SITEWORKS

What SITEWORKS does

SITEWORKS (SiteWorks LLC) is a privately held specialty landscape architecture and construction management practice founded in 2005 by Annette Wilkus and headquartered in New York City, with a second office in Olympia, Washington. The firm employs approximately 13 professionals — licensed landscape architects, ISA Certified Arborists, LEED-certified staff, ecologists, construction managers, and operations strategists — and operates with a partnership structure under current Partners Andrew Lavallee, Julia Gold, John Payne, and Ruth Nervig, with Annette Wilkus serving as Partner Emeritus.

The firm delivers integrated services across the full project lifecycle, anchored by two core offerings — Landscape Architecture (schematic design through construction documentation grounded in ecological restoration and urban landscape design) and Construction Management (constructability reviews, resident landscape architecture, and construction administration from design through closeout). These are supplemented by three specialized services: Arborist Services (tree value assessment and preservation planning), Operations & Maintenance Planning (maintenance guidebooks and lifecycle cost modeling), and Cost Estimating (itemized pricing integrated into the design phase). Differentiated technical capabilities include expertise in manufactured soils, slope stabilization, waterfront planting, and green infrastructure constructability.

Revenue is generated through professional-services fees billed to clients on a project-by-project basis. GTM is direct enterprise engagement with government agencies, public authorities, educational institutions, and developers — primarily secured through competitive procurement and direct negotiation. The firm holds WBE/DBE/SBE certifications across multiple jurisdictions and serves an iconic roster of clients including NYC EDC, NYC Parks, NYC DOT, Trust for Governors Island, National Park Service, Brooklyn Botanic Garden, Ford Foundation, Smith College, and the Port of Olympia. The firm has no outside investors, no parent company, and operates without a recurring revenue or subscription pricing layer.
