Re: Request for Proposals to Provide On-Call Survey Support Service for All Sub-Disciplines for Professional Land Surveying and Aerial Mapping Services
Dear Mr. Garcia:
Thank you for the opportunity to present our proposal to the City of Anaheim Public Works Department Construction Services Division (City) for all sub-disciplines for Professional Land Surveying and Aerial Mapping Services. Towill is a surveying and mapping firm; this is our sole focus and has been for over 68 years. Land surveying and aerial mapping is what we do, all we do, and we do it in-house. Much of the work we provide is to municipalities and public agencies in support of their Capital Improvement Program (CIP), rehabilitation, and developer projects. We have performed many of the services within the RFP for the City on Gene Autry Way Improvements Project as a subconsultant for an engineering firm, provided monument preservation services for 96 street monuments as a subconsultant for a construction management firm, and have conducted multiple aerial imagery/LiDAR acquisition missions over the City limits as part of our on-call contract with Caltrans.
As a company solely focused on geomatics services, we attract and retain a core group of passionate survey staff and focus our investments on new survey equipment and the latest software. Towill’s key personnel who will be assigned to this contract have an average of over 25 years of professional experience in field surveying, photogrammetric mapping, remote sensing, and GIS. We take pride in designing cost-efficient technical approaches that continually meet or exceed our clients’ requirements for every project assignment.
Our goal is never to just complete a survey/mapping design task but to provide valuable geospatial information that will be used by engineers and others to improve the places where we work and live.
Towill believes that our Core Values result in repeat clients. One of Towill’s core values is the focus that is placed on providing our clients with superior services. The evidence that this core value works is shown by our high rate of repeat clients and referrals. Over 90% of Towill’s annual revenue is from repeat clients. This is a testament to our client focus, culture of client service, and overall ability to deliver on-time, first-time- right services. The City will reap the benefits of a stable, client-focused team that will work on this contract for every assigned task. So, why are we interested in this opportunity to work with the City of Anaheim? Because you provide us with the opportunity to continue to do our best work! If you have any questions, please do not hesitate to contact me at 949.261.1900 ext. 1504 (office), 612.581.8771 (mobile), or [email protected].

All Sub-Disciplines for Professional Land Surveying and Aerial Mapping Services to City of Anaheim Public Works Department Construction Services Division
2 Professional Land Surveying Services
Construction Staking/Layout
Construction staking assignments begin with our checking and verifying project horizontal and vertical control before the commencement of construction layout work. Our crews will independently survey this control, and we will provide a project control report for use by the construction staking surveyor. A review of the construction plans is completed to determine if sufficient information exists for us to provide construction staking from the plans; we also vigilantly check for errors or omissions. Our experience working from engineering plans has afforded us the insight to know when things do not appear to be in order and may need a second look.
Construction line and grade layout, whether it is for roads, sewer, water, storm drain, or grading, typically requires a swift response to avoid costly construction delays. Field crews are equipped with pre-calculated horizontal and vertical alignments so that offsets can be determined at the time of staking and so that cuts and fills can be compared to design data at the point of collection. All verification data is transferred to Towill’s database for secondary accuracy checks by office personnel.
Towill takes a proactive approach to any construction
project. The first step after receiving the construction plans is to review them and understand what needs to be built and the level of information provided in the plans.
Reviewing the horizontal and vertical controls, construction alignments, profile grades, and joins are just a few of the items that will be reviewed before putting stakes in the ground. If discrepancies are found or clarifications with the plan set are required, a Request for Information (RFI) will be prepared and submitted to the City’s representative
and/or the engineering design representative. Field checks are made to verify joins or other critical elements shown in the design plan set. Once the plans have been reviewed
and all required information is received, the area can be staked for construction.
Monument Preservation
In keeping with Section 8771 of the California Business and Professions Code, Towill recognizes how critically important accurate and enduring survey monumentation and control is to the survey operations of both the City and the surveying community. Without the perpetuation of controlling monuments, countless additional hours of field and office work can occur for both public- and private-sector projects.
Every project we undertake begins with a thorough review of not only record information but also of the proposed construction in the area. Our Project Manager organizes the investigation into existing recorded documentation with the City of Anaheim, the County of Orange, and other agencies. Records research is typically performed by the Project Manager or under his direction. From this research, a plan of action is developed for the preservation of existing monumentation and the setting of new points.
Our first step in preserving the monumentation is to determine by field verification what monuments are still in place, which have been buried, and which have been destroyed. We then advise the City of our findings and plan an operation of setting tie points, which, based on our review of the construction documents, will be established outside of proposed construction activities.

