Monthly Inspection Report #11
July 2020
Project: PASEO DEL CAÑO NORTE PHASE I:
REALIGNMENT OF THE BARBOSA AVENUE, SAN JUAN, PUERTO RICO
Weather Conditions:
The Tropical Storm called Isaac, which passed to the south of Puerto Rico, affected the
construction activities on at least three days.
Construction Activities:
The Contractor performed the following construction activities:
1. Marked survey points on the project along Line 1 in order to outline the geometry
of the Barbosa Avenue realignment.
2. Performed finishes at sanitary manholes #1 and #4.
3. Performed unclassified excavations for the construction of subbase at Line 1.
Problems Affecting the Project:
1. Several months ago, the Contractor generated the RFI #6 requesting how to
proceed to the construction of the subbase of the propose street because of the
presence of water at the excavation. The Supervision recommended to perform a
geotechnical study and it was conducted through the Contractor and included as
part of the Allowance #8. As requested by the Supervision, GMTS performed two
additional borings and a preliminary repost was submitted last week. This study
recommends the improvements of the soil sublayer at the roundabout area in
order to avoid bothprimary and secondary settlements. Stone columns has been
recommended to improve the subsoil and thus avoid the above-mentioned
settlements. Thus, geotechnical companies are been contacted to provide its
proposals and are under evaluation. The Contractor submitted a cost proposal of
$1,708,647.63 to provide stone columns at the affected area. ENLACE has not
yet assigned the budget for this work.
2. The project does not have the endorsement of the Negociado de
Telecomunicaciones de Puerto Rico. The Inspection is looking to obtain the
information of the corresponding telecommunications providers in order to
identify the affected telecommunication infrastructure at project site.
3. The RFI #13, related to the connection point of the storm sewer system at the
Pump Station Rexach (Construction Sheet DR-1A), was submitted on May 2020
by Contractor and has not been answered by the Supervision because of the
Municipio Autónomo de San Juan endorsement.
Project Status:
The project currently has 17.7% of physical progress and the time elapsed is 50.9%.
This percent of time elapsed is considering the time extension awarded in Change
Order A.
Remarks:
1. According to the latest progress scheduled the critical path of the project
corresponds to the activities related to the storm sewer system.

Answer
1. Pocetos con espacio insuficiente
para la tubería especificada: Favor
realizar el mismo ejercicio
considerando dos tuberías paralelas
de 15”Ø en lugar de una de 18”.
Una segunda alternativa implicaría el
re-diseño del sistema pluvial y de la
nivelación (“grading”).
2. Pocetos tipo 1 en areas verdes:
Considerar el uso de Poceto/parrilla
tipo 4 o tipo 5 de los dibujos
estándares de la Autoridad de
Carreteras (Drainage Inlet Type 4 /
Drainage Inlet Type 5 – Depressed
Grass Median).
3. Pocetos en rampas de impedidos:
Como primera opción se debe
considerar hacer pequeños ajustes de
localización bien sea de la rampa o el
poceto y documentar dichos ajustes
en los dibujos “As-Built”.
En los casos, si alguno, en que no se
puedan realizar ajustes menores no
tenemos objeción al uso del tipo de
parrilla propuesta por el suplidor (USF
4122 Frame / 6172 Grate).
Se notificó al Contratista que en
reunión semanal de proyecto del 18
de septiembre de 2019, se estableció
entre todas las partes que la fecha
límite para remover los mencionados
vehículos (por parte de los residentes)
es el 4 de octubre de 2019. Además
se le indicó al Contratista que para
poder atender este asunto sería
necesario que se someta el CPM del
proyecto y así evaluar las actividades
críticas que se estarían afectando.

1. En algunos casos la tubería pluvial que
entra resulta más alta que el tope de los
pocetos donde serían conectadas.
2.Las parillas pluviales en áreas verdes no
son especificadas para áreas verdes.

El Contratista notifica que una de las
estructuras a demoler esta ocupada por
una persona por lo que presenta un riesgo
de seguridad.
En los planos demolición (UTE-3) se
indica que se debe remover la toma
secundaria que alimenta la residencia
#574. Mientras que la hoja de mejoras
eléctricas (UTE-4) no indica donde será
conectada dicha residencia. Favor de
aclarar de donde se alimentará la toma
para esa residencia.
Se solicita los planos eléctricos
endosados por la AEE. Los planos
eléctricos del proyecto de referencia no
cuentan con el sello de endoso de la
Autoridad de Energía Eléctrica. El diseño
tiene una revisión con fecha del 26 de
abril de 2017 con una nota de que fue
sometido nuevamente debido a que la
aprobación había vencido.

En visita al campo con el inspector Ángel
San Inocencio de la AEE se pudo
observar que los pedestales soterrados
del alumbrado donde sería el punto de
conexión (hoja LT-2) las tuberías no
contienen cabrería secundaría. Se
observa que la infraestructura soterrada
fue abandonada y se conectó el
alumbrado aéreamente. Se solicita como
realizar la transición de la línea secundaria
aérea a soterrada.

