- THE BATTLE OVER PRESIDENT - BIDEN'S COVID VACCINE MANDATES - IS HEATING UP, AS HIS - ADMINISTRATION DEFENDS THE NEW - RULES IN THE FACE OF LEGAL - CHALLENGES. - YESTERDAY, A FEDERAL APPEALS - COURT IN LOUISIANA TEMPORARILY - HALTED THE VACCINE MANDATE FOR - EMPLOYEES OF LARGE COMPANIES. - IT REQUIRES NEARLY 100 MILLION - PRIVATE SECTOR EMPLOYEES TO GET - VACCINATED BY JANUARY 4, OR BE - TESTED WEEKLY. - THE RULE APPLIES TO COMPANIES - WITH 100 WORKERS OR MORE. - MORE THAN TWO DOZEN STATES, - INCLUDING MISSOURI, ARIZONA AND - NEBRASKA, HAVE ALREADY FILED - LAWSUITS AGAINST THE RULE, - ARGUING THAT THE MANDATE IS - UNCONSTITUTIONAL. - U.S. SURGEON GENERAL DR. VIVEK - MURTHY DEFENDED THE BIDEN - ADMINISTRATION'S MANDATE TODAY. - >> THE PRESIDENT AND THE - ADMINISTRATION WOULDN'T HAVE PUT - THESE REQUIREMENTS IN PLACE IF - THEY DIDN'T THINK THAT THEY WERE - APPROPRIATE AND NECESSARY, AND - THE ADMINISTRATION IS CERTAINLY - PREPARED TO DEFEND THEM. - >> Sreenivasan: WHEN ASKED - WHETHER THE ADMINISTRATION PLANS - TO EXTEND THE MANDATE TO SMALLER - COMPANIES WITH FEWER THAN 100 - EMPLOYEES, MURTHY SAID, “NOTHING - IS OFF THE TABLE.” - LATER THIS MONTH THE BIDEN - ADMINISTRATION WILL FACE THE - FIRST TEST IN ITS PUSH TO GET

- WORKERS VACCINATED WITHIN ITS - OWN GOVERNMENT. - ABOUT FOUR MILLION FEDERAL - WORKERS, FROM F.B.I. AGENTS TO - U.S. FOOD AND DRUG - ADMINISTRATION WORKERS, ARE - REQUIRED TO BE VACCINATED BY - NOVEMBER 22. - AN INVESTIGATION CONTINUED TODAY - INTO FRIDAY'S TRAGEDY AT A - HOUSTON CONCERT THAT KILLED - EIGHT PEOPLE RANGING IN AGE FROM - 14-27. - POLICE SAY THEY ARE REVIEWING - EYEWITNESS VIDS THAT CONTINUE - TO SURFACE. - THE DEATHS AND INJURIES ARE - BEING ATTRIBUTED TO “CROWD - SURGE” AS RAPPER TRAVIS SCOTT - BEGAN HIS PERFORMANCE FRIDAY - NIGHT. - THE AREA WHERE THE ASTROWORLD - CONCERT TOOK PLACE REPORTEDLY - HAD ROOM FOR 200,000 PEOPLE, BUT - OFFICIALS LIMITED ADMISSION TO - 50,000. - LATE YESTEAY, HOUSTON CHIEF OF - POLICE TROY FINNER SAID THE - INVESTIGATION WILL INCLUDE - REPORTS OF NARCOTIC OVERDOSES. - >> THIS IS NOW A CRIMINAL - INVESTIGATION THAT'S GOING TO - INVOLVE OUR HOMICIDE DIVISION AS - WELL ANARCOTICS, AND WE'RE - GOING TO GET DOWN TO THE BOTTOM - OF IT. - >> Sreenivasan: IN INSTAGRAM - POST SCOTT ISSUED A TEARFUL - STATEMENT SAYING HE WAS - ABSOLUTELY DEVASTATED.

- >> Sreenivasan: FOR MORE ON WHAT - HAPPENED AND THE ONGOING - INVESTIGATION, I SPOKE WITH - "HOUSTON CHRONICLE" MUSIC CRITIC - AND REPORTER JOEY GUERRA WHO WAS - AT THE ASTROWORLD CONCERT ON - FRIDAY. - JOEY, YOU'VE BEEN WRITING AND - REPORTING ABOUT THIS ALL - WEEKEND. - I THINK WE ARE A LITTLE NOW - AWARE OF WHAT HAPPENED, BUT I - THINK THE QUESTION EVERYONE HAS - IS HOW DID THIS HAPPEN? - YOU WERE THERE. - >> I THINK THAT'S THE BIG - QUESTION. - I MEAN, THERE ARE SO MANY - QUESTIONS I THINK SURROUNDING - THIS. - THERE HAVE BEEN, YOU KNOW, THERE - HAVE BEEN RUMORS THAT THERE WERE - DRUGS INVOLVED. - YOU KNOW, OBVIOUSLY, I THINK THE - INITIAL SPECULATION WAS THAT - PEOPLE WERE JUST TRAMPLED - BECAUSE THERE WAS SO MUCH OF A - CROWD. - BUT IT'S JUST I THINK THERE ARE - SO MANY QUESTIONS STILL. - OBVIOUSLY, I THINK THERE WERE - SOME ISSUES WITH CROWDING AND - PEOPLE PUSHING AND CROWD SURGES - AND THINGS LIKE THAT, BUT I - THINK THERE MIGHT BE MORE TO - THIS THAN JUST THAT. - >> Sreenivasan: GIVE US A SENSE - OF WHAT THIS SPACE IS LIKE WHERE - ALL THESE PEOPLE WERE. - >> WELL, THE SPACE WHERE THIS IS - AT IS KIND OF ADJACENT TO THE

