An outer perimeter of rebar is a must to tie all corners of the slab together. When any openings are encountered, you should double the rebar and thicken the width and depth of the concrete and pour a grade beam to help bear the weight and anchor the side posts of opening to the slab. Wire mesh for re-enforcing the slab should be tied to the perimeter rebar and rebar 'chairs' should lift the rebar to float in the middle of the concrete slab. Do not rely on someone lifting the wire mesh as you are pouring. | An outer perimeter of rebar is a must to tie all corners of the slab together.

In-floor heating lines should be laid in work zones and above the wire mesh. Header pipes should be staked as stated above and all joints in lines should be ABOVE the concrete. Risers should be rigid conduit for mechanical protection but horizontal runs work better in plastic conduit; no galvanic reaction takes place with the cement and if wires go to ground inside the pipe (not likely, but it happens) they won't weld themselves to the inside walls. That means you can always pull them back out. |
Some people prefer a curb around the perimeter of the building, rather than a slab. The reason for the curb is that it will keep out moisture, insects, etc. When pouring floors, always have a rotating laser level on hand and double check levels as the pour and leveling goes on. Grade floor from corners to middle, and center of space to outdoor openings. Put a sump pit in large buildings to collect runoff water and use a gravity drain or pump out system to remove it. Increase floor thickness in areas where you are using a lift or have heavy shop equipment. | Some people prefer a curb around the perimeter of the building, rather than a slab.

Sixteen feet is minimum if you are planning on a mezzanine for storage and office areas. If your codes prevent you from having a tall roofline for a 12 foot ceiling , you can do a 10 foot wall and use scissor trusses to gain more ceiling height inside the shop or if you have a steep roof you can have them install a cutout area so you can install a lift and have plenty of ceiling height. |

Everyone has an opinion and it is usually the depth of your pockets that dictate what you build. Try and make the walls rhyme in with the decor of the surrounding area. A red barn is quaint, but will look out of place in "Yuppyville". Neighbors tend to complain less if you "blend in". |
If your local code allows it, consider using 2x6 lumber for conventionally-framed structures. It reduces the number of studs (24" O.C. vs 16" O.C.), and allows more insulation in the wall cavities. While possibly more expensive, in the long term, the better insulating capabilities offered will offset the price. | If your local code allows it, consider using 2x6 lumber for conventionally-framed structures.

Insulation will also deaden the noise that you produce in your shop. Remember the last time you used an air chisel to remove that rusted body panel at 11:30 pm? Or the sound of the last thunderstorm that passed over your steel roofed shed! Try using as much insulation as you can afford. It will pay you back double or triple over the original cost you invested. Don't forget the vapor barrier, at least 6 mil plastic. Seal the electrical outlet boxes on the outside wall to prevent moisture infiltration into the insulation and wall section. |

You can cover the whole wall first, and then cut out the window openings. You can use the cutouts as inner shutters to cover over the windows that you want to make more secure, and hold them on with stud screws and wing nuts. Steel sheeting can be used much the same way if you are lining your building with it. Window bars and grilles are an option. |
Main doors should be placed so as to allow you the best access to where you need to go. Door frames should be rugged enough to hold a solid core door of either wood or commercial steel. Residential doors just don't cut it when it comes to security and protecting thousands of dollars of equipment, tools and projects that you have in your building. Outward swing doors offer more security and provide better emergency access if you should ever have to use it for that purpose. | Main doors should be placed so as to allow you the best access to where you need to go.

Door location is paramount in the setting up of your garage or shop. It doesn't matter if it is the decision between using a single door or two doors on a small garage, or if you should put the door in the middle of the end walls of a large shop. Take out the graph paper and draw your garage or shop area out to scale. Use scale sized piece of paper or wood blocks of 10 X 20 foot dimension to "drive" into your garage and park your vehicles to simulate what is practical for your building size. Sometimes, offsetting an end wall door and parking diagonally will give you better access and utilization of your space. Try going double deep with the garage on a deep lot property, install a OHD on either end, use the back end to move cars under construction into rear yard for sandblasting and painting, while the front end is used for everyday use of the family vehicles. This keeps the neighborhood from getting down on your case. | Door location is paramount in the setting up of your garage or shop.

| − | ==Electrical | + | ==Electrical== |
| − | + | Rule #1: The supply MUST meet the demand with a safety factor of at least 40%. Start with a 100 amp service. 'Demand' fits in two categories; DEDICATED circuits and CONVENIENCE circuits. Lighting, compressors, welders, post hoists, ventilation fans & heating units, reel-trouble lights, refrigerators, etc., are DEDICATED. Bench and wall receptacles are CONVENIENCE, because you're never going to use them all at once. Sit down with a clean sheet of paper and document the electrical tools that normally don't move and consider each circuit and amperage. Some circuits may be used for two purposes, for example, I doubt if anyone would raise a hoist while using the MIG welder. So, that can be the same circuit. Figure for liberal lighting and NEVER put lights on the same circuits as your receptacles. If you trip a breaker (or GFCI) you won't be groping around in the dark. Add the number of circuits and note the circuit's ampacity. Total your amps and multiply by TWO (because we know you're going to get more)and that's what service you'll need. Service panels come by AMPACITY and NUMBER of SPACES. 230-volt breakers occupy two spaces. A typical Service Panel will have a 100amp main breaker and 24 spaces. You can go up from here if more spaces or more ampacity is required. | |