El Diseñador contesta que se refiera a
la nota 15 de la hoja de plano GR-2
donde indica que el contratista debe
proveer 10”de gravilla en las áreas
que estén afectadas por el agua.
Añade que el Contratista es
responsible de el bombear el agua
encontrada al pluvial mas cercano.
Si se requiere mantener la instalación
soterrada ilustrada en los planos de
URS habría que alambrar los tramos
hasta cada subestación de alumbrado
y rehabilitar los controles de
iluminación lo cual no es parte del
ámbito de construcción actual.
Entendemos que la solución más
económica es continuar con la
instalación aérea con triplex #1/0 en
aluminio. Es importante que antes de
proceder con esta recomendación se
consulte el asunto con el personal de
la AEE.

Description
1. Hacer una conexión aérea en postes de
aluminio no es un patrón de construcción
de la AEE.
2. En cuanto a la medicion del sistema,
como ya se comprobó que las
subestaciones no están en servicio porque
fueron vandalizadas, la solución tiene que
ser consultada con la AEE por la persona
que asuma la responsabilidad del diseño.
Esto es un cambio a las condiciones que
se habían considerado en el diseño.
En los planos del proyecto en la línea 7
conexión de la Ave. Constitución con la
Ave. Barbosa se muestra un box culvert,
el mismo según se observa no afecta los
trabajos. Sin embargo, al realizar el
marcado de agrimensura esta estructura
si afecta la construcción del rodaje el
paseo de bicicleta y la acera. Se solicita
como proceder.
Los documentos contractuales incluyen la
realineación de la avenida Barbosa a
través de la Línea 1 según la hoja GR-7.
En la intersección de la avenida Barbosa y
la calle 1 está ubicado un semáforo
intermitente el cual está colgado de un
cable y a su vez este cable está adjunto a
dos postes existentes los cuales no están
identificados en los planos. Uno de los
postes se afecta por la construcción de la
realineación.

Summary of RFI
Answer
Estamos conscientes de lo expresado
en los puntos 1 y 2. Es por esa razón
que propusimos consultar el tema con
la AEE en aras de intentar que se
provea la solución menos onerosa
para el dueño. De no ser aceptable
para la AEE o para el dueño realizar
otra cosa que no sea lo que se ilustra
en los planos originales de URS,
habría que hacer lo que indicamos en
la respuesta original al RFI.
La Supervisión envió un rediseño de
la rotonda en formato .dwg
El poste en cuestión soporta un
semáforo de luz intermitente sobre el
cruce de peatones desde la calle Las
Mercedes hacia la calle del Pilar. En
el diseño de URS este cruce de
peatones se elimina (se mueve más
adelante) y no se contempla ningún
semáforo en esta intersección. Para
ejecutar lo que ilustran los planos de
URS será necesario remover este
poste.
Se debe proveer una nueva
subestación de alumbrado (25 KVA)
montada en poste que incluya una
base de metro contador de la AEE y
los contadores requeridos para la
conexión y control de las luminarias
ubicadas dentro del área del proyecto.
Las luminarias existentes del proyecto
permanecerán conectadas de forma
aérea como están.

La AEE indicó que los puntos de conexión
del alumbrado actualmente no cuentan
con equipo de medición. En los planos no
se contempla equipo de medición para
esos fines por tal razón sometemos el
siguiente RFI para que se aclare y se
consulte con la AEE la localización.

Mientras se realizaba la excavación para
la instalación del SMH #1, se encontró
piedra debajo de la base de asfalto. El
Contratista solicita como realizar la
transición de la calle existente con la
propuesta
En la hoja revisada DR-1A del sistema
pluvial se muestra la conexión de la
tubería de 30” al sistema de bombeo
existente. Se solicita si seria necesario la
instalacion de una parilla antes de llegar al
pit.

El Contratista solicita que se aclare que se
sustituyen las 10” de grava, según
especificado en la nota 15 de la hoja GR/2
por 12” de material “Aggregate Base
Course Class A”, PRHTA Spec 703-4.

Por este medio se les solicita la razón por
la cual se nos solicitó en los dibujos de
taller para los inlet para el sistema
pluvial, extender la base de los mismos
unas 6” y otras 1’. Ya que la fábrica
“Atlantic Pipe” no cuenta con moldes
para esta solicitud, si el propósito es por
flotación Atlantic Pipe puede fabricar los
inlet con base de mayor grueso.

modificando el material de
establización no. 5 y 6 según se
muestra en el recuadro del mismo

The drainage structures base
extension were requested to
compensate the buoyant force. After
receiving the alternate catch basin
structures via email on June 26,2020
(see drawings included on the email at
the end of this document) we proceed
to perform an evaluation of the
structures buoyancy. After the
evaluation we conclude the following
catch basins 4-6,10-11,13-16, 19, 21,
23-31 & 32B has no buoyancy
problem using the received catch
basin strutures
