City of Santa Ana RFP No. 19-090
<br />Professional Land Surveying Services
<br />piling an accurate and defendable survey.
<br />Towill's team of surveyors has the experience and
<br />knowledge to tackle any and all boundary surveys,
<br />from public land surveys to subdivision retracements
<br />and establishment of centerlines. Towill consistent-
<br />ly remains informed of changes in local, state, and
<br />federal laws pertaining to surveying and is very active
<br />in continuing education to ensure we remain current.
<br />When locations are returned from the field, they are
<br />compared to record deeds and maps, and the bound-
<br />ary analysis is performed. With our years of experi-
<br />ence, we can efficiently and accurately complete the
<br />boundary process, compiling an accurate and defend-
<br />able survey.
<br />According to the California Professional Land Survey-
<br />ors' Act, a Corner Record may be used to perpetuate,
<br />rehabilitate, or reestablish monumentation that has
<br />existed in the past in other circumstances; and, when
<br />more extensive work is required, or several monu-
<br />ments in the same area are in question, it may be
<br />necessary to file a Record of Survey map. Records of
<br />Survey will clearly identify project horizontal control,
<br />record map information, and additional data, and lines
<br />and calls prepared in the initial boundary surveys
<br />phase. Once a map is ready, our project manager
<br />will submit the document to the City for review and to
<br />Orange County for map checking. Any comments will
<br />be addressed, and the document will then be filed at
<br />the County Recorder's Office for recordation.
<br />These mapping items will be prepared in accordance
<br />with the California Subdivision Map Act, California
<br />Professional Land Surveyor's Act, California Public
<br />Resource Code, and the City of Santa Ana Municipal
<br />Code. These items will be discussed with the City
<br />and/or County agency where the property is situated.
<br />The anticipated deliverables for this item will vary
<br />depending on the requested subdivision mapping task
<br />requested.
<br />Map Checking Services
<br />Towill's team of professional surveyors are well qual-
<br />ified to perform map checking services for the City.
<br />In fact, the greatest testament to our expert working
<br />knowledge is that we are currently performing the
<br />exact same map checking as those noted in the
<br />City's RFP for the City of Fremont as well as Alameda
<br />and San Mateo Counties. We also served as a map
<br />T TOWINLL
<br />checking subconsultant to MSN Engineering for their
<br />on -call contract with the City of Pasadena. Our experi-
<br />ence includes but is not limited to the preparation and
<br />review of parcel maps, tentative maps, subdivision
<br />maps, records of survey, and annexation maps.
<br />When preparing maps to support the division of land,
<br />knowledge of the Subdivision Map Act (SMA) is criti-
<br />cal. Subdivision and other related maps begin as any
<br />other boundary survey would, with research, field sur-
<br />veys, and boundary line determinations. Understand-
<br />ing the intent of the map guides the next step, where
<br />new lines may need to be determined for parcel splits
<br />or site features may be located to support a lot line
<br />adjustment or encumbrance map.
<br />Construction Staking
<br />Construction staking assignments begin with our
<br />checking and verifying project horizontal and vertical
<br />control prior to the commencement of construction
<br />layout work. Our crews will independently survey this
<br />control, and we will provide a project control report
<br />for use by the construction staking surveyor. When
<br />ground surveys, such as field quantity verification,
<br />subsidence, layout verification, or utility relocation
<br />surveys, are needed, all resulting data is smoothly
<br />integrated into final as -built or as -verified reports.
<br />A review of the construction plans is completed to
<br />determine if sufficient information has been provid-
<br />ed for us to perform construction staking from the
<br />plans; we also vigilantly check for errors or omissions.
<br />Missing information is tabulated and presented to the
<br />City for their review. When we see things that do not
<br />look right, our first step, upon review by the Project
<br />Manager, is always to alert the City. While we are not
<br />engineers, our experience with working from their
<br />plans has afforded us the insight to know when things
<br />do not appear to be in order and may need a second
<br />look.
<br />We regularly perform surveys to support the construc-
<br />tion of a wide range of projects for both public and
<br />private entities. Typically, the staking plan will be laid
<br />out in AutoCAD or other software if specified by the
<br />client. The project manager conducts a site reconnais-
<br />sance, coordinates with the client, and finalizes the
<br />field crew's action plan.
