Yahir Castellanos

Proficient in marking and chipping piles to specified elevations, and pouring seal slabs with precision. Skilled in setting beds of boards and using string lines to establish accurate center points. Experienced in reading blueprints and executing detailed layout work for foundations, forms, and structures.

Capable of setting and fabricating forms, creating grout pockets and templates, and transferring layouts from corners using clamps and layout tools. After foundation pours, responsible for setting layouts for pedestals, installing forms, and aligning them with turnbuckles to ensure straight and level sides.

On form tops, accurately locate and mark centers to align templates, set anchor bolts, and ensure squareness using rise-and-run calculations and a digital calculator. Plumb bolts with torpedo levels and secure them using tie wire. Prior to pours, verify all turnbuckles are properly tightened and bolts are stabilized to prevent shifting.

Demonstrates a strong work ethic, precision in structural setup, and a solid understanding of concrete forming and layout practices—ready to contribute to high-quality construction projects.

Experienced in reading and interpreting blueprints to perform accurate layout work and material preparation. Skilled in cutting materials and templates to spec, shooting elevations, and marking TOC (top of concrete) on forms for precise concrete placement. Proficient in setting and fabricating forms, building grout pockets, and creating custom templates as needed.

Capable of aligning anchor bolts using string lines, rise-and-run measurements, and various leveling tools to ensure proper alignment and squareness. Hands-on experience with pouring seal slabs, foundations, pedestals, and other concrete structures. Also performed chipping and cutting of piles to meet structural and elevation requirements.

Well-versed in operating a wide range of tools including hammer drills, impact drivers, skill saws, jigsaws, reciprocating saws, grinders, adjustable drills, torches, and more. Known for precision, reliability, and a strong understanding of both structural requirements and finish work.

Skilled in building and setting boards for concrete work, with the ability to accurately interpret all types of blueprints. Proficient in shooting dirt elevations and preparing sites for seal slabs. Experienced in layout work, including setting forms using turnbuckles, clamps, speed bolts, and shoes. Accurately cut templates according to plans and transferred layouts from string lines to pedestals using torpedo levels.

Worked with a variety of form systems including Alumna, Emiba, H-forms, Deco forms, and fabricated custom forms when required. Used redwood and traditional wood forms for paving, consistently marking the top of concrete for proper finish levels. Constructed complex structures such as wing walls and table tops. Skilled in bushing pedestals and grout pockets using chipping hammers and bushing bits to meet spec.

Demonstrates attention to detail, reliability, and a strong work ethic across all phases of concrete foundation work.

• Constructed concrete footers and pedestals for pipe racks, established grade elevations for seal slabs, and installed grade stakes. Interpreted blueprints and assisted with layout work for foundations, pedestals, surge vessels, compressors, cold boxes, and more. Installed and adjusted forms using turnbuckles, clamps, and spacers, and also fabricated custom forms as needed. Shot elevations and aligned anchor bolts with precision to ensure proper bolt plumb. Participated in tank construction by setting forms, placing bolts and templates, and bush-hammering or patching small areas in accordance with design specifications. Performed chipping, cutting, and adjustments around compressors, and modified trench depths to correct elevation discrepancies.
