Introduction
Construction cost escalation has become a critical concern in the U.S. commercial real estate sector. Over the past few years, construction costs have risen at rates far exceeding general inflation, driven by surges in material prices, labor shortages, and supply chain disruptions. Investors and developers are grappling with disparities between official inflation indices (such as Consumer Price Index or producer price indices for materials/labor) and the real-time bid prices coming in from contractors. This report examines how construction material and labor cost indices compare to actual bid price inflation across major asset types. We pay special attention to RV park development – a growing asset class in outdoor hospitality – to illustrate how cost volatility is affecting site planning, design, infrastructure, and project financing. We also discuss why a “construction cost escalation dashboard” that tracks material & labor trends vs. bid prices by asset type would be a valuable tool for stakeholders.

Indices vs. Reality: Material & Labor Costs vs. Bid Price Inflation
It’s important to distinguish between official inflation indices and the actual prices builders charge. The Consumer Price Index (CPI), which tracks a broad basket of consumer goods, “is not related at all to construction and should not be used to adjust construction pricing”. Likewise, generic input cost indices (for example, producer price indices for raw materials) do not capture the full scope of what a developer will pay to build a project. In contrast, contractor bid prices (sometimes called final demand or selling price indices) include all costs plus contractor overhead and profit. As one construction economist explains, general input indices “don’t track whole building final cost and do not capture the full cost of escalation in construction projects,” whereas selling price indices reflect the total actual cost including labor, materials, and margins. In periods of high demand, contractors often widen their margins, causing final bid prices to rise faster than inputs alone.
To illustrate the gap, consider the recent extreme inflation cycle. In 2021, many construction material prices exploded – the producer price index (PPI) for nonresidential construction inputs at one point rose 24% year-over-year (June 2021) and stayed above 20% annualized through early 2022. Meanwhile, wages for construction labor rose more moderately (on the order of 5–6% annually), and general consumer inflation (CPI-U) was about 7% in 2021. However, contractors could not immediately pass all these increases to owners – competition and fixed-price contracts initially kept bid prices lower. In 2021, contractor bid price indices (final demand construction) increased by roughly 12% on average, roughly half the rate of material cost spikes. This created a huge gap between input costs and what builders charged.
By 2022, that situation reversed – builders “caught up” with earlier input inflation by raising bids sharply. Material cost indices began to moderate (some commodity prices even fell), but bid prices jumped. The PPI for construction final demand surged 18.5% year-over-year in 2022, even as input price growth cooled to around 7–8%. In fact, by late 2022 contractor bid prices were still ~18% higher year-on-year while material input costs were up only ~2% – a sign that bids were incorporating past run-ups and risk premiums. The chart below illustrates this convergence: after lagging behind in 2021, bid price inflation (blue line) nearly caught up to cumulative material cost inflation (red line) by the end of 2022.
Construction input cost vs. bid price inflation (US % change year-over-year). By Dec 2022, contractor bid prices had risen ~18% y/y (blue) while material cost indices were up only ~2% y/y (red), reflecting contractors catching up on margins. Early 2021 saw the reverse – materials spiked ahead of bid prices, creating a gap.
Table 1 – Construction Cost Inflation vs. Consumer Inflation (2021–2022) (Annual percentage increase)
Index (Inflation Measure) | 2021 | 2022 |
Consumer Price Index (CPI-U) – general inflation | 7.0% | 6.5% |
Construction Materials PPI – inputs to construction (goods) | +22.8% | +7.7% |
Construction Labor Costs – avg. wages/compensation | ~5% | ~5% |
Contractor Bid Price Index – final building cost (PPI Final Demand) | +12.2% | +18.5% |

As Table 1 highlights, construction cost inflation far outpaced general CPI in 2021–2022. Over that two-year span, material costs jumped cumulatively ~30% (with certain inputs far higher), while bid prices rose roughly 33% in total. Historically, this is not unusual – “long-term construction cost inflation is normally about double the consumer price index”, due to the sector’s unique supply/demand dynamics. Furthermore, the difference between input costs and final costs often comes down to contractor margins and market conditions. When construction activity is booming and backlogs are full, contractors can charge premium prices – in other words, “when construction volume increases rapidly, margins increase rapidly,” adding to inflation on bids. Conversely, in downturns contractors may absorb more costs to win work, narrowing the gap. This cyclical behavior means real-time bid prices can diverge significantly from government indices that track only materials or labor in isolation.
