INTRODUCTION
After decades of neglect, to say Cuba’s infrastructure is in need of repair is an understatement. In
order to participate in the benefits of a free enterprise system, Cuba’s first step will be the
reconstruction of infrastructure up to and beyond modern standards: roadways, airports, water
distribution systems, water treatment systems, etc. This essential engineering work will facilitate
the growth of the domestic and international business that will flow into the country. This project
will assist the new Cuba in restoring a section of Avenida 51 from Calle 222 to Avenida 202 in
Havana, the “Carretera Central de Cuba.”(See Exhibit 1). Avenida 51 is a two-lane two-way
undivided roadway that runs east/west of Havana. This highway was constructed on February
1931 and is one of the country’s backbone roadways. This reconstruction project will be
comprehensive and, we hope, will set the standard for all future work.

1.0 Highway Background
Carretera Central is a highway that gives east/west access through the island of Cuba (see Exhibit
2). The formal construction of this highway began in 1927 and it was completed in 1931.
Carretera Central is a two-way two-lane highway that runs about 1,150 km. This highway is the
link to all major cities and province capitals with the exception of Cienfuegos in Cuba. It cost the
government approximately $75,870,000.00 for 705.6 miles of construction and more than
$107,000.00 per mile in order to complete this project. During the 1950s, Carretera Central was
one of the most efficient highway system in Latin America and it became popular to many
American tourists. These tourists will bring automobiles into Cuba and the tax that was paid for
the purchase of gasoline was used to maintain this highway.
Since the 1950s, there has not been a lot of investment made towards Cuba’s transportation system
and this has caused the roads and highway system to deteriorate. A report presented in November
2007 by EFECOM, shows that about 3,000km of major roadways in Cuba are in poor conditions.
Also, the Havana Government Business Construction Group which oversaw the country’s streets
and roadways, showed that more than 75% of the paved roadway and streets in Havana, Cuba are
in inadequate conditions (Exhibit 3). The deterioration of their transportation system will affect
Cuba in future economic growth.

2.0Traffic Operations
The proposed restoration project intends to improve and repair Cuba’s transportation
infrastructure, by providing a safer highway system that will help boost Cuba’s economy and be
the building block for future roadway improvements.
2.1 Roadway Characteristics
Carretera Central (Avenida 51)
Carretera Central is a major arterial that provides east/west access all along Cuba, from La Fe,
Pinar del Rio to Baracoa, Guantanamo. Within the project vicinity, Avenida 51 will be a four-lane,
two-way undivided roadway. The roadway will provide 11-foot-wide travel lanes, ten-foot
shoulders, six-foot sidewalks, and exclusive left turn lanes on the main intersections. The posted
speed limit for this section of the roadway will be 40 mph. There will not be on-street parking
permitted on Avenida 51. The government of Cuba will have jurisdiction over Carretera Central.
Exhibit 4 shows the proposed lane configurations for the one mile restoration project of Avenida
51 in La Havana, Cuba.
Calle 222
Calle 222 is a local roadway that run north/south between Avenida 51 and Avenida 23. The
roadway is a two-lane two-way undivided roadway. The posted speed limit will be 35 mph, and
the intersection of Avenida 51 / Avenida 222 will be signalized.
Avenida 202
Avenida 202 is a local roadway that runs north/south between Avenida 25 and south of Avenida
51. The roadway north of the Avenida 202 and Avenida 51 intersection is a two-way four-lane
Carretera Central Restoration Project
Page 10
divided roadway. The northbound and southbound section of the roadway at this intersection is
separated by a fountain. South of the intersection is a two-way two-lane undivided roadway. The
posted speed limit will be 35 mph, and the intersection of Avenida 51 / Avenida 202 will be
signalized.
2.2 Roadway Capacity
The Synchro software will be used to perform intersection capacity analysis at the analyzed
intersections to ensure the intersection and the roadway will operate within the Level of Service
assigned by the province of la Havana (See Exhibit6). Synchro is a macroscopic analysis and
optimization software application that implements the Intersection Capacity Utilization method for
determining intersection capacity. Synchro also supports the Highway Capacity Manual’s
methodology for signalized / un-signalized intersections. Exhibit 5 shows the specific definitions
of Level of Service by Facility type.

Turning movement counts (TMC) during the AM and PM peak period will be collected prior to
the design of the roadway to establish the existing LOS at the intersections being analyzed. Also
24-hr segment traffic volumes will be collected within project vicinity to ensure there will not be
future delays on this roadway in the future.
The corridor capacity for Avenida 51 will be estimated using generalized vehicular capacities
from the FDOT Level of Service manual. Based on Exhibit 7 and collected segment traffic
volumes, we will be able to study the corridors within Avenida 51 and establish if they will be
able to operate within the level of service standard established by the province.

