Our Land Surveying department is equipped with Differential GPS and Robotic Total Station technology. Our staff is trained in the use of all equipment and able to effectively transition between instruments as field conditions dictate.
While in the field, our survey crews are equipped with the hardware and software that enables them to become a mobile extension of our office. Laptop workstations are used in the field with the same software that is available to our office personnel. Project data can be processed immediately in the field or transmitted to the office. A tailored ATV allows the surveyor to get to places an ordinary vehicle cannot go.
Cornerstone Engineering Inc. has performed thousands of design surveys in support of our in-house design staff as well as the support of other engineering firm’s projects. Services include: setting aerial targets, establishing horizontal and vertical ground control, coordination of aerial mapping, and additional engineering design surveys to pick-up supplemental features. These may include underground pipelines and other utilities, additional elevations and contours, boundary lines, etc.
At Cornerstone Engineering as-built surveys are performed utilizing one of two basic methods. In the first method, the design information is loaded into the stake-out software of the total station, and differences between the plans and the actual locations noted in the field. The other method consists of performing the field locations and then comparing the field information in the office and updating plans as necessary. Often a combination of these two approaches is used. Pad certifications are completed in the same manner.
ALTA/ACSM Land Title Surveys
The American Land Title Association (ALTA) and the American Congress on Mapping and Surveying (ACSM) have developed special survey requirements to be followed in order to insure land titles without exception for matters that may be discoverable from a survey. These surveys are usually performed on commercial properties that are involved in real estate transactions. These surveys establish property lines, locate improvements, and identify easements on a parcel. Many optional items may be included in the surveys such as utilities, ground contours, wetlands, offsite easements benefiting the subject property, zoning, building setbacks and building heights. Cornerstone Engineering regularly performs ALTA/ACSM Land Title Surveys for our clients. Our staff has expertise regarding these surveys and has provided training to others on the subject of the current ALTA/ACSM Minimum Standards.
Boundary Surveys & Legal Descriptions
Cornerstone Engineering specializes in boundary surveys of publicly and privately owned property. Surveyors are experienced at doing their own title investigations using many varied sources of information.
Street & Property Vacations
Street vacations have been prepared for cities throughout California. Descriptions have been written for Caltrans remainder parcels. Cornerstone Engineering Inc. is aware of both the statutory requirements for public and private entities, as well as practical considerations of design, usefulness, changes in liability, and reservations for utilities.
CEI staff has provided surveying and mapping surveys to the local oil industry over the last 35 years for: Oxy Elk Hills, Texaco, Chevron, Petro Lewis, Occidental Petroleum, Shell Oil and several other local petroleum consultants. Our services include: Pipeline Route Surveys for both design and construction staking, Facility site grading plans and construction staking for the grading project, Lease and Facility surveying and mapping.
Cornerstone Engineering Inc. has run hundreds of miles of level loops and set permanent benchmarks for projects. The company knows how to research each separate level line, adjustment networks, and suggests the most appropriate datum and procedure for differing projects. Typical projects range from extending vertical control over twenty miles of railroad corridors in Sacramento (grades are nearly flat and rail tolerances are exacting), to setting permanent monuments by packing bags of cement to areas inaccessible by vehicle, to using portable hammer drills for setting quick and durable brass plugs in concrete in developed areas.
