During this period Iglesias Vazquez & Associates, PSC served as Construction Inspector, CMA Architects and Engineers, LLC as Supervision and Authority for the Financing of the Infrastructure of Puerto Rico as Construction Manager. URS Caribe, LLC performed the Construction Plans and Specifications however this company is no longer working for the project. The Owner of the project is Corporación del Proyecto ENLACE del Caño Martín Peña (ENLACE). Highlights of the month: 1. The time extension was negotiated and included as part of the Change Order A. This time extension moves the Substantial Completion Date from July 16, 2020 to May 31, 2021. 2. The PREPA staff visited the project to perform the coordination of vias libres in order to complete de system electric connections. Accomplishments of the month: 1. The Change Order A, which includes costs of 10 items, was approved by AFI. 2. The Shop Drawing #22, Storm Sewer System was approved as noted by the Supervision. Rev. 04/2009 6 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. Rev. 04/2009 7 Monthly Inspection Report #11 July 2020 Project: PASEO DEL CAÑO NORTE PHASE I: REALIGNMENT OF THE BARBOSA AVENUE, SAN JUAN, PUERTO RICO 2. Four weekly construction meetings were held through Microsoft Teams platform because of COVID-19. 3. The RFI #15, related to buoyancy of the storm sewer catch basins, was answered by Supervision. In general, the drainage structures base extensions were requested to compensate the buoyant force. The Supervision concluded the following catch basins 4, 5, 6,10, 11,13, 14, 15, 16, 19, 21, 23, 24, 25, 26, 27, 28, 29, 30, 31 and 32B has no buoyancy problem using the received catch basin structures.

Ошибка связи.RFI Log: RFI # Description Originated by (GC, Insp, Des, Owner, Management) Date Submitted to Inspection Date Returned to Contractor Total RFI Cycle in Days Summary of RFI 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 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. 3. Existen parillas en las rampas de impedidos. GC 24-Sep-19 30-Sep-19 6 2 El Contratista solicita acción sobre los vehículos inservibles en el área del proyecto ya que esta ocasionando atrasos en el proyecto. GC 1-Oct-19 4-Oct-19 3 GC 1-Oct-19 4-Oct-19 3 La Inspección le solicita al Contratista qué información se esta requiriendo. 3 4 5 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. GC 3-Oct-19 4-Oct-19 1 La hoja UTE-3 no instruye a remover la toma de la residencia #574. Favor notar que la Hoja UTE-3 es la hoja de Condiciones Existentes y Demolición. Los elementos eléctricos a demoler/remover están identificados con el indicativo [-R-] que se ilustra en la leyenda eléctrica (Hoja UTE-1). GC 3-Oct-19 22-Jan-20 111 La AEE avalo el plano del proyecto en la reunión preconstrucción y la autoridad asignó un Inspector de la AEE. 6 Se esta requiriendo como proceder con la construcción de la subbase de la sección de calle ante un nivel freático de menos de dos pies de profundidad. GC 21-Nov-19 27-Nov-19 6 7 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. GC 23-Jan-20 4-Feb-20 12 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. Rev. 04/2009 15 Monthly Inspection Report #11 July 2020 Project: PASEO DEL CAÑO NORTE PHASE I: REALIGNMENT OF THE BARBOSA AVENUE, SAN JUAN, PUERTO RICO RFI # 7 8 9 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. Originated by (GC, Insp, Des, Owner, Management) Date Submitted to Inspection Date Returned to Contractor Total RFI Cycle in Days GC 12-Feb-20 18-Feb-20 6 GC 27-Jan-20 7-Feb-20 11 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. Insp 10-Feb-20 17-Feb-20 7 10 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. GC 18-Feb-20 10-Mar-20 21 11 El Contratista solicita el detalle del punto de conexión del nuevo sistema pluvial a la estación de Bombas Rexach existente. GC 21-Apr-20 24-Apr-20 3 La Supervisión provee el detalle del punto de conexión solicitado. GC 20-May-20 27-May-20 7 Escarificar 0.05 metros el área, ajustar la rasante o nivelación con asfalto de base hasta un máximo de 0.15 metros sobre el nivel escarificado GC 29-May-20 12 13 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. 14 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. GC 29-May-20 16-Jun-20 15 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. GC 24-Jun-20 1-Jul-20 18 7 El contratista sometió el detalle de estabilización de subbase según se muestra en el Anejo A - Typical Section Line #1. La misma se acepta modificando el material de establización no. 5 y 6 según se muestra en el recuadro del mismo detalle - Stone Revetment Filter Material Type B Material – Spec 718 of PRHTA.
