Baker & Lawson, Inc. is a consulting civil engineering and surveying firm performing a variety of services in the civil engineering and surveying fields. Our staff of 23 employees includes six (6) Professional Engineers (P.E.’s), three (3) which are also Registered Professional Land Surveyors (R.P.L.S.’s).

Based in Angleton, Texas since 1965, our firm has provided design and surveying services for many transportation agencies in the general area for over 30 years. These include clients such as TxDOT, Houston and Yoakum Districts, Matagorda and Brazoria Counties, and the Cities of Houston, Angleton, Lake Jackson and Brazoria along with many other clients, both in the public and private sector.

The type of surveying services we have provided for our clients include boundary surveys for both large and small tracts, horizontal and vertical control surveys for support of aerial photogrammetry, engineering surveys for design, construction and maintenance of roadways and right of way mapping which generally includes developing a right of way map, field notes, parcel sketches and monumentation of the right of way line.

All of our firm’s surveying is done under the direct supervision of a Registered Professional Land Surveyor currently registered with the Texas Board of Professional Land Surveying. All land surveying will be done in compliance with rules and regulations promulgated by the Texas Board of Professional Land Surveying. Also, all of our firm’s work will be performed to meet or exceed TxDOT’s requirements as set forth under the Technical Analysis of the RFP. Likewise, our instrumentation will meet or exceed TxDOT’s criteria for field instrumentation as described in the Technical Analysis of the RFP.

In order to comply with TxDOT regulations and to provide safer working conditions for our survey crews, Baker & Lawson, Inc. will provide temporary signing and traffic control in and around the survey work site. The signing and traffic control will comply with provisions of the Texas Manual of Uniform Traffic Control Devices, Part VI, and will include appropriate flagging, vests, etc. This will result in a safer work site with less inconvenience to the traveling public.

Our staff of registered professional land surveyors (R.P.L.S.) has many years of surveying experience. Mr. Cecil J. Booth, R.P.L.S., will be involved in all surveying work as the Director of Land Surveying for our firm. Mr. Booth has a tremendous amount of experience in the surveying field including having accomplished many surveying projects for TxDOT, Houston and Yoakum Districts.

To further substantiate our firm’s experience and qualifications, a list of representative projects completed within the last five (5) years.

The professional staff of Baker & Lawson, Inc. includes three (3) Registered Professional Land Surveyors. These are:

The surveyors at Baker & Lawson, Inc. have extensive experience in providing surveying services to clients both in the public and private sector. Of special significance is our experience in providing various surveying services to TxDOT, both in the Houston and Yoakum Districts.

Mr. Cecil J. Booth, R.P.L.S., Director of Land Surveying for Baker & Lawson, Inc. (BLI) has been with our firm since 1974. He directs and supervises all surveys performed by our firm. He has been involved in various types of surveys for TxDOT including right of way mapping, which includes the preparation of right-of-way maps, parcel plats and property descriptions suitable for the acquisition of real property, horizontal and vertical ground control in support of aerial photogrammetry and construction, ground surveys in support of engineering design and the setting of permanent right of way markers.

In addition to Mr. Booth, several of our Survey Crew Chiefs have extensive survey party experience covering each of the various types of surveys listed above. Mr. Larry A. Sellers, Crew Chief, has been with BLI since 1972, except for a very brief period. Another Crew Chief, Mr. Ernest J. Martin, III, has been with BLI since 1989. Mr. Jerry Stefka is our Chief GPS Technician.

All BLI surveying personnel are familiar with traffic handling in or near surveying operations and are familiar with the Texas Manual on Uniform Traffic Control Devices. Mr. Booth, as well as other RPLS’s with BLI are familiar with the preparation of Traffic Control Plans should the need to direct traffic or close travel lanes arise.

Survcon, Inc. will provide Aerial Photograph & Photographic Processing. They have performed work for government entities, utility and flood control districts and toll road authorities throughout Texas.

For right-of-way projects or any other project requiring abstracting, we anticipate doing this in-house and/or acquiring the services of Postle Property Services, Inc. or other qualified professional abstractor.

All of the field and office equipment listed below is owned by Baker & Lawson, Inc.

