The diagrams should be created in vector line art format, without the use of AI. Requirements: - Diagrams should focus on water pollution aspects - Must be in vector line art style - No AI-generated content Ideal Skills and Experience: - Proficiency in vector graphics software (e.g., Adobe Illustrator, CorelDRAW) - Strong understanding of environmental engineering concepts - Experience in creating technical and scientific illustrations - Attention to detail and accuracy Please provide samples of previous work related to scientific or technical diagrams.
I have a residential project that is already under construction and the building department has requested a REScheck demonstrating full compliance with IECC 2021. All architectural and envelope details are available; what I need is the completed energy compliance report, ready to submit. Please use the latest REScheck software, enter the project data, and run it against the 2021 code. Deliverables (PDF and digital file): • Signed REScheck compliance report meeting IECC 2021 • The native .rck file so future edits remain possible • A short note outlining any insulation, window, or envelope assumptions used to achieve compliance Once the report passes with no outstanding corrections, the job is done.
I need my current river model in HEC-RAS refined so it reliably supports flood management decisions. All geometric files, cross-sections, hydrologic boundary conditions, survey points, and historical high-water marks are already organised and ready for import, so you will be working with a complete and detailed data set rather than starting from scratch. The assignment is to adjust roughness coefficients, bank stations, ineffective flow areas, and any other relevant parameters until the simulated water-surface elevations match observed events within an acceptable tolerance. Once the model is behaving consistently across a range of flows, generate clear channel and floodplain delineations that I can overlay in GIS for downstream engineering and permitting work. Flood maps or velocity grids...
I’m ready to move forward with a two-container residence—two 40 ft shipping containers joined into a single-story, 6 feet between container, 2 feet above the ground, open-floor-plan home with 2 bedrooms —on my 2.5-acre parcel in Paulden, AZ. Because the lot sits in a mapped flood zone, I need a permit package that satisfies Yavapai County building and flood-plain regulations. Here’s what I need from you: • Site plan and layout that clearly positions the containers, parking, setbacks, and required drainage features on the property. • Detailed architectural drawings suitable for county submittal, showing foundation, structural tie-ins between the containers, roof framing, elevations, and any flood-proofing details. • Structural engineering c...
I am ready to move ahead with the full design-and-build of a new PVC water main serving 20 residential plots on our development site off Bellswood Lane. The route runs entirely through soft soil, and each plot will need variable pressure so that owners can install everything from standard taps to high-flow garden systems without retrofitting pumps later. Here is what I need from you: • Detailed hydraulic sizing and layout drawings (AutoCAD / Civil 3D or similar) showing pipe runs, valves, hydrants, and individual plot branches. • Pressure-zone modelling (EPANET or equivalent) that demonstrates reliable variable pressure across all 20 plots when tied into the municipal feed. • Trench, bedding, and backfill specifications tailored to our soft-soil conditions, including a...
I’m ready to move a commercial site in Alpharetta, GA through the Land Disturbance Permit process and need a full drawing package prepared.
