B PROJECT APPROACH AND PROPOSED SCOPE
B.1 Project Understanding
B.1.1 ObjecƟves
The City of Diamond Bar is implemenƟng a three-year pavement rehabilitaƟon and ADA improvement program as
part of its 2025 Pavement Management Program (PMP) Update. The program’s purpose is to preserve the City’s
pavement network in a cost-efficient way while addressing localized deficiencies in ADA access and mulƟmodal
conƟnuity.
The program combines prevenƟve maintenance, localized
rehabilitaƟon, and targeted reconstrucƟon to extend pavement
life and maintain a citywide PCI in the “Good” range/ The project
also includes ADA curb ramp design in Areas 1, 6, and 7, where
many ramps were installed prior to the 2010 ADA Standards and
now require geometric correcƟon or full replacement.
We understand that the Project is compartmentalized into 10
individual projects. See Figure 5 Project Map on page 15. The 10
projects are understood to be defined as follows:
Project 1: ADA Curb Ramp Improvement Project (Area 6)
(approximately 1.08 square miles)
Project 2: Arterial Street RehabilitaƟon:
• Brea Canyon Rd: Diamond Bar Blvd. to Pathfinder Rd.
(approximately 6,388 lineal feet (LF))
• Brea Canyon Rd: Pathfinder Rd. to Washington Ave.
(approximately 5,800 LF)
• Diamond Bar Blvd: SR-60 Off-Ramp to City Limit
(approximately 7,235 LF) (Figure 1)
•
Project 3: ADA Curb Ramp Improvement Project (Area 7)
(approximately 3.13 square miles)
Project 4: ResidenƟal & Collector Streets RehabilitaƟon (Area 5)
(approximately 0.91 square miles)
Project 5: Arterial Street RehabilitaƟon:
• Pathfinder Rd: Diamond Bar Blvd. to City Limits.
(approximately 7,920 LF)
Project 6: ADA Curb Ramp Improvement Project (Area 1)
(approximately 1.76 square miles)
Project 7: ResidenƟal & Collector Streets RehabilitaƟon (Area 6)
(approximately 1.08 square miles)

B. Project Approach and Proposed Scope | 4
• Grand Ave: Diamond Bar Blvd. to Lavender Dr. (approximately 2,777 LF)
• Diamond Bar Blvd: Clear Creek Canyon Dr. to Golden Springs Dr. (approximately 5,800 LF)
Project 9: Arterial Street RehabilitaƟon:
• Temple Ave/Avenida Rancheros: Diamond Bar Blvd. to City Limits (approximately 2,122 LF)
Project 10: Arterial Street RehabilitaƟon:
• Diamond Bar Blvd.: Pathfinder Rd. to South of Fallow Field Dr. (approximately 3,500 LF)
• Brea Canyon Road: Diamond Bar Blvd. to city limits. (approximately 3,333 LF)
B.1.2 Key Technical Drivers
1. Pavement Treatment VerificaƟon
The City’s PMP idenƟfies treatments such as slurry seals, cape seal, thin overlay, and full depth
reconstrucƟon. These recommendaƟons must be field verified through coring, distress mapping, and
cross-secƟon evaluaƟon to confirm structural adequacy and idenƟfy interlayers or base failures. This
ensures each street segment receives the appropriate treatment for its actual field condiƟon, not just its
modeled PCI.
2. Complete Streets and Bikeway IntegraƟon
Along arterials such as Diamond Bar Boulevard and Grand Avenue, the City has an adopted Complete
Streets Policy that requires evaluaƟon of bicycle faciliƟes. The corridors have constrained rights-of-way.
The design must evaluate feasible cross-secƟons for bike lanes while maintaining drainage funcƟon and
parking access where appropriate.
3. ADA Compliance and Curb Ramp Design
The program will reconstruct curb ramps to meet current ADA standards. Field verificaƟon is essenƟal to
confirm ramp counts, exisƟng grades, and feasibility of achieving compliant slopes within available right-
of-way.
4. UƟlity CoordinaƟon and Subsurface Risk Management
Arterial corridors typically carry mulƟple uƟliƟes. Early coordinaƟon with uƟlity owners will be criƟcal to
prevent design conflicts at curb ramps and pavement conform limits.
