OVERVIEW :
THE CIVIC CENTER TRANSFER FACILITY IS ONE OF THE POINTS OF INTERFACE BETWEEN EXPRESS BUSES AND THE SHUTTLE VEHICLE SYSTEM AT EITHER END OF THE 16TH STREET TRANS ITWAY/MALL PROJECT IN DOWNTOWN DENVER, COLORADO.
THE TRANS ITWAY/MALL IS A MAJOR TRANSPORTATION PROJECT IN THE CENTRAL BUSINESS DISTRICT OF METROPOLITAN DENVER. THE PROJECT WILL TRANSFORM 16TH STREET BETWEEN BROADWAY AND MARKET INTO A TREE-LINED PEDESTRIAN PRECINCT. ELECTRIC SHUTTLE CARS THE ONLY VEHICLES ALLOWED ON THE MALL WILL CARRY PASSENGERS TO AND FROM TRANSPORTATION TRANSFER FACILITIES LOCATED AT EACH END. EXPRESS COMMUTER BUSES WILL ENTER THE TRANSFER FACILITY WHERE RIDERS WILL TRANSFER TO TRANSITWAY VEHICLES. SHUTTLES WILL LEAVE THE TERMINALS EVERY 70 SECONDS STOPPING AT EACH BLOCK ALONG 16TH STREET.
THE FOLLOWING PAGES SUMMARIZE THE DESIGN CRITERIA AND THE PROGRAM INFORMATION FOR SCHEMATIC DESIGN OF THE CIVIC CENTER TRANSFER FACILITY AIR RIGHTS. THIS DOCUMENT REPRESENTS A COMPOSITE OF INFORMATION ASSEMBLED TO DATE ON THE DEVELOPER'S REQUIREMENTS, DESIGN ASSUMPTIONS, AND POLICY DECISIONS AFFECTING DESIGN OF THE CIVIC CENTER TRANSFER FACILITY. THE DESIGN IS BASED UPON CRITERIA MUTUALLY UNDERSTOOD AND ACCEPTED BY THE TRANS ITWAY/MALL ARCHITECT I.M. PEI & PARTNERS, DEVELOPER JOHN H. GALBREATH, INC., THE REGIONAL TRANSPORTATION DISTRICT, PUBLIC AGENCIES, AND OTHER INVOLVED PARTIES.


PROBLEM STATEMENT :
PROGRAM :
THE SUCCESS OF THE TRANSITWAY/MALL DEPENDS HEAVILY ON THE EFFICIENCY AND ENVIRONMENT OF THE TRANSFER FACILITIES AT EITHER END. THE CIVIC CENTER TRANSFER FACILITY MARKS THE SOUTHEASTERN END OF THE TRANSITWAY AND OCCUPIES THE BLOCK BOUNDED BY BROADWAY, LINCOLN, COLFAX AND 16TH AVENUE. THE DEVELOPMENT WILL CONTAIN A BUS CONCOURSE, A TRANSITWAY VEHICLE INTERCHANGE, A 450,000 SQUARE FOOT OFFICE FACILITY, AND A 350 ROOM HOTEL.
#TO DEVELOP THIS BLOCK INTO A VITAL ASSET TO THE LIFE OF DENVERS CBD AND THE TRANSITWAY/MALL.
TO MAKE THIS DEVELOPMENT A FUNCTIONAL AND EFFICIENT EXPRESSION OF CIRCULATION, BOTH FROM THE ASPECTS OF A TERMINAL AND AN INTERNAL MACHINE IN WHICH PEOPLE INHABIT.
TO DESIGN A PHYSICAL RESPONSE TO THE NEW DEVELOPMENT OCCURRING AROUND THE SITE AND TO THE FORMAL STRUCTURES OF THE CIVIC CENTER AREA.
THE FOLLOWING AIR RIGHTS OVER THE TRANSIT CENTER ARE BASED ON THE PROPOSAL BY A PRIVATE DEVELOPER AFTER CONDUCTING THE NECESSARY FINANCIAL FEASIBILITY ANALYSIS TO INSURE SOUNDNESS OF THE PROJECT.

