When exercising the position of supervisor or auditor with professionalism, it is an important task and one of considerable responsibility, for this reason the importance of acquiring the knowledge and the essential bases to carry out this position. Currently there are many social interest housing projects under construction and even more high-rise buildings, however, incorrect practices and difficulties that arise when implementing industrialized systems stand out, which are undoubtedly a great advantage to build in times record and at lower costs. In the present work, common failures will be observed in a social interest housing project built in an industrialized system, as well as a photographic record of the most relevant activities of its construction process, the evaluation of problems, the normative analysis that govern this system, a guide graphic for the control and follow-up of the technical intervention, as well as the respective support formats to carry out this work. Likewise, different works and manuals implemented by different entities of the country regarding the subject will be analyzed, in order to create the bases and adequate tools for those construction professionals who want to expand their knowledge or simply have support tools for their work.Ítem Método para el control y seguimiento de la supervisión técnica en la fase de ejecución para las etapas de: recepción, colocación y curado de concreto premezclado; caso de estudio: casa de la cultura municipio de Acacias, MetaCardozo Barrera, Marco Antonio; Rey Agudelo, Edwin Ricardo; Mena Serna, MiltonIt seeks to guarantee quality and efficiency in the construction of structures of ready mixed concrete. This work arises in response to the need to improve the control and monitoring processes in the execution phase of construction projects, in which requires the use of premixed concrete in its different stages as follows: Reception, Placement and curing. The methodology focuses on establishing a control and monitoring system that allow technical supervision and continuous monitoring of the production process, placement and curing of ready-mixed concrete. For this, the development of a application guide for quality control that allows identifying critical variables in the process in its different stages and guarantee the conformity of the application of good practices of ready-mixed concrete with established technical specifications. The expected results of this work are significant for the health sector. construction, since the application of the methodology will allow improving the quality of the premixed concrete used in the construction of structures, which results in a greater durability and resistance. Furthermore, it is expected that the methodology proposal contributes to the reduction of construction costs and times, as well as reduce the risks of structural failures.Ítem Desarrollo de un aplicativo móvil que genere alertas preventivas y correctivas durante la fase de ejecución, en el capítulo de estructura como apoyo en la gestión de la supervisión técnica en la construcción de edificaciones industrializadas tipo manoportableGonzález Galindo, Jennyffer; Montaño Guevara, Wilmar Hernando; Martínez Ramírez, Oscar David; Mena, MiltonThis research addresses the frequent failures in the construction process of portable industrialized buildings and the selection of technical criteria based on the applicable regulations with the objective of structuring a mobile application that provides support to the technical supervision process by generating action alerts. preventive and corrective measures during the execution phase of the structure chapter of the buildings in question, the above responding to the identified problems.Ítem Estrategia de revisión para el control técnico topográfico en interventoría de proyectos de infraestructura metálica en acero durante la etapa de construcciónHerrera Gómez, Jeisson Fernando; Mena Serna, MiltonThis document proposes a strategy for the technical audit in the topographic control during the construction stage, thus verifying that the implementation of the assembly of the braced gantry steel structure, based under the review parameters to the provisions of the Colombian technical standard NTC 5832:2012 Standard Practices for Manufacture and Assembly of Steel Structures. Buildings and Bridges meet the minimum requirements that are manifested therein. Based on these procedures and methodologies for the review of steel metal structures, a strategy will be developed that will have verification criteria with respect to tolerance orders allowed by NTC 5832:2012, NSR-10 (Chapter F), NTC 6271:2018 and other regulations that guarantee tools for technical supervision according to the auditor during the execution stage of the work.