5. Phased ImplementaƟon and Program Consistency
The City intends to implement a three-year program and may reprioriƟze projects based on funding and
operaƟonal needs. Maintaining consistency in sheet layout, bid items, and specificaƟons across program
years will allow the City to combine or defer projects efficiently. Project 7 is expected to be designed for
future construcƟon, requiring “shelf-ready” plans that integrate seamlessly with later bid packages.

B.1.4 Understanding of City PrioriƟes
The City’s Key objecƟves can be summarized as follows:
Deliver bid-ready PS&E that minimizes construcƟon risk and aligns with the City’s pavement management
strategy
Ensure ADA compliance and measurable accessibility improvements
Evaluate and integrate Complete Streets principles for mulƟmodal compaƟbility within exisƟng curb-to-
curb widths
Maintain program-level consistency in design standards, cost esƟmaƟng and document formaƫng
Provide clear, responsive coordinaƟon with City staff, uƟliƟes and stakeholders throughout design
B.2 ImplementaƟon Plan
B.2.1 Task 1 - Project CoordinaƟon
Following NTP, AYCE will conduct a kickoff meeƟng with the City staff to confirm project objecƟves, prioriƟes, and
communicaƟon protocols. We will establish a Project Management Plan at project iniƟaƟon defining
communicaƟon protocols, QA/QC procedures, and the project schedule. We will host monthly progress meeƟngs
to track deliverables and align prioriƟes. All decisions made in these meeƟngs will be documented.
AddiƟonally, we will establish a project risk register with miƟgaƟon strategies for potenƟal schedule or cost impacts
such as uƟlity conflicts or field access delays.
B.2.2 Task 2 - Field Review, Survey, & UƟlity InvesƟgaƟon
Field acƟviƟes will begin with a review of the City’s 2025 PMP data. Ayce will verify pavement condiƟon through
visual inspecƟon, limited coring, and distress mapping to confirm the validity of exisƟng PCI raƟng and treatment
categories. RepresentaƟve geotechnical borings will be performed to confirm pavement thickness, base type, and
subgrade support.
Topographical survey data will be collected using total staƟon and GPS methods. LiDAR may be employed where
efficient or safety warrants. Survey will capture flowlines, cross-guƩer elevaƟons, and curb ramp grades needed to
evaluate drainage and ADA compliance.
UƟlity research will begin early. AYCE will compile an uƟlity base map idenƟfying water, sewer, storm drain, gas,
electric, and communicaƟon faciliƟes. SelecƟve potholing will confirm verƟcal and horizontal clearances at high-risk
crossings.
B.2.3 Task 3 - Preliminary Engineering and Geotechnical EvaluaƟon
Preliminary Engineering will build directly upon verified field data. We will assess roadway cross slopes, drainage
paƩerns, and exisƟng curb and guƩer condiƟons to define the design limits. The geotechnical results will inform us
of the pavement structural design. Each roadway segment will receive a preliminary design memorandum
summarizing recommended treatment type, secƟon thickness, and constructability consideraƟons. We will
coordinate closely with the City to ensure consistency with the PMP.
FY 25/26 CIVIL ENGINEERING DESIGN SERVICES
City Project No. SI261
B. Project Approach and Proposed Scope | 6
Preliminary engineering will also include idenƟficaƟon of bikeway and striping improvements consistent with the
City’s Complete Streets policy and Caltrans design standards.
For ADA areas 1,6, and 7, the team will prepare conceptual ramp layouts based on field data for 8 ramps per area.
Addendum 1 idenƟfies use of Community Development Block Grant (CDBG) funding for ADA curb-ramp work. AYCE
will coordinate early with City staff to determine documentaƟon requirements for prevailing wage, environmental
review as applicable, and federal reporƟng.
B.2.4 Task 4 – Project Planning
AYCE will prepare a Project Planning document idenƟfying the proposed projects, work limits, and cost esƟmates
for each group idenƟfied in the City’s program. AYCE will:
Confirm the limits and scope of each project area
Coordinate with City to finalize construcƟon limits, ADA curb ramp locaƟons, and project prioriƟes
Develop project planning maps and spreadsheets summarizing limits and scope of work
Provide GIS-based exhibits.
