Texas?

For most commercial buildings the MEP package falls between fifteen and forty percent of total construction cost. Warehouses and shell buildings sit at the low end, offices and schools in the middle, and healthcare, laboratory, and data center projects at the high end. The correct answer for your project depends on building type, system selection, and location far more than on any statewide average.

Which single component has the biggest impact on an MEP budget?

In a cooling-dominated climate like Texas, HVAC system selection is usually the largest single lever, with electrical service capacity a close second. On data-intensive or highly redundant facilities, electrical takes the top position outright.

When should an MEP estimate be prepared?

As early as programming, and then again at every design milestone. Early estimates carry wider ranges but influence far more of the final cost. Waiting until construction documents are complete gives you accuracy at exactly the point where you have the least ability to act on it.

Why do two MEP estimates for the same project differ so much?

Almost always because of scope assumptions rather than arithmetic. Different equipment tiers, different exclusions, different wage bases, different escalation treatment, and different contingency levels can easily produce a twenty percent spread. Comparing the assumption lists is more revealing than comparing the totals.

Does location within Texas really change the number that much?

Yes. The same building priced in Ector County, Harris County, and Travis County will produce three different numbers driven by labor availability, climate-driven equipment sizing, local code amendments, permitting and impact fees, and freight. Location is not a rounding factor in Texas — it is a primary input.
