Project Highlights: Experience with the City of Santa Ana

BRISTOL STREET WIDENING PROJECT
Leighton performed a geotechnical investigation for Phase I of the Bristol Street Widening Project, extending from Pine Street to McFadden Avenue, a 4,300-foot-long segment consisting of at least two lanes in each direction. Leighton’s subsurface investigation involved hollow-stem auger borings drilled to a maximum exploration depth of 5.5 feet below the existing pavement surface. Bulk soil, asphalt, and aggregate base samples were collected. Laboratory tests consisted of R-value and moisture & density, and were performed in conformance with ASTM procedures.

WARNER INDUSTRIAL PARK AREA 1 AND AREA 2 PAVEMENT REHABILITATION Leighton completed a geotechnical exploration for pavement rehabilitation of 17,800 linear feet of primary two-lane streets within the Warner Industrial Park. The exploration consisted of 20 borings, pavement condition surveys, and non-destructive pavement deflection testing.

Laboratory testing program included tests on representative samples for in-place dry density and moisture content and R-value. Based on the results of our exploration, laboratory testing and geotechnical analyses, we recommended three alternatives for pavement reconstruction.

4 d. Understanding of Need
Our goal for every project is to deliver a technically excellent work product that achieves optimal benefits for the City. Key to achieving this goal is effective communication with the City and all stakeholders throughout the course of the project. We find that client input is invaluable in streamlining our processes and developing recommendations that attain a client-specific balance between what is ideal and what is cost-effective. As such, we will initiate and maintain close coordination with the City and, if desired, ensure that all work products are initially submitted in draft form to solicit input from City staff before finalization.

Effective Communications and Staffing Cost Controls
The Leighton Team will hold internal weekly management meetings to forecast our personnel resource utilization. We discuss current workload and anticipated “notices to proceed” for all on-going and new contracts. As part of this management, we will be communicating with the City so we understand and anticipate specific task orders. This allows us to ensure staff continuity through each project as we greatly understand the value of personnel continuity for each specific project.

All of our offices are interconnected Microsoft Teams to allow for all of our staff to work effectively on projects regardless of where the work is. GIS/CADD functions are centralized for improved productivity and reduced costs. This benefits the City in that we can efficiently work on your projects regardless of location, and we can quickly mobilize to meet your schedules. Further, data can be rapidly posted on our secure web-based client portals.

Supported with our deep bench of California-licensed professionals here in southern California, we will also be prepared to respond to your needs on short notice -- such as natural disasters and emergencies; as we have in the past. We can provide the City a specific on-call 24/7 telephone number.

Using real-time accounting, our Project Managers can have a snapshot of costs at any time (typically daily).

Project Managers will work closely with the City to manage costs, and keep City personnel informed about our progress and remaining budget for a given project. We will not exceed an agreed-upon budget without prior written notice from appropriate City personnel. To the extent desired by the City, we will also communicate with you to keep you aware of our progress on Task Orders, including schedule and budget projections (as appropriate).

Project Management
Leighton uses MetaField as a networked and integrated Field Information Management System (FIMS) and Laboratory Information Management System (LIMS). This eliminates the need for paper in the field, laboratory and/or office; although we produce printed copies of any documents you need or want, at any time. Our field staff is equipped with company-provided cell phones, networked laptops, tablets and wireless (Bluetooth®) printers for those regulators and clients who still require paper. This system allows us in real time to email data typically as a PDF, or post data on a web page for your independent and secure access.

Field staff will be mobilized from our nearby Irvine office, with support from our other Southern California offices, as needed. Field staff personnel are dispatched using MetaField, which e-mails their assignments to their phone and/or tablet, so they can see the site location, site-specific contact persons, and prior data acquired for that site. All data acquisition is stored and transmitted electronically, using a secure cellular network and the Cloud. Field staff either accepts or declines assignments based on their current work backlog, and scheduling is viewed on a MetaField calendar for project managers to review and coordinate.

Quality Control/Quality Assurance
Diligent quality control and quality assurance are essential for the technical excellence of engineering services and reports. Leighton’s quality assurance program consists ultimately of principal review of all deliverables before submittal to our clients, a practice long proven to be successful. Accordingly, the success of our quality Leighton uses MetaField to
eliminate unnecessary paper
and provide you real time
data from the field, all in one
secure location.
5 control program rests upon the integrity of our principal engineers and geologists. In this regard, our bench of principal professionals has demonstrated unwavering commitment to quality and professional integrity through their long tenure with Leighton.

