FAQ
Frequently Asked Questions
Straight answers about how ONYRverse works, what we deliver, and where we draw the line.
Working with ONYRverse
What does ONYRverse Digital Designs do?
We serve the construction industry by using our architectural drafting skills to develop the construction work scope in blueprint form. That plan set is what allows funding, approvals, bidding and building. We coordinate every discipline and stakeholder so the plans are fundable, approvable and buildable.
How does the ONYRverse process start?
Complete the Design Brief intake form. We develop a pre-design concept package based on your answers, then schedule a consultation to review it with you and set up a retainer. The more you share up front, such as surveys, sketches, dimensions and photos, the faster the concept package comes together.
Is ONYRverse a contractor or an engineering firm?
ONYRverse is a design-build studio, not an engineering firm. You can hire us for design only, or have ONYRverse hold the build contract with our Site Construction Manager on site. Build pricing comes once the plans are done, cost plus by default, and we never guarantee a number before design. When a project requires stamped engineering, we coordinate with licensed Texas professionals and build their requirements into your plan set so nothing is missed at permit review.
Architectural Design
About this service →What is the difference between an architectural designer and an architect in Texas?
In Texas, the title architect is reserved for individuals licensed by the Texas Board of Architectural Examiners, and certain building types require an architect's seal. Many residential and smaller commercial projects can be designed by an architectural designer. ONYRverse provides architectural design and documentation, and if your project type requires a licensed architect or engineer to seal drawings, we coordinate with the appropriate licensed professionals.
Can you design a barndominium or shop house in Southeast Texas?
Yes. Barndominiums and shop houses are a natural fit for our process because they mix living space, open spans, and workshop or storage areas under one roof. We design the layout, exterior, and documentation, account for coastal wind requirements where they apply, and coordinate with the structural engineer on the building system so the plans are ready for permitting, financing, and either bidding or an ONYRverse build.
Do you tell me what my project will cost to build?
Not before the design exists, because a price without plans is a guess. We design with your budget targets from the start. If ONYRverse builds the project, you receive a build price once the plans are done, cost plus by default with fixed fees for mobilization and administration. If you choose design only, our documentation gives your builder a clear scope to price accurately and your lender a clear scope to evaluate.
Should I choose design only or design and build?
It depends on how involved you want to be. Design only fits owners who already have a builder or want competitive bids; you own the plans and take them to any builder. Design and build fits owners who want one point of contact, with ONYRverse holding the build contract, Evan Simon supervising the site, and a 1-year craftsmanship warranty on the work. We walk through both paths at your consultation.
How do I start an architectural design project with ONYRverse?
Start by completing the design brief intake form. Include any surveys, hand sketches, dimensions, photos of the existing site, and pictures of what you want. We use that information to develop a pre-design concept package, then schedule a consultation to review it with you and set up a retainer before full design begins.
Can you design renovations and additions to existing buildings?
Yes. Renovations and additions start with documenting existing conditions so the new design fits what is actually there. Our portfolio includes project types such as an insurance office renovation, an event venue renovation, and a church and school addition. We plan around existing structure, systems, and code requirements, and coordinate engineers when changes affect them.
Drafting & CDs
About this service →What is included in a set of construction documents?
A typical set includes a cover sheet and code summary, site plan, floor plans, exterior elevations, building sections, wall sections, details, and schedules. Depending on the project and jurisdiction, it also includes structural, mechanical, electrical, and plumbing sheets prepared by or coordinated with licensed engineers. We tailor the set to what your city or county requires for permit review.
What is the difference between architectural drafting and civil drafting?
Architectural drafting documents the building itself: plans, elevations, sections, and details. Civil drafting documents the site around it: building placement, grading, drainage, utilities, parking, and access. Most projects need both. ONYRverse handles both drafting types and coordinates with licensed civil engineers or surveyors when the site work requires their design or seal.
Can you create drawings of my existing building?
Yes. We prepare existing-conditions and as-built drawings from field measurements, any original plans you have, and site data. These drawings are useful for renovations, additions, insurance, refinancing, facility management, and property sales. For larger sites, drone data can support existing-conditions documentation where appropriate.
