Civil Engineering Services

Civil engineering supports the planning and design of sites, roads, utilities, drainage systems, and related infrastructure. Sitts & Hill provides civil engineering services directly to public and private clients and as a subconsultant on architect-led design teams.

Its published capabilities include site and parking layouts, utility design, roadway design, stormwater management, sewer systems, fire and domestic water systems, pedestrian routes, and circulation improvements.

Civil engineering also involves evaluating site conditions, understanding jurisdictional requirements, preparing technical calculations, and coordinating permitting. Depending on the project, the team may provide feasibility studies, cost estimates, specifications, reports, and construction support.

These services are relevant to new developments, facility expansions, infrastructure improvements, and redevelopment projects. By coordinating civil design with structural engineering, surveying, and architectural services, Sitts & Hill helps clients address technical requirements across different project stages.

Structural Engineering and Building Design

Structural engineering focuses on the analysis and design of systems that support buildings, equipment, and other structures. Sitts & Hill provides structural engineering services for new construction, facility upgrades, redevelopment, and industrial applications.

Its published services include structural calculations, building and site layout, foundation design, gravity and lateral analysis, structural evaluations, and technical reports. The company also provides design and analysis for specialized tools and equipment.

Structural requirements can vary considerably depending on building configuration, materials, expected loads, environmental conditions, and applicable codes. Industrial projects may require additional consideration of equipment loads, operational requirements, access, and existing facility constraints.

Sitts & Hill coordinates structural engineering with other project disciplines to support practical designs and clear construction documentation. Clients can discuss their building type, proposed modifications, and project objectives with the firm to determine the appropriate engineering scope.

Industrial Engineering and Facility Design

Sitts & Hill has experience with light and heavy industrial projects, including facilities in aerospace, oil and gas, rail, marine, and manufacturing-related environments.

Industrial facilities often require coordinated engineering for equipment foundations, plant layouts, structural systems, access platforms, utility infrastructure, and operational improvements. Projects may also involve modifications to existing facilities where engineers must consider established equipment arrangements, site constraints, and ongoing operations.

The firm provides general arrangement and plant layout services, code compliance studies, specialized foundations for machines and equipment, underground vaults, flight-line infrastructure, duct banks, and BIM and 3D modeling support.

Its industrial engineering team can work as a prime consultant, lead design professional, construction contract administrator, or owner’s representative, depending on the project requirements.

This range of capabilities is relevant to industrial owners and contractors seeking engineering support for facility expansions, equipment installations, infrastructure improvements, and specialized structural projects.

Architectural Design Services

Sitts & Hill offers architectural services that complement its civil and structural engineering capabilities. Its published architectural services include building design, code analysis, cost analysis, project scheduling, specifications, BIM modeling and rendering, MEP coordination, permitting coordination, bid coordination, and construction support.

Architectural design requires coordination between the intended use of a building, its layout, technical systems, construction methods, and applicable building requirements. Integrating architecture with engineering can help project teams address design interfaces and resolve practical issues before construction progresses.

The firm’s industrial and commercial experience allows it to support projects with specialized functional requirements. Clients should confirm the specific architectural services available for their building type and project location directly with the company.

Land Surveying and Mapping

Accurate surveying provides important information for planning, design, construction, and property documentation. Sitts & Hill offers land surveying services for public and private projects.

Its published capabilities include ALTA/NSPS land title surveys, boundary surveys, boundary line adjustments, topographic mapping, laser scanning and reality capture, UAV mapping, plats, condominium surveys, construction staking, GIS integration, as-built surveys, utility research and mapping, and legal description preparation.

Surveying helps project teams understand property boundaries, site elevations, existing improvements, utilities, and other physical conditions. These details can influence building placement, site design, infrastructure planning, and construction activities.

For projects involving existing facilities or complex sites, laser scanning and reality capture can help document existing conditions and support coordination with design models.

The appropriate survey scope depends on the property, intended use of the survey, jurisdictional requirements, and the project team’s needs.

Site Development and Permitting

Site development involves coordinating land use, site layout, infrastructure, drainage, access, and regulatory requirements. Sitts & Hill provides consulting engineering and surveying services for commercial, industrial, and residential site development.

Its services include platting, planning, site design, and permitting assistance. The firm works with owners and design teams to evaluate site features, analyze development constraints, and coordinate required approvals.

Projects may require coordination with local authorities and other agencies regarding drainage, utilities, transportation access, environmental requirements, or land use. Early identification of these considerations can help project teams establish a realistic design and approval process.

Sitts & Hill’s combination of civil engineering, surveying, architectural design, and permitting support allows clients to coordinate multiple site-related requirements through a multidisciplinary team.

Supporting Services and Construction Coordination

In addition to its core engineering and design services, Sitts & Hill offers supporting services such as construction support, construction management, specification preparation, cost estimating, project administration, design quality control, and LEED-related design services.

These services help project teams coordinate technical documentation, manage design requirements, and address questions that arise as a project advances. The specific role of the firm depends on the contract, project complexity, and responsibilities assigned by the client.

The firm can serve in different consulting roles, including prime consultant and subconsultant. This flexibility allows its services to be integrated into larger project teams or used to address specific engineering and surveying requirements.