On each project, Leighton employs several layers of quality assurance procedures to ensure adherence to the project’s goals, budgets, and schedules, and to maintain the highest quality technical data. Budget status, work progress, and the results of data collected in the field are conveyed in regular communication from Leighton’s Project Manager to the City’s designated point(s) of contact. Through constant monitoring of project costs, schedule, and results, and through clear communication with the City, Leighton minimizes change orders throughout the duration of each project to its completion.

Documents for agency submittal, including their associated tables and figures, undergo a two- to three- tiered internal review, depending on size and complexity. Data tables and figures are initially drafted by junior staff under the guidance of the Project Manager. Once complete, these work products are combined with the report text to form a complete document for review by the Principal in Charge. The QC officer checks both the data points and the broader conclusions of the report prior to submitting a draft report to the City for review.

Our quality control approach includes the following steps as illustrated in the accompanying flowchart. • Identification of specified task objectives
• Selection of qualified personnel for specified tasks
• Compliance with field procedures, as documented in Leighton field procedures manual • Selection and application of systematic data acquisition and analysis techniques • Review of data during the project to conform appropriateness and adequacy of techniques in meeting task objectives
• Application of quality control measures during data collection and analysis • Formal project review in which conduct and the work products are critically reviewed and evaluated by senior personnel who have extensive experience and seasoned judgment • Documentation of the Above Terms
• Documentation of the above items

The Geotechnical Process
6 e. Relevant Project Experience
Leighton has provided On-Call services for Geotechnical Engineering Services for various cities and public agencies across southern California. The list below highlights some of this experience in the past five years.

Client Reference information for all of the client projects listed below are provided in section “g. References.” Various Geotechnical Engineering Services
ORANGE COUNTY PUBLIC WORKS | SANTA ANA, CA
BREA BOULEVARD CORRIDOR IMPROVEMENTS | 2017 -
PRESENT: Leighton was selected competitively to provide geologic and geotechnical services for the widening of Brea Boulevard through Brea Canyon. The road widening will
extend approximately 1.75 miles from Canyondale Drive to the Los Angeles County line.

The project includes replacing three bridges; construction of earth retaining systems; extending several culverts; and construction new pavement sections. Bridge design was
performed in accordance with AASHTO LRFD Bridge Design
Specifications with Caltrans Amendments along with Caltrans Seismic Design Criteria. Earth retaining systems include conventional semi-gravity cantilever walls, internally reinforced systems including mechanically stabilized earth (MSE), earth anchor, soil nail and segmental block walls. Alignment of the road will also require the evaluation of slope stability for temporary excavations and permanent cuts. Pavement section design will be performed in accordance with the Orange County Highway Design Manual.

ORANGE COUNTY ZOO LARGE MAMMAL EXHIBIT | 2021 -
2022: Located towards the back of the zoo in the new Oak Woodlands habitat, the new large mammal exhibit consists of three new buildings: the Holding Building, Auxiliary Holding Building, and LSS-Kitchen Building.

Working closely with the architect, our field exploration consisted of six borings to a maximum depth of 22 feet, a geophysical survey to support liquefaction analysis of the site, and a field percolation testing. We evaluated the soil characteristics, including expansion potential, corrosivity, shear strength and shear wave velocity, and geologic hazards at the site such as ground rupture, lateral spreading, and seismically induced settlement. Based on results of our analyses, we developed recommendations for design and construction of the project.

During construction, we provided geotechnical observation and testing to confirm that placed fill was suitable for the support of foundations and floor slabs of the buildings and for the bioswale/filtration basin. We met with the general contractor, the County’s arborist, and the grading operator when it was discovered that existing tree roots were in the path of proposed overexcavations, and that building and retaining wall footings would encroach underground drip lines for two oak trees and one pine tree.