Will your drawings pass plan review the first time?
No one can honestly promise that, because plan review comments depend on the reviewer and the jurisdiction. What we can do is prepare the set against the local submittal requirements, keep every sheet consistent, and respond to comments quickly and clearly. Organized, coordinated drawings give reviewers fewer reasons to send a set back.
Can you draft from my hand sketches or a plan I found online?
Yes. Hand sketches, marked-up plans, and inspiration photos are a helpful starting point. We turn them into dimensioned, coordinated drawings and adjust the design so it fits your site, your local code requirements, and Southeast Texas conditions such as wind and drainage that a generic online plan may not address.
3D Modeling
About this service →What is the difference between a 3D model and a rendering?
A 3D model is the digital building itself, with real dimensions, walls, roofs, and openings. A rendering is an image produced from that model. We build accurate models first, then produce views from them, so the visuals reflect a design that can actually be documented and built rather than an artist's impression that has to be reworked later.
Can you create 3D visuals to show my lender or investors?
Yes. Lenders and investors want to understand what they are funding, and clear visuals paired with a defined scope help them evaluate a project faster. ONYRverse does not fund projects. We help make projects fundable by giving capital partners visuals and documentation that show a clear, coordinated plan instead of a rough concept.
Can I use the 3D model to choose finishes and exterior materials?
Yes. Comparing options side by side is one of the most practical uses of 3D modeling. You can review exterior colors, roof styles, siding, window arrangements, and interior layouts before committing. Making those decisions on screen is far cheaper than changing them during construction, and it keeps the finish schedule aligned with what you approved.
Do you model existing buildings for renovation projects?
Yes. For renovations and additions, we model the existing building from measurements, original plans, and site data so the new work can be tested against real conditions. That lets you see how an addition or interior change will fit before demolition starts, and it gives builders a clearer picture of the scope they are pricing.
Revit BIM
About this service →Do I need BIM for a small residential project?
Not always. For a simple home, a well-organized Revit model can still help by keeping plans, elevations, and schedules consistent, but a full multi-discipline BIM coordination process may be more than the project needs. During the BIM consultation we recommend the level of modeling that fits your project, so you pay for what actually reduces risk.
Can you coordinate models from outside engineers and consultants?
Yes. Coordinating consultant models is central to BIM management. We bring in structural and MEP models from licensed engineers, check them against the architecture, and track conflicts to resolution. Each engineer stays responsible for their own design, and ONYRverse keeps the combined model organized as the single current record for the project team.
What file formats do you deliver?
We work primarily in Autodesk Revit and can deliver native Revit files, PDF sheet sets, and exports in common exchange formats such as IFC or DWG when agreed in scope. We confirm formats early so builders, consultants, and facility teams receive files they can actually open and use in their own workflows.
Can a BIM model help with material takeoffs and procurement?
Yes. Because the model knows what each element is, it can produce component-based quantity schedules. After design approval, those schedules can be shared with builders and suppliers to confirm product selections, pricing, and delivery timing. ONYRverse does not sell materials, but the quantity information makes procurement coordination faster and more accurate, whether your builder or our own build team is ordering.
My builder uses 2D drawings. Is BIM still useful?
Yes. The builder does not need to open the model to benefit from it. BIM produces standard PDF construction documents that are more consistent because every sheet comes from one model. Behind those sheets, clashes have already been checked and schedules already match the drawings, which means fewer questions and fewer surprises once work starts.
Windstorm Design
About this service →Does ONYRverse issue WPI-8 windstorm certificates?
No. The WPI-8 certificate of compliance is issued through the Texas Department of Insurance windstorm program based on certification from a licensed engineer appointed as a qualified inspector. ONYRverse prepares windstorm-ready design documentation and coordinates with that engineer and inspector so the plans they review already show the load path and connections they need to verify.
Does my Beaumont or Port Arthur project need windstorm certification?