B.2.5 Task 5 - Plans, SpecificaƟons, and EsƟmate (PS&E) PreparaƟon
AYCE will prepare complete PS&E packages for the arterial, residenƟal/collector, and ADA ramp projects in
accordance with City, Caltrans and APWA standards.
Each PS&E milestone (30%, 60%, 90%, and 100%) will undergo internal QA/QC review prior to submiƩal. City
review comments will be logged and resolved at each stage.
Plans will include:
Pavement rehabilitaƟon limits, cross secƟons, and structural secƟons
Typical details for slurry seal, overlay, and full-depth reconstrucƟon
Revised cross-guƩer or drainage profiles where flow issues are documented
Bikeway and striping layouts
ADA curb ramp sheets
All drawings will be prepared in AutoCAD.
B.2.6 Task 6 - Bid Support
Our team will assist the City during the bidding process by responding to contractor inquiries, preparing addenda,
and supporƟng evaluaƟon of bids. Once construcƟon is underway, we will provide submiƩal reviews, responses to
RFIs, field visits, and preparaƟon of record drawings. Targeted oversight will be provided for criƟcal features such as
ADA ramps, lighƟng systems, and landscaping to ensure design intent is achieved.
For the CDBG-funded ADA ramp projects, AYCE will also support City staff in addressing contractor inquiries related
to federal wage rates and reporƟng requirements to ensure complete and compliant bid documentaƟon.
B.2.7 Task 7 – ConstrucƟon Support & As-builts
During construcƟon, AYCE will provide design support services to respond to RFIs, review submiƩals, and aƩend
site meeƟngs at criƟcal milestones. We will visit the project sites to observe paving and ADA ramp construcƟon for
compliance.
All field changes and contractor markups will be captured and transferred into Final As-built Drawings. A Final
project closeout report will summarize quanƟƟes, design adjustments, and lessons learned for integraƟon into the
next PMP update.

B. Project Approach and Proposed Scope | 7
B.3 Risk Based ConstrucƟon Method EvaluaƟon
AYCE will perform a risk-based construcƟon method evaluaƟon to select the appropriate construcƟon methods for
the project. We will evaluate potenƟal treatment methods based on:
Cost efficiency
Constructability
PotenƟal construcƟon risks
The evaluaƟon will incorporate pavement condiƟon data, site constraints, and anƟcipated field condiƟons to
determine the most suitable treatment for each roadway segment. Common risks such as subgrade failure, shallow
uƟliƟes, and access limitaƟons to commercial and residenƟal driveways will be assessed for likelihood and impact
along with corresponding miƟgaƟon strategies.
For ADA compliance, the project will include full curb ramp replacement rather than retrofit, ensuring all ramps
meet current accessibility standards. Common ramp reconstrucƟon risks such as drainage conflicts, limited right-of-
way, and temporary pedestrian access will be addressed through early field verificaƟon, coordinaƟon with uƟlity
owners, and detailed construcƟon phasing.
The results of our evaluaƟon will be summarized in a risk matrix and used to guide the selecƟon of construcƟon
method. The purpose of this evaluaƟon is to support the City in selecƟng appropriate construcƟon methods for
street surface treatment and rehabilitaƟon and ADA-compliant curb ramp upgrades.
A risk-based approach allows the City to evaluate each method not only on cost and performance, but also on
constructability, schedule, environmental exposure, and implementaƟon risk, ensuring opƟmal long-term value and
minimal disrupƟon to the public.
B.3.1 Pavement Treatment OpƟons Considered
Category Methods Typical
ApplicaƟon
Expected Service

(FDR)
PCI < 60 10–20 years
Each treatment type is evaluated based on pavement condiƟon, exisƟng structure, drainage, uƟlity locaƟons, and
anƟcipated traffic loads.
B.3.2 Curb Ramp Replacement ConsideraƟons
The following design and construcƟon factors are criƟcal:
Field verificaƟon of grades to ensure feasible ramp geometry and compliant slopes.