NET RENTABLE SQUARE FOOTAGE.................450,000 SQ.FT.
THIS IS BASED ON AN 85$ EFFICIENCY OF RENTABLE AREA TO CORE AREA

ANALYSIS


DEFINITION
THE CIVIC CENTER TRANSFER FAC ILITIY IS TO BE CONSTRUCTED IN THE BLOCK BOUNDED BY BROADWAY, COLFAX AVENUE, LINCOLN STREET AND 16TH AVENUE. THE REGIONAL TRANSPORTATION DISTRICT OWNS THE NORTH HALF OF THE BLOCK IN FEE AND HAS A 99-YEAR LEASE ON THE SOUTH HALF OF THE BLOCK. THIS 133,000 SQUARE FOOT PARCEL IS IDEALLY SUITED FOR MIXED-USE DEVELOPMENT. IT IS SITUATED ON THE FRINGE OF OFFICE, RETAIL, AND GOVERNMENTAL RELATED ACTIVITIES. THE STATE CAPITOL AND CIVIC CENTER PARK ARE LOCATED TO THE SOUTH OF THE SITE WITH ITS STRONG ATTRACTION FOR TOURIST AND GOVERNMENTAL EMPLOYEES. THE OTHER THREE SIDES ARE JOINED BY SOME OF DENVER'S NEWEST OFFICE AND RETAIL FACILITIES, GREAT-WEST PLAZA, COLORADO STATE BANK AND COLUMBIA CENTER, WITH THE ADDITION OF THE 16TH STREET MALL TO THE NORTHWEST, THIS MAKES THIS SITE A VERY VITAL ELEMENT IN DENVER'S CBD.

PEDESTRIAN
CIRCULATION
WITH THIS DEVELOPMENT FUNCTIONING AS A TRANSPORTATION TERMINAL, MUCH LESS A LINK BETWEEN THE CIVIC CENTER AREA AND THE 16TH STREET MALL, THERE IS A DIAGONAL DIRECTION OF PEDESTRIAN MOVEMENT WHICH WOULD ALIGN WITH THE MALL IF THE DESIGN ALLOWED. YOU ALSO HAVE A STRONG PEDESTRIAN MOVEMENT ALONG BROADWAY AND COLFAX DUE TO BUS SERVICE. THIS ALLOCATION OF SPACE FOR PEDESTRIAN MOVEMENT ALONG THE SITE AND WITHIN THE CONFINES IS AN IMPORTANT ELEMENT OF THE TERMINAL DESIGN. SUCH SPACE MUST NOT ONLY BE ADEQUATE FROM A CAPACITY STANDPOINT, BUT MUST ALSO BE COHERENT AND ATTRACTIVE.

VEHICULAR
CIRCULATION
THE MAIN CONCEPT OF THE 16TH STREET MALL IS TO LESSEN TRAFFIC CONGESTION IN THE DOWNTOWN AREA BUT, IRONICALLY, THIS SITE IS BOUND ON THREE SIDES BY THREE OF THE MOST HEAVILY TRAVELED ARTERIES. LINCOLN STREET DEFINES THE EAST BOUNDARY WITH TRAFFIC FLOWING NORTH AND BROADWAY DEFINES THE WEST WITH TRAFFIC FLOWING SOUTH. BOTH THESE ARTERIES CROSS COLFAX AVENUE WITH ITS EAST-WEST TRAFFIC CREATING TRAFFIC CONGESTION AT TWO CORNERS OF THE SITE. THIS ALSO INHIBITS PEDESTRIAN MOVEMENT FROM THE CIVIC CENTER AREA ONTO THE SITE.
ANOTHER CONFLICT AROUND THE SITE IS THE CONTINUATION OF THE 16TH STREET PEDESTRIAN MALL ONTO THE SITE UPON CROSSING BROADWAY AT THE NORTHWEST CORNER. THIS CREATES A PROBLEM FOR BOTH THE PEDESTRIAN AND THE SHUTTLE VEHICLE.
THESE CONFLICTS, PLUS THE ONE-WAY DIRECTIONAL FLOWS OF THESE ARTERIES, WILL BE A STRONG DESIGN DETERMINANT IN OFF-STREET VEHICLE ACCESS TO PARKING, SERVICE, AND DROP-OFF FOR THE HOTEL.

