What Sherwood Construction Co., Inc. does

Sherwood Construction Co., Inc. is a privately held, family-owned heavy civil construction firm founded in 1934 and headquartered in Tulsa, Oklahoma. Operating through a family of nine subsidiary companies, Sherwood self-performs urban expressways, bridges, concrete and asphalt paving, mass earthwork, site development, drainage, and underground utilities for state departments of transportation, turnpike authorities, cities, counties, and private industrial clients across the Midwest (Oklahoma, Kansas, Colorado, and Nebraska). Revenue is generated project-by-project through competitive bidding on public infrastructure contracts (with single-project values ranging from $35M to $87M) and direct negotiation with private industrial, manufacturing, oil and gas, and food processing clients, with no publicly disclosed pricing or revenue figures.

The company's competitive structure is built on vertical integration: wholly owned materials subsidiaries produce asphalt (Millennial Asphalt), crushed limestone (Greenhill Materials), ready-mix concrete (Greenhill Concrete), spec sand and aggregates (Greenhill Sand, acquired 2021), and rail-transloaded aggregates (Oklahoma Construction Materials), all feeding both internal projects and external contractor sales. Specialty subsidiaries Klaver Construction (concrete box culverts and bridges) and Borton, LC (slip form concrete, millwright, specialty structures) extend the capability set. Sherwood's technology platform includes a fleet of 46 GPS-enabled dozers, motor graders, excavators, and 3D milling/paving sub-grade trimmers, in-house CAD and 3D modeling, two survey managers and four survey crews using Trimble equipment, plus UAV drone and robotic scanner technology for existing-condition capture.

The business is supported by a leadership team including CEO David Sherwood and President Kyle Conaway (promoted from intern), and a workforce of over 900 core employees. Distribution is exclusively direct enterprise: competitive public-sector bidding and private-sector negotiation. The go-to-market relies on long-standing owner relationships (ODOT, Oklahoma Turnpike Authority, City of Tulsa), a self-perform model that controls schedule and quality, and decades-long regional brand equity dating to the founding Sherwood brothers' first truck crane during the Great Depression. The company has remained family-owned with no disclosed external private equity investment.

Direct peers

• Duit Construction: Edmond, OK-based heavy civil contractor performing earthwork, utilities, paving, and structures across Oklahoma and surrounding states. Similar self-perform model and competing head-to-head for ODOT and municipal contracts in Sherwood's primary geography.
• Crossland Construction Company: Tulsa, OK-based general contractor and heavy civil builder. Already partnered with Sherwood on The Gathering Place project, operating in the same geography with overlapping self-perform earthwork, paving, and structure capabilities — directly comparable customer base and project profile.
• Sterling Construction Company: Texas-based publicly traded heavy civil construction company focused on transportation, water, and specialty services across the Sun Belt. Operates in many of the same state DOT markets as Sherwood, with similar earthwork, paving, and bridge capabilities at slightly larger scale.
• TTK Enterprises: Oklahoma-based heavy highway and bridge contractor serving ODOT, OTA, and municipal clients. Comparable self-perform capability on interchange, paving, and earthwork projects in the same Midwest market as Sherwood.
• Manhattan Road & Bridge: Oklahoma-headquartered heavy highway and bridge contractor serving ODOT and Oklahoma Turnpike Authority. Directly competes for the same public interchange, bridge, and roadway projects in the same regional market as Sherwood Construction and Wildcat Construction.

Broad incumbents

• Granite Construction: Large national heavy civil contractor with vertically integrated materials (aggregates, asphalt) operations — directly analogous to Sherwood's vertically integrated model but at national scale. Competes for state DOT projects and operates own quarries/asphalt plants like Sherwood's subsidiaries.
• Martin Marietta Materials: One of the largest U.S. producers of aggregates and heavy building materials. Comparable to Sherwood's vertically integrated materials business (Greenhill Materials, Oklahoma Construction Materials) but at national scale — illustrates both the strategic logic of vertical integration and the scale Sherwood would need to compete on materials beyond its region.
• Balfour Beatty US Civil Construction: Major civil contractor operating across the U.S. on highway, bridge, rail, and water infrastructure projects. Competes with Sherwood for state DOT and turnpike authority work in multiple states, but at significantly larger scale and with broader geographic reach.

Regional players

• Dolese Bros. Co. Oklahoma's largest producer of ready-mix concrete and aggregates — directly comparable to Sherwood's Greenhill Concrete and Greenhill Materials subsidiaries in the same geography. As a regional materials peer, Dolese competes for the same external aggregates/concrete sales that complement Sherwood's vertically integrated materials business.
• APAC-Central Inc. Oklahoma and Arkansas-based asphalt and aggregate producer serving state DOT and private paving customers. Directly comparable to Sherwood's Millennial Asphalt and Greenhill Materials operations in the same regional market.