2.3 Intersection Analysis
Drivers and pedestrian safety is one of the main concerns for the design of this roadway. In order
to fulfill this, the size and position of the signs at the intersections should follow the recommended
dimensions used by the Department of Transportation. This will help drivers with declining vision
and slower reaction time drive with more control on the road, and it will help prevent high rate of
crashes and any fatalities that can occur at this roadway. Exhibit 8 shows the recommended size
for warning signs.

The incorporation of traffic signals at the main intersections of Avenida 51 will help control the
right-of-way for the vehicles arriving at the intersections, which will help reduce any traffic delays
and accident producing conflicts to the existing and future traffic. The control mode for Avenida
51 is Signal control at major intersections and two-way stop control for the minor approaches.
Existing signalized intersections on this roadway should be left signalized, but for any additional
signalized intersection, a traffic signal warrant should be implemented to prevent any disruption of
traffic due to the addition of a signal.
The capacity of any of the approaches for these signalized intersections will be determined by
multiplying the saturation flow rate (vphg) by the proportion of the time that the signal controlling
the approach is effectively green, divided by the cycle length (sec).
Signal timing involves the determination of the best cycle length for each signalized intersection.
EACC Engineering recommends that the signal controller on this segment of the project be traffic-
actuated. This means that the traffic-actuated controllers will use vehicles presence information
Carretera Central Restoration Project
Page 15
from the detectors places at each approach to generate phase durations that will be appropriate to
accommodate the demand of each cycle and it will allow higher flow for the major approaches.
3.0 Roadway Design
3.1 Geotechnical Report
The City of Havana, Cuba has requested that EACC Engineering perform a geotechnical report on
the Avenida 51 from Avenida 202 to Calle 222. The report will consist of 3 core borings taken
using a standard penetration test (SPT) along the project. Boring locations were selected based on
structure placement and thorough soil investigation of the entire project area.
Proposed Construction:
The Avenida 51 Restoration Project (CCRP) includes improvements associated with capacity,
safety, traffic operations, and bike lanes. As part of the improvement program, 3 signalized
structures will be implemented.
Standard Penetration Test:
The SPT borings provide soil samples and standard penetration resistance values (N). Different
engineering properties of soils are determined by from the N number. The borings are
accomplished by the use of the rotary wash method and an automatic hammer. The open hole is
maintained by temporary casing and drilling fluids. Any disturbed soils are taken for additional
investigation. It should be noted that the majority of the soil type found was red limestone. Due to
the nature and vast knowledge of this material, major lab testing was not required.
Carretera Central Restoration Project
Page 16
Ground Water and Geologic Stratigraphy:
The project is located in the south west section of the city. The island is known to have many rainy
days as well as a high water table. The determination of the beginning of the limestone was the
key information sought out during the soil boring test.
Enough information will be gathered in order to design the foundation of all miscellaneous
structures. Due to the design of the mast arms, a minimum diameter of approximately 3’-0” is
sufficient. The depth of the soil will dictate the total depth of the drilled shaft. The drilled shaft is
more economical due to its small surface area as compared to a spread footing. The spread footing
alternative was analyzed and deemed too risky and costly primarily due to the need to find
extensive research on all as-built plans for the road.
3.2 Pavement Design
The following factors were taken into consideration during the design process of the pavement:
traffic, soils, weather, materials, construction, maintenance, and the environment. It is important to
extend the base course approximately 4 inches beyond the edge of the structural course in order to
avoid the failure of the pavement along the edges. The design includes several layers, each of
which was strategically selected by the engineer:
Friction course: FC-9.5 was selected for the reconstruction project due to the
current traffic density, speed limits, and economical reasons. This is a 1.0” inch
thick layer that will provide safety to the roadway by eliminating hydroplaning and
enhancing motorist control. FC-5 is considered in some areas in order to further
reduce costs.
Carretera Central Restoration Project
Page 17
Structural course: SP-12.5 was selected due to traffic loading. There is a hospital in
the area that typically experiences visits from heavy trucks carrying various
supplies.
Base course will generally not surpass 2’-0” due to a high water table and the
possible need of dewatering throughout the project. This depth is considered an
optimal design for practical, safety, and economical reasons.
3.3 Mast Arms
There are two signalized intersections throughout the project. Due to traffic and cyclist control,
EACC has been requested to determine the placement of these structures for safety, capacity, and
traffic operations reasons.
