Civil Engineering & Site Development
Site planning, grading, drainage, utilities, and land-development coordination shaped around constructability.
Initiate project
One connected team for design, engineering, preconstruction, and construction—aligning every decision from site analysis through final delivery.
ALT connects technical analysis with field-tested construction experience. That integrated perspective produces clearer scope, stronger coordination, and fewer surprises.
Every service is designed to connect—with the site, the budget, the schedule, and the people responsible for delivery.
Site planning, grading, drainage, utilities, and land-development coordination shaped around constructability.
Disciplined field execution for commercial, residential, renovation, restoration, and exterior work.
Clear construction documents, architectural drafting, permit support, and 3D visualization.
Scope development, estimating, constructability review, and project coordination before work begins.
No blind handoffs. No disconnected decisions. Each phase carries the intelligence of the one before it.
Site, priorities, risk, and opportunity.
Drawings, scope, budget, and execution strategy.
Coordination, field leadership, and quality control.
Closeout, documentation, and final resolution.
A live view of ALT projects, details, and completed work—managed directly by our team.
Admin gallery accessALT Consultants & Contractors is built on the technical career of Luis Loayza, whose experience spans more than two decades across CAD management, surveying, civil and site design, construction estimating, field-data processing, and major infrastructure coordination in the United States and Peru.
That background connects office design with field reality. From Civil 3D corridors, grading, and earthwork models to GIS, drone data, point clouds, as-builts, submittals, and construction layouts, ALT approaches every project with a practical understanding of how information must move from survey to design to construction.
Experience supporting rail and station work, land development, construction operations, and mining infrastructure has shaped a company culture centered on technical clarity, responsive coordination, and buildable solutions.
