How it works


01 / 04

Project Initialization

Before diving into a project, our drafting managers arrange a call to discuss your specific land surveying requirements. This includes understanding the type of survey needed, location details, requirements from the Title company, and preferred data acquisition methods. We consider all the specifics such as Site Location, prior surveys, county maps, legal descriptions, CAD templates, land use, utilities, OHE, and underground utilities. Armed with this comprehensive information, we collaboratively outline a strategic plan for the project.

02 / 04

Role of Operations Department

Our proactive Operations department develops a tailored plan based on the estimated volume of work you'll provide during a specific period - be it a week, month, or quarter. Once we have a grasp of your volume, our Ops team allocates team leaders, quality checkers, and drafters accordingly. Our Quality department collaborates closely with your managers to agree on initial quality metrics and then establishes a quality-check template that remains in effect until new updates are incorporated. Rest assured, all our jobs undergo rigorous QC verification based on the approved quality templates.

03 / 04

Technology Engagement

Our Technology department works hand-in-hand with the Operations department to address any technical challenges that may arise in specific projects. This is particularly relevant for lidar or photogrammetry projects that occasionally encounter issues like point cloud projection, classification and splicing of massive point clouds, or software compatibility. Our tech team ensures that no such issues hinder your project's progress or lead to unnecessary delays.

04 / 04

Final Deliverables

We pride ourselves on delivering top-quality final products in CAD and PDF formats. Prior to seeking client reviews, we conduct thorough quality checks on our deliverables. Upon receiving feedback, we carry out any necessary revisions to ensure that the final output aligns perfectly with your expectations. Delivering nothing but the best is our commitment to you.
