30+ years in commercial construction, including 15 years as a superintendent managing projects from preconstruction through execution. I help contractors produce accurate, buildable estimates that hold up in the field — not just spreadsheets of numbers. Many of my recent projects involve electrical takeoffs and bid support, including: • lighting and device counts • panelboards and distribution equipment • feeders and branch circuits • electrical equipment connections CORE ESTIMATING SERVICES • Electrical takeoffs (commercial projects) • Quantity takeoffs (architectural / structural) • Bluebeam plan takeoffs (color-coded, organized) • Bid leveling and scope comparison • Microsoft Project CPM scheduling • Procore workflow alignment FIELD-DRIVEN ESTIMATING With 30+ years in construction leadership, my estimates account for real execution conditions, including: • trade coordination and sequencing • retrofit and tie-in conditions • hidden scope gaps in drawings and specs • constructability constraints • code-driven requirements and special inspections DELIVERABLES • Bluebeam markups with highlighted takeoffs • Excel quantity takeoffs (CSI organized) • scope clarifications and assumptions • optional CPM schedules If you need a bid that holds up in the field — not just on paper — I can help.

Not all Manual JSD and Energy Code services are created equal! Saving a few dollars now could cost you a lot later on. That's why you should choose me for all of your energy compliance or HVAC design needs. If you are a mechanical engineer doing HVAC projects, let me do the tedious code compliance documentation for you! I use Wrightsoft to produce Manual J reports based on your plans, either with specified insulation levels or code minimums, as well as Manual S reports based on your selected equipment line (or provide recommendations) and Manual D reports based on your layout or I can provide a layout from scratch. My reports are currently being used by engineers in California, Colorado, Maryland and Florida. I can also provide Manual T spreadsheets for correct register selection and placement to optimize airflow and mixing. For all reports I offer PDF page placement, putting the reports on your provided plan page template or my own page to match your plan size. I also offer a full layout overlay on your floor plan and/or structural plan for coordination and bidding. In addition, I provide Energy Code Compliance in all 50 states: -Title 24 in California, using EnergyPro software. Any kind of residential or non-res project. -Washington state energy forms, res and non-res -Oregon energy reports -Florida R405 reports using EnergyGuage or Wrightsoft -ResCheck for anywhere else in the country -Comcheck for anywhere else in the country No matter where you are, you can have confidence that I can handle your construction project. Even more important, I take the time to weigh all the options and ensure that you get the best results possible. The choices made in the energy calculations can have expensive consequences later. I have the experience necessary to ensure your projects’ compliance, not "by any means necessary", but "by the best means possible." This will save you money throughout your project. In addition to my experience in the energy and HVAC field, I have 20 years of experience as a carpenter, including many years as a contractor. This gives me a unique edge, in that I fully understand how houses are built and know them from the ground up. What does this mean for you? A smooth ride at the building department, and no nasty surprises down the road! So, make the right choice. Contact me regarding your upcoming project! You won't regret it.

Using Helioscope, EnergyToolbase, and real EPC cost assumptions, I provide fast feasibility layouts, production models, and financial analysis for commercial and utility-scale solar projects. I’m a commercial solar EPC estimator with 10 years of renewable energy experience focused on PV/BESS system design, electrical takeoffs, cost modeling, and preconstruction planning. I’ve estimated over 170 MW with $64M awarded, supporting developers, EPCs, and contractors with accurate pricing and clear design concepts. My core skills include Helioscope layout design, EnergyToolbase modeling, Accubid estimating, value engineering, and proposal development. I enjoy solving complex design and cost challenges, optimizing system layouts, and helping teams bid confidently.

I take apparel concepts from sketch to sample — patterns drafted by hand, tech packs built for production, and physical prototypes sewn before anything goes to a factory. I’m the founder of SÔZ Studios, a menswear brand I built from scratch — teaching myself to sew, draft patterns, and develop garments end to end. I also run SÔZ Studios Atelier, a product development consultancy for apparel founders and brands who need a technical partner, not just a freelancer. What I deliver: — Technical sketches (front, back, side) — Complete tech packs with BOM, construction details, and spec sheets — Flat pattern development — Hand-sewn prototypes for fit validation — Production guidance and factory-ready handoff I’m based in Los Angeles with an active factory relationship for production grading and runs. I work with founders at the earliest stage and brands refining existing styles — fixed-price engagements welcome. If you have a concept and need someone who can actually build it, let’s talk.