All mast arms throughout the project will be constructed in accordance with PPM Article
25.4.26.2. New and existing structures with planned additional loading will be analyzed in
accordance to Volume 3 of the Structures Manual. The design wind speed will be 150 mph. The
analysis performs checks of the following components: arm, upright, bolts, vertical plate, base
plate(s), connection plate, foundation, and fatigue.
For this project there are a total of two intersections. This will require the design of 4 mast arms
and 4 signalized light poles. The mast arms will be of similar dimensions in order to save on
design time. These structures were chosen for optimum safety and financial levels. The addition of
a luminaires will be further analyzed depending on safety, aesthetics, and roadway lighting design.
The main street will have two lanes. This design will call for a mast arm with 4 section signal dead
Carretera Central Restoration Project
Page 18
and a 3 section signal head. The four section signal head will provide guidance for any vehicles
making a left turn.
3.4 Drainage Recommendations
Project Description
The Carretera Central highway is a crucial thoroughfare on the Cuban island; it traverses the
country from East to West. As much of the island, the Carretera Central has been neglected for
decades and is in dire need of repair/renewal. The Carrera Central Restoration Project aims to do
just that. The major reasons are:
1. This particular roadway affects the Cuban people directly more than any other.
2. The project, once completed, will display the economic power of good roads.
3. This project will serve as an example for all subsequent roadway reconstruction and
renewal projects.
The major components of the renewal project are pavement design, traffic operations, drainage,
mast arms and constructability procedures. With this project, the teams hopes to illustrate to a
new Cuban regime the benefits of infrastructure spending, and how it directly leads to the stability
of the Cuban future.
Project Location
The limits of this project are along the Avenida 51 within the city of Havana limits between
Avenida 202 and Calle 222 .This particular location was chosen because it will illustrate how a
renewal project occurs while the city goes about its normal business. Some interruptions will
Carretera Central Restoration Project
Page 19
undoubtedly occur, but the renewal will continue and the local residents will see the improvements
first hand.
Existing Drainage
Much like the rest of the country, roadway drainage has been neglected for decades. Within the
city limits antiquated versions of inlets, catch basins, pipes and retention/detention areas are in
urgent need of a refresh. From a simple bird’s eye view, a typical observer can see age, cracks,
potholes and failures from beginning to end. During the typical rains of a tropical weather system,
the drainage system fails and water collects at low points on the road. The existing structures and
mitigations are not in good enough condition to handle the storm water and the streets flood.
Proposed Drainage
The Carretera Central Restoration project will include a brand new drainage system. A set of
roadside inlets will drive storm water away from the roads into a network of catch basins. The
catch basins will then transmit water into either French drains or will outfall into nearby
retention/detention areas. The main objective of this drainage system is to keep it as simple as
possible. The new government regime, especially in the first few years will need simple to
implement, and simple to maintain systems. The beauty of this system is its simplicity and its
familiarity. The plan is essentially to replace the current drainage system with a very similar one,
but more efficient and easier to maintain.
Design Criteria
The chaos following a change in regime on the Cuban island will mean a regulatory system for
infrastructure might to take full shape for a few years. The first place Cubans might and should
Carretera Central Restoration Project
Page 20
look is the excellent regulatory authorities in the State of Florida: The Florida Department of
Transportation (FDOT), Miami-Dade County Environmental Resources Management (DERM)
and South Florida Water Management District (SFWMD). Several other agencies provide
excellent guidance as to roadway drainage, but the FDOT, DERM and SFWMD are the
overarching agencies responsible for drainage.
FDOT
Although FDOT only holds jurisdiction over the state of Florida, the information they collect,
collate and publish serves as an excellent starting point for designing roadway drainage:
Exhibit 9
Storm Event Rainfall Depth (in)
FDOT, 10-Year/1-Hour 3.5
FDOT, 10-Year/8-Hour 6.4
FDOT, 10-Year/24-Hour 8.88
FDOT, 10-Year/72-Hour 12.5
FDOT, 100-Year/1-Hour 5
FDOT, 100-Year/8-Hour 9.6
FDOT, 100-Year/24-Hour 13.44
The above information again is specific to Florida, but the proximity of the Cuban island to the
peninsula allows designing to at least use the information as a starting point.
SFWMD
To repeat, SFWMD only holds jurisdiction over the State of Florida, however, Permit Volume IV
provides useful guidance as to roadway drainage in most tropical climate situations:
Carretera Central Restoration Project
Page 21
For wet detention systems, the first one-inch of runoff from the project or the total runoff from 2.5
inches times the percent impervious, whichever is greater, must be detained on site. A wet
detention system is a system which maintains the control elevation below one foot from the
seasonal high ground water elevation and does not bleed-down more than 0.5 inch of detention
volume in 24 hours.