PotenƟal drainage impacts near ramp landings and curb inlets.
CoordinaƟon with pavement limits, ensuring concrete ramps are built before final surface treatment.
Temporary pedestrian accessibility maintained through detour routes or temporary ramps.
FY 25/26 CIVIL ENGINEERING DESIGN SERVICES
City Project No. SI261
B. Project Approach and Proposed Scope | 8
Typical construcƟon risks for curb ramps include shallow uƟliƟes, conflicts with driveways, and limited right-of-way.
MiƟgaƟon measures include early potholing, surveying, and including dedicated bid items for sidewalk and curb
ramp replacement.
B.3.3 ComparaƟve EvaluaƟon of Pavement Methods
A comparaƟve evaluaƟon of pavement rehabilitaƟon methods will be conducted using a weighted scoring matrix to
assess various alternaƟves—such as slurry seal, micro-surfacing, cape seal, thin overlay, mill and overlay, and full-
depth reclamaƟon—against key criteria including cost efficiency, schedule and curing Ɵme, constructability, risk
exposure, and longevity. Each criterion will be assigned a weighƟng factor to reflect its relaƟve importance, with
greater emphasis placed on cost efficiency and schedule performance. The results will idenƟfy which pavement
methods provide the most cost-effecƟve and low-risk treatments for pavements in good to fair condiƟon, as well as
those best suited for more deteriorated pavement segments. Surface treatments like micro-surfacing and cape seal
are anƟcipated to offer the best balance between cost, performance, and minimal construcƟon risk, while thin
overlays will likely be appropriate for moderate deterioraƟon requiring limited structural improvement. More
intensive treatments, such as mill and overlay or full-depth reclamaƟon, will be reserved for severely distressed
pavements or locaƟons with underlying base or drainage failures. This evaluaƟon methodology will help guide
data-driven selecƟon of pavement strategies that opƟmize performance, cost, and constructability.
B.3.4 Risk MiƟgaƟon Strategy
To minimize overall project risk:
• Perform field coring and deflecƟon tesƟng prior to selecƟng the final pavement treatment.
• Construct curb ramps before surface treatments to avoid damaging new concrete during paving
operaƟons.
• Include unit bid alternaƟves (e.g., both micro-surfacing and slurry seal) for flexibility during
construcƟon.
• Specify temporary pedestrian access requirements during curb ramp reconstrucƟon.
• Include weather and curing condiƟon limitaƟons in the project specificaƟons.
• Coordinate with uƟliƟes early to prevent construcƟon delays.
Based on the risk-weighted evaluaƟon and depending on pavement life design year, our team will provide a
recommendaƟon for each project:
High PCI (>70): Apply slurry seal or micro-surfacing.
Moderate PCI (60–70): Apply cape seal or thin overlay.
Low PCI (<60): Apply mill & overlay or full-depth reclamaƟon.
Curb ramps: Replace all non-compliant ramps with full reconstrucƟon to current ADA standards,
coordinated with pavement rehabilitaƟon phasing.
B.3.5 Deliverable
A Risk-Based ConstrucƟon Method EvaluaƟon Report or secƟon in the design memo should summarize:
Pavement condiƟon and treatment
selecƟon logic,
Risk register and scoring matrix,
Curb ramp replacement approach and
sequencing, and
Recommended miƟgaƟon strategies.

B.4 Project Approach
B.4.1 Pavement RehabilitaƟon Approaches
The purpose of DYA’s services will be to perform a field exploraƟon and laboratory tesƟng program and prepare a
Geotechnical Report in support of the Project. DYA’s scope of services for site exploraƟons will consist of the
following:
• Preparing a Geotechnical ExploraƟon Workplan
and obtaining a City of Diamond Bar No fee
Encroachment Permit.
• For each project, we assume an approximate
spacing of 500 lineal feet for each core and an
approximate spacing of 1,000 lineal feet for each
boring. We esƟmate a total of roughly 116 to
135 corings as well as advancing 10-foot-deep
borings in 61 to 71 of these coring locaƟons.
