The construction sector in Colombia is a fundamental pillar of national economic growth, as it generates employment and territorial development. 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.

Road concession contracts under the Public-Private Partnership (PPP) model are a great success both nationally and internationally. This success is due to the fact that a large part of the risks are transferred from the public to the private sector, which considerably reduces the expenditure of the treasury. However, in contrast, poor identification, allocation and distribution of these risks can lead to claims arising during the execution of the contract. These claims are generally due to economic imbalances that the parties must reconcile. One of the tools for this purpose is unpredictability, since these imbalances are often caused by unforeseen situations that arise during the execution of the contract. The financial controller has a vital role since, having knowledge of the established risks, the contractual obligations, the possible alerts and the principles of unforeseeability, he can seek agreements in anticipation of onerous legal proceedings.

Lara Hernández, Jesús Antonio; Mena, Milton
Each 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.
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 anclados
Bravo Guzmán, Cristian Felipe; Cordón Barrera, Osmar Adrián; Forero Buitrago, Diego Fernando; Mena Serna, Milton
Geotechnical 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.

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.

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.
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 Meta
Castellanos Echeverri, Rodolfo Steven; Castro Rodríguez, Fidel Ricardo; Sánchez, María Alexandra; Mena Serna, Milton
It 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.
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, Milton
This 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.