Jefferson County is in the TDI designated catastrophe area, so many new structures, additions, and certain repairs there are candidates for windstorm inspection and WPI-8 certification, especially if you want TWIA coverage. The exact requirement depends on the scope of work and your insurance needs. A Windstorm Design Review helps confirm the right path before drawings are finalized.
Why does TWIA care about windstorm certification?
TWIA provides windstorm and hail coverage along the Texas coast, and it generally requires proof that eligible structures in the designated catastrophe area were built or improved to the applicable windstorm building code. The WPI-8 is that proof. Without it, obtaining TWIA coverage can be difficult, which can also affect financing, since lenders typically require adequate insurance.
What wind speed will my building be designed for?
The design wind speed, exposure category, and related criteria are set by the building code adopted for your site and the ASCE 7 standard it references. They vary by location and building risk category. The licensed engineer on your project confirms those values and performs the wind design, and we carry the resulting requirements into the plan set and details.
Can windstorm details be added after a plan is already drawn?
Sometimes, but it is harder and usually costs more. Adding a continuous load path late can change framing, sheathing, openings, and foundation anchorage, which ripples through the whole set. If construction has already started, missing connectors may mean opening finished work. Bringing windstorm requirements into the design from the beginning is the simplest route to certification.
Structural Coordination
About this service →I searched for a structural engineer in Beaumont. Are you one?
No. ONYRverse designs, documents, and can build your project, but it is not an engineering firm. We coordinate your structural engineer. If your project needs sealed structural drawings, we work with licensed Texas professional engineers who take responsibility for that work, and we manage the exchange so their design fits cleanly into your plan set and permit submittal.
Can I use my own structural engineer?
Yes. If you already have a licensed engineer you trust, we will coordinate with them directly. We share the model and drawings, track their comments, and update the architectural sheets to match their design. If you do not have one, we can connect you with licensed professionals we coordinate with on other projects.
Does every project need a structural engineer?
Not always. Requirements depend on the building type, size, location, and what your local permitting office requires. Many commercial projects, larger homes, additions that change bearing walls, and coastal projects needing windstorm documentation typically involve an engineer. We help you find out early what your jurisdiction expects so there are no surprises at plan review.
What is FEA and will my project need it?
Finite Element Analysis is a computer method engineers use to study how a structure behaves under load. It is usually reserved for complex spans, unusual shapes, or heavy equipment. Your licensed engineer decides whether it is needed. If it is, ONYRverse supports the effort with accurate BIM geometry and folds the engineer's results back into the drawings.
How does structural coordination save money?
Industry research shows most of a project's cost is committed during design, and change orders during construction often add a meaningful percentage to budgets. When architectural and structural drawings disagree, builders either stop and ask or guess. Both cost money. Coordinating early means fewer field questions, cleaner bids, and fewer surprises once construction begins.
MEP Coordination
About this service →Does ONYRverse design the HVAC, electrical, and plumbing systems?
We coordinate them. ONYRverse is not an engineering firm and does not perform MEP engineering or seal drawings. When a project requires engineered MEP systems, we coordinate with licensed Texas professional engineers who design and seal them. We make sure their work fits the architecture and that every sheet in the set tells the same story.
What does MEP stand for?
MEP stands for mechanical, electrical, and plumbing. Mechanical usually means heating, ventilation, and air conditioning. Electrical covers service, power distribution, lighting, and emergency power. Plumbing covers water supply, drainage, venting, and fixtures. Together they are the systems that make a building livable and usable, and they take up more space than most owners expect.
When should MEP coordination start?
Earlier than most people think. The best time is during schematic design, before room sizes and ceiling heights are locked. Once walls, beams, and slabs are set, systems have to squeeze into whatever space is left. Starting early lets us reserve chases and equipment areas so the mechanical, electrical, and plumbing design has room to work.
Is MEP coordination worth it on a small commercial project?
Often yes. Small projects like coffee shops, offices, and retail spaces tend to pack a lot of equipment into little space. A commercial kitchen hood, a restroom group, and a rooftop unit can create more conflicts than a much larger building. Coordinating early helps avoid rework, field delays, and change orders that hit a small budget hard.
