Ítem Criterios de la interventoría administrativa para el seguimiento y control de las obras de conexión intradomiciliaria de acueducto y alcantarillado en viviendas de estratos 1 y 2 de 3 municipios de la Región Caribe colombianaAvendaño Barrera, Alejandra; Escudero Eguis, Kelly Johanna; Mariño Alvarado, María Fernanda; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]The execution of intradomiciliary aqueduct and sewage connections is carried out through inter-administrative agreements between MinVivienda and ENTerritorio, that conducts construction contracts and auditing contracts. Shortcomings have been identified related to delays in the reports’ delivery time for the supervision of ENTerritorio, generally having incomplete information and not meeting the required criteria. This project generated a more assertive document management in the follow-up and control processes carried out by the construction supervisors in their administrative functions on the contracts. As a result of the project, an Excel template was created for the presentation of weekly and monthly reports, which streamlines the processes of uploading and processing information, as well as an audiovisual use guide for the personnel in charge.Ítem Criterios de revisión por la interventoría de estudios y diseños para el cálculo de la administración de obra en proyectos viales para mejoramiento de barrios en la ciudad de BogotáGonzález Camargo, Luis Alejandro; Sierra Hernández, Edwin Fernando; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]In this degree work, the criteria for review by the Study and Design Supervision Office are determined, of the calculation of the costs of administration of works for road projects for the improvement of neighborhoods in the City of Bogotá D.C. The analysis is carried out based on 30 real cases of this type of project. As an example, a case study is presented. As a result, an instruction manual is delivered in which the aspects to be taken into account for said calculation are established and is accompanied by the templates for obtaining it.

This is evidenced by civil and industrial works and the construction of buildings for various types of uses. Therefore, the government invests in these types of projects with the aim of providing economic support to regions and well-being to society. It is observed that, during the planning stage for the construction of different projects, there is a lack of proper oversight, supervision, and control required in the consulting process for their design and construction, leading to inadequate execution of works, resulting in serious economic consequences and impacts such as increased work quantities, unforeseen items, etc., and prolonged completion times for the projects. Therefore, it is necessary to understand the importance of oversight and supervision in the development of planning and consulting processes for projects in Colombia, as well as the scope and competencies involved, the measures to be taken, and the responsibilities assumed by the professional; one of its objectives being to establish the relationships between the contracting entity and the contractor to ensure compliance with the required needs without omitting aspects such as quality, resources, and duration. Therefore, through the development of this monograph, the aim is to propose a strategy for the supervision of a public works contract during the project planning stage, taking as a case study the construction of two military housing buildings for National Army personnel in the municipality of Nilo, Cundinamarca, based on the study of unfavorable situations that have occurred in the execution of the contract.Ítem Estrategias de control y seguimiento de interventoría técnica en la fase de ejecución de proyectos de renovación de redes de acueducto y alcantarillado sanitario en tubería PVC por método de zanja abierta en proyectos realizados por la empresa de servicios públicos del municipio de Girardot Cundinamarca ACUAGYR SA ESP.(Universidad Distrital Francisco José de Caldas) Cardona Ortiz, Estefany Geraldine; Herrera Cleves, David Felipe; Avila Bernal, Luis Alejandro; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]This application monograph addresses the renovation of water and sewer networks from the perspective of supervision in terms of control and monitoring that must be carried out during the execution process. It is important to highlight that it focuses on the open trench excavation method for pipes in projects carried out by the company ACUAGYR SA ESP in the municipalities of Girardot and Ricaurte Cundinamarca. The company is expected to carry out comprehensive monitoring of the technical processes during the activities carried out in the execution of network renovation works. The objective of the project is to establish control and monitoring strategies for technical supervision in the execution phase of projects for the renovation of water and sewer networks in PVC pipe by the open trench excavation method in projects carried out by the public services company of the municipality of Girardot Cundinamarca ACUAGYR SA ESP.