Construction Cost Trends by Asset Type
Not all commercial asset types experience cost escalation equally – the composition of materials, labor, and demand varies by sector. A bid price index “dashboard” by asset type would show that certain categories saw especially dramatic inflation recently. Below, we compare trends in a few key asset classes (focusing on non-residential construction):
Table 2 – Contractor Bid Price Inflation by Asset Type (PPI Building Cost Indices)
Asset Type (New Construction) | 2021 Bid Price ↑ | 2022 Bid Price ↑ |
Warehouse / Industrial | +20.4% | +20.9% |
Office Buildings | +13.0% | +20.2% |
Manufacturing/Industrial (other) | +13.4% | +20.5% |
Healthcare Facilities | +11.4% | +18.0% |
School / Institutional | +9.0% | +17.9% |
Nonresidential Building Avg | +12.4% | +19.4% |

Several insights emerge from Table 2. Warehouse and industrial projects led cost escalation, with bid prices jumping ~20% each year in 2021 and 2022. This reflects the enormous demand for logistics facilities (and large quantities of steel, concrete, and electrical systems those structures require) during the e-commerce and manufacturing boom. Offices, while a softer market in demand, still saw construction bids up ~20% in 2022 as input costs and labor shortages hit all building types. Institutional projects like schools and healthcare facilities had slightly lower (but still very high) inflation in 2021, then spiked close to 18% in 2022. Across the board, 2022 was the peak for construction cost inflation in most sectors, as contractors priced in both ongoing supply-chain challenges and their stretched capacity.
Materials cost volatility played a role in these asset-specific trends. For example, warehouses rely heavily on steel structures and roofing – steel mill product prices soared 128% in 2021, then fell ~30% in 2022, whipsawing industrial project budgets. Office and commercial buildings use a broad mix of materials; they were hit by lumber and plywood spiking 37% in 2020, 18% in 2021, then crashing -19% in 2022, as well as continued increases in concrete, glass, and copper. Ready-mix concrete rose about 13% in 2022 amid cement shortages, affecting virtually all vertical construction. Meanwhile, labor shortages in skilled trades (plumbers, electricians, etc.) meant higher subcontractor bids in tight markets – e.g. electrical subcontractor costs jumped ~12% in 2022. The interplay of these factors differed by project type.
One noteworthy dynamic was how contractor behavior influenced different sectors. During this period, builders on high-demand projects (like big-box warehouses or data centers) had more leverage to charge premium rates, pushing those indices up faster. The U.S. Bureau of Labor Statistics data confirms that “commercial structures” saw 21% inflation in 2020 followed by stabilization, whereas some residential indices hit record highs then cooled. In fact, residential construction (e.g. single-family home building) had its own boom: homebuilding costs jumped ~15%+ in 2021–2022 by some measures, fueled by lumber volatility and a rush of demand. By late 2022 and 2023, construction inflation began to moderate in many categories as supply chains improved and rising interest rates dampened new project starts. Some indices even turned slightly negative quarter-over-quarter in 2023. However, the price level of construction remains extremely elevated – roughly 30% higher than pre-pandemic on average by 2023. This presents ongoing challenges for new development economics.
RV Park Development: Cost Volatility in a Growing Asset Class
RV parks (and campgrounds) have emerged as a growing asset class in the commercial real estate and outdoor hospitality sector. Investor interest in RV park development has surged thanks to rising domestic tourism, the popularity of RV travel among younger demographics, and attractive yields compared to traditional property types. However, RV park projects are not immune to construction cost volatility – in fact, they face unique challenges due to their heavy reliance on land development and infrastructure.
An RV park typically involves substantial site work (land clearing, grading, road and pad construction) and utility infrastructure installation (water, sewer/septic, electrical hookups, etc.), in addition to any buildings (office, restrooms, clubhouses) and recreational amenities. This means materials like asphalt, concrete, lumber, plastics, and metals form a large portion of costs – many of which experienced sharp inflation recently:
Petroleum-based materials: Asphalt for internal roads and RV pads became much more expensive when oil prices spiked. Paving asphalt prices jumped 16.2% in 2022 alone, on top of an 8% rise in 2021. PVC pipes and plastic components (used in water/sewer lines) saw a 35% price surge in 2021 and remained 8–9% higher in 2022. These increases directly inflate the cost to install utility networks and hardscaping in RV parks.
