DEVELOPMENT ## **7.1. Generalities** Prior to the start of the Topography works, the necessary permits must be generated to carry out the required topographic controls in accordance with the Client's regulations, compliance with the current legislation (Entry to Areas, Work Permits, 5-Minute Talk, ARTP, applicable PSGCC and Use of PPE). According to the stages of work indicated by the Construction program, the following will be performed: execute, control and verify the topography works according to the plans, reference points (PRs) and technical specifications supplied by the Client and necessary to ensure the conformity in the performance of Topographic works. If the Reference Points provided by the client are insufficient for the performance of construction works or for As-Built documentation, additional stations will be established. Additional topography stations will only be established as temporary PRs, serving exclusively to the particular work of topography. If there are stations that are destroyed or missing, they must be re-established as soon as possible. In carrying out the activities, precision equipment such as total station, GPS and levels will be used (certified in their calibration), qualified personnel to comply with the works and times assigned to the activity. ## **7.2. Control and Verification of Topographic Equipment** In order to ensure the quality of the controls and topographic surveys, the surveyor must verify the operating conditions of the measuring equipment at the beginning of each shift, in accordance with the technical data sheet provided by the manufacturer. The maximum error allowed will be the one declared in the equipment manual. In the event that the data obtained in the field exceed the error described in the manual, a second round of measurements must be made to ensure the data. In the event that the error persists, the instrument cannot be used and must be sent to be calibrated in specialized laboratories. It will be the surveyor's responsibility, to verify periodically the calibration certificates of the measurement equipment through the Check List of Topographic Instruments, in turn it is the responsibility of the person in charge of quality to verify that this process is carried out and is duly certified. The control of this equipment is carried out in the list of EIME, and its control frequency is 12 months after its calibration, it is responsible for keeping a copy of the certificate for your consultation. Calibrations must be performed by a laboratory recognized by the INN. ## **7.3. Check or verification of the proper functioning of topographic equipment in the field** * **Total Station:** It is an optical topography instrument that combines the functions of angular measurements, electronic distance measurements (EDM), the integrated data capture functions and coordinate geometry (COGO) in a single topographic instrument. * **Level:** It is optical topography equipment that allows the establishment or determination of vertical differences and/or elevations of topographic reference points. ## **7.4. Topographic Controls to the Construction of Works** Topographic controls must be performed on all the works that are included in the scope of the contract: * Platforms. * Duct. * Civil Works. * Structures and Mechanical Equipment. The topographic controls of structures and mechanical equipment will be performed with the equipment, which will be embedded in the concrete. ## **7.5. Tolerances** The tolerances adopted will be those established in the Project documentation for each Contract and will be indicated in the Topography protocols. ## **7.6. Protocols** Reference protocols will be prepared in accordance with what can be measured as a function of the stages of the project. The representation of the protocols is as follows: * Earth line survey (cutting and filling are included). * Trenching. * Bottom trench longitudinal profile. * Sand bed longitudinal profile. * Pipe lowering (As-Built). * Pre-filling, filling. * Final earth line shaping. The protocols will be prepared in the Bonatti technical office and, once their preparation is complete, they will be sent to the client for their signature. The original document will remain in the Document Control Office. The valid document will be the endorsement of the conformities by the parties (client and contractor) in the field work log in order to streamline the work. The timelines for the submission of protocols will be agreed upon between the parties involved. During the construction phase, the protocol is considered a contractual document. Upon completion of a work stage, of any specialty, the protocol must be signed and have the respective approvals. You cannot continue with the next construction stage without verification and taking the formal knowledge of the protocol in conjunction with the Topography defined by the Client. Once the protocol is signed, the Surveyor must make a copy and deliver it to the Quality area for its respective file and the return of the original. If the work shows deviations with respect to plans or EETT, the protocol will not be signed and will be assessed in conjunction with Quality, the notification of a Non-Conformity, in order to have evidence and control of the deviations produced during the work process. Any deviation detected by the Topography Area, must be communicated immediately to the Quality area, who transmits to the Client. ## **7.7. Specific Topography Activities** * **Laying out of Stockyard Areas for Pipes and Installations, site re-staking** The topographic squad will perform the laying out, marking of levels and all the activities related to the topography of the pipe stockyard areas and temporary use areas. The topography activities in the stockyard areas and temporary areas will be carried out using the following steps: * Mark the perimeter limits to be cleared with wooden or steel stakes, with tape or yellow paint. * Obtain the terrain levels, for the required leveling. * Laying out of roads and berms. * All the information and data obtained during the development of the activities described in this item will be recorded in the plans and drawings for the project's engineering. * **Laying out of the Track** The right of way (RoW) laying out works will be carried out by the topographic squad. The topographic squad will mark the limits of the strip with wooden or steel stakes, which must be identified with tape or orange paint. The stakes for marking the layout and delimitation of the track will be placed on both sides of the RoW and every 100 meters; the chainage of the duct must be marked on each stake. The topographic squad will mark the changes in direction of the RoW and each change in direction must be clearly marked. The topographic squad must place a control point (tab) every kilometer