- BIG STADIUM HERE IN TOWN, SO - IT'S A HUGE KIND OF AREA WITH - PARKING LOTS AND GRASS. - THEY HAD TO STAGE A SET UP THAT - WERE VERY WELL SPACED. - THERE WAS LOTS OF SPACE IN - BETWEEN. - CARNIVAL, MIDWAY GAMES, THINGS - LIKE THAT. - THE AREA IN FRONT OF THIS STAGE - HAS A LOT OF GRASS, A LOT OF - CONCRETE. - I KNOW PEOPLE HEAR THESE NUMBERS - AND THINK, HOW DID THEY NOT KNOW - THIS WAS GOING TO HAPPEN? - BUT I THINK ANYBODY WHO'S BEEN - TO A FESTIVAL KNOWS, YOU KNOW, - THEY KIND OF KNOW THE AREA. - THEY PREPARE FOR SOMETHING LIKE - THIS. - I MEAN, YES, THERE WERE A LOT OF - PEOPLE IN THE FRONT WHERE TRAVIS - WAS PERFORMING, BUT IF YOU WERE - OUT OF THAT IMMEDIATE AREA, - THERE WAS LOTS OF PEOPLE WALKING - AROUND. - PEOPLE WERE IN LINE GETTING - FOOD. - I MEAN, THERE WAS LOTS OF ACTION - STILL HAPPENING RIGHT BEHIND. - I MEAN, IT WASN'T LIKE EVERY - SINGLE PERSON THERE WAS PACKED - IN, SO. - >> Sreenivasan: TELL US A LITTLE - BIT ABOUT WHAT IS THE AVERAGE - TRAVIS SCOTT CONCERT LIKE FOR - SOMEONE WHO HASN'T ATTENDED? - I MEAN, IN YOUR REPORTING, YOU - DESCRIBE A KIND OF ENERGY THERE. - TELL ME ABOUT THAT. - >> YEAH, I MEAN, I THINK THAT'S - REALLY IMPORTANT TO UNDERSTAND

- IS THAT IF YOU'VE NEVER BEEN TO - A TRAVIS SCOTT SHOW, I MEAN, THE - ENERGY KIND OF EXCHANGE BETWEEN - HIM AND E CROWD IS IT'S LIKE - NOTHING I'VE EVER SEEN. - I MEAN, I THINK THE CLOSEST - COMPARISON IS MAYBE LIKE A BOY - BAND CONCERT WHEN YOU HAVE - PEOPLE CRYING AND KIND OF - UNCONTROLLABLE, THAT'S KIND OF - THE ENERGY HERE. - I MEAN, HE CALLS HIS FANS RAGERS - AND, YOU KNOW, THERE ARE MOSH - PITS. - AND IT'S INTERESTING BECAU I - THINK THE AVERAGE TRAVIS SCOTT - FAN IS PROBABLY A MALE FROM 16- - 21 YEARS OLD, WHICH WE SAW AT - THIS CONCERT. - I MEAN, IT'S LOTS OF MALES, SO - THERE'S LOTS OF KIND OF PENT-UP - ENERGY AND, YOU KNOW, IT CAN - KIND OF SPILL INTO AGGRESSION AT - SOME POINT. - >> Sreenivasan: YOU'VE BEEN - WATCHING CLOSELY A LOT OF THE - VIDEOS THAT HAVE COME OUT OF THE - EVENT ITSELF. - WHAT WERE YOU ABLE TO LEARN FROM - SOME OF THE VIDEOS THAT FANS - WERE SHARING AROUND THE MOMENTS - THAT IT WAS HAPPENING? - >> I THINK FOR ME, HONESTLY AND - PROBABLY A LOT OF PEOPLE THAT - WEREN'T IN THAT MIX, IT WAS JUST - REALLY SHOCKING TO SEE WHAT WAS - HAPPENING. - I MEAN, I WAS, YOU KNOW, OUTSIDE

