Grading Plans

A plan showing how the land will be graded and shaped for a project. It indicates the elevations, slopes, cuts, and fills necessary to ensure proper drainage and prepare the site for construction. It is essential to prevent flooding.

Utility Plans

It is a plan that shows the location and layout of underground and overhead utility installations, such as water, sewer, electricity, gas, and telecommunications. It helps coordinate the safe installation of these networks and avoids conflicts during construction.

Street Improvement Plans

This plan details proposed improvements to streets and roadways, such as paving, sidewalks, curbs, ramps, signage, and drainage. Its purpose is to improve safety, accessibility, and functionality for vehicular and pedestrian traffic, while meeting municipal standards.

Water Quality Management Plan

(WQMP) is a technical document that describes the strategies and measures to be implemented in a project to minimize stormwater pollution. Its objective is to protect water quality by controlling runoff, filtering pollutants, and complying with local and state environmental regulations.

Hydrology Reports

Diagram showing the merger of two lots, labeled Lot A and Lot B, with a combined property boundary around them, and indicating the proposed merger.

It is a technical study that analyzes how rainwater flows through a site. It includes calculations of runoff, flood zones, and drainage capacity. Its purpose is to ensure that the project design adequately manages stormwater, preventing flooding and meeting the authorities' hydraulic requirements.

Lot Merger

It is the legal and technical process by which two or more contiguous lots are combined into a single property. This procedure is used to facilitate larger developments, comply with zoning requirements, or simplify ownership. It requires approval from the local authority and is usually accompanied by plans and official documentation.

Corner Records

It is a technical document used to officially record, reestablish, or mark the location of corners or monuments of property lines, sections, or subdivisions. It is typically prepared by a licensed surveyor and filed with the county to ensure the accuracy and permanence of the legal boundaries of the land.

Construction Staking

It is the process of marking the exact locations of construction elements, such as foundations, curbs, pipes, or structures, on the site based on project plans. These marks guide contractors throughout the project to ensure everything is built accurately and according to the approved design.

Slope Analysis

It is a study that evaluates land slopes to identify areas at risk of landslides, erosion, or drainage problems. It is essential in construction and urban development projects, as it helps determine soil stability, the appropriate design of slopes, and the viability of development based on the natural topography.

Architectural Services

Height Certification

A certified surveyor's certificate is a document issued by a licensed surveyor that verifies the height of a constructed structure relative to a specific reference point, such as sea level or natural terrain. This certificate ensures that the building complies with the height limits established by local zoning or aviation regulations.

A topographic survey map showing contour lines, elevation numbers, and marked areas, with a green square indicating a specific zone, and the text 'Topographic Survey Map' at the bottom.

Topographic Survey Map

It is a detailed plan that shows the physical and natural features of a site, including elevations, slopes, trees, buildings, bodies of water, and other visible structures. This type of survey is essential for the design and planning of construction projects, as it provides an accurate representation of the site's surface.