The surveyor should make an initial on-site reconnaissance for project planning. His reconnaissance should be supplemented with USGS maps, TxDOT maps and Internet photos of the project area. He must obtain copies of existing right of way maps and public records pertaining to the properties to be surveyed. Pertinent information such as existing or proposed facilities may be available from governmental bodies, utility companies, and other consulting firms. From these documents, working sketches are drawn to be used by field personnel in their search for property markers or other features in order to locate the existing right-of-way and adjoining properties. An abstract map is prepared to identify the property owners and for TxDOT review. Permission is obtained from the land owners before entering privately owned land, preferably in writing.

A control traverse is run through project if one doesn’t already exist. If a control traverse exists, the field personnel will recover the control points and verify the accuracy of the traverse. From this control traverse field personnel will tie in property corners, Patent corners, right of way monuments, etc. as well as topographic features to supplement the existing planimetric maps. Calculations are performed to determine parcel boundary lines and existing and proposed right of way lines. A preliminary right-of-way map is then prepared.

Upon approval of the preliminary right of way map, the surveyor prepares the final right of way maps, individual parcel plats and parcel descriptions for right of way acquisition. The field personnel set permanent monuments at all baseline and right of way P.I.’s, P.C.’s, P.T.’s, 1000' stations and at all right of way intersections with property lines.

The deliverables from the surveyor consists of right-of-way map sheets, parcel plats, parcel descriptions, area calculation sheets, public record documents, and computer files of drawings (Intergraph Microstation) and parcel descriptions.

b. Horizontal and vertical control in support of aerial photogrammetry and construction.

The surveyor will coordinate and verify the route of the flight as designated on copies of aerial maps or photos. The preliminary position of the various aerial panels are determined in coordination with TxDOT personnel.

The panels are then placed in the field and field location sketches are drawn for use in preparing the final location sketches. Panels, in the form of an “X”, are painted on concrete or asphalt surfaces or are constructed from re-enforced plastic material. The material is placed flush with the surface using a color best contrasting with surface background. Center panels are usually placed near the existing roadway with wing panels being placed on each side of the center panel on side streets or private property. (Permission is obtained from the land owners before entering privately owned land, preferably in writing.) Panels in the form of a box are placed at angle points along the flight. A typical panel layout for a project would be a group of one center panel with two wing points (band) placed at approximately every 1,500 feet along the flight. The center panel will also serve as a horizontal control traverse point.

Measurements are made between panels in accordance with survey standards specified.. If previous survey control does not exist, the surveyor must establish horizontal and vertical ground control either by conventional traverse methods or by Global Positioning System (GPS) referenced to the National Geodetic Survey. Calculations are then made to determine the horizontal and vertical positions of the panel points and wing points. Location sketches are prepared for each panel point with the horizontal and vertical position documented thereon. A control location map is then prepared which shows the location of individual panel points labeled with their respective designations including bearings and distances between adjacent control points, and bearings and distances between offsite control points and adjacent control points.

Design surveys are usually made on large projects to supplement data obtained from photogrammetric methods. This often includes taking cross sections or locating features where visibility was obscured on photos by heavy ground cover, locating utilities, or measuring culvert sizes and flowlines. The baseline for a design survey may be a precise line established during a right-of-way survey or simply a line relative to an existing roadway pavement or other structures. Control points are set on a baseline at designated intervals to be used as control for cross sections, topography, and/or construction layout.

In other cases no photogrammetric information is available and the design survey is made to obtain all the design data. A control traverse and level line must be run through project if one doesn’t exist. Topographic information is obtained by conventional traversing and/or by using GPS equipment in the kinematic mode. .

Control points on large projects are usually established by a Global Positioning System (GPS) and are tied to National Geodetic Survey control monuments. Points are positioned in accordance with the overall project layout with locations being selected for visibility for GPS observations, and accessibility and visibility for further use during conventional traversing and leveling. A reconnaissance of the site must be made and supplemented with reviews of USGS maps, TxDOT maps and Internet photos of the area.

Static sessions are made and field location sketches of control points are drawn for use in preparing the final location sketches. The sessions are processed and balanced and final location sketches are drawn which document the control point horizontal and vertical positions.

Permanent right-of-way markers are usually set after new highway construction has been completed and at positions marked previously by temporary markers. The surveyor must locate and verify the locations of the temporary points intended to be replaced. Additional surveying may be required to determine the correct location of disturbed or destroyed temporary points. The positions of temporary points which have been disturbed or destroyed must be re-established from the remaining stable markers. Permanent markers consist of a brass disk affixed to asphalt or concrete by epoxy or set in concrete poured in place.