- ON THE GROUND, BUT I WAS FURTHER - BACK. - SO, ME AND EVERYONE AROUND ME - HAD NO CLUE WHAT WAS GOING ON. - WE SAW, OF COURSE, WE SAW - EMERGENCY VEHICLES COMING IN AND - THINGS LIKE THAT. - WE KNEW HE STOPPED THE SHOW, BUT - IT FELT LIKE, KIND OF, NORMAL - FESTIVAL HAPPENINGS, YOU KNOW. - THINGS HAPPEN AND PEOPLE GET, - YOU KNOW, PEOPLE GET SICK OR - NEED HELP. - SO, IT WASN'T UNTIL AFTER WHEN - YOU'RE LEAVING AND YOU'RE - CHECKING SOCIAL MEDIA, YOU SEE - THESE VIDEOS OF PEOPLE - PERFORMING C.P.R., BEING CARTED - AWAY UNCONSCIOUS, YOU KNOW, - PEOPLE, LIKE, JUST CLAMORING TO - GET OUT. - IT WAS JUST HONESTLY, REALLY - SHOCKING IF YOU WEREN'T IN THERE - TO REALLY UNDERSTAND THAT ALL - THIS WAS GOING ON. - >> Sreenivasan: JOEY GUERRA OF - THE "HOUSTON CHRONICLE." - THANKS SO MUCH. - >> THANK YOU. - >> Sreenivasan: IN IRAQ TODAY, - PRIME MINISTER MUSTAFA AL- - KADHIMI SURVIVED A PRE-DAWN - ASSASSINATION ATTEMPT AT HIS - RESIDENCE. - FOOTAGE SHOWED THE EXTENT OF THE

- OPPOSITION GROUPS HAD JOINED - THEIR CAUSE TO OUST THE PRIME - MINISTER. - NICARAGUANS WENT TO THE POLLS - TODAY TO CAST THEIR BALLOTS IN - AN ELECTION THAT THE U.S. AND - OTHER CRITICS ARE DISMISSING AS - A SHAM. - CURRENT LONGTIME PRESIDENT - DANIEL ORTEGA IS ALL BUT CERTAIN - TO WIN A FOURTH TERM. - SINCE MAY, ORTEGA'S POLICE HAVE - DETAINED NEARLY 40 OPPOSITION - LEADERS, INCLUDING SEVEN - PRESIDENTIAL CANDITES. - THE GOVERNMENT ALSO BANNED LARGE - CAMPAIGN EVENTS AND CLOSED MANY - VOTING STATIONS. - ORTEGA FIRST CAME TO POWER IN - 1979, WAS VOTED OUT IN THE 1990s - AND RETURNED TO POWER IN 2007. - FOR MORE NATIONAL AND - INTERNATIONAL NEWS, VISIT - pbs.org/newshour. - >> Sreenivasan: THE LATEST TREND - IN THE WORLD OF CONSTRUCTION IS - SOMETHING YOU MIGHT NOT EXPECT. - ARCHITECTS ARE DESIGNING TALL - BUILDINGS USING MASSIVE TIMBER - BEAMS THAT PROPONENTS SAY ARE - MUCH MORE ENVIRONMENTALLY - FRIENDLY THAN STEEL AND - CONCRETE. - NEWSHOUR WEEKEND SPECIAL - CORRESPONDENT MEGAN THOMPSON - RECENTLY TRAVELED TO MILWAUKEE, - WISCONSIN, TO SEE A 25-STORY - BUILDING THAT WILL BE THE

- TALLEST MASS TIMBER PROJECT IN - THE U.S. WHEN IT'S COMPLETED. - THIS STORY IS PART OF OUR - ONGOING SERIES "PERIL & PROMISE: - THE CHALLENGE OF CLIMATE - CHANGE." - >> Reporter: IN DOWNTOWN - MILWAUKEE, WISCONSIN, A NEW - LUXURY APARTMENT BUILDING IS - RISING IN THE UPSCALE EAST TOWN - NEIGHBORHOOD. - THE PROJECT IS CALLED "ASCE," - AND TO MOST PASSING BY, IT - PROBABLY LOOKS LIKE A TYPICAL - HIGH-RISE CONSTRUCTION SITE. - TURNS OUT, IT'S ANYTHING BUT. - >> TO SAY IT'S VERY UNUSUAL IS A - MASSIVE UNDERSTATEMENT. - >> Reporter: TALL BUILDINGS LIKE - THIS ARE USUALLY BUILT OUT OF - STEEL AND CONCRETE. - BUT THIS ONE? - IT'S BEING BUILT MOSTLY OUT OF - WOOD. - HOW UNIQUE IS THIS PROJECT HERE - IN THE UNITED STATES? - >> OH, IT'S-- IT'S - UNPRECEDENTED. - FROM AN APPROVALS STANDPOINT, - FROM A FIRE TESTING STANDPOINT, - FROM A DESIGN AND ENGINEERING - STANDPOINT, THERE WAS SO MUCH - INNOVATION IN THIS PROJECT. - >> Reporter: TIM GOKHMAN IS THE - MANAGING DIRECTOR OF NEW LAND - ENTERPRISES, THE DEVELOPMENT - COMPANY BEHIND ASCENT. - BUILDING IT OUT OF TIMBER WAS - HIS IDEA.