• For Project 2, perform 36 to 43 pavement cores
and advance 18 to 23 of the pavement cores to
geotechnical borings to a depth of 10 feet.
• For Project 4, perform 12 to 16 pavement cores
and advance 6 to 8 of the pavement cores to
geotechnical borings to a depth of 10 feet.
• For Project 7, perform 12 to 16 pavement
cores and advance 6 to 8 of the pavement
cores to geotechnical borings to a depth of 10
feet.
• For Project 5, perform 12 to 16 pavement
cores and advance 6 to 8 of the pavement
cores to geotechnical borings to a depth of 10
feet.
• For Project 7, perform 12 to 16 pavement
cores and advance 6 to 8 of the pavement
cores to geotechnical borings to a depth of 10
feet.
• For Project 8, perform 23 pavement cores and
advance 11 pavement cores to geotechnical
borings to a depth of 10 feet.
• For Project 9, perform 5 pavement cores and
advance 3 pavement cores to geotechnical
borings to a depth of 10 feet.
• For Project 10, perform 16 pavement cores
and advance 10 pavement cores to
geotechnical borings to a depth of 10 feet.
• TransporƟng the collected geotechnical soil
samples to the laboratory and conducƟng
tests following ASTM standards. Soil tesƟng
will tentaƟvely consist of the following, but
not be limited to, soil index properƟes (minus
#200 sieve, grain size distribuƟon, AƩerberg
limits), moisture content and dry density,
expansion index, compacƟon, R-value, and
corrosion suite (pH, sulfates, chlorides and
electrical resisƟvity).
• Providing an inventory of the pavement
secƟons at each of the approximately 116 to
135 coring locaƟons.
• Preparing soil boring logs containing
informaƟon such as, but not limited to, soil
type classificaƟons per the United Soil
ClassificaƟon System (USCS), soil descripƟons,
laboratory test results of selected soil
samples, and standard penetraƟon tesƟng
(SPT) blows per foot for geotechnical
engineering design.
DYA’s scope of services for reporƟng will consist of the following:
• Results of the geotechnical/geological data
review that may supplement the field
exploraƟon performed.
• PresenƟng maps of the field exploraƟon
locaƟons and results of the field exploraƟon
and laboratory tesƟng.
• Summarizing the subsurface condiƟons
based on the field exploraƟon and
presenƟng idealized soil profiles of each of
the individual Project sites.
• Summarizing the pavement secƟons
encountered at each of the approximately
FY 25/26 CIVIL ENGINEERING DESIGN SERVICES
City Project No. SI261
B. Project Approach and Proposed Scope | 10
116 to 135 coring locaƟons. • Groundwater
depth/elevaƟon if encountered.
• Results of engineering analyses for the
design of, slabs-on-grade, concrete flatwork,
and pavements (flexible and rigid).
• Earthwork and construcƟon consideraƟons.
• Suitability of site excavated material for
use as fill or backfill material
• RecommendaƟons for uƟlity trench backfill.
• Corrosion potenƟal of onsite material to
concrete
It is our understanding that the City will not require full restoraƟon (i.e., hot patching) of pavements aŌer field
acƟviƟes have been concluded. DYA’s field exploraƟon will consist of a 6 to 10-inch diameter borehole cored into
the pavement. We understand that this Project will not consist of rehabilitaƟng or replacing pavements at each of
the 116 to 135 proposed coring/boring locaƟons. We understand that the City will permit DYA to successfully
submit a no-fee encroachment permit, and close appropriate lanes for the necessary field work using only the
Manual on Uniform Traffic Control Devices (MUTCD) and that signed and stamped traffic control plans will not be
required. Given that signed and stamped traffic control plans for the roughly 8.5 miles and 2 square miles of total
project alignment including approximately 116 to 135 field exploraƟon locaƟons would present a significant
addiƟonal cost to the Project.
B.4.1.1 Arterial Street RehabilitaƟon Projects Pavement, bikeway and Striping Improvements*
Arterial Corridors such as Brea Canyon Road, Diamond Bar Boulevard, Pathfinder Road, Grand Avenue, and Temple
Avenue/Avenida Rancheros carry high volumes and truck percentages, requiring a robust rehabilitaƟon approach.