Ítem Estrategia para el control y seguimiento de la interventoría técnica, para la construcción de edificaciones vis en mampostería parcialmente reforzadaLara Hernández, Jesús Antonio; Mena, MiltonEach construction project has a process of carrying out activities, which are constituted and directed in order to successfully complete the work. In the development of the activities, a very important role is played by the construction and audit inspectors, since they are the ones who ensure that the construction is being fully carried out, taking as reference the work booklet supported by the designer. The inspection by the Auditor of the construction processes and of each of the materials that make up the structure that have physical and chemical properties, such as vertical perforation masonry, grafils with variable diameters in the horizontal part according to the designer, mortar of glue, reinforcing steel that are conditioned in the NSR 10 standard. Using review methods in the development of construction activities helps optimize the processes in a work, gives reliability of the quality of the structure, these methods can be represented in manuals or guides that are easy to understand for the professional in charge who represents a audit or construction inspector, strengthens knowledge and provides security of the activities carried out. Taking into account that there are various construction systems using masonry, each of the parameters given by the standard (NSR 10) will be taken as a reference. Title D), (Colombian NTC Technical Standard 4026) Through this application monograph proposal, we seek to optimize and provide an inspection strategy with a guide that allows the professional construction and audit inspector to ensure that the activities were carried out according to the designs, complying with the established construction standards with partially reinforced structural masonry.Ítem Estrategia para el seguimiento y control de la interventoría técnica en la fase de construcción de estructuras de contención, tipo pantalla de pilotes, muros estructurales en voladizo y ancladosBravo Guzmán, Cristian Felipe; Cordón Barrera, Osmar Adrián; Forero Buitrago, Diego Fernando; Mena Serna, MiltonGeotechnical engineering encompasses the design and construction of structures in contact with the ground, such as tunnels, foundations and roads, including containment structures that resist the thrust generated by differences in levels in the ground. The growing demand for containment works is attributed to urban growth, the need for road infrastructure in complicated terrain and regulatory rigor. Despite the availability of manuals, they focus mainly on design and lack clear information on construction aspects and acceptance criteria. Consequently, the need for a strategy for the technical supervision of containment structures during their construction arises, integrating the design criteria of Colombian and foreign regulations; This strategy will focus on cantilever structural walls, anchored walls and pile screens. This initiative will provide the auditor with the necessary tools to determine whether a geotechnical work meets the minimum standards compliance requirements during construction and decide on the final acceptance of the finished structure.Ítem Metodología orientada a la interventoría administrativa para el control de proyectos en fase de ejecución en edificaciones con estructura metálica en pórtico arriostrado concentrico caso de estudio Centro de Salud Gachancipá.Acuña Castro, Julián Manuel; Mena Serna, MiltonThis project is presented as an application monograph, with the objective of preparing instructions for the control of administrative auditing in projects of metal structures in braced porches in the execution phase for the municipal health center of the municipality of Gachancipá, taking into account It takes into account the risks that are identified in the projects in aspects of schedule control or execution times and scope of the work for the audit. The purpose of this monograph is to address the problems surrounding the detection and intervention of the intervention in the face of administrative risks in a project focused on metal structures, where we encounter barriers when controlling a work, in this case in its construction stage. execution, which is in turn where the greatest number of variables to be considered for a project are manifested, therefore it is considered pertinent to develop strategies to face these variables, this in order to mitigate delays in time or reduction in the scope of a project. , in turn we find an increase in the construction of metal structures since the 90s in the country, putting this type of structures more and more in the panorama of the audit. As a product of this monograph, an instruction manual is presented, which indicates the parameters to be taken into account to identify the problems in a project, thereby seeking to control the schedule and scope of a project on this page. 7 taking as principles the PMBOK and the Pareto principle. The product that will be obtained from this exercise will be (1) an instruction manual, and several Excel tables which will give us percentages to understand the status of the project.