Special inspection and materials testing were performed during construction of the three buildings, bridge, cages, and canopy. Our tasks included special inspection and testing of reinforcing steel, concrete and masonry, ACI certified shotcrete, high-strength grout, ICC field welds, high-strength bolting, material identification verification of hardware, anchors and epoxied anchors and dowels, and shop NDT ultrasonic for complete joint penetration (CJP) welds.

7 Central Jail Complex – Multiple Projects
ORANGE COUNTY SHERIFF -CORONER DEPARTMENT | ORANGE , CA Working under an on-call contract with OCPW, Leighton provided geotechnical and/or materials testing services for a number of Orange County Sheriff-Coroner Department’s (OCSD) projects at the Central Jail Complex (CJX) in Santa Ana.

We provided on-call geotechnical engineering support, and observation and testing to confirm that placed fill materials including soils and aggregate base were suitable for the support of foundations, floor slabs, and new vehicular/pedestrian pavements. Observation and testing services were also provided during utility trench backfill operations and during asphalt paving operations. Engineering support and consultation provided by our onsite soils technician included remedial grading recommendations where loose or unsuitable soils for improvement support were encountered.

Katella Facility Upgrades
ORANGE COUNTY SHERIFF’S DEPARTMENT | SANTA ANA, CA
| 2019 – 2020: The Katella Range Upgrades project
encompassed construction of a roof over the uncovered
portion of the Range as well as expanding the Range to the north and south of the existing building footprint. The roof structure was constructed of structural steel with tapered steel girders and wide flange beams. The expanded area was
enclosed by concrete masonry unit (CMU) walls, supported by reinforced concrete footings.

Leighton performed a geotechnical exploration for the
proposed improvements to evaluate the subsurface soil
conditions of the site and percolation testing to assess infiltration rates of the soils for design of an onsite stormwater infiltration system. Because the site is located within an area identified by CGS as being potentially susceptible to the occurrence of liquefaction, we performed evaluations for liquefaction potential and provided in our report results of the analyses, including susceptibility of the site to liquefaction and seismically induced settlement. Leighton’s geotechnical design recommendations were provided for construction earthwork, slab- on-grade and conventional shallow foundations, seismic design parameters in accordance with the California Building Code, lateral earth pressure parameters for retaining wall backfill, and setbacks of the stormwater infiltration system. Leighton also provided pavement design specifications for asphalt concrete and Portland cement concrete (PCC).

Additionally, Leighton performed a geotechnical review to verify that geotechnical recommendations were properly implemented into the foundation and grading plans and water quality management plan. In support of construction, we conducted geotechnical observation and testing of earthwork operations as well as materials testing and inspection, including concrete sampling, structural steel welds, and plant tag and sample for rebar and masonry units.

When asbestos containing materials, lead-based paint, and lead-contaminated items were removed from the project site, Leighton managed the air monitoring, sampling and testing services performed by Cal OSHA certified asbestos technicians and verified that removal and containment of hazardous materials were performed properly in accordance with applicable regulations.

10 SECTION 2: SCOPE OF WORK
SECTION 2: SCOPE OF WORK
The Leighton team will work closely with your staff, appropriate regulatory agencies and other stakeholders to ensure your priorities and expectations are fully realized. Through previous successful as-needed contracts, we have found the most important management tool to ensure project success is proactive communication.

Depending on the scope identified in the specific project, we will likely recommend a project kickoff meeting so we can establish a full understanding of your goals and confirm expected work product deliverables, and introduce key project participants. Project priorities including budget, scope, value engineering, and milestones for deliverables will be identified and committed to by our project team. While all projects are uniquely different, Leighton anticipates the scope of work requested by the City may include the following task items presented from design phase investigations and on through completion of construction:

Geotechnical Investigation
Our geotechnical investigations will be mobilized and managed out of our Irvine Headquarters. We will prepare a detailed proposal that will be tailored to meet each individual project’s goals. The proposal will present our proposed scope of work, the anticipated schedule, and a breakdown associated fees. Each proposal will be crafted with a focus on providing expedient and cost-effective engineering solutions.

RESEARCH AND STUDIES
A task that begins during proposal preparation, our initial Research and Studies for the project will consist of performing a review of existing available documents, geologic maps, and plans relevant to the project that will provide a useful understanding of existing site conditions and site history. In addition, we may review historical stereoscopic aerial photographs and topographic maps to determine approximate existing cut and fill conditions, pre-existing development conditions, and utility conditions that may also impact the design of the project from both a field and construction perspective.