3 Monumentation will be marked with either furnished (or as otherwise specified) disks, plugs, or tags, which shall be stamped with the project manager’s California Professional Land Surveyor registration number, or as directed in each task. Monumentation shall be established or preserved for the project or project areas and shall include considerations for utility locations, proper spacing, and durability. All monuments will be field referenced with a minimum of four (4) intersecting reference points, such as cut crosses on curbs, rebars outside the work area, or other approved reference points.
A pre-construction Corner Record will then be prepared and recorded with the County Recorder’s Office for each monument. Corner Records shall include the character of the monument, its record reference, reference ties, and other pertinent data. All such field monumentation work will conform to Section 8771 of the California Business and Professions Code, which addresses the preservation of existing survey monuments.
According to the California Professional Land Surveyors’ Act, a Corner Record may be used to perpetuate, rehabilitate, or reestablish monumentation that has existed in the past in other circumstances; and, when more extensive work is required, or several monuments in the same area are in question, it may be necessary to file a Record of Survey map. Records of Survey will clearly identify project horizontal control, record map information, additional data, and lines and calls prepared in the initial boundary surveys phase.
Once a map is ready, our project manager will submit the document to the City for review and to Orange County for map checking. Any comments will be addressed, and the document will then be filed at the County Recorder’s Office for recordation.
When construction has been completed, we return to the area and determine which monuments and/or tie points will need replacement. In many instances, damage to the existing monuments is limited. In cases where monuments are to be replaced, a durable monument, as described above, or standard well monument, if required by the City, is established and post-construction Corner Records are filed. All documentation and Corner Records will be prepared to meet the requirements of both the City and the County.
Limits of removal are staked based on approved plans and/or visual inspection in the field. Our crews have enough experience with this exercise to realize when things appear to be either insufficient or excessive. If it is believed that the removal limits either exceed or are inadequate for construction, we will advise City staff.
The limits can be staked either at the actual location, such as paint on the curb, or on an offset that can be used later for construction, thereby saving time and money.
Vertical and Horizontal Control
Towill is experienced in conducting conventional surveys, monitoring surveys, precise digital geodetic leveling, and GPS static surveys, as well as establishing local project control. We have set up thousands of control networks and are well-versed in tying into and/or expanding existing control networks. Our staff has decades of experience with a wide variety of coordinate systems and the expertise to know which applies to each project.
Towill is very experienced in the performance of geodetic surveys and is familiar with working in the most current national datums; e.g., the North American Datum of 1983 (NAD83), 2011 (2010), and the North American Vertical Datum of 1988 (NAVD88). We also have a world-renowned geodetic expert on staff to lead any specialty or high-accuracy survey efforts, if needed. Towill keeps up to date with technical issues relating to the evolution of geodetic datums, geodetic surveying technologies, and associated standards and procedures.
For example, Towill is aware that the U.S. is planning to replace NAD83 and NAVD88 with a global datum such as an International Terrestrial Reference Frame (ITRF) realization. Towill can aid the City in assessing the impact of these developments and in devising strategies to deal with these events as they unfold.

4 Horizontal and vertical control is the backbone of any successful survey project. The placement of control-point locations is carefully evaluated to determine the most efficient method of performing the project tasks. Existing maps and photography, city and county maps, and available historic maps are studied to determine how to refine control-point locations to better serve each project and make the working conditions safe for the field staff. Whenever possible, the control points are located on or near roads, trails, levees, or other common routes of transportation. Special efforts are made to obtain appropriate permission to access private and/or government properties.
We regularly perform static, rapid-static, kinematic and real-time kinematic (RTK), and real-time network (RTN) GPS surveys to establish ground control, depending on the requirements for the project. We own and use Trimble dual-frequency GPS receivers. Static and fast static sessions are used to establish primary control stations; fast-static and kinematic sessions are used for secondary control. Towill is well-versed in utilizing GPS methods for establishing vertical control and deformation monitoring to various standards, including the National Geodetic Surveys.
GPS observations are downloaded and backed up daily as a precaution against inadvertent loss of data.
Baseline vectors are reduced daily in the field to check for lines that fall outside of normal parameters.
Least-squares adjustments are performed on the data, constraining the newly established control stations to existing horizontal and vertical control.
When enough baselines have been observed to form loops, a loop closure is performed to further confirm the accuracy of the baseline. Unconstrained adjustments are run to test the strength and accuracy of the entire net continuously throughout the duration of the GPS survey. After completing all scheduled GPS observations, we perform a final unconstrained adjustment and compile a report.