MASS TRANSIT
THE SUCCESS OF THE TRANS ITWAY/MALL DEPENDS HEAVILY ON THE EFFICI-ENCY AND ENVIRONMENT OF THE TRANSFER FACILITY.
IN ORDER TO GET PEOPLE TO USE AND SUPPORT MASS TRANSIT, IT MUST BE DESIRABLE FOR THEM. BY THIS, I MEAN EASY, EFFICIENT, AND DEPENDABLE.
A SHUTTLE VEHICLE WILL ARRIVE ON THE SITE FROM THE 16TH STREET MALL ON THE BROADWAY LEVEL INTO A PUBLIC SPACE.
UPON DEPARTURE, THEY SHOULD HAVE THE OPTION TO DESCEND TO THE CONCOURSE LEVEL TO THE EXPRESS BUS TERMINAL OR ENJOY THE'AMENITIES OF THE PLAZA. ALL THIS SHOULD BE CLEAR TO THE PASSENGER UPON ARRIVAL AND OCCUR QUITE QUICKLY UPON DEPARTURE. SOME FORM OF PROTECTION FROM THE ELEMENTS SHOULD BE INCORPORATED INTO THE DESIGN AND THE CONTROL OF ALL ACTIVITIES SHOULD RESPOND TO THIS FUNCTION OF THE PLAZA.
THE EXPRESS BUSES WILL BE ALLOWED ACCESS TO THE CONCOURSE LEVEL VIA 16TH AVENUE SINCE THIS IS LESS CONGESTED AND EASIER TO CONTROL. DEPARTURE WILL OCCUR ALSO ON 16TH AVENUE FOR THOSE BUSES TRAVELING NORTH OR EAST AND ON BROADWAY FOR THOSE TRAVELING SOUTH OR WEST. THIS PREVENTS ANY EXPRESS BUSES FROM CROSSING THE TRAFFIC OF THE 16TH STREET PEDESTRIAN MALL.

SERVICE
VEHICLES
SERVICE VEHICLES WILL BE HANDLED IN MUCH THE SAME MANNER AS EXPRESS BUSES. ALL SERVICE VEHICLES WILL ENTER THE SITE FROM 16TH AVENUE AND DELIVERIES WILL BE MADE TO THE BROADWAY LEVEL.
THE OFFICE TOWER AND HOTEL WILL HAVE SEPARATE SERVICE AREAS WHICH WILL BE SHAPED BY THE RETAIL FACILITIES WITHIN THAT AREA. SOME ON-STREET DELIVERIES WILL BE ALLOWED AT DESIGNATED AREAS DURING OFF-PEAK HOURS ONLY AND AT NIGHT.


VIEWS Sl AMENITIES
THIS SITE HAS SEVERAL AMENITIES THAT DO NOT OCCUR IN MOST URBAN DEVELOPMENTS. VIEWS OF SOME TYPE OCCUR ON ALMOST ALL SIDES OF THE DEVELOPMENT AND WITH THE EXTRA ATTRACTION OF THE 16TH STREET MALL IT MAKES FOR A VERY EXCITING EXPERIENCE IF CAPITALIZED ON. THE ROCKY MOUNTAINS CAN BE SEEN TO THE SOUTHWEST, TO THE WEST ON THE LOWER LEVELS OF DEVELOPMENT AND AS FAR AS THE NORTHWEST ON THE UPPER LEVEL. THERE IS ALSO THE ADDITIONAL VIEW DOWN THE 16TH STREET MALL AND THE CAPITOL FROM THE INTERIOR OF THE SITE. ALONG THE SOUTH ARE THE VIEWS OF THE CIVIC CENTER AREA AND ITS ADJOINING STRUCTURES. ALL OF THIS MAKES FOR A VrRY EXCITING EXPERIENCE IF THESE VIEWS ARE PRESENTED IN THE APPROPRIATE WAYS.

VIEW EASEMENT
THE VIEW EASEMENT IS A REQUIREMENT SET DOWN BY RTD AND ITS ARCHITECTURAL ADVISOR, I.M. PEI & PARTNERS. IT HAS NEVER BEEN OFFICIALLY DOCUMENTED OR DEFINED, BUT IS LEFT TO THE DEVELOPER'S DISCRETION ON HOW IT SHOULD BE INTERPRETED. THE BASIC REQUIREMENT IS THAT THE VIEW OF THE CAPITOL ALWAYS BE MAINTAINED FROM THE 16TH STREET MALL. THE ELEVATION OF THE CAPITOL IS SUCH THAT DEVELOPMENT CAN CONTINUE ACROSS THE SITE, BUT' ONLY ONE LEVEL ABOVE THE LINCOLN LEVEL AND THIS PRESENTS SOME PROBLEM. THEREFORE, THIS RESTRICTION DIVIDES THE SITE INTO TWO PARTS WITH THE SLICE TAKEN IN LINE WITH THE 16TH STREET MALL.