FIELD EXPLORATION
Prior to executing our field investigation scope as generally summarized below, a member of the Leighton technical staff under the direct supervision of a California-licensed Geotechnical Engineer or Certified Engineering Geologist will visit the site ascertain equipment access and determine suitable exploration methods. Our field exploration program will typically include the following scope:
• Perform a geotechnical reconnaissance of the project site including marking out of exploration locations; observation and geologic mapping of existing slopes, utility trench cuts and boxes, access constraints and geologic observation of site geology and adjacent geology where visible • Prior to our proposed subsurface exploration, we will notify Underground Service Alert ( DigAlert) to screen the proposed exploration locations for the presence of subsurface public utilities. We will also coordinate boring locations with site facilities personnel and may have our exploration locations cleared by a private underground utility subcontractor
• Acquire any necessary permits, such as a Los Angeles County Public Health Well Permit, if needed • We will perform our subsurface evaluation program that may consist of, but is not limited to, a combination of geotechnical borings, Cone Penetrometer Test soundings (CPTs) , test pits, and/or geophysical surveys. The exploration method will be selected on a project specific basis based on our understanding of the proposed development and existing site conditions . • Perform field percolation testing to support the design of proposed stormwater infiltration devices , if any. The field percolation testing will be performed in accordance with the latest Los Angeles County guidelines.
• At the completion of our field investigation, the explorations will be backfilled in accordance with County guidelines and patched to match existing surface conditions. Drill cuttings may need to be stored temporarily on- site, in clearly labeled 55-gallon drums, pending soil characterization and disposal at an appropriate receiving facility.

LABORATORY TESTING
Leighton has three laboratories (Irvine, Temecula and San Diego) with an extensive inventory of equipment and cross-trained staff that can handle many types of samples and tests. Our ability to load-level our tests between laboratories allows us to accept large volumes of samples and be more responsive to our client’s needs when rapid turn-around times are needed.

We perform a full spectrum of geotechnical soil testing in-house, including, but not limited to:
 Moisture/Density  Direct Shear  Compaction
 Specific Gravity  Triaxial Shear  Expansion Index
 Particle Size Analyses  Consolidation/Swell  Falling/Constant Head Permeability  Atterberg Limits  Stabilometer (R-value)  Corrosivity

The following is a list of common tests for aggregate, hot mix asphalt (HMA) and Portland cement concrete (PCC) that Leighton performs in our laboratories on a regular basis.

AGGREGATE (HMA & PCC) HOT MIX ASPHALT & PORTLAND CEMENT CONCRETE  Sieve Analysis  Maximum Density - Hveem
 Specific Gravity (Coarse/Fine)  Concrete Cylinder Compression  Sand Equivalent  Flexural Strength of Concrete
 Durability  Bulk specific Gravity of Compacted HMA
 LA Rattler  Asphalt Extraction by Ignition
 Soundness (Sodium/Magnesium)  Theoretical Maximum Density/Specific Gravity  Organic Impurities  Wet Track Abrasion of Slurry Seal

The quality of our laboratory is controlled using certification programs from the City of Los Angeles Department of Building and Safety (LADBS), AASHTO Materials Reference Laboratory (AMRL), California Division of the State Architect (DSA), Caltrans (various districts), among others. The quality of our analyses is controlled using verification forms that require stand-alone, fully reviewed engineering calculation packages to support design recommendations.

REPORT AND FINDINGS
We will prepare a geotechnical design report in accordance with the 2022 California Building Code and appropriate regulatory agencies guidelines and requirements. The report will contain graphics and discussions presenting our findings, conclusions, and recommendations for the project. The report will be signed by a California-licensed Geotechnical Engineer (GE) from our firm. Generally, our report will provide the following:

Subsurface Conditions: A discussion regarding the encountered subsurface soils conditions including soil type, in-situ moisture content and density, and depth to groundwater Geologic Hazards: We will discuss potential geologic hazards at this site, including potential for surface fault rupture, ground shaking, liquefaction, lateral spreading and differential seismic settlement, and potential flood hazards at the site using available data.