Upon completion of the unconstrained adjustment, high-precision network stations are held fixed together with vertical constraining stations, and a constrained horizontal and vertical adjustment is completed using TRIMNET, STARNET, or Geolab software. A geoid model such as Geoid12b is used as the underlying geoid height model to calculate accurate elevations for all points. However, we often refine these data to create a local geoid model using data gathered via differential leveling.
Preparation of Maps, Record of Survey, Corner Records, and Other Official Records Towill’s licensed surveyors are experienced at completing Records of Survey and Corner Records. They have a thorough understanding of when each document is required. A Corner Record should be used to perpetuate, establish, reestablish, and restore monumentation that previously existed in the same location. When more extensive work is required, a material discrepancy is identified, unsurveyed record division lines are to be surveyed, or numerous monuments need to be documented in a geographical area that may be disturbed, it may be more beneficial to the City to file a Record of Survey. Records of Survey will identify project horizontal control, record map information and additional data, and lines and calls prepared in the initial boundary surveys phase. Closures will be performed on all mathematical components. Once a recorded document is ready, Towill’s Project Manager will submit the document to the City for review and to the Orange County Surveyor’s Office for map checking and subsequent filing. Any comments will be quickly answered and incorporated in a revision, if necessary, and returned to the County.

5 Legal Descriptions
Towill has extensive experience and expertise in boundary and property surveys for land and parcel determination, performing tens of thousands of surveys over our 68-year history. The initial step to any successful boundary survey is performing the proper research of land records. Public records research is required to identify primary control, right of way information, and boundary lines, or lines of occupation, before performing the work. Research may be performed at city or county offices, utility agencies, title companies, or other appropriate sources. Necessary records are identified, organized, and analyzed for the field and office tasks.
Once the research is complete and all documentation associated with a boundary has been analyzed, we can prepare highly accurate calculations of where we can expect to locate monumentation associated with the boundary determination. Throughout the course of the field survey (which may utilize both GPS and conventional survey techniques), adjustments can be made to further enhance the accuracy of the search locations and minimize the amount of field time required to complete the survey. When survey results are returned from the field, they are compared to record deeds and maps, and boundary analysis is performed.
With years of experience, we can efficiently and accurately complete the boundary process, compiling an accurate and defendable survey.
Towill’s team of surveyors has the experience and knowledge to tackle all boundary surveys, from public land surveys to subdivision retracements and the establishment of centerlines. Towill consistently remains informed of changes in local, state, and federal laws on surveying and is very active in continuing education to ensure we remain current.
Boundary Control Surveys and Analysis
Towill has extensive expertise in boundary determinations, performing thousands of surveys over our 68-year history. The initial step to any successful boundary survey is proper land records research. Public records research is performed to identify primary control, right of way information, and boundary lines, or lines of occupation before performing the work. Research may be performed at the city offices, county offices, utility agencies, or other appropriate sources. This includes not only the acquisition of the public record documents and the recorded maps, but also any non-record maps and surveys that can be uncovered. Necessary records are identified, organized, and analyzed for the field and office tasks. We visit various agencies to obtain the records and use available documents to guide our field surveying and office mapmaking activities.
Once the research is complete and all of the documentation associated with a boundary has been analyzed, we can perform highly accurate calculations of where we can expect to locate monumentation associated with the boundary determination. Throughout the course of the survey, adjustments can be made to further enhance the accuracy of the search locations and minimize the amount of field time required to complete the survey.
Towill surveyors utilize a combination of GPS and conventional survey methods to obtain locations accurately and with a high degree of efficiency. Our staff has the experience of knowing exactly what procedures are right for any given situation encountered during the course of a survey. Towill’s team of surveyors have the experience and knowledge to tackle all boundary surveys, from public land surveys to subdivision retracements and the establishment of centerlines. Towill consistently remains informed of changes in local, state, and federal laws pertaining to surveying and is very active in continuing education so that we remain current. With years of experience, we can efficiently and accurately complete the boundary process, compiling an accurate and defendable survey.

6 Topographic Mapping
Towill regularly performs field topographic surveys
using both GPS and conventional surveying equipment
and techniques. Towill also utilizes various CAD
platforms, including AutoCAD Civil3D, and will deliver
mapping products in formats requested by the City to
your standards. Topographic surveys are typically
performed to produce a detailed map for engineering
design or as supplemental data collection to enhance
and complete photogrammetric mapping. However, we
have experience performing virtually every type of field topographic surveying task. We will make it a priority to meet with City staff before commencing any design
surveys, to ensure that the correct level of detail is
achieved and that we are providing meaningful
information to the end-user of this data.
Recently, Towill provided detailed design surveys to the City of Moreno Valley to support Cycle 1, Safe Routes to School. Both hard copy plan sheets and AutoCAD Civil3D design files were provided to the City so that the City could complete the engineering design. Towill is also currently providing topographic design surveys to the City of Long Beach for various parking lots along the City’s beaches.