Our team will begin with targeted field verificaƟon to confirm the structural adequacy of exisƟng pavement layers.
Design will be based on the City’s 2025 PMP treatment matrix, refined by field data and geotechnical results.
Where PCI is in the mid-60s, we will prioriƟze think overlays or cape seals to extend life at lower cost and where PCI
drops into the 40s, we will design thicker RHMA overlays with base repair.
We will evaluate bikeway feasibility along each corridor
in accordance with the City’s Complete Streets Policy
and Caltrans Standards. A key challenge when
evaluaƟng the feasibility of bike lanes along the
corridors are any exisƟng parking. For example, there
are exisƟng streetside parking along Pathfinder by
Diamond Bar High School. The parking lanes would
need to be removed to install bike lanes along these
corridors. AddiƟonally, Many arterials already have
exisƟng bike lanes in place. For these locaƟons, we will
evaluate adding addiƟonal buffers and high visibility
markings to improve the safety of cyclists using those
lanes.
B.4.1.2 ResidenƟal and Collector Street RehabilitaƟon (Areas 5-7) Pavement and Cross-guƩers*
For the residenƟal and collector networks, our objecƟve is to extend pavement life using low-cost prevenƟve
treatments. We will confirm field PCI values and distress types idenƟfied in the PMP then group streets by

B.4.2 ADA Curb Ramp Improvement Areas (1,6, and 7)
The Addendum idenƟfies that the project will include approximately eight ramps per project area for Areas 1, 6,
and 7. These curb ramps are to be funded through the CDBG program.
All ramp designs must comply with current ADA standards and follow Caltrans Design InformaƟon BulleƟn (DIB) 82-
06 guidelines. Our approach will be to minimize footprint and impacts to adjacent faciliƟes such as uƟliƟes, traffic
signal poles, pedestrian push buƩons, and right-of-way.
We will perform detailed topographic surveys of each locaƟon to capture flowline elevaƟons, cross-slopes, and
obstrucƟons. CoordinaƟon with uƟlity owners will occur early to address vaults or pull boxes within ramp
footprints. We will maintain a running compliance log for QA/QC and construcƟon tracking.
Each ramp will be evaluated for:
Feasibility for achieving full ADA compliance
Impacts to adjoining infrastructure such as driveways
From our experience on the recently completed Caltrans District 7, SR-210 ADA Curb Ramps Design Build Project,
AYCE came up with a RULES framework that demonstrated a deep understanding of the ADA – its core principles,
its requirements, and its implicaƟons across various design elements. Using Design Caltrans Design BulleƟn
InformaƟon (DIB) 82-06 as the foundaƟon, our framework ensures thorough compliance with all requirements.
Slope values are from Caltrans Standard Plan A88A so that faciliƟes meet requirements from DIB 82-06 aŌer
construcƟon tolerance. The figure below outlines AYCE’s RULES framework.
The RULES framework serves as a design checklist and overall guideline for our designs, confirming and
guaranteeing compliance.
B.4.3 Project Management and Design CoordinaƟon
AYCE’s project management approach prioriƟzes clear communicaƟon with City staff, proacƟve schedule control,

Work Approach.
B.4.3.3 QA/QC Process
AYCE consistently delivers quality projects for clients through our proven Quality Management System (QMS). Our
QMS focuses on policies and procedures that ensure that project deliverables are checked, complete, accurate,
error-free, and in conformance with the defined standards and criteria. Key elements of our quality plan include:
ProducƟon quality control reviews
Over-the-shoulder reviews
Periodic and milestone reviews
Interdisciplinary reviews
Constructability reviews
All deliverables will undergo QA/QC review prior to submiƩal. Each designer and reviewer are responsible for
resolving and documenƟng comments and responses. Our QA/QC process includes:
Independent review by senior staff
Comment-response tracking on all plan sets and technical deliverables
City feedback integrated between each PS&E phase
AYCE requires that all team members, including subconsultants, parƟcipate in a quality control training session
prior to working on the project. The training highlights everything pertaining to the QA/QC process and procedures,
deliverables, reporƟng, sample QC plans, checklists, documentaƟon and file structure.