Can you coordinate MEP on a renovation of an existing building?
Yes. Renovations bring extra unknowns because existing systems are often undocumented. We review what is there, identify where new equipment and routes can realistically go, and coordinate with your engineers and builder on the existing conditions. Drone and site data can also help document conditions before design decisions are made.
Project Management
About this service →Can ONYRverse manage the construction too, or only the design?
Both, and you choose. On a design-build project, ONYRverse holds the build contract and provides site supervision through our Site Construction Manager, Evan Simon, with TRP Land Clearing and Excavation, N-Sink Plumbing, and licensed partner engineers on the team. If you prefer your own contractor, we manage the design and documentation side and hand your builder a clear, consistent, permit-ready set.
How is the build priced on a design-build project?
Pricing comes after the plans are done, never before. Our default is cost plus, meaning you pay the actual cost of the work plus fixed fees for mobilization and administration. We do not quote a guaranteed number before design, because the drawings are what make a price meaningful. Designing to your budget targets from the start keeps that price connected to what you planned.
Why hire project management during design instead of construction?
Industry research shows 70 to 80 percent of project cost is committed during design, and fixing a problem during construction can cost six to ten times more than fixing it on paper. Managing the design phase well is where owners have the most control over budget and schedule. By construction, most of the big decisions are already made.
What types of projects do you manage?
We support industrial, commercial, and municipal projects across Southeast Texas, along with complex residential work. Project types we have supported include law offices, insurance office renovations, church and school additions, coffee shops, retail new construction, event venues, barndominiums, and tiny homes. Every project gets the same structured process scaled to its complexity.
How do you work with public agencies on municipal projects?
Municipal projects add review boards, public input, and procurement requirements. We map every agency stakeholder early, build their review steps into the schedule, and track their comments like any other input. The goal is to keep the documentation aligned with agency requirements so approvals move forward without repeated rounds of revisions.
Can you step in on a project that is already underway?
Yes. Many clients come to us when a project has stalled because of conflicting drawings, unresolved engineer comments, or plan review problems. We start by reviewing where things stand, listing open issues, and identifying who owns each one. From there we build a path to a consistent, permit-ready set.
Drone Mapping
About this service →Can drone mapping replace a land survey?
No. Our aerial mapping is a planning, design, and communication tool. It is not a certified survey and does not establish property boundaries, easements, or legal descriptions. If your lender, title company, or permitting office requires a survey, you need a Registered Professional Land Surveyor. We coordinate our design work with their survey when one is part of the project.
How often should progress flights happen during construction?
It depends on the project's pace and who is watching it. Some owners want monthly updates for lenders, while fast-moving commercial projects may benefit from more frequent flights around key milestones like foundation, framing, and dry-in. We build a capture schedule around your milestones and reporting needs rather than a one-size plan.
What happens if the weather is bad on flight day?
Drone flights depend on wind, rain, and visibility, and Southeast Texas weather can change quickly, especially during summer storm and hurricane season. If conditions are not safe or would compromise image quality, we reschedule. Building some flexibility into the capture plan keeps progress documentation consistent without forcing a flight in poor conditions.
Do I have to be a design client to use your drone services?
No, though the data is most valuable when it connects to design and project management. Owners and builders can use aerial capture for site planning or progress monitoring on its own. When ONYRverse is also handling the design, documentation, or the build itself, we fold the imagery directly into models and plan reviews, which is where it saves the most time.
Can aerial imagery help with a renovation or addition?
Yes. Additions and renovations depend on understanding what is already there. Aerial imagery shows roof shapes, existing structures, drainage, trees, and how the building sits on the lot. That context helps us plan the addition, spot conflicts early, and give your design team and engineers a clearer picture before detailed design begins.
AR Walkthroughs
About this service →Do I need a headset or a special app to view an AR walkthrough?
No. Our walkthroughs are delivered as USDZ files, which iPhone and iPad open natively. You tap the file, point your camera at the ground, and place the model. For people who are not on an iPhone, we also provide a version that opens in a web browser, so lenders, partners, and family members can view it without buying anything.