Dry detention systems must only provide 75 percent of the required wet detention volume. Dry
detention systems maintain the control elevation at least 1 foot above the seasonal high ground
water elevation.
Dry retention systems are required to provide only 50 percent of the wet detention volume.
For projects with more than 50 percent imperviousness, discharge to the receiving water bodies
must be made through baffles, skimmers, or other mechanisms suitable for preventing oil and
grease from discharging to/or from the retention/detention areas.
DERM
DERM also provides guidance as to roadside drainage and the handling of stormwater; 100
percent of the first inch of runoff must be retained on site. This volume is equivalent to retaining
1 inch of runoff from the furthest hydrologic point in the project. The methodology for estimating
this volume is outlined in DERM’s Policy for Design of Drainage Structure dated December 1989
as follows:

Conclusion
The chaos of regime change on the island will be like nothing ever experienced before. The
Carretera Central Restoration project will illustrate the benefits, both economic and social, that an
infrastructure project can bring to a country, itself finding its way through a political renewal of
sorts.
The design of the roadway, and its drainage system, will be simple, efficient and easy to maintain.
More importantly, the design process borrowed from its northern neighbor will allow the Cuban
government to repeat the reconstruction/renewal project ad infinitum, slowly improving the
economic situation on the island.

4.0 Roadway Construction
4.1 Construction Management (Contractor/Sub-Contractor responsibilities; Permitting;
Utilities)
EACC Engineering has developed a simple but comprehensive Management Plan to deliver the
Carretera Central (Avenida 51) Roadway Reconstruction project meeting or exceeding the time,
money and quality goals of the district as follows:
Maintain at all times close communication with the Ministry of Construction in Cuba:
The Ministry of Construction is to be kept constantly up to date on the progress of the work and
the resolution of all open issues by the Senior Project Engineer thru emails, phone conversations
or as directed. At a minimum, the following will be discussed with the Contact Head of this
department:
Extra Work Issues
Delays/Impacts Issues
Controversial Public Involvement Issues
Work Orders and SA’s
Monthly Progress Estimates
Invoices
At all times the head of this department will be aware of any significant issue's on the job so there
are no surprises and/or misunderstandings.
Carretera Central Restoration Project
Page 24
Staff with intricate knowledge of plans/contract provisions:
Each and every member of the EACC Engineering team will know the plans, special provisions,
standard indexes, supplemental specifications to ensure at all times the Contractors awarded the
project receive clear direction of the contract requirements. The overall intent is for each
Contractor to build the project right the first time, eliminate rework and any potential
controversies which could slow down the progress of the work.
Ensure the Contractor/Sub-Contractor is building the project from the latest plans:
Our contract support specialist will develop a unique spreadsheet to track all plan revisions and
ensure these revisions are incorporated into the contract by either a corresponding work order
and/or Supplemental Agreement. EACC Engineering will take the lead in ensuring an as-built set
of all plan revisions is updated constantly and that all the construction staff has the latest plans for
each and every construction operation they are inspecting. EACC Engineering will ensure at all
times that the Contractors foremen and their subs are building the project from the latest plans
(this will be discussed constantly in the weekly progress meetings).
Strict adherence with all Environmental and Permit Requirements:
This is a critical consideration for the Avenida 51 Roadway Reconstruction project. EACC
Engineering will ensure the Contractor is complying at all times with the Contract Permit
Requirements utilizing, only as a guide, the specifications of the United States NPDES (National
Pollutant Discharge Elimination System) and the specifications of SFWMD (South Florida Water
Management District) to avoid at any cost the stoppage of the work due to a permit violation. We
will ensure the Contractor complies with the approved Erosion Control Plan. Placement of staked
Carretera Central Restoration Project
Page 25
silt barrier will be enforced all along the project prior to any clearing and grubbing and/or any soil
disturbance operation. Proper vibration monitoring of buildings will take place whenever deemed
necessary according to the FDOT Standard and Specifications book as a guideline. The
appropriate erosion control weekly reports will be obtained from the Contractors prior to the
weekly progress meeting for review.
Run Effective Progress Meetings:
The meetings will ensure:
The Contractors receive at all times clear direction to the scope of work and the intent of
the plans so there are no misunderstandings and can proceed with the construction
activities without delays.
Resolve all issues affecting progress expeditiously.
EACC Engineering will request the contractors to provide a 3 week look ahead schedule at
the weekly progress meeting so we can then insure each and every activity can proceed
accordingly without any delays.
All project documentation affecting an upcoming construction activity to be secured in
place prior to commencement of the activity in order to avoid schedule impacts or delays,
i.e., Storm Water Pollution Prevention plan to be approved prior to clearing and grubbing
operations.