| − | + | ||
| + | For CONVENIENCE receptacles, use #12AWG copper wire on 20-amp circuit breakers. 30-amp receptacles are normally dedicated to a stationary tool and rarely used as 'convenience' outlets. Don't forget that indoor and outdoor receptacles in a garage must be protected by GFCI's (either ground fault circuit interrupter breakers or GFCI outlets). If you protect the first of the outlet boxes in a circuit with a GFCI outlet, all the rest of the outlets may be protected too. A compressor or 220V mig will eat up 30 - 40 amps. Two-post hoists and 230volt MIG welders normally require 20-amps. "Brown outs", lack of correct power will fry a motor over time. If that shop of yours is getting a regular workout, maybe you should go with a new 'drop' instead of drawing off the house circuit. Better yet, stay away from using aluminum wire. Use copper because it rarely needs future attention, wire sizes are smaller for the same amperage, and it has a far better voltage drop over long runs. Electrical supply stores have copper wire in all sizes if your local 'box' store doesn't have it. | ||
| + | Motion detectors work great and are a deterrent to crooks. Point one at or above your entrance door (I also have one inside my garage for when the wife pulls the car in). This is particularly useful in winter months when days are short and weather is cold. BTW, if you live up north, stay away from fluorescent or any lights that use ballasts because if they start, they take a while to put out decent light. Use lighting fixtures that take regular light bulbs with standard 'medium' bases. Fluorescent lighting is fine in heated areas. | ||
| − | + | Consider running all your wires in metal conduit, surface mounted on the interior walls. If you get your shop all wired up and the wires are buried in the walls, it will be inconvenient to change anything later. If you don't like the look of exposed pipe, notch your studs and use thinwall (EMT) conduit. I keep my shop fireproof by using plasterboard (gypsum). It's cheap, clean, warm, durable and easy to repair. Oh, and a torch will not go through it. Bending thinwall is simple with practice. Have an electrician show you how the bender works because there's a lot more than meets the eye. | |
| − | It's nice to have a shower in the shop, especially after sanding fiberglass filler (this also prevents complaints from your spouse about the oil slick you leave in the bathroom after showering. If your budget warrants it and you have the room, a 800 to 1200 gallon holding tank is a great investment to hold the sewage and grunge that comes out of a garage. You can also put in a floor drain connected to a dry well to take gray water from washing your vehicles. Check your local building codes to see if they are allowed in your area, and don't be tempted to use the floor drain to get rid of anything else. | + | Electricity is very dangerous, and should be handled by qualified Journeyman Electricians. They adhere to the National Electrical Code book, written by the National Fire Protection Agency. You want this level of training and you want their work inspected for insurance purposes. Most cities offer 'Homeowner's Electrical Permits' at a reduced cost. It's perfectly ok to do this work yourself; just hire qualified help. Most inspectors are eager to work with homeowners if they get permits BEFORE work starts. They gladly answer your questions and give sound direction. When an inspector finds "bootleg" work, that's when they get upset, and naturally so. |

| + | Plumbing is a welcome addition to any shop. No more running to the house for a pail of water to fill the radiator or wash off body filler dust. You want water close by if you weld or grind. Getting water to the shop is easy -- getting sewage and gunk away is the problem. Limiting factors effecting effluent disposal are climatic conditions, topography, municipal concerns, and about twenty other things. | ||

| + | Garages have always been social places, but it seems that we are seeking more and more creature comforts coming into the garage each day. If it's cold out, heat it. If it's hot, cool it. It's that simple! No one wants to be working with sweat dripping from their crotch, so why would you want to do that in your garage. If you're welding, spraying paint or have grinding dust, you need ventilation. A wall type ventilator fan with exterior shutters is excellent, even a squirrel cage furnace fan stuck up in the gable end wall in the attic area will take away a majority of the noxious fumes and dust particles. A fresh air source is mandatory if you're using any kind of fossil fuel for heating. A CO2 monitor is also a good idea in a garage. | ||
Yes, you should have air conditioning. If you're comfortable, you'll stay in the garage longer and out of your spouse's hair.

Make sure that shelves are capable of handling the weight that you will place on them. One option is to use wire adjustable shelving -- it comes in varying widths and lengths, the dirt and dust falls right through, and you never have to climb up to see what's on the top shelf. Add colored bins and boxes, and it starts to look like a well organized shop. One option for independent shelving units are the "Gorilla" shelf units, available at Costco. The "Gorilla" shelves have a powder-coated angle iron frame with high density wood shelves, and are diagonally braced to prevent shifting. If you're worried about shelf units tipping, just add a turnbuckle, or a hook and eye from the wall to the unit for extra stability. |