Terrestrial and Mobile LiDAR Scanning
The Towill team brings 17 years of terrestrial LiDAR scanning experience. Terrestrial LiDAR scanning can be used to obtain spatial information for features that require a high level of detail or are difficult to reach. It can also be used to gather many data points on complex surfaces, such as rough and uneven ground. The key to successful terrestrial LiDAR scanning technology is knowing when it is the right tool for the job, how to establish control to provide predictable precision within accuracy specifications, and how to combine and augment it with other measurement methods and data products to provide the most efficient service for the tasks at hand. In addition, Towill’s unique business model, which combines complete aerial photogrammetric and LiDAR services, as well as ground-based field surveying augmented with LiDAR, brings a comprehensive mapping tool-set to this contract.
Recently, Towill completed 16 miles of detailed topographic mapping along State Route 91 in Riverside County, utilizing a combination of mobile and terrestrial LiDAR, aerial photogrammetry, and conventional ground surveys. This seamless integration of various advanced and conventional technologies allowed the Towill team to complete this design-level mapping project to Caltrans standards within 120 days. This is a strength the Towill team will bring to the City.
As-Built Surveys and Subsurface Utility Engineering
Towill is a full-service surveying and mapping company and will perform all services described in the RFP except for utility potholing, which will be performed by our subconsultant, AirX Utility Surveyors, Inc. (AirX).
Surveying existing utilities and other surface-visible structures is a common requirement for topographic mapping and one in which Towill excels. Typical tasks in this category could include creating an as-built utility base map from field surveys and/or existing record utility research. All field surveys will be subject to a set of quality control measures developed to minimize and/or mitigate field errors. Additionally, for surveys that require locating and identifying existing buried utilities should it be necessary, Towill has experience

7 managing the application of a variety of non-intrusive electronic exploration methods as well, such as magnetic scans and ground-penetrating radar. Research will be performed with utility surveyors to acquire information usable in planning field surveys and interpreting the resultant data. Compilation and display of the information will be performed following City requirements, field-checked, and incorporated into the project deliverables.
On many of our construction projects, we record the location of the improvements “as they are built” during construction. The final location of construction improvements such as sewer/water pipes, overhead transmission lines, rail/road/marine infrastructure, etc. can be different than the original design location.
Providing an as-built survey provides a detailed record-drawing document of the constructed item(s) and their associated surroundings.
Traffic Control
Towill is knowledgeable of traffic control procedures and will work with the City so that safety and regulated concerns are met with each task.
Towill has the required traffic control equipment for jobs involving moderate traffic, and when conditions demand the highest levels of safety and control, flaggers with paddle boards can be employed.
Traffic control will be performed following the Work Area Traffic Control Handbook (WATCH) Manual, Manual on Uniform Traffic Control Devices (MUTCD), or as required by the relevant governing agency. Towill’s staff is highly experienced at working safely near roadways, railways, and traffic and following the proper protocols.
Technical Review of Mapping
Due to our team’s history with the subdivision process throughout California, our team is well-versed in the Subdivision Map Act and its processes and knows what to look for when reviewing the work of others. Upon obtaining the Conditions of Approval for a subdivision, we will make a checklist, along with all state, county, and city standard requirements to complete a thorough review. Our staff has the experience necessary to examine a map quickly and accurately to provide the City with a review that is complete and thorough the first time, to avoid unnecessary delay in plan checks. A complete record of all submitted items and the corrections requested is kept to aid in the review of further submittals. It is always recommended that a meeting be held with the submitter along with City staff to review the corrections so that the process can move along smoothly. While these meetings are not always necessary, they can prove helpful in providing experience to the submitters and to City staff.
In addition to final maps and parcel maps, we also have experience checking and verifying lot line adjustments, legal descriptions and plats, and other survey reports and documents that are required for a specific project. All map, plan, and document checks are performed personally or under the direct supervision of a Professional Land Surveyor licensed in the State of California. All check letters will be signed by said surveyor and all plan checks are prepared promptly in keeping with the Subdivision Map Act.
Easements and Vacations
These items all require similar services to review the existing property and property rights and to prepare the necessary documents to complete the acquisition process. Towill can produce legal descriptions and plats for property interest conveyances, record of survey maps, attachment documents and exhibits to accompany parcel map waivers, certificates of compliance, right of way engineering, appraisal maps, ALTA/ACSM land title surveys, and special exhibits including property mapping for presentation or clarifying property-related issues, associated improvements, and other relevant features of interest to real estate professionals and attorneys.

