Project Overview

• This project concerns the renovation of an
  existing steel warehouse into a useable teen
  center. The building is located at 585 Broadway
  in Bangor next to the Salvation Army store. The
  teen center development project rose from a need
  for a new facility.

Project Overview

• Geotechnical
• Drainage problems around the building
• Transportation
• Unpaved area in front of building
• Non-signalized intersection problem area for
  traffic
• Structural
• Is building safe to use?
• No bathroom utilities

5
Geotechnical Aspect

• Received aerial photographic data
• Ground Survey around the building and parking lot
  and generated contours
• Received soil classifications of area

Transportation Aspect

• Conducted traffic study of the non-signalized
  intersection
• Traffic count and traffic delays
• Located existing parking lot lines using global
  positioning satellites
• Design of parking lot completed

Structural Aspect

• Have measured all structural members
• Finished structural analysis of frame, taking
  into consideration snow, wind and dead loads
• Snow and wind loads figured from ASCE Standard
  7-05 Minimum Design Loads for Buildings and Other
  Structures and the 2000 International Building
  Code
• Designed bathroom slab

Structural Analysis

• We analyzed the structure using two
• different methods
• Beam-Column Analysis (CIE 443)
• Matrix Analysis (CIE 440)

Bathroom Design

• Slab is 10 feet wide and 60 feet long
• Concrete 3000 psi
• Slab Thickness 5.5 inches

• Live Loads Considered
• Public Rooms 100 psf

• Dead Loads Considered
• Concrete 150 pcf
• Partitions 4 psf
• Misc. Dead Loads 15 psf

32
Bathroom Design

• Reinforcement
• 4 rebar for main reinforcement
• 3 rebar for temperature and shrinkage

• Spacing of Reinforcement
• 4s spaced at 11.5 inches
• 3s spaced at 16 inches

• Bond and Development Length
• A design assumption made was that the bathroom
  slab will be tied into the existing foundations
  of the warehouse and the Salvation Army store

33
Bathroom Design
Holes will be drilled into existing foundations
and rebar inserted 14 inches on each side
1.0 (lt12 inches of fresh concrete below rebar)
1.0 (uncoated rebar)
0.8 (lt7 rebar used)
1.0 (normal weigh concrete used)