Can I stand on my empty lot and see the building at full size?
Yes. That is one of the most useful ways to use it. You place the model on the lot at full scale and walk around and through it, checking how it sits relative to trees, drives, and neighbors. Keep in mind AR placement is visual and approximate. Exact building location still comes from the survey and the dimensioned site plan.
Can a whole subdivision or multi-building development be shown in AR?
Yes. We export whole scenes, not just single buildings. A property development with several structures, parking, and drives can be placed as one scene so investors, lenders, or a city audience can see how the site works together. Large scenes can also be scaled down to tabletop size for presentations in a conference room or at a meeting.
Will the AR model change if my design changes?
It should, and that is the point of building it from Revit. The AR file is exported from the same model that produces your plans. When the design is revised, we update the model and generate a new export at the milestones we agree on, so nobody is walking through an old version while the drawings have moved on.
Is an AR walkthrough worth it for a small residential project?
Often, yes. Small projects have small margins, and a single late change to a wall, window, or ceiling height can take a real bite out of the budget. Walking a tiny home, barndominium, or addition at full scale before approving the layout is an inexpensive way to catch those changes while they only require editing a model.
Cinematic Renderings
About this service →What is Twinmotion and why do you use it with Revit?
Twinmotion is a real-time visualization platform that pairs well with Revit. We design in Revit so the geometry is accurate, then export into Twinmotion to add materials, landscaping, lighting, and cameras. Real-time rendering lets us test views and time of day quickly and produce polished video and stills without rebuilding the design in a separate program.
Can a cinematic video help me raise money for my project?
It can make your pitch much clearer, which is what investors, donors, and lenders respond to. A short film shows what the finished project will look and feel like in a way a plan set cannot. It works best alongside a defined scope and coordinated documents. ONYRverse does not fund projects, but we help present them in a fundable way.
Can you show my building at night or in different seasons?
Yes. Because the scene is built in Twinmotion, we can render the same design at midday, sunset, and night, and adjust vegetation and weather for different moods. Evening views are especially useful for restaurants, retail, event venues, and churches, where exterior lighting and glowing windows are a big part of how the building will be experienced.
What if my design changes after the video is made?
Because the production is driven by the Revit model, design changes can be carried into the Twinmotion scene rather than starting over. The amount of rework depends on how much changed and which shots are affected. We recommend scheduling the final render after the design is approved, with draft stills earlier for decision making.
Are the furniture, trees, and people in the renderings part of my project?
Usually not. Furniture, artwork, people, vehicles, and most landscaping are added to make the scene read naturally and are illustrative unless they are included in your construction or landscape scope. We keep the building itself faithful to the drawings and flag illustrative elements, so nobody mistakes set dressing for a promise.
Feasibility Planning
About this service →What is a feasibility study for a building project?
It is an early investigation that tests whether a project makes sense before you invest in full design. We look at the site, the rules that apply to it, what you need to build, and how that fits your financial targets. The outcome is a concept and a clear recommendation to proceed, adjust the plan, or stop before larger costs are committed.
Can you tell me if my lot is buildable before I buy it?
We can investigate the questions that usually decide it, such as flood zone, permitting authority, setbacks, access, septic needs, windstorm area, and whether your intended building fits. That research helps you make a better purchase decision. It does not replace a title review, a boundary survey, or professional legal advice, which we recommend before closing on any property.
Why won't ONYRverse quote a construction cost during feasibility?
Construction pricing depends on builders, labor markets, materials, and site conditions that a designer does not control, and we do not want to give you false confidence. Instead, we design around your budget targets and identify the decisions that drive cost. If you later choose design and build with us, the build price comes after the plans are complete, never before.
What is a Moasure device and how is it used on my site?
A Moasure is a handheld measuring tool that records distances and elevation changes as you move it across a site. We use it for elevation assessments, alongside drone capture and lidar scanning, to understand how the land slopes and where water may collect. Those findings guide slab height, building placement, and drainage planning during concept design.