Proactive Approach to Survey of Project Related Issues:
EACC Engineering will employ longitude surveyors to identify problem areas prior to the start of
certain construction operations. Proper verification to protect specific environmental landmarks
Carretera Central Restoration Project
Page 26
(i.e. specific tree's and parks) prior to the start of construction is a highly prioritized item of work.
As mentioned earlier, EACC Engineering will coordinate with the Ministry of Transportation of
Cuba's coordinator to field verify the extent and boundary of these items on-site. Longitude
surveyors will be available as a cross reference. In addition, the quantity tracking of subsoil
excavation will be strongly kept up to date weekly with the contractor and Longitude surveyors
will be available to assist to assure there aren't any quantity discrepancies.
4.2 Phases of Work with focus on MOT (Maintenance of Traffic) and the Public
Outreach
The Carretera Central (Avenida 51) Roadway Restoration project will effect one-mile length of
roadway between Calle 222 and Avenida 202. EACC Engineering realizes that this is a major
roadway so prioritizing the travel way of the citizens is at utmost importance. Additionally, EACC
Engineering understands the historical nature of this roadway and will ensure that the contractor
proceeds with the highest caution. Due to the nature of the situation we will be breaking up the
project into three major phases. If we deem it necessary, EACC Engineering will construct sub-
phases, i.e., "Phase 1A," accordingly and notify the Contact Head of the Ministry of Construction
with any documents and plan revisions with enough time in advance. Furthermore, due to the
inability of obtaining reliable underground utility information, EACC Engineering will go ahead
with performing Subsurface Utility Engineering (SUE) in all phases with construction. This will
eliminate unexpected conflicts with utilities and reduce delays and costs. Furthermore, attention
will also be paid to ADA standards and specifications for sidewalks and crosswalks.
Carretera Central Restoration Project
Page 27
Phase 1
This phase will concern itself with the closure of all the northeast bound lanes within the
project limits transforming the multi-lane roadway into a two-way, two-lane roadway
through the southwest bound lanes. This work will be performed at during non-peak hours
throughout the night. The project will separate itself from the roadway utilizing temporary
concrete barrier walls, (see as an example the FDOT spec below for temporary concrete
barrier wall placement through the project limits). After closure, all the work necessary on
that side of the roadway will be taken care of, i.e., excavation, drainage, roadway base
foundation, drill shafts, lighting, asphalt paving, signs, etc.
Exhibit 10
Temporary Concrete Barrier
Carretera Central Restoration Project
Page 28
Phase 2
With completion of Phase 1, Phase 2 will be put into motion. This phase implements a
traffic switch where the roadway will be closed at night during non-peak hours to open the
northeast bound lanes and close the southwest bound lanes (a proper delineation/detour of
traffic during this time will be provided like the one exampled below). After this work is
completed, all the necessary items of work shown as examples in Phase 1 will now be
completed for this southwest bound portion of the project limits.
Exhibit 11
Detour Plans
Carretera Central Restoration Project
Page 29
Phase 3
After completion of Phase 2, Phase 3 consists of another nightly traffic switch during non-
peak hours but this time will contain restriping to the permanent configuration of the
roadway. Furthermore, this nightly shift will be used to construct the final friction course
layer of the roadway along with the reopening of all lanes.
To assure that these phases of work go as smoothly as possible, EACC Engineering will be
utilizing multiple Portable Changeable Message Signs (PCMS) to notify the public around the area
weeks in advance of the work that will be done along the roadway. Also, weeks before each new
phase these PCMS's will be used to allow the public better understanding of the type of roadway
shifts that will be occurring.
5.0 Budget
Based on the information provided by EACC Engineering, as well as making some project design
assumptions, we estimate that the cost to design and construct this segment of Avenida 51 is likely
to cost $4,000,000.00 USD. The approximation of the cost of this project was based on the FDOT
Long Range Estimation System for a new construction undivided four-lane road with paved
shoulders. In order for Cuba to maintain this transportation infrastructure, it will be ideal to create
a Highway Trust Fund (HTF). The majority of these funds should come from user-related taxes
and fees, also this account will not only help maintain the roadway it will also help to improve
other roads in Cuba.
Carretera Central Restoration Project
Page 30
6.0 Conclusion
The restoration project of Avenida 51, will make an impact on the economic growth of Cuba and it
will be the building block to restoring this highway. EACC Engineering can conclude that by
helping Cuba redesigned their highways and roads in accordance to Department of Transportation
standards will allow the country to improve roadway safety for drivers and pedestrian. Increase the
transportation of goods, and attract tourist which will help boost the country’s income.