Concrete and aggregates: Campground construction often uses concrete for pad sites, foundations, and facility buildings. Ready-mixed concrete prices rose ~13% in 2022 nationally, while precast concrete products (e.g. utility vaults, septic tanks) were up ~13% as well. Even basic gravel and sand costs saw escalation due to fuel and demand. This drove up site preparation and pad construction budgets.
Lumber and building materials: If an RV park includes cabins, wood decks, or stick-built structures, the wild swings in lumber costs had an impact. Lumber spiked dramatically in 2020–2021 and then fell, causing budgeting whiplash. Gypsum drywall and insulation – used in bathhouses or community buildings – jumped ~17% and 15% respectively in 2022, raising the cost of vertical construction on-site.
Electrical gear and equipment: Perhaps one of the biggest challenges has been procuring key electrical infrastructure. The post-pandemic period saw a shortage of distribution transformers and related gear needed to connect new developments to the power grid. Transformer costs climbed 60–80% since 2020, with lead times stretching from ~50 weeks to nearly 2 years. For an RV park developer, this means higher bids for electrical installation and potential delays in getting sufficient power for all RV hookups. Generators, panels, and other equipment have also faced long lead times, forcing some projects to incur rush costs or temporary solutions.
For RV park developers, these cost escalations have real impacts on site planning and design decisions. For instance, when asphalt prices skyrocket, some choose to reduce paved roadways or use gravel for secondary paths to cut costs. High utility costs might lead to phasing of sites – perhaps initially developing fewer RV pads until material prices stabilize, or opting for dry campsites (no full hookups) in some sections. Layout and density considerations can change too: wider spacing and extra amenities (like large concrete patios or elaborate landscaping) may be scaled back when inflation squeezes the budget. Architects and planners are engaging in “value engineering” – optimizing designs to maintain functionality while substituting cheaper materials or more efficient methods. This might include using modular or prefabricated buildings for bathhouses or cabins to save on labor and material waste. Off-site modular construction can reduce costs by 20–30% and cut construction time 30–50% in some cases, a compelling option when on-site labor is expensive and time is money.
The financial risks and forecasting difficulties caused by input inflation are especially pronounced in RV park projects. Many RV park developments are undertaken by small operators or first-time developers who rely on loans and tight pro formas. When construction costs jump unpredictably (e.g. a bid coming in 20% over the initial budget due to price hikes), it can derail financing. Lenders now often require larger contingencies (10–20% or more) and detailed cost breakdowns before committing funds, to ensure the borrower can absorb overruns. If costs escalate mid-project, developers may need to inject additional equity or cut project scope. For example, a plan to include a swimming pool or solar lighting might be postponed if bids come back too high. Inflation adds uncertainty to appraisals and valuations as well – the “as-completed” value of the RV park must justify the increased construction cost, which can be challenging if cap rates are also rising. Indeed, industry observers note that rising interest rates and inflation have cooled some RV park deals, and park property prices have dipped 10–30% in the past year in response. While demand for RV sites remains strong, the cost to build new parks has become a moving target, making feasibility analysis more complex.
It’s not all bad news: there are signs of stabilization. Some input costs for RV parks have leveled off or even decreased from their peaks. Additionally, a slowdown in other construction sectors can free up contractor capacity and ease price pressure. For instance, “a slowdown in new housing developments reduces start-up costs for new parks, attracting investors” – essentially, when homebuilders retreat, contractors may bid more aggressively on RV park projects, yielding better prices for site work. Moreover, experienced campground developers are learning to adapt by locking in prices early for critical materials, sourcing locally to avoid high freight costs, and staggering development phases to manage cash flow. The volatility of recent years has underscored the need for robust contingency planning in RV park development. Smart developers now perform scenario analyses (e.g. “what if material costs rise another 10%?”) as part of their feasibility studies. They also negotiate escalation clauses in contractor agreements or purchase key materials in advance when feasible, to hedge against further inflation.
The Case for a Construction Cost Escalation Dashboard
Given the complex landscape of construction inflation, a dashboard that tracks material & labor CPIs versus bid prices by asset type would be an invaluable tool for the industry. Such a dashboard could aggregate data from sources like the Bureau of Labor Statistics, industry cost indexes (e.g. Turner, RLB, AGC), and real-time market surveys of contractor bids. By presenting side-by-side trends for inputs and final costs across different sectors, stakeholders can quickly identify disparities and turning points. For example, if steel and lumber costs are falling but contractors are still quoting high prices for industrial projects, an investor or developer might decide to postpone a warehouse build-out in hopes that bid prices will soon adjust downward. Conversely, if input prices start surging (say, a spike in copper or fuel costs) one could anticipate upward pressure on future bids and adjust budgets proactively.