- CONSTRUCTING WITH WOOD ISN'T - NEW-- WE'VE BEEN DOING IT FOR - EONS-- BUT THIS USES A NEW - TECHNOLOGY CALLED "MASSIVE - TIMBER" OR MASS TIMBER FOR - SHORT. - MASS TIMBER, WHICH IS - SURPRISINGLY FIRE RESISTANT, HAS - MADE IT POSSIBLE TO CONSTRUCT - WOOD BUILDINGS THAT ARE LARGER - AND TALLER THAN EVER BEFORE. - IN FACT, WHEN THE 25-FLOOR - ASCENT BUILDING IS COMPLETED - NEXT SUMMER, IT WILL BE THE - TALLEST STRUCTURE OF ITS KIND IN - THE WORLD. - WHAT MADE YOU SAY, "I WANT TO - BUILD A HIGH RISE OUT OF - TIMBER?" - >> ONCE YOU GO INTO A BUILDING - THAT HAS EXPOSED WOOD, YOU - UNDERSTAND RIG AWAY. - IT'S BEAUTIFUL AND YOU FEEL - GREAT IN IT. - IT IFAST, IT IS PRECISE, IT IS - LIGHT, IT IS CAN. - >> Reporter: THE FIRST SIX - FLOORS, WHICH WILL HOUSE A - PARKING GARAGE AND POOL, ARE - BUILT FROM STEEL AND CONCRETE. - SO ARE THE ELEVATOR SHAFT, - STAIRWELL AND FOUNDATION. - BUT THE 19 UPPER FLOORS ARE - CONSTRUCTED FROM GIGANTIC MASS - TIMBER BEAMS, COLUMNS AND - BOARDS. - >> THIS IS RELATIVELY NEW, - ESPECIALLY IN THE UNITED STATES. - IT'S MORE COMMON IN SOME PARTS - OF EUROPE, ESPECIALLY - SCANDINAVIA.

- >> Reporter: DAVID CORR IS A - CIVIL ENGINEER AND DIRECTOR OF - ARCHITECTURAL ENGINEERING AND - DESIGN STUDIES AT NORTHWESTERN - UNIVERSITY. - HE'S CURRENTLY STUDYING THE - STRUCTURAL PROPERTIES OF MASS - TIMBER. - SO, WHEN WE'RE TALKING ABOUT - MASS TIMBER OR TALL TIMBER, - WHAT'S NEW HERE? - >> THIS WOULD BE A TWO BY FOUR, - THIS IS A SORT OF FAMILIAR PIECE - OF TIMBER. - IF YOU TEAR DOWN THE WALLS OF - YOUR HOUSE, YOU WOULD FIND SMALL - PIECES OF WOOD LIKE THAT BEHIND - THE WALLS, AND THAT'S WHAT - CARRIES ALL THE LOAD IN YOUR - HOUSE. - SO, THIS IS AN EXAMPLE OF MASS - TIMBER. - IT'S IMPORTANT FOR PEOPLE TO - UNDERSTAND THAT THIS IS A VERY - SMALL PART OF SOMETHING THAT - WOULD BE VERY LARGE. - SO, THERE'D BE A SINGLE LAYER ON - THE BOTTOM AND THEN A LAYER OF - GLUE AND THEN ANOTHER LAYER, - LAYER OF GLUE. - IT'S KIND OF LIKE MAKING A CAKE - OUT OF WOOD, WHERE THE GLUE IS - THE FROSTING. - >> Reporter: THIS MATERIAL IS - CALLED "CROSS LAMINATED TIMBER," - BECAUSE EACH LAYER IS GLUED - CROSSWISE, WHICH MAKES THE - MATERIAL STRONGER. - SO, IT'S KIND OF LIKE PLYWOOD ON - STEROIDS. - >> THAT'S EXACTLY RIGHT. - IT'S STRUCTURAL SCALE PLYWOOD, - PLYWOOD ON STEROIDS. - >> Reporter: THESE HUGE SLABS - CAN CARRY MASSIVE LOADS, BUT, - INCH FOR INCH, TIMBES NOT - QUITE AS STRONG AS STEEL AND - CONCRETE, CORR SAYS. - SO, IT'S NOT GREAT FOR WIDE, - OPEN FLOOR PLANS WITH NO