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 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 Estrategia para el control y seguimiento de la interventoría administrativa en la fase de ejecución de proyectos de infraestructura vial correspondiente a la pavimentación de vías urbanas en el municipio de San Martín departamento del MetaCastellanos Echeverri, Rodolfo Steven; Castro Rodríguez, Fidel Ricardo; Sánchez, María Alexandra; Mena Serna, MiltonIt is the responsibility of public entities to control and monitor the execution of contracts that they enter into in compliance with the principles and purposes of the State; this through the figures of supervision and intervention, which Colombian law establishes. That is why all public entities adopt a manual, to serve as instructive. basis regarding the functions, obligations, processes and others, which must be carried out by the audit and supervision, guaranteeing the correct execution of the contracts in accordance with the object. However, since the figure of auditing has been applied in Colombia to control construction works, its function has been developed empirically, given the lack of unanimity of criteria and little regulation. Within the contracting, supervision and auditing manual of the Municipality of San Martín in the Department of Meta, there are gaps and absence of guidelines when exercising administrative control functions, by the auditing office, in the contract execution stage. working. Situation that usually leads to the audit and supervision ending up deciding or omitting documentation when delivering information to the entity, generating deficiency in the activity of the entity. audit, due to the delays in the delivery times of the reports and their quality, which has been present to a greater extent, in the road infrastructure sector, which is characterized by being one of the sectors with the highest investment of public works resources throughout the country. The guidelines regarding the control functions of the audit must be sufficient and clear, specifically in the administrative matter, with the purpose of identifying in a timely manner the specific documentation for the reports delivered to public entities, be they partial payments and advance payment disbursement and avoid concurrence between supervision and auditing in relation to the same contract. The development of current technology has allowed the available digital tools to be useful means for the administrative control of the audit, with which greater efficiency can be achieved in the construction of works, avoiding aspects such as quality failures and corruption, going from the traditional in control activities to the digital that technology provides. Consequently, this work establishes a control and administrative monitoring strategy of the audit, through a selected digital application, that allows documentary control in the processes of partial payments and advance disbursement, for road infrastructure contracts corresponding to paving. of urban roads, contributing to the quality of information, optimization of execution times, timely analysis of information and improvement in administrative processes. This does not mean that, within the study, aspects related to control and monitoring have been addressed in the pre-initiation phase, nor in the liquidation phase, as well as matters related to the technical, financial, legal and environmental component of the audit. , which can be studied in other works.Ítem Metodología para la interventoría técnica en los proyectos de remodelación arquitectónica hospitalaria niveles 1 y 2.Ortega Pérez, Xiomara Leslee; González Pulido, Andrés Felipe; Mena Serna, MiltonThis document proposes to present an instruction manual through which engineers, architects and students who work in construction areas have a practical guide to carry out specific evaluations in architectural remodeling processes, which are very important due to their visual appearance, functionality and adaptation according to the new interests of any building that requires it. Architectural remodeling must have a rigorous evaluation method since, being non-structural elements, they must comply with the parameters established in NSR-10. The implementation of these elements must be supervised since they can represent a risk in any type of event or natural disaster, which is why the instructions contemplate the most representative elements for adequate monitoring, control and quality in an architectural remodeling. Remodeling is fundamental, since it raises the spaces that currently exist to give it a new functionality, due to this, pre-established technical controls must be had when supervising a remodeling, since, many times, the different elements do not meet the specifications. raised, for not being considered an important part of the structure.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. Finally, there are the contributions, recommendations and conclusions of the analysis carried out.Ítem Aplicación de los criterios de la interventoría ambiental para el seguimiento y control del proyecto de construcción de la segunda calzada tramo el Tablón –Chirajara de la carretera Bogotá – VillavicencioAguilar Ráquira, Samuel Alejandro; Mena Serna, MiltonThe present degree work, carried out through the Application Monograph modality, through a case study and in the line of research of the environmental supervision, contemplates the monitoring of the environmental management plan contained in the environmental impact study prepared by the Concesionaria vial de los Andes S.A. - COVIANDES S.A. for the construction project of the second carriageway in the El Tablon - Chirajara section of the Bogotá - Villavicencio highway. In the project throughout its development the following shortcomings have been detected: slippage of slopes causing prolonged closures, affectation in mobility, increase in travel times; collapse of the Chirajara bridge causing loss of life, damage to the soil, destruction of vegetation, pollution and diversion of the Chirajara ravine; mass movements at kilometer 58 producing with it waste on the road and surrounding bodies