8 Aerial Mapping Services
Aerial Topographic Mapping
Our clients have discovered that the interpretative power of a photograph combined with the accuracy of a map is a valuable combination. Orthophotos are a required deliverable on nearly every aerial surveying project undertaken by Towill over the last 15 years. Towill has developed special image processing techniques which combine many individual aerial images onto a seamless mosaic. Many of our projects require us to ortho-mosaic hundreds of individual aerial photographs to create a seamless image of the entire project area. This is typically tiled to create files that are of a manageable size in uncompressed GeoTIFF format, with full-project mosaics created using MrSID. We also frequently deliver imagery in JPG or ECW formats. We are aware of small but subtle differences in the imagery headers that can affect correct georeferencing of the imagery in various software packages, including MicroStation, Autodesk Civil3D, and ESRI ArcGIS. The majority of the orthophotos produced are delivered as natural-color imagery. Towill has also produced imagery with NIR, CIR, or Thermal bands as requested. Our medium-format PHASEONE digital camera that is co-located with our airborne LiDAR sensor for simultaneous acquisition of LiDAR data and aerial photography also collects the NIR band in addition to the natural-color bands (RGB), allowing us to easily produce 4-band orthophotos. With the addition of small Unmanned Aerial Systems (sUAS)-acquired imagery, we now have the capability to produce images with even smaller resolutions.
Restricted Airspace – Disneyland Theme Park
We are confident that the City is aware of the
Temporary Flight Restriction (TFR) issued by the
Federal Aviation Administration (FAA) issued
October 27, 2014, in the Notice to Airmen
(NOTAM) number FDC 4/3635. Under this NOTAM,
the FAA classifies the defined airspace as ‘National
Defense Airspace’ which includes an area with a
radius of 3 nautical miles centered on the Anaheim
Convention Center beginning from the surface up
to and including 3,000’ Above Ground Level (AGL).
Access to this airspace requires applying for an FAA
airspace waiver. Towill has direct experience with
the waiver process and has successfully applied for
and gained access to this airspace for several of
our on-call Caltrans projects. For additional
information on NOTAM 4/3635 please see

9 Photographic Imagery
Towill offers in-house aerial photogrammetric
services and utilizes a well-developed network
of reliable, regionally based aerial photo and
flight service subcontractors to support us
based on the specific type of equipment they
offer and their geographic location. Towill can
provide sUAS as well as fixed-wing and
helicopter acquisition services through our
network of flight subcontractors. Towill
manages and fully plans all aspects of the
aerial photo missions, including establishing
the ground control, camera specifications, photo scale, flight line design, etc. Once the photo mission is fully planned and designed, we will supply the flight team with a TRACK AIR-formatted mission data file for uploading into their flight mission planning software. Photogrammetric mapping represents a very important business line for Towill, accounting for an average of 35% of our company’s annual revenue. Digital orthophotography is a standard deliverable for more than 95% of our photogrammetric mapping projects.
Our clients have discovered that the interpretative power of a photograph combined with the accuracy of a map is a valuable combination.
Airborne LiDAR
Towill has decades of experience performing airborne LiDAR mapping projects. We have completed several thousand square miles of LiDAR data collection throughout the length and breadth of California. Several important features of our approach to airborne LiDAR data collection include calibration of the entire LiDAR system; ground control points; use of sophisticated software to identify, segregate, and remove points that do not represent the ground; and the use of aerial photography to verify the accuracy of the LiDAR digital elevation models.
We have recently completed aerial LiDAR acquisition and mapping for more than 1,185 square miles in two separate areas in San Bernardino County. The project was completed for the Flood Control District with final deliverables including Digital Elevation Models (DEM) and GIS metadata.
Towill owns and operates one Teledyne/Optech ALTM Galaxy T2000 LiDAR system, one Teledyne/Optech ALTM M-300 LiDAR system, two PhaseOne 4-band 100MP aerial camera systems, and two UAV systems.
Eye safety is a high priority during LiDAR data collection. Our sensors are programmed to prevent the laser from firing when the range to the target drops below the preset value that has been established as the minimum range for eye safe operation, which differs from the altitude, as the sensor transmits the beam to the target at an angle.

13 City of San Diego, As-needed Land Surveying Services, San Diego, CA Towill was awarded an as-needed land surveying consultant contract through the Public Works Department in support of the Land Surveying Section. The City had amassed a significant backlog of Capital Improvement Projects (CIP) and sought to increase its capacity through direct land surveying contracts.
Design and Topographic Surveys for Capital Improvement Projects Towill has been awarded a total of 18 task orders comprising survey support for street and utility rehabilitation engineering projects across the City. These CIP project surveys begin with a record map and document review of the preliminary files provided by the City, followed by additional record map and document research (including quasi-public and private survey records) when necessary.
