Structural design for residential and commercial. New , renovation, addition and underpinning. Licensed professional Engineer in DC, MD and VA We take great pride in our experience, expertise, quality and customer service that we provide to meet every consumer's needs. It is our mission to provide excellent customer service from start to completion of a project. To understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a personal and professional manner.

"Working with Zign Consulting has been the bright spot in an otherwise complex construction project. From the beginning, Zign Consulting was everything you hope for: honest, direct, highly capable, and urgent. After months of delays and complications caused by a previous architect, Zign Consulting stepped in and immediately brought clarity and direction. They swiftly got our plans completed and approved by DCRA—something the original architect struggled with for nearly a year. Their communication was transparent, their timelines were accurate, and their professionalism was unmatched. If you're looking for an architectural consultant who will advocate for your project and get things done the right way, Zign Consulting is the firm to hire. I can't recommend them enough."

"quality of work is good. One issue was they tried to change agreed upon price after work was completed, however, they did honor original estimate.

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

FAQs for engineer structural projects in Rockville, MD

The right type of engineer depends on the house you’re looking to build. Most builders work with structural engineers to ensure safety of the structure itself. For builds beyond a typical home up to 3,000 square feet, you might need a construction engineer.

Engineers work in a variety of fields, specializing in anything from structural to electrical work. Some work independently and are hired by large construction companies for complex projects. Others form engineering firms that oversee the entire construction project. They spend time on construction sites, but also work in offices to make calculations and prepare recommendations.

All 50 states require licenses for building engineers. Don’t work with a professional who doesn’t have an active license or doesn’t want to share their licensing number with you. It’s a crucial step in making sure you’re working with a reputable expert.

When you build an extension, you most likely need a structural engineer. They’ll work with the builder to make sure the space is safe, but also make sure that your addition follows the right zoning laws.

Loft conversions generally call for an engineer. The project will include working with beams and trusses that most likely hold up your roof or other parts of your home. You need a pro who can calculate the impact of making any changes.

Structural engineering is technically a subset of civil engineering. Most commonly in residential projects, civil engineers are accountable for sewage, water, and drainage, while structural engineers focus on the structure and its integrity.

Structural and architectural engineering are very similar. Both work with architects to make sure the designs don’t just look good but will hold up. The former is typically involved early on, making initial calculations. The latter is more closely involved with the architect, carrying a design from initial concept to actual build.

Hiring a structural engineer costs between $300 and $650 for most homeowners. The price is typically fixed at the beginning of the engagement. Your budget may need to range upwards of $1,250 if the pro doesn’t just provide an initial evaluation but partners with you throughout the construction.