- SUPPORTING COLUMNS. - AND THERE WON'T BE A WOOD - SKYSCRAPER AS TALL AS THE EMPIRE - STATE BUILDING ANY TIME SOON. - MASS TIMBER WAS FIRST PIONEERED - IN AUSTRIA IN THE '90s, AND IS - GAINING POPULARITY IN THE UNITED - STATES. - IN 2013, THE U.S. HAD 26 MASS - TIMBER BUILDINGS. - TODAY THERE ARE 576 BUILT OR - UNDER CONSTRUCTION, AND SEVERAL - HUNDRED MORE ARE IN THE WORKS. - >> THERE'S A LOT OF APPEALING - ATTRIBUTES TO MASS TIMBER. - ONE OF THEM IS THE - SUSTAINABILITY ASPECT. - SO, ONE OF THE DOWNSIDES OF - CONCRETE AND STEEL IS THEY HAVE - A LOT OF WHAT'S KNOWN AS - EMBODIED CARBON. - >> Reporter: MEANING, PRODUCTION - OF STEEL AND CEMENT IS VERY - POLLUTING, CONTRIBUTING - SOMEWHE AROUND 15% OF GLOBAL - CARBON DIOXIDE EMISSIONS. - ON THE OTHER HAND, TREES ARE - WHAT'S KNOWN AS A "CARBON SINK." - THEY SUCK IN CARBON AND LOCK IT - IN. - AND STUDIES HAVE SHOWN, - REPLACING STEEL AND CONCRETE - WITH TIMBER CAN LOWER A - BUILDING'S GLOBAL WARMING - POTENTIAL. - BUT CUTTING DOWN TOO MANY TREES - CAN CONTRIBUTE TO GLOBAL - WARMING, AND SOME ENVIRONMENTAL - GROUPS ARE WARY OF AN INCREASED

- DEMAND FOR WOOD. - >> THERE'S STILL A LOT OF - QUESTIONS, AND THE JURY IS STILL - OUT ON WHETHER OR NOT IT CAN BE - ACHIEVED SUSTAINABLY. - >> Reporter: KIRIN KENNEDY - DIRECTS PEOPLE AND NATURE POLICY - FOR THE SIERRA CLUB. - SHE WORRIES THAT A LOGGING BOOM - COULD LEAD TO THE LOSS OF A - CRITICAL TOOL FOR FIGHTI - CLIMATE CHANGE, BECAUSE ONCE - THEY'RE CUT DOWN, TREES STOP - ACTIVELY SUCKING IN CARBON, AND - LOSE A PORTION OF THE CARBON - THEY STORED. - >> THE QUESTION THAT WE AND - OTHER FOLKS ARE WONDERING IS, IS - THERE ENOUGH FORESTED AREA TO - BOTH BE ABLE TO SUSTAIN MASS - BUILDING AND PROTECT OUR - FORESTS, OR ARE OUR FORESTS - BETTER LEFT INTACT AS A NATURAL - CARBON SINK? - >> Reporter: SHE ALSO NOTES, OUR - FORESTS ARE IMPORTANT WILDLIFE - HABITATS AND NATURAL BUFFERS - AGAINST FLOODING AND EROSION. - SO, KENNEDY AND SOME OTHER - ENVIRONMENTALISTS ARE HESITANT - TO EMBRACE MASS TIMBER JUST YET. - >> THIS IS EUROPEAN WHITE - SPRUCE. - SO, THIS IS SUSTAINABLY FARMED. - >> Reporter: JASON KORB IS THE - ARCHITECT OF THE ASCENT

- BUILDING. - HE SAYS THE TEAM WAS CAREFUL TO - SOURCE THEIR WOOD FROM - SUSTAINABLY MANAGED FORESTS. - HAD YOU EVER DESIGNED A TIMBER - BUILDING BEFORE? - >> NEVER ONCE. - WE WENT BIG. - >> Reporter: WHAT WAS THAT - PROCESS LIKE? - >> I THINK WE KNEW ABOUT 5% OF - WHAT WE NEEDED TO KNOW WHEN WE - STARTED IN MARCH OF 2018. - AND I LIKEN IT TO GOING TO - GRADUATE SCHOOL FOR TWO YEARS. - >> Reporter: PART OF WHAT KORB - HAD TO FIGURE OUT WAS HOW TO GET - THE CITY OF MILWAUKEE TO APPROVE - HIS PLANS. - THE TALLEST MASS TIMBER - BUILDINGS RIGHT NOW ARE IN - EUROPE, INCLUDING THE VERY - TALLEST, AN 18-STORY TOWER IN - NORWAY. - BUT THE TALLEST BUILDINGS IN THE - U.S. ARE BETWEEN 7-10 STORIES, - IN PART BECAUSE AMERICAN - BUILDING CODES HE BEEN SLOW TO - CATCH UP. - ARCHITECT JASON KORB SPENT MORE - THAN TWO YEARS PROVING HIS - 25-STORY BUILDING WOULD BE SAFE, - INCLUDING ANSWERING THE QUESTION - OFTEN ON PEOPLE'S MINDS: HOW - WILL THE STRUCTURE HOLD UP IN A - FIRE? - THE ASCENT TEAM WORKED WITH THE - U.S. FOREST SERVICE TO DO - EXTENSIVE FIRE TESTING, THE - FIRST OF TIR KIND EVER - CONDUCTED. - NINE WOOD COLUMNS WERE BURNED IN - A FURNACE FOR THREE HOURS

