Extraction","sector":"23","jobZone":2,"jobZoneInferred":false},"framework":{"version":"v.26.05","description":"","contextCovered":"This framework covers residential and commercial stonemason practice from entry-level site assistance through executive-level project leadership, including stone cutting and setting, mortar work, alignment, joint finishing, restoration, and business operations.","levels":{"emerging":{"label":"Emerging","statements":["Plumb bob and level — identify and handle under direct supervision to check basic vertical alignment on a masonry job site.","Straight edge and staked lines — follow pre-set layout instructions to assist in marking wall patterns or foundation outlines on level ground.","Cut stone and marble pieces — operate hand tools under close supervision to perform simple trimming tasks in a workshop or field setting.","Mortar mix — measure and combine materials according to a prescribed recipe under a journeyman's guidance on a construction site.","Pre-cut stone units — place and position in a designated layout pattern under direct supervision during new construction work.","Excess mortar and grout — remove from stone or marble surfaces using sponge, brush, and water following cleanup procedures on a job site.","Basic joint-filling tasks — assist a lead mason in packing mortar between stones using a trowel under step-by-step direction.","Prefabricated masonry units — carry, stage, and assist in installing components as directed by an experienced stonemason on a residential project.","Safety protocols and personal protective equipment — recognize and apply when handling power saws and stone-cutting equipment in a training environment.","Work site materials and hand tools — identify, organize, and maintain in proper condition at the start and end of each work shift."]},"developing":{"label":"Developing","statements":["Plumb bob, gauge line, and level — use independently to verify and correct vertical and horizontal alignment of stone walls on standard residential projects.","Wall layout and foundation patterns — read blueprints and use a straight edge or rule to lay out stone courses with minimal oversight on routine assignments.","Stone and marble setting — place units according to specified layout patterns, adjusting fit and spacing on moderately complex commercial or residential installations.","Mortar joints — finish and smooth between stones using a tuck pointer to produce a clean, consistent appearance on standard masonry surfaces.","Power saws and cutting equipment — shape, face, and trim stone or marble to required dimensions, adapting technique to varying stone types in a field setting.","Mortar and grout — mix to correct consistency and spread evenly on slabs or foundations, pacing output to match the installation workflow.","Prefabricated masonry units — construct and install following manufacturer specifications and project drawings with limited supervisory review.","Surface cleaning — select appropriate cleaning agents including acid where required and apply safely to remove staining or excess grout from finished stone work.","Time and task sequencing — manage personal workload across multiple stages of a masonry project to meet daily production targets without prompting.","Arithmetic and measurement — apply job-site mathematics to calculate material quantities, cut dimensions, and mortar volumes for routine stone installations."]},"proficient":{"label":"Proficient","statements":["Complex alignment systems — independently set and verify vertical and horizontal alignment across large or irregular structures using plumb bob, gauge line, and optical level.","Custom wall and foundation layouts — interpret detailed architectural drawings and translate them into precise staked-line patterns for ornate or non-standard stone installations.","Decorative and structural stonework — set stone and marble in demanding patterns, including curved, angled, or multi-material assemblies, without supervisory guidance.","Joint finishing and tuck pointing — execute consistently high-quality mortar joints across varied joint widths and profiles on historic restoration and premium commercial projects.","Advanced stone cutting and shaping — operate power saws and hand-cutting equipment to produce precise custom profiles, curves, and surface textures on specialty stone.","Grout and mortar formulation — select mix ratios and admixtures appropriate to exposure conditions and stone type, adjusting on-site based on temperature and substrate variables.","Problem diagnosis on masonry structures — identify causes of cracking, settling, or moisture infiltration and determine corrective repair strategies on active construction or restoration sites.","Prefabricated and custom masonry integration — plan and execute combined installations of prefabricated units and field-cut stone to meet complex design and structural requirements.","Project drawings and specifications — read and critically interpret full construction document sets including CAD drawings, ensuring stone work meets design intent and building codes.","Quality control inspections — evaluate finished stone surfaces, joint work, and alignment tolerances against project specifications, identifying and correcting deficiencies before project handoff."]},"advanced":{"label":"Advanced","statements":["Project execution standards — establish masonry quality benchmarks and inspection criteria for entire job sites, ensuring all crew members adhere to alignment, finish, and safety requirements.","Crew training and skill development — mentor emerging and developing stonemasons in stone-cutting, setting, and joint-finishing techniques across live residential and commercial projects.","Scope and sequencing planning — develop detailed work plans for large-scale masonry projects, coordinating material delivery, crew scheduling, and subcontractor sequencing to meet milestones.","Complex problem resolution — diagnose and resolve non-routine structural or aesthetic failures in stone installations, applying advanced judgment to historic, architectural, or high-profile projects.","Client and design team consultation — communicate technical masonry requirements, material limitations, and value-engineering options to architects, engineers, and clients throughout project delivery.","Estimating and cost management — prepare comprehensive material and labor estimates using project management and spreadsheet software, controlling budget variances across multiple concurrent jobs.","CAD and specification review — evaluate architectural CAD drawings and stone specifications for constructability, flagging design conflicts and recommending solutions before work commences.","Safety and compliance leadership — develop and enforce site-specific safety protocols for power equipment, heavy stone handling, and hazardous cleaning agents across an entire masonry operation.","Organizational best-practice development — author standard operating procedures for mortar mixing, stone cutting, and installation sequences, institutionalizing quality across a masonry contracting firm.","Strategic workforce and business development — identify skill gaps, guide hiring decisions, and build vendor relationships that position a masonry business for sustained growth in the construction market."]}}},"sources":{"onet":"v30.2 (CC BY