Next, field surveys are conducted to identify and measure existing survey monumentation (horizontal and vertical control as well as boundary including non-record monuments of historical value and significance) with a standard of care adhering to the City’s minimum accuracy standards for control and boundary measurement (GPS and Total Station).
The field data and notes are reduced and right of way lines are resolved and checked by professional survey staff to provide the foundation for the engineering drawings. Design and topographic data are then collected per the City’s mapping standards (data collected using City topo codes and processed through MicroStation and InRoads software). This data includes but is not limited to the following features required to support engineering analysis and design: pedestrian ramps, curbs, gutter, paving sections, drainage structures, wet and dry utility location, striping, signage, lighting, traffic signals, and other fixed works located within and adjacent to the public right of way. Towill works directly with the Land Survey Section staff to tailor the deliverables to meet the department’s needs.
Street Survey Monument Rehabilitation Projects
Towill has been awarded three task orders to provide
specialized services to repair existing street survey
monuments that had become damaged and constituted road
hazards. The existing condition of these monuments varied from cracked frames and broken lids to new rings improperly welded and broken free from the original frame. Towill
performed site visits to document and photograph the existing condition of each monument and address access, safety, and traffic control considerations. Towill worked together with a subconsultant to develop, submit, and execute traffic control plans, perform the site demolition, preparation, frame
welding, and concrete encasement of these monuments in 24 to 48 hours (total time on each site), completing each task within seven business days upon approval of traffic control plans. This approach to providing a specialized service simplified and streamlined the process to accomplish the needed repairs by performing the work through the as-needed services contract rather than routing through the City’s Public Works Department’s internal process.
Task orders under this contract have been completed on schedule.

15 Los Angeles County Department of Public Works, As-needed Surveying and Mapping Services, Los Angeles County, CA
Under a multiple-year, as-needed surveying and mapping services contract, Towill provided mapping for multiple task orders for projects located throughout Los Angeles County. With each task order, county staff provided Towill with the mapping limits and other project specifications such as map scale, contour interval, and orthophoto resolution. Towill developed a photo control survey plan and submitted this plan back to county staff who performed the field survey work. Once all aerial panels had been set, county staff notified Towill that the job was ready to fly and we mobilized the flight crew. Task orders involved mapping various types of terrain, including deserts, rugged mountains, and coastal plains, as well as extensive urban development areas.
87th Street East and 90th Street East Bike Lane
Towill provided mapping for approximately four miles of 87th Street East and 90th Street East near Sun Village in Los Angeles to support the design of bike lanes. The mapping consisted of a 120' strip for approximately 22,000 linear feet of roadway. The ground control was placed, surveyed, and targeted by the County of Los Angeles. The mapping was centered along the existing roadway. The mapping produced for this task was at a scale of 1" = 40' with a 1.0' contour interval. Natural color digital orthophotography was also produced. Achieving well-balanced orthophotography was a challenge—the mapping corridor was extremely monotone, as would be expected in the desert. The mapping was delivered in MicroStation design file format, conforming to the County of Los Angeles’ CAD standards.
Public Works Headquarters Renovation
Towill prepared an ALTA and Record of Survey for the
LACDPW Headquarters facility in Alhambra. The project
included the creation of a base map of the facility using photogrammetric mapping techniques at 1"=20' and the
development of a Digital Terrain Model (DTM) sufficient in detail for generating 1.0' design contours. This base map was supplemented as necessary with field
topographic surveys to meet the requirements of an
ALTA/NSPS Land Title Survey. In addition to the ALTA, a Record of Survey was prepared and submitted to the
County of Los Angeles for review and recordation. The
field crew revisited the site to tie in property corners and to identify some of the features collected but
unidentifiable from the aerial imagery.
Task orders under this contract have been completed on schedule.

17 California Department of Water Resources, On-call Land Surveying Services, Statewide, CA Under a multi-year on-call land surveying service contract, Towill provided a wide range of land surveying and mapping services supporting the mission of the California Department of Water Resources (DWR). Towill was the leading provider to DWR of aerial photogrammetry and airborne LiDAR services and was responsible for these services on more than 100 task orders since January 2016 and was recently selected for a new contract.
Lake Perris Dam Seismic Retrofit Project
Lake Perris is the southernmost State Water Project Facility and the southern terminus of the California Aqueduct. DWR identified potential seismic safety risks in a section of the foundation of Perris Dam. Towill provided a variety of surveying services, including horizontal and vertical control verification, as-built surveys, construction layouts, earthwork quantity surveys, 3D laser scanning, digital terrain models, and quality assurance surveys.
