Professional Structural Engineering
Services — PA · NY · DE · TX

New construction projects — whether a single-family home, a commercial building, or an industrial facility — require a complete structural engineering design from the ground up. At NEC Solutions LLC, we provide the full structural package that your architect's plans need to become a buildable, code-compliant reality.

We design the structural system — framing, beams, columns, connections, and foundations — based on the architectural layout, site conditions, and applicable building codes. Our drawings are clear enough for any experienced contractor to build from, and detailed enough to satisfy any building department plan reviewer.

• Structural framing plans (wood, steel, concrete)
• Beam and column schedules with sizes and grades
• Connection details and hardware specifications
• Roof and floor structural systems
• Foundation design (see foundation section below)
• Full PE-stamped drawing set for permit submission
• Structural calculations package
• IBC, ASCE 7, and state code compliance

Adding onto an existing home or renovating a commercial space involves more complexity than new construction — you're tying new structural elements into an existing building that may be decades old. Our engineers evaluate the existing structure first, then design the addition or renovation to work with what's already there.

We handle everything from a single-room addition in Chester County to a multi-story commercial renovation in Philadelphia. We know the common structural challenges found in older Pennsylvania and Delaware housing stock — undersized beams, deteriorated framing, and foundations that weren't designed for added loads — and we address them practically.

• Structural evaluation of existing framing
• Room additions — single and multi-story
• Second-story additions over existing first floors
• Garage conversions and ADU structures
• Commercial tenant improvement structural work
• Structural drawings for permit submission
• Connection details for new-to-existing tie-ins
• Load path verification through existing structure

Structural load calculations are the engineering backbone behind every PE-stamped drawing we produce. They verify that every beam, column, connection, and foundation in your project can safely carry the loads it will see over its service life — gravity loads, snow, wind, and seismic where applicable.

Pennsylvania and New York have significant design snow loads. Texas Gulf Coast projects require hurricane wind analysis. Every location in our service states has its own ASCE 7 load requirements, and we apply the correct values for your specific project address — not generic conservative assumptions that add unnecessary cost to your structure.

• Dead load and live load analysis per IBC
• Snow load design per ASCE 7 (PA, NY, DE, TX)
• Wind load analysis — including hurricane zones (TX)
• Seismic analysis where applicable
• Beam sizing and span calculations
• Column and post load path analysis
• Connection design and hardware specification
• Complete calculations package for building department

A proper foundation design starts with understanding the soil beneath the structure. We work from geotechnical reports (soil borings or test pits) to design a foundation system that safely transfers the building's loads to the ground — without excessive settlement or failure.

We design all common foundation types used in our service states: spread footings for residential construction in Pennsylvania and Delaware, deep foundations and pile systems for challenging soils in Texas, and grade beams and piers for expansive clay conditions common in North and Central Texas. Our designs account for frost depth requirements in PA and NY.

• Spread footing design (residential and commercial)
• Continuous wall footings
• Grade beams and pier systems
• Pile cap design where deep foundations are required
• Frost depth analysis (PA, NY, DE)
• Expansive soil design (TX)
• Foundation drawings for permit submission
• Coordination with geotechnical report recommendations

A structural inspection by a licensed PE goes well beyond what a standard home inspector can provide. Our engineers evaluate the structural elements of a building — foundation, framing, load path, and visible structural components — and deliver a PE-stamped report with professional engineering findings and recommendations.

Structural inspection reports from NEC Solutions are commonly requested by home buyers before closing, lenders requiring structural verification, property investors evaluating a distressed or foreclosed property, and homeowners dealing with cracks, settling, or other structural concerns. Our reports are accepted by banks, insurance companies, and Pennsylvania and New York courts.

• Foundation and basement evaluation
• Structural framing assessment
• Identification of structural deficiencies
• Crack analysis and cause determination
• Load path verification
• Recommendations for repair or remediation
• PE-stamped written report delivered in 5–7 business days
• Accepted by lenders, insurers, and courts

Deck failures are one of the most common structural failures in residential construction — and they're almost always preventable with proper engineering. Whether you're building a simple ground-level deck or an elevated multi-level structure, getting the structural design right from the start protects your investment and your family.

Most Pennsylvania, Delaware, and New York building departments require PE-stamped drawings for attached decks — especially elevated decks more than 30 inches off the ground. We design the full deck structure: ledger attachment to the house, joist and beam sizing, post and footing design, and all connection hardware. Our drawings give your contractor clear direction and give your building department what they need for permit approval.

• Ledger attachment design and detail
• Joist sizing and span analysis
• Beam and post schedule
• Footing size and depth design
• Hardware and connection specifications
• Guard rail and lateral load design
• Screened porch and roof structure design
• PE-stamped drawings for building permit

Solar panel installations add real weight and wind load to your roof structure. Before your solar installer can get interconnection approval from the utility company — and before most building departments will issue a permit — they need a PE-stamped structural letter or drawing package confirming the roof can safely support the proposed solar array.

Our solar structural evaluations are fast and straightforward. We assess the existing roof framing (rafters or trusses), calculate the added dead load from the panel array, verify the wind uplift resistance, and confirm that the proposed racking attachment points are structurally adequate. Most solar letters are delivered in 3–5 business days and are accepted by PECO, PPL, Con Edison, PSEG Long Island, Oncor, CenterPoint, and other utilities across our service states.

• Existing roof framing assessment
• Dead load capacity verification
• Wind uplift analysis per ASCE 7
• Racking attachment point verification
• PE-stamped structural letter (3–5 business days)
• Full permit drawings where required by municipality
• Accepted by all major utilities in PA, NY, DE & TX
• Residential and commercial solar installations

Scaffolding and shoring are temporary structures, but they carry real loads and must be engineered with the same rigor as permanent construction. Improperly designed shoring or scaffolding is a leading cause of construction site accidents — a PE-stamped design is not just a code requirement in many jurisdictions, it's a critical safety measure.

We provide engineered shoring and scaffolding design for construction projects in Pennsylvania, New York, Delaware, and Texas. Whether you need a temporary shoring system to support a floor above an excavation, or a scaffolding layout for façade work on a commercial building, our designs account for all loads including construction live loads, material storage, equipment, and wind.

• Temporary shoring system design
• Excavation shoring and retaining analysis
• Scaffolding system design and layout
• Load capacity verification for existing floors
• Formwork and falsework engineering
• PE-stamped drawings for contractor use
• OSHA compliance in design approach
• Removal sequence and deshore procedure

A building permit application without complete, properly formatted structural drawings is a permit application that will be rejected. Building departments want to see organized, clearly labeled drawings that tell the complete structural story — and they want them stamped by a licensed PE.

We prepare complete structural permit drawing packages for projects in Pennsylvania, New York, Delaware, and Texas. Our packages are formatted to meet the specific requirements of each state and locality — including Philadelphia L&I, NYC Department of Buildings, New Castle County Land Use, and Texas municipal building departments. When your permit needs to go in right the first time, we make sure it does.

• Complete structural drawing set (all required sheets)
• Foundation plan and details
• Framing plans (floor and roof)
• Structural sections and details
• Calculations package
• General notes and code references
• PE stamp and signature on all structural sheets
• Plan review revision support at no extra charge