We will iniƟate a program of surveillance and audits prior to each deliverable to verify that the team has effecƟvely
developed, documented and implemented all applicable elements of the QMS in accordance with the specified
requirements. This audit informaƟon will be provided to the City.
AYCE requires all subconsultants to adhere to its quality control processes. AYCE will be responsible for ensuring the
quality of all deliverables provided to the City.
B.4.3.4 Risk Management
At the start of the project, AYCE will develop a risk register idenƟfying potenƟal risks that could have an impact on
the project. Appropriate miƟgaƟon measures will be developed to address these risks to minimize their impacts.
AddiƟonally, a risk management log will be created and shared with the City for review. We will discuss each
idenƟfied risk and eliminate their probability and consequences. Based on the overall assessment, we will
determine appropriate miƟgaƟon measures to minimize and track these risks as the project progresses.
B.5 Stakeholder IdenƟficaƟon and Engagement
EffecƟve stakeholder coordinaƟon is central to successful project delivery. Our approach emphasizes early
idenƟficaƟon, proacƟve communicaƟon, and clear documentaƟon of all engagement acƟviƟes.

City Project No. SI261
B. Project Approach and Proposed Scope | 13
We will coordinate closely with the City, Caltrans, uƟlity agencies, and affected residents, businesses, and
insƟtuƟons along project corridors. Key stakeholders include City departments, residents, business owners, uƟlity
agencies, and the City of Pomona for Project 9 coordinaƟon.
We can assist the City in communicaƟng with affected residents and business by preparing project-specific
materials that describe:
Design progress and schedule milestones
AnƟcipated construcƟon impacts
Planned miƟgaƟon or phasing strategies to maintain access
All stakeholder engagement acƟviƟes such as meeƟng summaries, contact logs, and acƟon items will be tracked
and summarized within the Project Management Plan.
B.6 InnovaƟon – InteracƟve Digital Twin
In addiƟon to providing design and construcƟon support services, AYCE’s InteracƟve Digital Twinning studio
transforms tradiƟonal engineering plans into 3D Building InformaƟon Modeling (BIM) models and InteracƟve
Digital Twins. These are virtual models powered by the 3D modelling soŌware that removes the technical barrier
needed to understand engineering plans, which allows anyone to visualize, understand, and interact with the
project design. This collaboraƟve tool offers significant advantages to design and construcƟon, such as:
1. Enhanced Constructability Reviews: Digital Twinning creates virtual walk-throughs and detects clashes, or
physical constraints between design elements, which aids the idenƟficaƟon of potenƟal constructability
issues early in the design phase.
2. Improved Engagement: Public officials, community leaders, the public, and stakeholders of all technical
backgrounds can interact with the Digital Twin and visualize how the project will look with greater ease
than tradiƟonal engineering plans. This accessibility fosters a deeper understanding of the project and
enhances community outreach efforts, which increases buy-in and leads to a smoother approval process.
3. Cost OpƟmizaƟon: Since Digital Twinning visualizes potenƟal issues early in development, miƟgaƟon
strategies can be developed earlier as well, which facilitates cost esƟmaƟon.
4. Enhanced Safety: Digital Twinning supports automated machine
guidance and digital inspecƟons during construcƟon, which enhances
safety and reduces rework.
The upper image illustrates an InteracƟve Digital Twin corresponding to the
lower image, which depicts the final civil design for the intersecƟon at Grand
Avenue and 7th Street. The digital twin offers a detailed visualizaƟon of the
project that includes intersecƟon geometry, traffic circulaƟon, pedestrian
access, and landscape features. This model serves as an effecƟve tool for
engaging stakeholders such as elected officials, City board members, and
community leaders by allowing them to explore and beƩer understand the
design. Its interacƟve capabiliƟes help reveal potenƟal design conflicts,
constructability issues, and consideraƟons related to traffic operaƟons,
pedestrian safety, and aestheƟcs.
The digital twin can also be used to detect conflicts between infrastructure elements before construcƟon begins,
evaluate constructability, simulate traffic and pedestrian movement, and incorporate stakeholder feedback on
