BSCI 4610 Test 1 - Holley

Hoisting and access are considered top considerations in site utilities.

T

Sites with sand while easy to move, pose security issues

T

Temp. underpinning insulations are considered real schedules activities with real potential to impact the schedule.

T

A dewatering systems with multiple pvc pipes are installed in a sleeve around a project perimeter os called

well point

In a vertical build proj. which componet is the ultimate goal to release the next set of activities

building pad

Ultilty trenching can impact surroudning activities

T

Wether or not shallow foundations can be formed is primarily dependent on soil type

T

Since sewerlines under a footprint are gravitiy driven they would typically be installed before foundations

FALSE / sewer lines have leniance

dispacement cast piles

many in number, small in diameter

Post. tension would require less steel tonnage but the PM would need to think about time allowed to cure so tendons may be stressed.

T

In most multi story CIP frames, the SOG would be placed after the foudations but before the first set of verticals

F

permanent power availability can have a significant impact on a previous schedule based on being able to drive equipment motors at design speed, and also to provide actual permanant lighting quailty for finishies installation.

T

power circuit homeruns are time consuimg as they are always required to be run overhead

False

all of the following are electrical distrubution componets that require rough in activites, except:

- MC cable,

-EMT,

-Rigid conduit,

- bus duc

ALL

2 MEP trades left up to the contractor to design and coordinate

electrical and fire protection

MEP trades would have very few activities in finishes

F

In a typical vertical building project. most mep systems rough-in is overhead

T

MATCH

Ductwork ----> static pressure impact

DWV ------> maximum gravity pitch

Homreruns and circuits .... maximum bent and pull points

choose prior to interior stud framing

Overhead MEP

typically "heating water" activities represent shorter lengths of piping but with larger heavier comps. than chilled water

FALSE

most hVAC hyrdronic piping systems are in the form of an

close loop system

delivery of mep equipment such as VAV rarely has and impact on the schedule

False

typically mep activities would follow distribution activities as soon as they are completed

F (inspections)

which of the following is a drawback to "high pressure spiral" ductwork from a scheduling perspective

lenghthy, double walled, large

typically gyp board would require overhead and in wall rough in to be complete

False

fire protection would normally be installed as a dry pipe system

False

for cassions being installed at depths of 25 to 35 ft typically one drill rig team might expert to intall 1 to 2 per day

true

primarily connections in steel frames are in

shear

the staging and handling of steel is deliberate, because the double handling of member is inefficient and expensive

TRUE

misc. activities (moment plates etc.) in the erection of the steel are typically installed very quickly and at a fraction of the time as the steel frame tonnage

false

Procurment activities are considered real activities event hough they occur off site

True

in a steel frame building the slab on grade would always be poured before the frame is erected

FALSE

CIP part that most influences the schedule

cold joints

in multi story projects, small improvments to the duration of the CIP frame is typically have significant impact on schedule

TRUE

re-sharing typically impairs a CIP project schedule because its spacing can impact at what point framing and rough in activities can begin.

TRUE (its required duration to stay there can impact the next lift)

What releases the most work based on tributary area?

columns

vertical cold joints in slab spans are often a necessary ; these joints ould typically be formed as close as possible to vertical members

False

lag associated with wreck and reshore activities should be applied with considerations of non working days because slab occurs without repect to the work week

TRUE

all of the following are benefits of splitting large elevated slabs into multiple pours expect

minimize the use of pumps

3 things a schedule needs

Activities, Durations, Logic

Most MEP activities are

Finish to Start

Which is faster Foamglass insulation or Fiberglass insulation?

Fiberglass