Seismicity: We will provide a regional fault map showing the proximity of this site to major faults identified by the California Geological Survey within a 100-kilometer radius of the site. We will also perform a site-specific ground motion analysis to obtain site-specific seismic coefficients in accordance with ASCE 7-16 and the 2022 California Building Code (CBC).

Grading and Earthwork: We will present earthwork criteria, including recommendations for new footing subgrade preparation, recommendations for removal of unsuitable soil or fill, utility trench backfill, surface drainage, and landscaping considerations, as necessary. Recommendations for import soil engineering and compaction criteria will also be provided.

Foundations: Utilizing data collected during our exploration, we will recommend allowable vertical and lateral bearing pressures for use in designing new spread-footing foundations. We will also provide foundation design criteria including recommendations for minimum size, embedment depth, allowable vertical and lateral capacities, and expected total and differential settlements. In addition, foundation recommendations for light poles footings, fence post footings, and other free-standing canopy structures will be provided.

Lateral Earth Pressures: Recommended lateral earth pressures for active, at-rest and passive conditions, and soil friction will be provided for use in retaining wall design.

Slabs-On-Grade: We will present concrete slab-on-grade design criteria, including recommendations for subgrade preparation, moisture vapor mitigation and if necessary, non-expansive fill.

Asphalt Concrete and Portland Cement Concrete Pavements: We will provide recommendations for AC and PCC pavement sections based on assumed traffic indices. We will also provide recommendations for permeable and precast pavers.

Temporary Excavations: Utilizing the data collected during our exploration, we will present temporary excavation guidelines (construction site safety is the responsibility of the contractor).

POST-REPORT SUBMITTAL SERVICES
A/E Team Coordination and Review: We will provide geotechnical support for the design team during preparation of the project drawings and specifications. We will review the project drawings and specifications for compliance with our geotechnical recommendations.

General Contractor Bidding Phase Services: Respond to bid questions including requests for information (RFIs) as they relate to geotechnical items; and attend project meetings and participate in conference calls with the design team.

SCHEDULE
Upon receipt of a written notice-to-proceed Leighton is prepared to immediately commence project planning and scheduling. California law requires that Underground Service Alert (USA) be provided at least two working days advanced notice to locate registered public utilities at the project site before exploration can begin.

Depending on potential site access constraints, weather and exploration equipment availability, field exploration may begin five to ten working days after receipt of notice to proceed. Depending on project specific scope details, our field exploration can be completed in one or more days. In general, geotechnical laboratory testing will require approximately two weeks to complete after the conclusion of field exploration. Geotechnical analyses and report preparation will then require an additional 2 weeks after completion of lab testing. We anticipate we can provide our geotechnical report within approximately 4 weeks after field exploration. We can provide preliminary results upon request in a technical memorandum as site-specific information becomes available.

Geotechnical Observation and Testing Services
The purpose of our geotechnical field observation and testing during construction will be to document that the work performed by the contractor is in compliance with the applicable plans and specifications and in accordance with applicable sections of the 2022 California Building Code. Our geologist and/or soils technician will inspect all excavations to verify the conditions anticipated in the approved project geotechnical report have been encountered and to provide corrective recommendations as deemed appropriate. It is not our intent to provide supervision or direction of the contractor or the contractor’s subcontractors.

We will dispatch to the project site qualified engineering technicians to perform field observation and testing of earthwork operations. Our field testing and observation activities will be performed on an “on-call” basis upon request by the project superintendent at the appropriate times during construction. However, we do require that our field representative be present continuously during the earthwork associated with remedial grading and/or preparation of building pads so that we may properly document the depth overexcavation and geotechnical characteristics of the compaction of the fill.