- STRAIGHT, AT TEMPERATURES - REACHING MORE THAN 2,000 - DEGREES. - >> MASS TIMBER DOESN'T BURN. - IT'S VERY DIFFERENT FROM YOUR - STANDARD TWO BY FOUR. - IT CHARS. - >> Reporter: THAT CHARRING LAYER - ACTUALLY ACTS AS INSULATION, - PROTECTING THE REST OF THE WOOD. - THE ASCENT COLUMNS CHARRED, AND - HELD UP. - THE COLUMNS WERE DESIGNED A FEW - INCHES WIDER TO ALLOW FOR THIS - FIRE-PROOFING LAYER. - IT WAS JUST ONE OF THE MANY NEW - THINGS ARCHITECT JASON KORB HAD - TO DO. - >> THE AMOUNT OF - PRE-CONSTRUCTION WORK THAT NEEDS - TO BE DONE IN A TALL TIMBER - BUILDING IS PRETTY MUCH LIKE - NOTHING WE'VE EVER SEEN, - ESPECIALLY IN A RESIDENTIAL - BUILDING. - >> Reporter: THAT'S BECAUSE, IN - TRADITIONAL CONSTRUCTION, ALL - THE HOLES FOR THINGS LIKE - PLUMBING, WIRING AND DUCTWORK - ARE DRILLED IN THE STEEL OR - FORMED IN THE CONCRETE AS THE - BUILDING IS GOING UP. - BUT IN TIMBER, ALL OF THAT IS - CUT BEFOREHAND, SO KORB AND HIS - TEAM HAD TO CREATE A PRECISE - DIGITAL MODEL. - >> THE BUILDING WAS MODELED DOWN - TO THE LAST SCREW. - THOSE FILES ARE THEN FED TO THE - MANUFACTURER, AND THEY ARE LASER - DRILLED TO A TOLERANCE OF ABOUT - THREE MILLIMETERS. - >> Reporter: KORB SAYS AT THE

- TIME IT COST LESS TO IMPORT THE - WOOD FROM AUSTRIA THAN IF HE - BOUGHT FROM A NORTH AMERICAN - SUPPLIER, SO THE 3,700 PRECISELY - CUT PIECES WERE SHIPPED TO - MILWAUKEE, WHERE THE - CONSTRUCTION TEAM IS NOW - PUTTING THEM ALL TOGETHER. - >> AND WE'RE CURRENTLY - INSTALLING THE COLUMNS FROM - LEVEL 19-20. - >> Reporter: CHRIS JOHANSEN IS - THE PROJECT MANAGER FOR C.D. - SMITH, THE CONSTRUCTION COMPANY - BUILDING ASCENT. - >> HEADS UP, HEADS UP! - >> Reporter: EACH ENORMOUS - COLUMN IS HOISTED BY A CRANE. - SPECIAL GLUE IS PUMPED INTO THE - HOLE. - THEN THE COLUMN IS CAREFULLY PUT - INTO PLACE. - >> THERE'S NOT ONE COLUMN, - THERE'S NOT ONE BEAM, ONE FLOOR - PANEL THAT IS INTEHANGEABLE. - SO, WE HAVE DETAILED PLANS, A - LOT OF COLOR CODING AND A LOT OF - COMMUNICATION TO ENSURE THAT - WE'RE INSTALLING THINGS IN THE - RIGHT PLACE. - >> Reporter: ALL THE WOOD IS - TREATED WITH A WATERPROOF - COATING, AND THE BUILDING'S - GLASS FACADE WILL PROTECT THE - TIMBER STRUCTURE INSIDE, WHERE - ABOUT 50% OF THE WOOD WILL - REMAIN EXPOSED. - ANY WOOD OUTSIDE IS PROTECTED BY - SHEETING, A WATER-RESISTANT - SEALANT AND INSULATION.

