“ANGIE’S LIST DISCOUNT” – My Angie’s List Clients are given a ten percent (10%) discount on my Fee since Angie’s List does not charge businesses to list their services; therefore, my marketing cost is zero ($0.00) for my Angie’s List Clients. “FINANCING” – Clients are requested to make payment by check with sufficient funds on deposit to cover the check. Should the client be unable to make timely payment then their project is placed on hold until payment is received.

No late fee ($0.00), no interest ($0.00), and no returned check fee ($0.00), is charged. “DESIGN/BUILD SERVICES FINANCING” – The cost of my services (Planning, Design, Engineering, Plans Drafting – CAD, Construction Management, & Inspection) is built into the “Construction Cost”; therefore, my services can be financed over the life of my Client’s mortgage. “EMPLOYEES” – Jonathan A. Snyder is a self-employed Professional Engineer, company of 1 person, who is networked with other qualified designers, engineers, and construction professionals. “PLANS PAYMENT” – Construction Plans are provided on either a “Fixed Fee” or “Not to Exceed Time & Expense” basis, payable in three (3) installments; 1/3 due at “Contract Signing”, 1/3 due at “Planning / Design Review”, 1/3 (or balance) due at “Delivery of Completed Plans”. “DESIGN/BUILD” – “SUB-CONTRACTING” and “PAYMENT”: LABOR – Construction Labor is bid by a minimum of three (3) Sub-contractors; all Bids are reviewed and presented to the Building Owner with recommendation on the “Lowest Qualifying Bid”; the Bid is awarded (Sub-contracted) to the contractor preferred by the Building Owner.

Structural Engineering questions, answered by experts

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

Their expertise in identifying potential problems early and implementing durable solutions safeguards your home’s integrity.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.