Due to the age of the design survey data, changes to the site had occurred since the data was obtained. To capture and delineate these changes, we developed an as-built digital terrain model of the dam surface repair area. Since the rock blasting area was difficult to access with conventional survey methods, we determined that utilizing 3D laser scanning to collect the data was the best solution.
This enabled us to provide a rapid turnaround on monthly quantity verification—the quantity results were measured and reported within 24 hours of the request. We also developed a field-to-finish system to expedite the processing and reporting of field survey data.
Geodetic Control Network, LiDAR, and Orthoimagery for the State Water Project Towill worked with representatives of DWR’s Geodetic and O&M Branch to design a survey approach for inventorying more than 750 miles of rivers, reservoirs, canals, and pipelines which comprise the State Water Project. This project was separated into two phases. Phase 1 included approximately 220 miles of the California Aqueduct, and Phase 2 included approximately 530 miles. The objective of the project was to produce color orthophotography, digital terrain models, and horizontal and vertical ground control at one-mile intervals over the extent of both phases.
The survey control network was established utilizing existing DWR subsidence monitoring benchmark monuments located at one-mile intervals along the length of the project. GPS surveying technology was used to accomplish the control survey. Airborne LiDAR data was captured using rotary and fixed-wing aircraft. The LiDAR data was acquired at a nominal density of nine points per square meter. Natural-color (RGB) aerial imagery was acquired concurrently with the LiDAR flights (simultaneous acquisition). The LiDAR data was used to generate digital elevation models (DEMs) for use with GIS and triangulated irregular network (TIN) surfaces for use with CAD. Finally, controlled aerial photography was used to develop natural-color digital orthophotography covering the project corridor.
Task orders under this contract have been completed on schedule.

20 Additional Information and Description of Resources
Towill understands that tasks from this on-call professional services contract will be assigned by the City through a task order process. Towill approaches each task order received as unique, which is why we develop a specific plan that is tailored to meet project criteria, such as completion date, budget, forms, format, safety concerns, environmental issues, permits, rights-of- entry, methods of access, travel, and final deliverables.
Towill’s Account/Project Manager, James Rios, PLS, will serve as the single point of contact and will meet with and communicate with the City and discuss each specific request for surveying services. This approach has earned Towill an excellent, well-known reputation for anticipating and resolving problems before mobilization. The figure to the right demonstrates the proposed process for each task order beginning with the survey request and draft task order, preparation of the cost proposal, communication and discussions with City management and staff, to submission of the final task order and cost estimate. We believe this proven process will be key to successfully delivering task orders.
Upon approval of the task order, the team will hold a kickoff meeting where the focus will be on delivering a consistent, efficient, and quality product.
Instructions to the project team will be developed and distributed to all team members. These instructions may include communication protocols, critical path schedules, budgets, technical standards, scope of work, required deliverables, and quality control plans and procedures.
Work Plan and Quality Control Plan Preparation: James and appropriate key personnel will develop a project work breakdown structure and quality control plan that will provide an approach to meet or exceed the specific task order criteria. They will follow the California Land Surveyor’s Act, California Subdivision Map Act, City standards and specifications, and professional land surveying standards for those areas not covered by the acts and standards. The specific approach will include, at a minimum, survey and mapping methodologies, equipment and software to be used, schedule and associated milestones, deliverable requirements, health and safety concerns, and budget. The work and quality control plans will be reviewed with the City and any necessary adjustments will be made to incorporate concerns.
Project Kick-Off Meeting and Status Meetings: Once the City issues a Notice to Proceed (NTP) to Towill, any required meetings and discussions to review the scope of work, methodologies, interim deliverables, contract requirements, and final deliverables will be scheduled. James will finalize the work plan and assign Towill resources for the necessary personnel and equipment to meet the task order requirements. The City has our commitment that resources will be mobilized quickly so that project schedules are met. Towill is fully capable of performing multiple mapping and surveying activities concurrently throughout the life of the contract.

21 James will review the progress of all active task assignments with the City at an interval acceptable to the City to discuss budget, schedule, and milestone deliverables. These meetings will continue as necessary through each phase of the project until the final deliverable package has been reviewed and released to the City.
Planning and Managing Resources, Costs, and Schedules: To assist our management staff in tracking project costs and resources, several types of customized reports are generated by Towill's accounting department. The information contained in these reports is obtained from daily time sheets completed by all staff and from contract records. This timely process allows managers to closely track, examine, and analyze project costs in detail weekly. The advantage of this process is that we can quickly identify and address potential problems and make any necessary adjustments in our production processes and our allocation of resources to keep costs under control and the project on schedule. Towill’s staff is used to rapid mobilization and overtime/weekend work when projects accelerate.