- ASSEMBLING THE STRUCTURE IS - COMPARATIVELY QUICK, AT LEAST - FOUR MONTHS FASTER THAN IF THIS - WAS ALL STEEL AND CONCRETE. - AND CHRIS JOHANSEN NEEDS LESS - LABOR FOR THIS PART-- ABOUT A - QUARTER OF THE WORKERS. - HE SAYS THE WORK IS ALSO MUCH - LESS STRENUOUS AND DIRTY. - >> ONE OF THE GUYS TOLD ME THAT, - HIS WIFE IS QUESTIONING IF HE'S - GOING TO WORK BECAUSE HE'S NOT - COMING HOME COVERED IN CONCRETE. - >> Reporter: FEWER WORKERS AND A - FASTER JOB MEAN BIG SAVINGS ON - CONSTRUCTION COSTS, BUT THE WOOD - ITSELF ISN'T CHEAP. - ARCHITECT JASON KORB ESTIMATES - IT'S ABOUT 10% MORE THAN WHAT - YOU'D PAY FOR CONCRETE IN - MILWKEE. - BUT THAT PRICE MIGHT START - COMING DOWN AS THE SUPPLY IN THE - U.S. GROWS. - THE CANADA-BASED COMPANY - STRUCTURLAM OPENED ITS FIRST - U.S. PLANT THIS SUMMER IN - ARKANSAS, A FEW HOURS FROM - WALMART'S HEADQUARTERS. - THAT'S BECAUSE WALMART IS - BUILDING ITS NEW CORPORATE - CAMPUS OUT OF-- YOU GUESSED IT-- - MASS TIMBER. - 2.4 MILLION SQUARE FEET OF - OFFICE SPACE. - >> IT'S NOT JUST MY HOPE, BUT MY - PREDICTION IS THAT IT'S A MATTER - OF TIME UNTIL THE UNITED STATES

- OVERTAKES THE REST OF THE WORLD - IN PRODUCTION AND ASSEMBLY AND - IN THE USE OF BUILDINGS LIKE - THIS. - >> Reporter: FROM THE AVALANCHE - OF INTEREST TIM GOKHMAN SAYS - HE'S GOTTEN IN ASCENT, HE COULD - BE RIGHT. - HE'S ALREADY RENTED NEARLY 10% - OF THE UNITS. - NORMALLY HE WOULDN'T HAVE EVEN - STARTED LEASING YET. - ASCENT IS SLATED TO OPEN NEXT - JULY. - >> Sreenivasan: IN 2009, ARTIST - JASPER WONG FOUNDED AN - INTERNATIONAL MURAL ARTS - FESTIVAL AND ARTS OUTREACH - PROGRAM IN HONG KONG. - SINCE THEN, THE FESTIVAL HAS - TAKEN PLACE IN CITIES WORLDWIDE, - WITH THE GOAL OF BUILDING - COMMUNITY BY BEAUTIFYING - PHYSICAL SPACES. - NEWSHOUR WEEKEND SPECIAL - CORRESPONDENT KARLA MURTHY - TRAVELED TO CLEVELAND, OHIO, - THIS SUMMER TO SEE HOW THE CITY - CELEBRATED THIS LARGER THAN LIFE - ART FORM. - >> Reporter: ON THE CORNER OF - SUPERIOR AND EAST 39th STREET IN

- CLEVELAND, OHIO, A ONCE-BLANK - WALL IS BEING TRANSFORMED INTO - ART. - >> THIS IS PROBABLY THE BIGGEST - PIECE I'VE EVER DONE. - IT'S A LITTLE BIT INTIMIDATING - AT FIRST, BUT, YEAH, I JUST LOOK - AT IT AS ANOTHER BIG CANVAS. - >> Reporter: LOCAL ARTIST - ANTWOINE WASHINGTON IS PAINTING - HIS FIRST LARGE SCALE MURAL, - WITH THE HELP OF ANOTHER ARTIST, - CHAD FEDOROVICH. - >> I USUALLY DRAW AND PAINT - REALISTICALLY, BUT WITH THIS - STYLE I WANTED THIS TO BE A - LITTLE BIT MORE COLORFUL, TO - HAVE SOME FUN, - >> Reporter: WASHINGTON'S - PREVIOUS WORK HAS BEEN SHOWN IN - GALLERIES AND MUSEUMS INUDING - THE CLEVELAND MUSEUM OF ART. - >> A LOT OF PEOPLE IN MY CULTURE - DON'T GET A CHANCE TO GO TO THE - MUSEUMS, OR EVEN FEEL - COMFORTABLE TO GO TO MUSEUMS OR - SOMETIMEA BUILDING DOESN'T - FEEL WELCOMING TO THEM. - AND SO, TO BE ABLE TO PUT WORK - INSIDE OF THE COMMUNITY WHERE - THEY'RE ABLE TO WALK PAST IT - EVERY DAY, ABLE TO INTERACT WITH - IT EVERY DAY, I LOVE IT. - >> Reporter: WASHINGTON IS ONE - OF OVER 20 ARTISTS WHO - PARTICIPATED IN AN INTERNATIONAL - MURAL FESTIVAL BROUGHT TO THE - CITY THIS PAST SUMMER CALLED“ - CLEVELAND WALLS!”

