Building a Houseâ€Advice From an Architect

Building a House- Advice From an Architect While your new house is an exciting and mind-boggling experience for you, it is routine for the builder (been there, done that). These attitudes often tend to clash. Building your new house should not (and cannot) be a passive exercise. A myriad of decisions have to be made  - by you. When you are unable or unwilling to make decisions, you force the builder to make them. To make sure your new home fulfills your own vision, follow the following guidelines. Understand Your Contract No matter what type of contract you sign, you become a party to a legal document involving a massive amount of money for the construction of your new house. By so doing, you abdicate none of your basic legal rights. Therefore, know your rights and exercise them. Start by reading the contract and understanding it. You are paying (or will pay over the next 25 to 30 years) for the knowledge of the builders: their experience and ability. Plus you are paying your builders a profit above their expenses. What do you expect in return? How do you ensure that you get what you expect? COMMUNICATE  - WRITE IT DOWN  - COMMUNICATE  - WRITE IT DOWN  - COMMUNICATE  - WRITE IT DOWN. Anything you add to the house after the contract is signed, the builder will keep track of  - assiduously! Anything you delete or reduce, YOU keep track of  - assiduously! Save on Building Costs The average house contains approximately 1,500 to 2,000 square feet. Do you need more space than that? Why? How much more? You pay for each and every square foot of space in your house, whether its occupied, usable, or otherwise. If the cost is $50, $85, or $110 per square foot, extra, unused, vacant, and unnecessary areas are provided at the very same cost. You want to be in control of building costs, but you dont want to skimp. Keep costs in perspective; for example, that cost of $10-per-thousand more for a brick you really like translates into a total cost of only $100 more when a typical amount of 10,000 bricks is involved. Do the math yourself. Be smart. Take care that glitz and gadgets suggested by friends, the builder, or magazines do not overwhelm good basic construction. Dont trade them for lesser construction. Bouncy floors where joists are stretched to the maximum are not remedied by a hot tub, flocked wallcovering, skylights, or jazzy door hardware. Know what you like. Check Building Codes Dont expect to control the number of nails used. Do expect a substantially built house, free of defects, and in accord with all applicable codes and regulations. Require proof of such compliance (many jurisdictions issue Certificates of Occupancy) at the closing of your mortgage. This indicates accord with the minimum code and safety standards. Realize that some things are virtually unchangeable; they should be done properly, first off. This includes a properly sized and constructed foundation system, a properly designed and installed structural system, and so on. Changeable items such as finishes and coverings should not distract you from watching for and requiring good basic construction. Watch for things that are not necessarily what you want and that you will not be able to change easily or cheaply. Question things that just dont look or seem right. Most of the time they indeed are not. Seek some reliable outside, impartial advice- other than your father, even if he is a builder! Be Flexible Be ready and prepared to compromise in order to resolve situations and problems. Be aware, however, of what you may be giving up in this process;  examine and understand both sides. Is the situation worth what you are losing? The builder is fully capable of doing anything or finding someone who can do anything you wish, but anything always comes with a price. Be careful and wary of unique, inordinate, or far-out requests, new technology, and untested materials and equipment. Understand that construction is an imperfect science. Combine that understanding with natural elements (e.g., site conditions, weather, wood members, human foibles), and you might face situations where things could change, must be changed, or simply exceed capabilities. Flat-out errors do happen. Absolute perfection or your idea of perfection may not- and more than likely, will not- be achieved. Drastic imperfections, however, can be corrected, and they should be. It is within your rights to require this. Keep Records Issues not clearly and specifically noted, written, described, or shown will be interpreted by both sides. A meeting of minds must take place, where interpretations are fully understood and resolved. When this resolution does not happen, expect dispute, confrontation, pique, anger, frustration, and perhaps even litigation. Be redundant,  leaving nothing to chance. Follow up verbal discussions and instructions with written verification. Keep records and receipts; records of phone calls and all correspondence; samples you approve; sales slips; model, type, and style numbers; and the like. Dont allow yourself to be reduced to buying any aspect of a pig in a poke. The more time and effort spent up front in programming, planning, designing, and understanding, as well as in establishing specifics of the project, the better the chance for a smoother construction period and a satisfactory result. Be Businesslike Be pragmatic and absolutely businesslike in all of your dealings with the builders. They are working for you; you are not seeking them as new friends. If a friend or relative performs part of the work, treat that person in exactly the same manner:  have a contract and demand adherence to your schedule. Dont let a gift or a good price disrupt the project overall. Summary of Questions to Ask What is a good design for our needs?What is a building code? Does it affect us? How does it work? What doesnt it do?Who is responsible, overall, for my building project?What are good sizes and proportions for rooms? What style do I want?What am I really getting from the builder?What problems do I have in my current house that I dont want to repeat?Where can I find answers and help? How do I make my desires known?What does that line on the drawing mean?What is a dispute? What is a lien?What are specifications? Does the builder write and provide them?What if my builder does something in a way I dont like? Is the house going to be complete? Will something be left out?When will the house be finished?What is a contract? How do I play a part in it? What does it say?What is an extra?Is that a good material? Ive never heard of it.Can I change things?Who picks the color of the paint, wall coverings, tile, type of wood, siding?Is landscaping included and what form does it take? Sod? Seed? Mud and rocks? Slopes? Are landscape features guaranteed? What if I disagree with the builder? Can I stop the work?Am I allowed on the job site? Can I inspect the work as it goes up? Can I bring someone with me?I really want this xyz in the house. How do I get exactly that?I can buy the light fixtures from my brother, but who will hang them? What do I do?Should I close on the mortgage and pay the builder in full? I have several items that I dont like. Must I still close?Why do we have to make all these trips to pick things out?