For which conducted a documentary review and surveys of engineering, architecture and related careers with experience in this type of projects, in order to determine the factors that affect the deviations of the actual cost of the project with respect to the budget base. The La Hacienda 1 multifamily housing project was taken as a case study. located in the city of Soacha, where the deviations presented in the budget, the causes and factors that influenced it, as well as the role of the audit in the control and monitoring of costs.Ítem Influencia de la adición de la cal viva en concretos elaborados con agregados reciclados de concreto(Universidad Distrital Francisco José de Caldás) Landeros Barrera , Juan Carlos; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]The present document analyses the performance of recycled concrete with the use of RCA by product of the crushing of RCD in concrete elements. The research is based on the replacement of 20%, 35% and 50% of the natural coarse aggregate with recycled coarse aggregate (RCA). Likewise, this research proposes the use of calcium oxide or quicklime, as a complementary material for the reduction of cement, which allows the reduction of permeability or porosity in recycled concrete mixtures, thus achieving an increase in durability compared to a control mix. Having said the above, a substitution of 2% and 5% of calcium oxide (CaO) as a cementitious material will be carried out to study the influence that this material has on concrete with recycled aggregates to later compare the results in the hardened state in reference to the resistance to compression, flexure and electrical resistivity for specimens in concrete cylinders and beams at different ages of evolution (7, 14, 28, 56, and 90 days). Finally, perform a qualitative analysis through SEM microscopy testing on three (3) particular concrete mixtures. “Mix #1; 0% RCA – 0% CaO”, “Mixture #9; 50% RCA – 0% CaO” & “Mixture #11; 50% RCA – 5% CaO”.Ítem Informe de auxiliar de ingeniería civil en Transmilenio S.ACobos Hernández, Juan Sebastian; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]The main purpose of this report is to demonstrate the activities carried out during the time it takes to develop internships as a technologist, where will implement the theoretical knowledge acquired during the classes, trying to in turn apply them to future activities to be carried out, in order to obtain the title technology in civil constructions and through this opportunity will have the first approach to working life.

The objective of the following instructions will be for the reader to establish the acceptance and rejection criteria for the execution of the construction activities of the parking lot floor and construction of the buried tank of the project carried out by the legally constituted company LONGIENERIA, where a methodology will be presented. similar to that carried out in the project, said methodology will present adjustments in compliance with the standards of each of the activities carried out, in addition to how the theory learned during the Civil Construction Technology degree is of vital importance so that each process and execution is the most appropriate for the activities carried out.Ítem Introducción de BIM en la interventoría del consorcio Casa de la Cultura 2019Estupiñan Rojas, Geraldine; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]Carrying out the responsibilities and obligations that are deployed in the auditing area require a high degree of commitment and transparency for those who develop and adopt the role of this, ideally, that their exercise is carried out objectively and satisfactorily with the specifications and agreements established in the project to intervene. In this case, the 2019 House of Culture Audit Consortium is awarded the technical, administrative, financial and legal supervision of the public works contract whose purpose is the construction of the House of Culture of the municipality of Nimaima Cundinamarca. Based on this, through active participation as an intern, the opportunity to develop personally and professionally in the field of civil construction learning is provided, accepting new challenges and knowledge collected and reflected in this work. Through the assignment of review tasks and verification of detailed information from the existing design plans in comparison with what was built and evidenced in the progress registered in the work, in order to structure and elaborate the 3D modeling of the construction with the purpose of use of material and data collected in plans, photographs and project specifications, which in turn automatically allowed the generation of work quantification information as modeled. The foregoing, as a reason to introduce the Nimaima culture house project in the use of tools implemented in construction information modeling (BIM). Taking into account the importance that the application of this methodology demands today in projects in the construction area, that with the passage of time its implementation has become a mandatory requirement in any type of work, as a key sign of progress. quality of work it is necessary to review it, investigate it and encourage knowledge of it.