Based on our understanding of the proposed projects, the anticipated tasks for our scope of services will consist of the following field, laboratory and office work, generally presented in chronological order:
 Pre-Construction Plan Review: We will perform technical review of the grading plans and foundation plans for the project by our Geotechnical Engineer (GE) and Certified Engineering Geologist (CEG). We will prepare a letter documenting our review of each plan set, including signature and stamp, as needed. In addition, we will provide response to contractor’s requests for information (RFI’s) as requested.  Pre-Construction Meeting: Our project manager and field operations manager will attend a pre- construction meeting with representatives of the contractors/sub-contractors and construction management team to establish any site access restrictions, points of contact, protocol for scheduling our services, and distribution list for DFRs and test results.
 Field Observation and Testing: We will provide a soil technician for periodic and continuous geotechnical observation and testing during site preparation, overexcavation, and fill placement during earthwork construction, and general site grading. The frequency of observation and testing required will be established by the governing agency and the project inspector at the pre- construction meeting. In- situ density testing will be performed using a nuclear moisture/density gauge (ASTM D 6938).  Geotechnical Laboratory Testing: Geotechnical (soil) testing may include, but not li mited to, modified Proctor (ASTM D 1557) maximum dry density and optimum moisture content compaction curves, gradation, sand equivalent, corrosivity, expansion and R-Value.  On-call Engineering Support: We will respond to requests for information (RFIs), attend meetings, and support value engineering efforts on an as-needed basis.  Project Management: This scope of work will consist of reviewing DFRs and laboratory test results and preparing these reports for distribution. Geotechnical concerns encountered in the field and noted in the daily reports, and any material tested and found to not conform to project specifications, will be brought to the attention of your designated representative (s). Supervision, quality control and project management will be provided by our Geotechnical Engineer.
 Compacted Fill Report: We will prepare a compacted fill report summarizing our test results and observations made during construction.

Materials Testing and Special Inspection Services
Our scope of services for the proposed projects will consist of materials testing and special inspection during construction. Our understanding of the proposed projects will be based on the project plan sets and specifications provided by the City. The anticipated tasks for our scope of services will consist of the following field, laboratory and office work, generally presented in chronological order.  Reinforcing Steel Source Sampling: We will pick up reinforcing steel samples and “tag” source materials for site delivery identification. Sampled reinforcing steel will be tested in accordance with ASTM A370, and A615 or A706.

Scheduling and Dispatching
Leighton is prepared to begin our work immediately upon receipt of your written authorization to proceed. We would appreciate at least three working days advance notice for scheduling our field personnel on the first day you require our services. Work thereafter may be scheduled with a full (24 hours) one working day advance notice. We will rely on your field representative to contact us to schedule all fieldwork, and to help us avoid unproductive site visits. Contact on the weekends and holidays are not addressed until the first following working day, without prior arrangement. We request that you “partner- with-us” to manage our budget, by avoiding unnecessary trips to the site. We will work with your field representative to reduce standby time and/or unnecessary trips to the site.

OTHER CONSULTING SERVICES
In addition to the core geotechnical services described above that are expected to be provided as part of the on-call contract, we understand that other consulting services associated with geotechnical and geologic consulting services may be required. These services might include:

Landslide Repair Design: For more than 60 years, Leighton has been providing the integrated geotechnical engineering and engineering geology services required for landslide repairs. In addition to our experience with site characterization and mitigation design concepts, our Geotechnical Engineers (GEs) prepare assessment and mitigation reports and prepare repair grading plans and specifications, including remedial earthwork, soil nail and/or earth anchor (“tie-back”) design, conventional shoring to reestablish roadways, safe utility corridors or to support existing structures with underpinning. For more complex shoring designs, we will consult with an experienced Structural Engineer (SE) who has experience focused on shoring.

Remedial Grading Plan Preparation: Although geotechnical engineers provide essential input for all grading plans, such plans are more routinely prepared by general-practice Civil Engineering firms. On occasion, however, grading consists only of geotechnical remediation earthwork, such as for landslide stabilization. In these cases, Leighton has and will assume the lead on designing slope stabilization buttresses and/or other remedial earthwork and will prepare final design stabilization grading plans in house, possibly with assistance from a civil engineering subconsultant for Professional Land Surveying (PLS) services and minor general civil engineering support to establish property boundaries and easements.

Peer Review: Leighton will provide Third Party review services to assist the City in the evaluation of geotechnical reports prepared by others. We do this routinely for our other clients. Based upon our review, we will provide written comments and recommendations to the City for additional analysis, if needed. In addition, we will attend meetings with the technical team to discuss project priorities and progress. For Third Party reviews to add value, a mentorship attitude, rather than competitive attitude, is required. We only provide comments that are necessary to ensure compliance and result in enhanced public safety, avoiding any real or perceived bias against other involved professionals.