Apollo 4 - NASAs First All Up Test

Apollo 4 - NASA's First All Up Test On January 27, 1967, tragedy struck on the launch pad during a preflight test for Apollo 1 (also called AS-204), which was scheduled to be the first Apollo manned mission, and would have been launched on February 21, 1967. Astronauts Virgil Grissom, Edward White, and Roger Chaffee lost their lives when a fire swept through the Command Module (CM). The accident was the first major mishap in NASAs short history, and it shocked the nation.   Moving Beyond Tragedy NASA made an exhaustive investigation of the fire (as it does with all space mishaps), which resulted in extensive reworking of the CMs. The agency postponed manned launches until officials cleared the new capsule design for use by human crews. In addition, Saturn 1B schedules were suspended for nearly a year, and the launch vehicle that finally bore the designation AS-204 carried a Lunar Module (LM) as the payload, not the Apollo CM. The missions of AS-201 and AS-202 with Apollo spacecraft aboard had been unofficially known as Apollo 1 and Apollo 2 missions (AS-203 carried only the aerodynamic nose cone). In the spring of 1967, NASAs Associate Administrator for Manned Space Flight, Dr. George E. Mueller, announced that the mission originally scheduled for Grissom, White and Chaffee would be known as Apollo 1, as a way to honor the three astronauts. The first Saturn V launch, scheduled for November 1967, would be known as Apollo 4. No missions or flights were ever designated as Apoll o 2 and Apollo 3.    The delays caused by the fire were bad enough, but NASA also faced budgetary cutbacks as it raced to reach the Moon before the end of the decade. Since the U.S. was in a race to get to the Moon before the Soviets could get there, NASA had no choice to but move ahead with the assets it had. The agency did further tests on the rockets, and eventually scheduled the Apollo 4 mission for an unmanned flight.  It was referred to as  all-up testing. Resuming Space Flight After the complete retooling of the capsule, the mission planners for Apollo 4 had four major goals: Demonstrate structural and thermal integrity and compatibility of launch vehicle and spacecraft; confirm launch loads and dynamic characteristics.Verify operation of command module heatshield (adequacy of Block II design for reentry at lunar return conditions), service propulsion system (SPS; including no ullage start), and selective subsystems.Evaluate performance of emergency detection system in open-loop configuration.Demonstrate mission support facilities and operations needed for launch, mission conduct, and CM recovery. After extensive testing, re-resting, and training,  Apollo 4 launched successfully on November 9, 1967 at 07:00:01 a.m. EST from Launch Complex 39-A at  Cape Canaveral FL. There were no delays in the preflight preparations and with the weather cooperating, there were no delays during countdown. During the third orbit and after SPS engine burn, the spacecraft coasted to a simulated translunar trajectory, reaching an altitude of 18,079 kilometers. The launch marked the initial flight testing of the S-IC and S-II stages. The first stage, S-IC, performed accurately with the center F-1 engine cutting off at 135.5 seconds and the outboard engines cutting off at LOX (liquid oxygen) depletion at 150.8 seconds when the vehicle was traveling at 9660 km/h at an altitude of 61.6 km. Stage separation occurred only 1.2 seconds off the predicted time. Cutoff of the S-II occurred at 519.8 seconds. It was a triumphant, if subdued return to space flight, and moved NASAs goals to reach the Moon farther forward. The spacecraft performance went well, and on the ground, people heaved a huge sigh of relief.   A Pacific Ocean landing occurred on November 9, 1967, 03:37 p.m. EST, just eight hours and thirty-seven minutes and fifty-nine seconds after takeoff. The Apollo 4 Spacecraft 017 splashed down, missing its planned impact point by only 16 kilometers. The Apollo 4 mission was a success, all  objectives were achieved. With the success of this first all up test, the Apollo program resumed manned missions and moving toward the eventual 1969 target for the first human landing on the Moon during the  Apollo 11 mission.  After the loss of the Apollo 1 crew, the Apollo 4 mission benefitted from many tough (and tragic) lessons learned.