Reporting: Towill requires all project managers to maintain an accurate and easily understandable record of the project as part of its general business practice. The activities of office and field staff are tracked and managed through regularly maintained timesheets that become part of the job record. It is our standard practice to submit a Monthly Status Report in a format customized to meet each client's specific needs and detail requirements. Each Monthly Status Report typically provides a summary of 1) the status of all active work on a project and/or contract, 2) work anticipated to be accomplished in the next reporting period, 3) challenges and proposed solutions, and 4) adherence to budgets which provides a status of all active work and their components.
Project Completion: No deliverable will be released to the City in final format until James as Account/Project Manager and Jake as QA has reviewed all elements and authorized its release. For ease and expediency during all phases of the project, as well as the final release to the City, all data can be transmitted digitally or in person, whichever method is preferred by the City. Follow-up will also be performed by our Project Manager to ensure the complete satisfaction of the City and to adjust the approach and implementation for each project phase, or task order, based on the lessons learned.
First-Time-Right Deliverables to the City: We believe quality assurance/quality control (QA/QC) is solely the consultant's responsibility. Our clients should not be burdened with performing time-consuming quality checks to verify that the deliverables meet their expectations. To eliminate costly corrections and revisions, Towill approaches quality control with the premise that it is best to perform quality verification at all stages of planning and technical task execution. Please see our Quality Control/Quality Assurance Program narrative beginning on page 23.
Survey Safety: Towill places primary importance on the safety of our employees and the public. We are very experienced at working safely near roadways, railways, and traffic. Our commitment to safety begins with each new hire; new employees are immediately given safety orientation training. Management training is given to all staff with responsibility for employees, from supervisors to the managerial level.
We incorporate relevant safety concerns in our Daily Work Assignment Sheet. We have site-specific safety meetings to discuss safety and investigate hazards for the particular site. Additionally, many of our field staff are E-Rail Safe Certified, and we conduct (and document) daily Job Hazard Analysis forms on a digital application as well as conduct bi-weekly Tailgate Safety Meetings.

23 Quality Control/Quality Assurance Program
Quality starts with excellent project management. Towill’s project management methodology for virtually all project undertakings can be simply characterized as a step-by-step process or what is commonly referred to as Critical Path Method (CPM). All survey and remote sensing projects consist of numerous independent activities that interact in a complex manner. Towill’s project management team utilizes this step-by-step technique to define those activities that are both critical and non-critical (work breakdown structure), the time required for their completion, and how each activity is related to the previous and next activities.
Ultimately, this methodology serves to define and allow for the efficient scheduling of each activity, thus ensuring the successful on-time completion of the project.
In addition to the project management method described above, one of the key elements of the Towill approach to project management is the importance placed on communication. This approach is firmly centered on frequent and efficient communication with our clients during each phase of the project. We understand that the difference between a successful project and one that falls short of expectations is often the result of a breakdown in communication.
Towill acknowledges the need to provide direction and facilitate effective day-to-day communication to create a seamless and cost-effective approach to the completion of all project undertakings. Towill has the right combination of management depth and technical expertise that ensures our clients will receive the highest quality service, cooperation, communication, and data deliverables. Moreover, our staff understands that consistent project support is imperative in not only earning but also retaining trust with our clients.
Effective project management at Towill begins with a qualified team and an efficient organizational structure. The key element in the organization of a project of this size is the chain of accountability. The second element required for effective and successful project management is a detailed Project Plan. On larger project assignments Towill will prepare a Project Plan that describes:
Inspection schedules, deliverables, and key production milestones Quality Control procedures for all work and review phases Deliverables and Acceptance Criteria
Communication strategies
Potential risks and risk mitigation
Towill recognizes that contracted deliverables that meet the specifications are the key element to successful performance on every project assignment. The ability to provide such deliverables is documented through our satisfied clients. We place utmost importance on adhering to project specifications and our quality control procedures. Our philosophy is to ensure on-time delivery of services that meet our client’s requirements. We emphasize quality control from the initial proposal preparation and submission through the final delivery and acceptance of finished deliverables. In-process production reviews ensure accuracy and completeness during the production process and eliminate corrections and production delays.
Towill subscribes to the Plan, Do, Check, Act principles of Quality Management.
1. We establish a comprehensive Quality Management Plan for each project that includes specific data definitions, rules, and a comprehensive deliverables checklist.
2. We Do the work according to our Plan.
3. We Check our work to determine if it is consistent with our Plan.
4. We Act to modify our work and update our Plan when and if necessary.