A well-designed Construction Cost Escalation Dashboard would likely include:
Material Cost Indices by Category – e.g. lumber, steel, cement, asphalt, copper, plastics, gypsum – showing monthly or quarterly CPI/PPI changes. This helps contractors and developers monitor which inputs are driving cost changes (for instance, seeing concrete prices climbing could signal trouble for an RV park’s site work budget).
Labor Cost Trends – such as construction employment cost index or union wage rates, and even labor availability metrics. This informs staffing decisions and contract negotiations, as labor shortages can lead to bid premiums.
Bid Price Indices by Asset Type – drawing on data like the PPI Final Demand by industry (office, warehouse, etc.) or private cost indexes. Users could filter to see “commercial construction CPI trends” versus actual bid inflation for each asset class. This reveals, for example, that “industrial bid prices are 5% above their expected level given input costs” – a red flag that contractors are still charging a scarcity premium in that sector.
Geographic and Sector Breakdowns – since construction costs can be local, the dashboard might show regional indices or specific asset sub-types. For RV parks, perhaps a subset under hospitality or specialty real estate could be tracked if data is available (e.g. indices for infrastructure construction could be a proxy).
Forecast and Risk Indicators – using historical correlations, the dashboard might provide an outlook (e.g. if commodity prices are trending down, bid inflation might ease in coming quarters). It could also flag risks like “materials volatility index” or supply chain strain indexes that alert users to potential shocks (such as the transformer shortage).
The value of such a tool is significant for all parties: Contractors could use it to justify their bids to owners (backing up why a cost needs to be higher, or conversely seeing when to become more competitive if input costs ease). Developers and investors would gain a clearer picture of current cost realities, enabling more accurate pro formas and timing of projects – they could decide to accelerate a project if the dashboard shows a rising trend, or delay if a cost bubble is forming. Lenders and appraisers would also benefit; a dashboard provides transparent data to support construction loan decisions and contingency reserves. In short, real-time tracking turns the uncertainty of inflation into actionable intelligence.
From an SEO and information standpoint, combining terms like “material vs bid price index” in one place helps industry players find the data they need. For example, a user searching for “construction cost escalation 2025” could see the dashboard indicating that while general inflation is down, concrete and electrical equipment costs are still trending up, which may keep construction cost escalation positive but moderate for the year. In the RV sector, a search for “RV park development costs” might direct them to insights on how inflation in park infrastructure (like utility connections) is affecting project feasibility.
Conclusion
In today’s construction environment, knowledge is power – and nowhere is this more evident than in understanding construction cost escalation. The past few years have taught investors and developers a hard lesson: traditional CPI figures don’t tell the story of what’s happening on job sites. A combination of supply shocks, labor dynamics, and aggressive demand led to construction prices surging far above general inflation, with notable disparities between material/labor costs and final bid prices. We explored how different commercial asset types have been impacted, noting especially the high inflation in industrial projects and the challenges in RV park development – a niche that exemplifies how volatile input costs (from asphalt to transformers) can disrupt project planning.
Looking ahead, having a finger on the pulse of both consumer indices and contractor pricing is essential. Developers embarking on new projects – whether it’s a distribution center or a family-owned RV campground – must incorporate up-to-date cost data and remain flexible in design and procurement. Lenders and investors will continue to scrutinize construction budgets with an eye on inflation risk, making tools like a cost escalation dashboard and thorough contingency planning standard practice. On the upside, as inflationary pressures stabilize, opportunities will arise to execute projects more cost-efficiently, especially for those who tracked the trends and timed their decisions well.
In summary, construction cost escalation is now a key factor in commercial real estate strategy. By comparing material & labor indices vs. bid price trends by asset type, stakeholders gain clarity on where the market stands and where it’s headed. Whether you’re optimizing an RV park layout to hedge against rising costs, or adjusting a capital plan for an office development, staying informed through data-driven dashboards and reports will be crucial. Armed with this knowledge, contractors, developers, investors, and lenders alike can better navigate the new inflation-driven realities of building in America and make savvy decisions that balance cost, design, and value.