with reference to the duct's chainage. * **Duct Trench Laying Out** The duct trench laying out/re-stating will be performed by the topographic squad, marking the duct axis every 50 meters, and at the points where it is necessary due to the terrain relief, re-stating can be made at a shorter distance to keep the reference stakes of the duct axis in view, the marking will be with a red ribbon or paint. In this case, the surveyors will descend into the trench through the accesses defined for these areas, in accordance with the Client's standards, for their topographic control. For this, they will be assisted by ladders at intermediate points, which must be anchored at their top and bottom; they must also have a fall protection system. Access ramps at the ends of the trench are also considered. The ponchos that are placed for the laying out/re-stating of the trench axis, must have the cutting depth to the bottom of the trench and the chainage or Kilometer Progression (KP) written. * **Laying out of Crossovers** The laying out/re-stating of the project's crossovers will be performed by the topographic squad, marking the axis of the duct at each end of the crossover, placing the number of stakes and points as the person in charge of the squad considers necessary for guidance and reference of each crossover. All the wooden stakes that are placed to identify the limits of the RoW, will be identified with orange tape or will be painted in the top with orange aerosol paint. On those stakes that are placed for the laying out/re-stating of crossovers, they must have the chainage or KP written. Typical crossovers are the following: * Roads. * Highways. * Railway lines. * Rivers, streams and runoff waters. * Canals/Drains. * Buried existing ducts. * Overhead installations (transmission lines and any other infrastructure). In the case of ravines, the following information must be taken: * Laying out the axis in coincidence with the crossover/crossing of the ravine, re-stating at least: upper or lower edges, upper or lower edges, riverbed and lowest point of the channel. * In the event that the topography is very hilly, take data at the most representative points without disregarding the above. * If the RoW crosses uphill or downhill, a grade/percentage of the same must be placed every 50 meters. In the case of crossing power lines, the following data must be taken: * Location of towers or poles * Angle or direction of the crossover * Height of the catenary in coincidence with the axis of the planned pipe * Crossing of existing operational/inoperational lines. * **Laying out of Additional Areas** The laying out/re-stating of additional areas for special points or project crossovers, will be performed by the topographic squad, placing stakes at the vertices with yellow tape or paint to identify the additional area. The topographic squad must perform the laying out based on the drawings and plans specific to each additional area. The drawings and plans must be approved for construction The topographic squad must obtain the data and accurate coordinates of the additional areas, with the aim of being able to verify that only the area assigned as additional has been used in the specific authorized points. * **Laying out of Vent Valves** The activities of laying out/re-stating of vent valve areas are carried out by the topographic squad of the project, they must perform the work based on the project's engineering plans / drawings and the applicable documents. The engineering drawings and plans for the construction of the vent valves that the topographic squad will use for the laying out of the premises must be approved for construction and they must be the latest approved revision of the documents. The polygonal of the terrain of the vent valves must be marked in such a way that it is visually identifiable to facilitate the location. The polygonal of the terrain where the vent valve chambers are to be built, must be delimited with boundary markers that allow for the prompt reference and verification of the coordinates of the property of the valves. During the laying out/re-stating activities of the vent valve chambers, the chainage or KP corresponding to the location of the valve must be written on the stakes, the wooden or steel stakes that are used for this laying out must be identified with tape or red paint. In the area / polygon of the vent valve chambers, the duct's axis or center line must be laid out and marked with stakes, these stakes must be marked with a red ribbon or paint at the top. In the area of each vent valve chamber, a bench type boundary marker must be placed to have a reference level for the development of the work of building the civil, electrical and mechanical work. The activities of control and topographic surveying for laying out / restating of the vent valve chambers will be recorded in the registration format of Annex A of the present procedure "Protocol for Topographic Surveying in Diverse Areas". * **Laying out and Identification of Existing Overhead and Underground Infrastructure** The existing infrastructures that have interference with the duct's trajectory of the project must be identified and their trajectory or their RoW limits marked, marking their delimitations and interferences. The laying out and identification of these infrastructures will be carried out by the topographic squad, who must place wooden stakes with blue tape or paint, in addition they must place a board where they will indicate the chainage (KP) of the project's duct and the one of The topographic squad will be in charge of defining the area's As-Built topography, which should be based on the project's topographic system. Once the pipe is in its final position and before its backfill, if applicable, the surveyors will collect information on how the lines were finally built. This information will include the following: * The elevation or elevation TOP of the pipe, this at each of the points required to be surveyed with topography during the preparation of As-Built topography (welds, curve centers, etc.). * Final changes in the pipe thickness position. * Tie-in points to other facilities. * Cathodic protection * Inspection cameras. To proceed with the execution of As-Built, the codification established in the Data Dictionary must be met. * **Backfill and Recomposition** After backfilling, the topographic team will assist in final recomposition, indicating the accurate position of the installed pipe. An inventory of all installed items will also be carried out. ## **8. QUALITY** The Quality inspector in the field, will be in charge of verifying the correct execution of the activities, for example: * Ensure that the equipment and instruments are properly calibrated and have a valid certificate. * Review of the protocols generated by Topography. # **9.