of water, collapse of bridge 1 dry pipe; banking instability leading to rising transport costs. The highway is divided into three sections, the construction project of the second carriageway is the intermediate section, which is divided into eight sectors, located within the jurisdiction of the municipalities of Cáqueza, Quetame and Guayabetal in the department of Cundinamarca. This project was licensed through resolution 81 of 2010 of the then Ministerio de Ambiente, Vivienda y Desarrollo Territorial, granting the environmental license to the then Instituto Nacional de Concesiones - INCO, today Agencia Nacional de Infraestructura - ANI, and whose license was transferred in its entirety through resolution 1612 of August 19 of 2010 in favor of the Concesionaria vial de los Andes S.A. - COVIANDES S.A, being this, the current holder and beneficiary of the environmental license; The project that is located between the abscissa el Tablon (PR34) and Chirajara (PR63) has presented major problems throughout its development, among them is the constant mass movements that occur at km 58 and that cause the constant closure of the highway, and also, the contingency presented in 2018 when the Chirajara bridge collapse occurred. As of 2021, the total reversion of the project by the concessionaire to the ANI has not yet been made, the completion of the new Chirajara bridge and other environmental tasks are still pending, the project's environmental license will remain valid and will be monitored and controlled until the beneficiary completes all the construction activities and environmental tasks that continue to be carried out to date. Additionally, and from the point of view of the supervision of construction works and in accordance with the line of research in one of the branches of the supervision, the environmental supervision, in this work the environmental monitoring methodology that is established by law and which serves not only for environmental authorities but also for all the supervisors of works that at some point must carry out environmental monitoring, this methodology is fully applied and is the one indicated in the "manual de seguimiento ambiental de proyectos: criterios y procedimientos” from the Ministerio del Medio Ambiente.Ítem Estrategia para el seguimiento y control administrativo de la interventoría de obra, en la fase de ejecución, de proyecto tipo: terminal de pasajeros de la plataforma del aeropuerto El Embrujo de la isla de Providencia, en el archipiélago de San Andrés y Providencia y Santa Catalina.Hernández García, Estefani Cristina; Novoa Walles, Juan Fernando; Mena Serna, MiltonTaking unto account that the supervision si un charge of controlling and demanding compliance with the contractual deadlines, the scope of the project and budget, this thesis will be developed.

This thesis focuses on proposing a functional tool for auditing entities based on the earned value methodology that allows them to improve their work of verifying and supporting administrative aspects, which exposes the criteria of the physical progress of the project and indices, generating early warnings that speed up decision-making and provide a different tool.Ítem Metodología para el control y seguimiento de la interventoría técnica en la fase de recibo de zonas comunes para proyectos tipo VIS construidos en el municipio de Tocancipá en el Departamento de CundinamarcaFalla Páez, Claudia Marcela; Gantiva Quintero, Cristhian David; Mena Serna, MiltonThe present degree work is focused on the elaboration of a methodology for the control and monitoring of the technical inspection in the work receipt phase of common areas for VIS-type projects built in the municipality of Tocancipá in the department of Cundinamarca. This proposal arises from the cases mentioned in the bibliographical references and the little experience that is had for the receipt of common goods since this inspection is not so common in the field of construction and the co-owners have presented dissatisfaction at the moment in that the construction company delivers the areas incompletely and with poor quality. Generally, the shortcomings that generate dissatisfaction in the co-owners at the time of receiving the common areas are leaks, green areas in poor condition or damage due to maintenance, sometimes lack of enclosures, lack of fire extinguishers, incomplete or absent technical documents and manuals, lack of railings, etc., among others that may vary depending on the project and its characteristics. The methodology proposed by this degree work is based on the need to implement an instruction that contemplates the receipt and operation of the common goods of a specific case for the project VIS CONJUNTO RESIDENCIAL CAMINOS DE SIE 1. Likewise, to have clarity of the documentation that support and guarantee the quality of the construction that facilitates the operation and maintenance of the common areas for the co-owner. The use of the methodology would help the auditor to more fully develop his work in the control of designs, of the construction work, also monitor and develop technical aspects, compliance with regulatory provisions in the construction work phase. receipt of the areas of the horizontal property.