Does feasibility planning carry over if I move into full design?
Yes. Nothing is thrown away. The site data, code research, program, and approved concept become the starting point for architectural design and construction documents. That is why feasibility is usually the first step in the ONYRverse process, and why projects that start with it tend to move through design with fewer surprises and redesigns.
Structural Drafting
About this service →If ONYRverse drafts the structural sheets, who is responsible for the design?
The licensed Texas professional engineer who seals the drawings is responsible for the structural design. ONYRverse prepares the drafting from that engineer's design and keeps it aligned with the architecture. We do not calculate loads, size members independently, or stamp drawings. Our partner engineers include Innodez and Aaron & Franklin, and we can also draft for your own engineer.
What sheets are usually in a structural drawing set?
A typical set includes general structural notes, a foundation plan, floor and roof framing plans, building and wall sections, typical details, and schedules for headers, beams, columns, and connections. Larger or coastal projects may add shear wall plans, strap and hold-down schedules, and steel or truss references. The engineer decides what the project requires, and we draft each sheet to match.
Can you draft structural plans for a metal building or barndominium?
Yes. Barndominiums and shop houses often combine a manufacturer's metal building package with a custom slab and interior framing. We draft the foundation plan, anchor bolt layout, interior framing, and sections the engineer designs, and we reference the metal building supplier's drawings so the builder knows which document governs the frames, purlins, and girts versus the site-built portions.
Do I need a soil report before you draft the foundation plan?
It depends on the project and what your engineer and jurisdiction require. Many Southeast Texas sites have expansive clay, so engineers often want a geotechnical report before finalizing a foundation design. When one is needed, we coordinate it with a licensed geotechnical engineer. We draft the foundation plan after the engineer has designed it from that information.
Are your structural drawings part of windstorm documentation?
They can be. For projects in the windstorm catastrophe area, the connection details, strap schedules, and load path callouts we draft become part of the windstorm-ready documentation. The design comes from a licensed engineer, and WPI-8 certification comes from a TDI-appointed qualified inspector or licensed engineer. ONYRverse prepares the drawings; we never issue windstorm certification.
Mechanical Drafting
About this service →Does ONYRverse size my HVAC system or run Manual J calculations?
No. Load calculations, equipment selection, and duct sizing are design decisions made by a licensed mechanical engineer, typically our MEP partner Innodez, or by the engineer on your team. ONYRverse drafts the mechanical sheets from that design, keeps them consistent with the architecture in Revit, and turns engineer redlines into clean revised sheets ready for permit and bidding.
Why do I need mechanical drawings if my HVAC contractor can figure it out?
On many commercial projects the jurisdiction requires mechanical drawings for permit, and even when it does not, drawings let several contractors bid the same scope. Without them, each bidder imagines a different system, and the cheapest bid may leave out ductwork, exhaust, or ventilation you need. Clear sheets protect your budget and make installed work easier to inspect.
Can you draft ductwork for an existing building we are renovating?
Yes. We start by documenting existing conditions, including attic space, chases, ceiling heights, and equipment locations, then draft the new or modified system the engineer designs. Drawing from verified conditions keeps new duct routes realistic and reduces surprises when the ceiling comes down. This is especially useful for older commercial buildings and church or school additions.
Do your mechanical sheets show where rooftop units sit on the roof framing?
They do. Because mechanical and structural sheets are drafted in the same Revit model, rooftop unit locations, curbs, and supports are drawn against the roof framing the structural engineer designed. If a unit lands where the framing cannot carry it, we flag it for the engineers before the sheets are issued, instead of leaving the problem for the field.
Electrical Drafting
About this service →Who decides the size of my electrical service and panels?
A licensed electrical engineer decides, typically our MEP partner Innodez or the engineer already on your project. They calculate loads, size the service, feeders, and breakers, and select panels. ONYRverse drafts the one-line diagram, panel schedules, and plans from that design. We never size electrical equipment ourselves, and we never seal electrical drawings.
What is the difference between a power plan and a lighting plan?
