CAD/BIM Draftsperson & Technician — Structural, Geotechnical, Hydraulic & Civil Works (Hourly)

ABOUT US We are a Chilean engineering firm specializing in structural, geotechnical, hydraulic and hydrogeological studies. More than 530 projects delivered across 13 regions of Chile, with a senior team holding over 185 years of combined experience. We take part in mining, energy, industrial, infrastructure and real-estate projects, from conceptual engineering through construction. We hold registrations with MOP, MINVU, INN and ChileCompra, and operate under ISO 9001, 14001 and 45001 standards. We are expanding our network of collaborating drafters to support the document production of our projects, under an hourly contract through Upwork. WHAT THIS ROLE IS Technical documentation. Our engineers define the design, criteria and dimensions; you produce the drawings, sheets and models that communicate it. You will not be asked to make calculation or structural-design decisions. You will be asked to draw with precision, follow standards, keep consistency across sheets, and deliver documentation ready to be issued. This is a role of rigor and craft. We value someone who catches that one dimension does not match another before the reviewer does. HOW WE WORK (read before applying) - The contract is hourly within Upwork, with time logged through the platform's Time Tracker. We do not work outside Upwork. - Before each assignment we agree in writing on: scope, number of sheets, level of detail, delivery format and an estimated hour cap. If the work exceeds the estimate, it is discussed and approved before continuing. - All communication, sharing of background information and delivery of results happens through the platform's channels. - We work with our own standards: templates, title blocks, layers, text and dimension styles, blocks and symbology. We provide the complete package at the start and expect you to follow it strictly. - We begin with a first paid assignment of 5 to 8 hours, paid from the very first hour. We do not request free tests. - If the result is good, we move to a continuous flow of assignments with stable weekly hours. SCOPE OF ASSIGNMENTS Depending on your specialty, you will take part in one or more of these lines: 1. REINFORCED CONCRETE STRUCTURES - Structural plans, elevations, sections and details. - Rebar and reinforcement detailing drawings. - Foundation, footing, slab, beam, wall and column details. - Rebar schedules, steel quantities and bar lists. - Joint, anchor, penetration and insert details. 2. STEEL STRUCTURES - Erection drawings and shop drawings. - Bolted and welded connection details. - Lists of profiles, bolts, plates and elements. - Piece detailing and erection marks. - Industrial structures: sheds, pipe racks, platforms, stairs, walkways, transfer towers. 3.

UNDERGROUND WORKS - Typical sections of tunnels and galleries. - Support details: rock bolts, mesh, shotcrete, steel ribs. - Precast segment detailing. - Access shafts, diaphragm walls and access structures. - Underground stations and construction sequences. 8. SURVEYING AND SITE LOCATION - Topographic survey drawings and contour lines. - Site-location and general-location drawings. - Quantity sheets and surface comparisons. - Setting-out drawings with coordinates and staking. 9. BIM AND COORDINATION - Structural and civil-works modeling in Revit. - Multidisciplinary coordination and clash detection in Navisworks. - Extraction of drawings, quantity schedules and takeoffs from the model. - As-built modeling from existing information. - Maintaining naming, family and level-of-detail standards. 10. DOCUMENT PRODUCTION AND STANDARDIZATION - Sheets and technical figures for reports and memoranda. - Explanatory schemes, diagrams and technical tables. - Assembly and organization of complete drawing sets. - Drawing updates by revision, version control and revision clouds. - As-built drawings from field markups. - Cleanup and standardization of legacy files. STAGES WE WORK IN Conceptual, basic, detailed engineering (IFC drawings) and as-built. MANDATORY REQUIREMENTS - Technical or professional training in technical drawing, engineering projects, civil construction, architecture or equivalent. - At least 3 years of experience producing engineering drawings for real, built projects. - Advanced command of AutoCAD, including management of layers, blocks, external references, scales, layouts and presentations. - Command of at least one additional tool according to your specialty: - Civil and road works: Civil 3D, Bentley OpenRoads, MDT or Carlson. - BIM: Revit and Navisworks. - Steel structures: Tekla Structures or Advance Steel. - Documentation and review: Bluebeam Revu or equivalent. - Ability to work on external templates and standards without modifying them. - Rigor in consistency: dimensions, scales, levels, naming and correspondence between sheets. - Fluent written Spanish (this is a firm requirement; our engineers and documentation work in Spanish). - Minimum availability of 15 hours per week and response within 24 business hours. - Equipment capable of working with heavy models and files. - Willingness to work with Upwork time tracking active. DESIRABLE - Experience in industrial or mining projects. - Experience in rebar and reinforcement detailing drawings. - Experience in steel-structure shop drawings. - Knowledge of Chilean drawing-presentation standards and MOP formats. - Command of BIM naming standards and levels of development. - Automation with LISP, Dynamo, scripts or macros. - Experience with version control and document-review workflows. - Basic notions of structures, geotechnics or hydraulics that let you understand what you draw. - Technical reading English. MODE AND BUDGET - 100% remote, hourly contract on Upwork. - We prefer time-zone overlap with Chile (UTC-3/-4), but we are flexible if communication is fluid. - Hourly rate according to proven experience. State your real rate. HOW TO APPLY We discard generic proposals. In your application include: 1. Your main specialty among the ten lines listed above, and how many years you have been producing that type of drawing. 2. Your software and real level of command in each, with years of use. 3. How many sheets you produce on average per workday and of what type. 4. How you verify the consistency of a drawing set before delivering it. 5.