Ítem Metodología de seguimiento y control para la interventoría técnica en proyectos de reforzamiento estructural para casas de uno y dos pisos de material adobe y tapia consideradas patrimonio culturalCuervo Castillo, Giselle Zulay; Silva Pico, Johana Maritsa Johana Maritsa; Páez Molina, Sandra Paola; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]In the Colombian territory there are many buildings considered as cultural heritage, which are the history of any city and according to current regulations NSR-10, most of this type of buildings and structures, were made under the absence of technical criteria, which implies that they are structures vulnerable to earthquake events that can present failures in their construction system and affect the integrity of the people who are making use of it. From a professional perspective and framing the features of Colombian history and its different stages, a methodology was carried out so that the technical audit carries out control and monitoring of structural reinforcement projects, for structures of one and two-story houses built in material of adobe and rammed earth considered cultural heritage, where we will seek to make a difference that will not only allow us to comply with the parameters established by the standard, but also to contribute positively to the recovery of cultural heritage buildings.Ítem Metodología para el control y seguimiento administrativo de la interventoría durante la ejecución de obras de ampliación a instituciones educativas en el sector públicoPacheco Valderrama, Roniel Javib; García Góngora, Juliana Valentina; Hernández Rojas, Luis Felipe; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]As it is currently known and under the legal regulations, in public contracting it is necessary to award supervision contracts for the correct monitoring of the activities that are carried out in the construction contracts. In this sense, it is relevant to study and/or evaluate certain aspects of this activity carried out by many professionals within the Colombian state. To focus more specifically, the proposed degree work aims to emphasize the subject of Administrative Audit, one of the different functions that are assigned in a specific contract and one could almost say that one of the inevitable to carry out audits of a character public and to the education sector. This degree work proposal arises in the first instance due to the deficiencies evidenced within this administrative area which includes all the monitoring and control of aspects of a work contract and are evidenced in the face of delays, downtime, ignorance of scope, among others. It is for these reasons that it is considered pertinent to implement a methodology for the controllers where they can carry out their daily functions in a simple way and demonstrate to the entity, the contractor and/or any other control entity that they are in all the faculties and really lead to the day that monitoring and control of administrative activities of which no reprocesses are generated, and rather, it is intended to give agility and speed to all the consequent tasks that it entails.Ítem Metodología para el seguimiento y control de la interventoría técnica, en la fase de ejecución, de proyectos tipo vivienda vis construidas en mampostería confinada en el Municipio de Ambalema Tolima, caso de estudio: Urbanización Villa Eduardo.Vélez Trujillo, Carlos Eduardo; Martínez Sánchez, Ricardo Alfonso; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]The present work aims to mitigate failures of the audit of the one-story social housing project in confined masonry located in the Villa Eduardo urbanization in the municipality of Ambalema-Tolima, from the technical point of view. It is well known that many professionals, both auditors and builders, lack the minimum experience required for these positions, in addition to the fact that throughout the project audit and construction companies have been changed, added to the lack of connections between the companies has created various errors of an economic, time and technical nature, the latter will be the ones we will focus on.Ítem Pasantía como auxiliar de ingeniería enfocada en obras civiles y apoyo en licitaciones de consultoría, interventoría y obras en la empresa Consorcio Ingenieros CAZuleta Hernández, Brayan Steven; Mena Serna, Milton; Mena Serna, Milton [0000-0002-7377-2787]The following work collects information made during the internship at Consorcio Ingenieros CA. The central issue is the public tender under construction (either interventoría, consultoría or obra) in Colombia through which contractors around the national territory access their respective contracts and through which the infrastructure of the country is developed. In order to contribute as a student with a view to graduating from technology in Civil Construction, it is decided to make a basic guide for the execution of bids through the bidding modality, the work is developed with the knowledge acquired during the internship and through separate research. Currently the Colombian State has two platforms for the realization of public offers SECOP I and SECOP II, , through both platforms the entities publish their draft documents, which contain the necessary information for each bidder to submit their offer. In SECOP I physical documents are delivered, SECOP II for its part, uses the platform developed by the Public Service to file the requested documents.
