STI Group is an experienced service provider of site improvement and preparation for civil construction projects. As part of our comprehensive civil engineering services, we are equipped to handle all preliminary aspects of construction site preparation, allowing for the efficient execution of subsequent phases of land development services. Our broad scope of knowledge, dedication to service and quality, and unwavering emphasis on safety ensure each project gets off to the right start with a solid foundation.
Clearing and Grubbing
Our land clearing and grubbing services involve the safe and effective removal of trees, shrubs, bushes, stumps, and other vegetation and debris from the construction site. This initial phase of earthwork and grading is critical for creating a worksite that is open, clear, and ready to be developed. STI Group’s experienced workers execute these tasks efficiently, setting the stage for further commercial site development.
Subgrade Stabilization
Subgrade stabilization is a vital part of foundation excavation. It involves stabilizing the underlying layers of soil to prevent shifting or caving in during construction. This is done by blending cement or lime with a stabilizing agent, considering factors such as moisture content, soil composition, and other environmental conditions. STI Group carefully analyzes these factors to provide effective, dependable subgrade stabilization and erosion control measures.
Heavy Haul Roads
Heavy haul roads are essential at construction sites for facilitating access by machinery, equipment, and personnel. These roads must be constructed to bear significant weight, adhering to a specific timeline and budget. As a skilled general contractor and provider of EPC services, STI Group builds safe and reliable heavy haul roads tailored to the unique needs of each project and worksite, ensuring effective construction site utilities installation.
Shoring
Shoring is a critical process that prevents worksite collapse, as well as corrosion and weathering. This service requires a thorough environmental site assessment, quality materials, and skilled crews. STI Group delivers safe and reliable shoring services, ensuring the site remains stable throughout the construction process.
Excavation
Site excavation involves the removal of soil, rock, and other materials to prepare the worksite for construction. This process, which is part of broader earthwork and grading services, requires heavy earthmoving equipment and trained work crews. With our extensive background as a full-service general contractor, STI Group is well-equipped to handle all aspects of excavation with the highest level of safety and quality.
Drainage Systems
An essential component of stormwater management and construction safety standards is the installation of drainage systems. These systems remove stormwater from the site or sewage from plumbing systems. STI Group’s services include excavating the necessary trenches and installing the piping, culverts, and other components needed for effective site drainage and erosion control.
Water Distribution Systems
Water distribution systems are crucial for delivering potable water to the construction site. STI Group ensures these systems are installed according to the highest civil construction standards, including those set by the American Concrete Institute (ACI) and the American Society for Testing and Materials (ASTM International).
Curbs, Sidewalks, and Parking Lots
Curbs, sidewalks, and parking lots are vital infrastructure for foot and vehicular traffic access. Their construction must account for both immediate and long-term needs. STI Group adheres rigorously to civil engineering standards to ensure these structures meet the highest levels of quality and durability, supporting safe and efficient access throughout the project lifecycle.
STI Group’s comprehensive EPC services encompass all phases of a construction project, from green field to a fully developed site. We transform marshes, forests, or undeveloped land into ready-to-build sites, providing the highest levels of service and quality during this crucial early phase of construction. Our commitment to safety, reliability, and excellence in construction project management sets the tone for the entire project, ensuring success from start to finish.
