Rough-In Works for MEP: Wall Chases, Embedded Parts, and Service Penetrations (Anaheim)

Before drywall goes up and finishes begin, a project needs accurate rough-in preparation for engineering systems (MEP: electrical, plumbing, HVAC, low-voltage). This stage includes wall chases (often called “shtroby”), embedded parts (zakladnye), and service penetrations (prokhodki). Done correctly, these works keep routes clean, reduce rework, and help inspections pass on the first attempt—especially important during construction and renovation in Anaheim. Wall chases are controlled grooves in masonry, plaster, or concrete for cables, pipes, and conduits. The key is planning: mark routes from the approved layout, avoid load-bearing conflicts, keep safe distances from corners and openings, and maintain clear separation between power and low-voltage lines. Using the right tools (wall chaser with dust extraction, diamond cutting where required) improves precision and keeps the site safer. Embedded parts are pre-installed elements that will later receive equipment and fasteners: brackets for HVAC units, mounting plates for cabinets, anchors for handrails, supports for manifolds, and backing for heavy fixtures. Installing them early ensures correct height, alignment, and load capacity, preventing cracked finishes and weak fixings. Service penetrations include holes and sleeves through walls, floors, or ceilings for pipes, ducts, and cable trays. Proper sizing, edge protection, and fire- or moisture-sealing (where needed) are essential. Documenting locations, taking photos before closing walls, and coordinating with other trades helps avoid surprises. A well-managed rough-in phase saves time and budget, keeps the project tidy, and sets a reliable foundation for the final installation and finishing work.