- DURING THE FESTIVAL, 20 MURALS - WERE PAINTED ON BUILDINGS ACROSS - THE MIDTOWN NEIGHBORHOOD. - >> AS SOMEONE WHO IS FROM HERE - AND GREW UP IN THE NEIGHBORHOOD, - BEING ABLE TO SEE COLOR IN AREAS - IN WHICH YOU DON'T TYPICALLY SEE - IT, BEING ABLE TO EXPERIENCE ART - IN A WAY THAT'S TANGIBLE, - SOMETHING THAT YOU CAN WALK UP - AND INTERACT WITH, IS DEFINITELY - INVIGORATING. - >> Reporter: SAMIRA MALONE WORKS - FOR A NONPROFIT CALLED MIDTOWN - CLEVELAND THAT'S HOSTING THE - FESTIVAL. - THE NEIGHBORHOOD NEAR DOWNTOWN - IS HOME TO 2,000 RESIDENTS AND - ALSO ATTRACTS OVER 18,000 PEOPLE - DAY WHO WORK IN THE AREA. - >> OUR NEIGHBORHOOD HAS A VERY - INTERESTING FABRIC. - WE HAVE A STRONG INDUSTRIAL - FOOTPRINT, WE ALSO HAVE SEVERAL - MAJOR COMMERCIAL CORRIDORS, - BUT WE DO HAVE A RESIDENTIAL - POPULATION. - WE HAVE A LARGE BLACK POPULATION - AS WELL AS A LARGE, LARGE ASIAN - POPULATION, SO THE ARTISTS THAT - WE SELECTED ARE WORKING WITH - THROUGH THIS PROCESS ARE ALSO - REFLECTIVE OF BOTH OF THOSE - COMMUNITIES. - >> Reporter: CAN YOU TELL ME A - LITTLE BIT ABOUT WHAT IT IS - YOU'RE PAINTING? - >> IT'S A MANDARIN CHARACTER. - IT MEANS STRONG.

- THE REST CAN BE OPEN TO - INTERPRETATION. - >> Reporter: JULIA KUO IS A - TAIWANESE-AMERICAN ILLUSTRATOR - FOR CHILDREN'S BOOKS AS WELL AS - NEWSPAPERS AND MAGAZINES. - SHE SAYS MOST OF HER WORK IS A - SOLITARY PROCESS. - PAINTING A MURAL IN PUBLIC HAS - ALLOWED HER TO INTERACT WITH - PEOPLE. - >> YOU KNOW, SOME PEOPLE ARE - DOING, LIKE, THE MURAL TOUR, BUT - OTHER PEOPLE JUST LIVE HERE AND - THEY PASS THROUGH AND THE LIKE, - WELL, THEY'RE GOING TO HAVE TO - LOOK AT THIS EVERY DAY. - I'M GOING TO LEAVE, RIGHT? - SO, TO HEAR PEOPLE'S COMMENTS - IS, LIKE, REALLY NICE, TOO. - IT'S JUST DIFFERENT FOR ME. - >> Reporter: AND WHAT DO YOU - HOPE PEOPLE WILL GET OUT OF - WALKING BY? - >> I THINK I HOPE THEY'LL JUST - ENJOY THE IMAGES. - I ENJOY DRAWING PEOPLE WHO LOOK - LIKE ME, AND, KIND OF, THE WAY I - SEE MYSELF IN THE WORLD. - SO, IT'S NICE TO PUT OUT A - LITTLE BIT OF THE REPRESENTATION - THAT I ALWAYS WISH THAT I WOULD - VE MYSELF. - >> Reporter: THAT'S ALSO THE - GOAL OF ANTWOINE WASHINGTON'S - WORK. - >> THE CONTENT AROUND BLACK - FAMILY IS OFTEN OVERLOOKED. - AND SO, I WANTED TO ACTUALLY PUT - THAT BLACK FATHER BACK INTO THAT

- Hey, Jeff, where do you go, - and what do you do when - you're on vacation? - - Okay, Aiello's, let's roll. - - [Narrator] My answer this - time was to take a camera - on vacation and shoot a travel - show in Aspen, Colorado. - But as you're about to see, - this family adventure - did not start out smooth. - - We're at the gate and - we saw it starting to snow - outside here in Denver. - And I thought this - probably isn't good for us. - - [Narrator] But - the lessons learned - in this travel nightmare - were worth the pain. - There is a beautiful - trout stream running - through the middle - of this valley. - Because when travel - throws a curve ball. - And at some point - it always will. - Butt slide, nice. - Learning to pivot quick - and make a new plan - will deliver you - to places and moments like this. - - We got a double, - we got a double. - Both Conly and Mark are - hooked up on fish right now. - - That you'll remember - long past things - like a white knuckle - blizzard death drive. - I quite possibly had the - best pancake of my life. - I'm going to go ahead
