Subdivision Staking encompasses utility staking, curb and gutter staking, property corner stakeout, overlot, including pond & swale grade staking, and any other staking to provide layout of a set of subdivision construction plans to physical points on the ground.
Utility Staking is usually a part of subdivision staking and is the staking of water lines, sanitary sewer lines, storm sewer lines, and any gas lines, electric lines, etc. that are a part of a subdivision or transmission line.
Building Layout is the layout of commercial buildings and large multifamily buildings.
Following safety standards, a crew will layout grid lines, caissons, building foundation, elevators, mechanical rooms, and internal walls as needed.
After a building is built on site, municipalities require that a Building Setback Certification be completed to prove that the building is in the correct location in accordance to setbacks, building envelopes, and property lines. Property lines are established, measurement of the building is done, and dimensions to the property lines from the building foundation are shown.
After a site is constructed, a Site Drainage Certification needs to be completed and the results sent to the engineer of record or the local government in which the site resides.
All curb and gutter, drainage pans, storm sewer, swales, and pond information is gathered as well as building finished floor elevations and ground shots to establish the drainage patterns of the constructed site with all improvements.
Road Layout consists of staking the horizontal and vertical location for both new construction and rehabilitation of roads. This includes slope staking, blue-tops for both sub-grade and top of base, as well as edge of asphalt staking.
Bridge Layout consists of laying out all structures required in bridge construction including, but not limited to, abutments and piers, wing walls, parapet walls, and one-tenth points on girders for cast-in-place concrete decking.
As time goes on, dam structures need rehabilitation and modernization to ensure the proper protection against failure and flooding. We work closely with hydrology and structural engineers to help determine the safety of these dams. We also work closely with engineers and contractors during construction of new dams to ensure the dam is built as specified in the approved set of plans.
All of the utilities and drainage is located horizontally and vertically after construction and put together in an As-built Survey. This survey is completed and sent to the engineer of record or the client so that it can be compared to the approved plans for the project.
Volume Calculations and Quantity Surveys are needed by many construction companies as a way of showing volume of dirt moved for construction purposes.
This includes stockpile surveys to calculate the volume of stockpiles for bidding purposes and billing purposes.
It also includes a pre-construction survey and a post-construction survey to calculate volume of dirt moved during construction for billing purposes.