Ítem Propuesta metodológica para seguimiento y control de interventoría técnica en fase de ejecución de escenarios deportivos en estructura con pórticos de concreto reforzado y cubierta metálica en la ciudad de Neiva – HuilaMoreno Chaparro, María Alejandra; Perdomo Polania, Faiver Eduardo; Mena Serna, MiltonThe purpose of this work is to develop a methodology for the control and monitoring of technical auditing in the execution phase for projects such as a covered sports arena built in reinforced concrete in the city of Neiva, the development of the document leads to determine the guidelines for auditing public works with which control processes that lead to a proper completion of the structures avoiding detriments to the treasury are established, In addition, the territorial entities consolidate support figures that lead to linking personnel with the skills and knowledge to monitor the works, taking as a reference base technical and regulatory guidelines for the control of the works. The inclusion of auditing processes allows mitigating reprocesses and inconsistencies in the work that are characteristic of public order projects and generating greater confidence in those involved as well as third parties, visualizing opportunities for improvement in the medium term, avoiding the growth of white elephants, at the moment in which control is exercised over time, materials, suppliers, costs, infrastructure, among other mechanisms that are causal to bring the work to a successful conclusion.Ítem Metodología para la interventoría administrativa en fase de ejecución de contratos de intervención vial; caso de estudio: tramo comprendido en la Av. Villavicencio entre Av. Tintal y Av. 1° de Mayo en la ciudad de Bogotá D.C.Benítez Gutiérrez, Yurany Andrea; Herrera Vargas, Maria Fernanda; Villarreal García, Cristian David; Mena Serna, MiltonThrough the execution of this project, a methodological proposal was addressed, the product of which consisted of an instruction that serves as a guide for the development of administrative supervision in the execution phase of road intervention contracts, for which the section included in Av. Villavicencio between Av. Tintal and Av. 1° de Mayo in the city of Bogotá D.C., focusing on the causes that generate delays in the projects and the contractual modifications that these cause. For this, a documentary review of the other documents and reports of the project corresponding to the case study was carried out, where the justifications for the work and auditing were identified through which the contractual modifications were given. In the same way, surveys were carried out on engineering professionals and related careers, with the objective of analyzing the different causes that generate delays in the works, and thus, in this way, the criteria were established by means of which they are mitigated and / or reduced. delays in road intervention works.Ítem Elaboración de guía técnica para el control en los procesos constructivos de bodegas comercialesEspitia Moreno, Yorely Marcela; Parra Ardila, Luis Augusto; Roa Ruiz, Johan Smith; Mena Serna, MiltonThe objective of this endeavor is to encompass the oversight of construction through the utilization of the BIM methodology, with the aim of identifying novel technical management and control mechanisms that can be implemented in medium-sized commercial warehouse projects. These tools have been specifically devised to optimize the efficiency in coordinating all construction processes, in conjunction with the supervisor and builder, while keeping the contractor's advantage at the forefront. As a result of this project's progression, an Excel matrix outlining the responsibilities of the contractor, technical supervision, and cost authorizer was formulated to facilitate collaboration. Furthermore, a comprehensive compendium of activities that lead to construction reprocesses was compiled, with each activity ranked according to its impact, ranging from the most significant to the least. Additionally, an application guide for the BIM methodology was developed to effectively control Revit models.Ítem Metodología para la supervisión técnica en la inspección de elementos no estructurales en edificaciones de uso residencial de más de 2000 m² en la ciudad de Bogotá.Pachón Soler, Jhoana Lorena; Chisco Solano, Diana Mabel; Ávila Cárdenas, Viviana Marcela; Mena Serna, MiltonIt has been shown not only in Colombia but in many places in the world that earthquakes or telluric movements cause major disasters; and the field of construction is not exempt from being affected by this natural condition, buildings according to their design may or may not resist these movements; According to the antecedents and results after an earthquake, non-structural elements are the main causes of damage to human life. It is for this reason that the construction of buildings has seen the need to evolve to safeguard human life; with buildings that are safer every day. Where everyone who participates in the process is aware of the importance and responsibility acquired. Understand that each component of a building is equally important to the previous one, that it must be designed as a whole, that a building is not only the main structure, but that the non-structural elements are part of that set, which must also be subject to constant verification. Here a verification tool is provided supported by the guidelines and requirements of the 2010 Earthquake Resistant Standard, which is the current regulations in Colombia for the technical supervision of buildings.