A power plan shows receptacles, dedicated circuits, and connections to equipment such as HVAC units, water heaters, and kitchen appliances. A lighting plan shows light fixtures, switches, and control zones, usually drawn over the reflected ceiling plan. Smaller projects may combine them on one sheet. Larger projects separate them so each sheet stays readable for the electrician.
Can you draft electrical plans for a coffee shop or small restaurant buildout?
Yes. Food service spaces carry heavy equipment loads, dedicated circuits, and specific receptacle locations for espresso machines, ovens, coolers, and point of sale stations. We draft the power plan around the owner's equipment layout, and the engineer circuits it. Getting the equipment list settled early helps the electrical design, and the drafting, stay stable through permitting.
Why do plan reviewers care so much about the one-line diagram?
The one-line diagram is the fastest way for a reviewer to understand how a building's electrical system is fed and protected. It shows the service, main disconnect, panels, and feeders on a single page. If it disagrees with the panel schedules or floor plans, the reviewer will likely issue comments, so we draft it to match both exactly.
Plumbing Drafting
About this service →Does ONYRverse size the pipes on my plumbing plans?
No. Pipe sizing, fixture unit calculations, slopes, and vent design are made by a licensed professional, typically our MEP partner Innodez or the designer already on your project. ONYRverse drafts the supply plans, DWV layouts, riser diagrams, and fixture schedules from that design, and keeps them aligned with your architectural and structural sheets in the shared Revit model.
Why does underslab plumbing need such careful drafting?
On slab-on-grade construction, drain lines and fixture rough-ins are cast into the concrete. If a toilet, floor drain, or shower drain is in the wrong place, fixing it means cutting and patching the slab. Careful drafting dimensions every location, routes pipe around foundation beams, and matches sleeves to the foundation plan, so the pour captures the right layout.
What is a riser diagram and do I need one?
A riser diagram shows plumbing in a vertical view, illustrating how fixtures drain into branches and stacks and how vents connect through the roof. Commercial and multi-story projects usually include one, and many jurisdictions expect it for review. Even on smaller buildings, it helps plumbers and inspectors understand the system faster than plan views alone.
Can you draft plumbing for a property on septic instead of city sewer?
We can draft the building plumbing and show the connection point to an on-site sewage system. The septic system itself must be designed by an appropriately licensed professional and permitted through the county or local authority. We coordinate the building sheets with that designer's layout so the building drain exits where the septic system expects it.
Civil Drafting
About this service →Do I need civil drawings for a single house or barndominium?
Often you need at least a site plan showing the building, setbacks, drive, and utilities, and some jurisdictions or lenders also want grading or drainage information, especially in flood-prone areas. Requirements vary by city and county. We confirm what your permitting authority expects for your address and scale the drawings to match, so you are not paying for sheets nobody asked for.
Can ONYRverse seal a site plan or drainage plan?
No. ONYRverse prepares civil and site drafting, but we do not seal drawings or design drainage systems. When a sealed plan is required, a licensed Texas professional engineer designs and seals it. We draft to that engineer's direction and coordinate the site sheets with the architectural set, so you receive one consistent package ready for review.
Why does grading matter so much in Southeast Texas?
The region is flat and low, heavy rain is common, and small elevation differences decide where water goes. A building pad set too low or a drive that blocks natural flow can cause standing water, flooding, or problems with neighbors. Grading and drainage sheets make the intended water path clear before construction, when correcting it is still inexpensive.
Can site preparation contractors work from your drawings?
Yes, that is part of the purpose. Clear layout, grading, and drainage sheets give site preparation contractors the pad locations, elevations, culvert positions, and drive layouts they need for clearing, fill, and pad building. Once the engineer has approved the design, our drawings help those crews build it as intended and reduce guesswork in the field.
Is a drone map good enough to use instead of a survey for civil drafting?
No. Drone, lidar, and Moasure data are excellent for context and early planning, but civil drawings for permitting and construction should be based on a boundary and topographic survey from a registered professional land surveyor. We use our capture data to supplement the survey and to help everyone visualize the site, not to replace it.