Value Engineering (VE): Leighton will evaluate several alternatives for geotechnical design to ensure appropriate cost-effective measures are implemented when appropriate.

Drafting Services: Leighton has full in-house drafting capabilities utilizing AutoCAD Civil 3D, MicroStation, and analytical/visualization tools such as ArcGIS, Modflow, Rockworks, and gINT software. We possess the full array of information technology and field equipment necessary to successfully support large-scale, geospatial data-intensive projects such large pipeline in complex geologic areas.

Additionally, we can use computer graphics to visually convey the results of our studies. Illustrations and report graphics are developed utilizing a variety of data imaging and geospatial analysis software. Boundaries, delineations, visualizations and proposed land uses are compiled and viewed in a GIS platform, using ArcGIS,

FEE SCHEDULE

TERMS AND CONDITIONS
z Proposal Expiration: Proposals are valid for at least 30 days, subject to change after 30 days; unless
otherwise stated in an attached proposal.
z Prevailing Wages: Our fees for prevailing wage work
are based upon California prevailing wage laws and
wage determinations. Unless specifically indicated in
our proposal, costs for apprentice are not included. If we are required to have an apprentice on your project,
additional fees will be charged. Prevailing wage rates
will increase by $8 on July 1st of each year.
z Overtime: Standard overtime rate is per California
Labor Law and is billed at 1.5 or 2 times their hourly
billing rate. Overtime rate for non-exempt field
personnel working on a Leighton observed holiday
is billed at 2 times their hourly billing rate. Overtime rate for Prevailing wage work is per the California
Department of Industrial Relations (DIR) determination
and is multiplied at 1.5 to 2 times their hourly billing rate for overtime and double-time, respectively.
z Expert Witness Time: Expert witness deposition and
testimony will be charged at 2 times hourly rates listed on the previous pages, with a minimum charge of four
hours per day.
z Minimum Field Hourly Charges: For Field
Technicians, Special Inspectors or any on-site (field)
materials testing services:
4 hours: 4-hour minimum charge up to the first
four hours of work.
8 hours: 8-hour minimum charge for over four
hours of work, up to eight hours.

Project time accrued includes portal to portal
travel time.
z Insurance & Limitation of Liability: These rates are predicated on standard insurance coverage and a limit
of Leighton’s liability equal to our total fees for a given project.
z Outside Direct Costs: Heavy equipment,
subcontractor fees and expenses, project-specific
permits and/or licenses, project-specific supplemental
insurance, travel, subsistence, project-specific
parking charges, shipping, reproduction, and other
reimbursable expenses will be invoiced at cost plus
20%, unless billed directly to and paid by client.
z Invoicing: Invoices are rendered monthly, payable
upon receipt in United States dollars. A service
charge of 1½-percent per month will be charged for
late payment.
z Client Disclosures: Client agrees to provide all
information in Client’s possession about actual or
possible presence of buried utilities and hazardous
materials on the project site, prior to fieldwork, and
agrees to reimburse Leighton for all costs related to
unanticipated discovery of utilities and/or hazardous
materials. Client is also responsible for providing safe and legal access to the project site for all Leighton
field personnel.
z Earth Material Samples: Quoted testing unit
rates are for soil and/or rock (earth) samples free of
hazardous materials. Additional costs will accrue
beyond these standard testing unit rates for handling,
testing and/or disposing of soil and/or rock containing hazardous materials. Hazardous materials will be
returned to the site or the site owner’s designated
representative at additional cost not included in
listed unit rates. Standard turn-around time for
geotechnical-laboratory test results is 10 working
days. Samples will be stored for 2 months following
completion of assigned tests, after which they will be
discarded. Prior documented notification is required
if samples need to be stored for a longer time. A
monthly storage fee of $15 per bag and $6 per sleeve
or tube will be applied. Quoted unit rates are only for earth materials sampled in California. There may be
additional cost for handling imported samples.
z Construction Material Samples: After all
designated breaks for a given sample set meet
specified compressive at design age or other client-
designated strength, all “hold” cylinders or specimens
will be automatically disposed of, unless specified in
writing prior to the 28-day break. Unless specifically requested otherwise, all other construction materials
will be disposed of after completion of testing and
reporting.
