From cross-office lunches and “Lunch & Learns” to volunteering in the neighborhoods where we live and work, we make time to connect, learn and give back.

structural evaluations for buildings of every type Wallace provides structural evaluations for a wide range of building types and materials, including concrete, masonry, steel, wood and cold-formed steel. Our team conducts condition surveys, forensic investigations and peer reviews and evaluates existing structures for additions, expansions and strengthening. We utilize non-destructive tools such as infrared surveys to identify masonry defects and moisture infiltration in roofing systems. We also assess existing buildings for compliance with current codes and load requirements, supporting projects from historic 19th-century structures to modern facilities.

comprehensive assessments and inspections We provide structural assessments, roof assessments and IBC-mandated special inspections that help maintain the integrity and performance of your buildings. Our engineers evaluate structural components to identify deficiencies and recommend practical repair or reinforcement strategies. For roofing systems, we assess condition and performanceidentifying leaks, damage, or aging - and provide guidance on repair or replacement. As part of the owner’s quality assurance process, our team provides special inspections to observe the installation of key structural and life-safety components. Working in accordance with the International Building Code (IBC), we help confirm that work in the field aligns with the approved design and relevant standards. Our inspectors - certified across steel, concrete, masonry, wood and fire-resistive materials- bring strong technical expertise, thorough documentation and responsive support on site.

here when you need us most When unexpected events occur, our team is ready to assist. Wallace has responded to buildings affected by earthquakes, tornadoes, hurricanes, storms, heavy snowfall, foundation issues and landslides. We understand the urgency of these situations and provide prompt evaluations to identify hazards, assess damage and recommend effective repair solutions that help protect occupants and preserve structural integrity.

civil engineering Shaping the ground we build on and the systems that make communities function.

we design the infrastructure that keeps communities moving Civil engineering at Wallace goes beyond infrastructure - it’s where vision meets reality. Our team supports cities, counties, state agencies and private developments with site development, water and wastewater systems, utility transmission and distribution, stormwater management, streets and highways and land development projects.

understanding your site before we begin Before designing improvements, we perform thorough site investigations to assess topography, vegetation, existing structures, infrastructure and local context. This due diligence informs thoughtful, practical designs, helping projects move forward efficiently, avoid surprises and balance performance, constructability and long-term value. pre-design Due Diligence Reports Feasibility Studies Land Use Entitlement & Permitting Utility & Infrastructure Assessment Site Master Planning Watershed Planning Hydrologic & Hydraulic Studies Transportation Planning Traffic Studies Surveying & Mapping

landscape architecture The land has a story to tell. We’re just here to help it speak.

we design with nature and people in mind Our landscape architecture team turns outdoor spaces into experiences - places that invite you in, keep you curious and make you want to stay awhile. Landscape architecture brings life to the spaces between. It shapes how people experience the outdoors – how they gather, move, pause and connect. From parks and plazas to campuses and streetscapes, we bring a holistic lens that balances beauty, ecology and the rhythms of daily life. We’re big on collaboration, light on ego and always thinking about how to balance beauty, function and sustainability. What sets our team apart is the way we listen and respond – to clients, to communities and to the land itself. We design with empathy, guided by a strong understanding of context and long-term stewardship. pre-design Site Analysis Site Selection Site Planning Campus Master Planning Park and Trails Planning Feasibility Studies Public Art

surveying

We speak the language of the land.

we lay the groundwork for informed decisions Surveying is the quiet constant behind progress—the first step in understanding a site and the foundation on which every decision is made. At Wallace, our land surveying team captures the data that grounds design decisions and starts every project on solid footing. We turn raw information into clarity, helping clients see the full picture before the first line is drawn or the first stake is set. Our services include topographic, boundary, alignment, ALTA/NSPS and as-built surveys, as well as subdivision platting, lot and parcel splits, easement creation and vacations and legal descriptions.

a clear understanding before design begins Before design moves forward, we precisely measure and map existing conditions to establish boundaries, elevations and key site features. This level of due diligence reduces risk, informs the design team, streamlines permitting and achieves accuracy during construction and final documentation. With Wallace, projects begin with confidence and move forward with fewer surprises. planning • design Topographic Surveys Boundary Surveys ALTA/NSPS Land Title Surveys Commercial Site Development Surveys Right-of-Way Surveys Pipeline Surveys construction Construction Staking As-Built Surveys Detention Pond As-Builts and Volume Determination
