All


Answers:

The maximum duration by which an activity can be delayed

without affecting its immediate successor.

The maximum duration by which an activity can be delayed

without affecting the finish date of the project.

An activity type in which each resource assigned to the

activity works according to its own resource calendar.This is

most commonly used when several people are involved in an

activity but they work separately.

P3 schedules a meeting activity at a time when all the

resources assigned to it can work on it at once for entire

duration of activity. This is used when group of people must

work on an activity simultaneously.

A restriction we impose on an activity that sets its early andlate start dates equal to the specified date without affecting

the logic. So we select mandatory constraint.



All


Answers:

Resource leveling reduces the resource conflicts and

minimizes the effect of resource overloads or demands and

makes use of positive float available by delaying some

activities. Select leveling then select resources to be leveled

and run to execute. In forward leveling some activities shift toa later date.

Minimum limit = minimum resources which we can arrange at

a time. Similarly maximum limit is the maximum number of

resources one can arrange from all sites. If we don¶t assign

limits it means that whatever the resource units a graph

displays we can arrange them by hook or crook.

Budget is dividing into 2 headings. Internal which is also

called as budget cost breakdown. Secondly, external budget

or billing which is for payment certificate or monthly progress

billing. In internal budget, the total cost is broken down into

equipment, labor, overheads, direct labor, in-direct labor +

expected profit. It is favorable for monitoring cash and

performance trends by comparing with the actual which are

traced from site.

Where as external or billing diagram is prepared for billing

purpose by multiplying the progress percentage in activity

budget.



All


Answers:

Click tools ± tabular reports ± cost ± loading

Add a report, select resources as cash or all resources click

format ± organize by cash select monthly ± execute cost

loading report and prepare a monthly billing distribution.

An activity type which spans a group of activities for

summarizing purposes. It is done by selecting activity type as

hammock and linking the activity with predecessor as first

activity and successor as last activity with SS and FF

relationships.

By actualizing actual start or actual finish.

First click tools, options, summarization and select cost.

Then view ± activity form ± cost then actual cost to date or

this period.

By interacting with finance manager thereby creating costcode dictionary

in P3. Click data ± cost accounts and then enter all cost

codes.



All


Answers:

Then view form, cost, select cost account where resource is

related to.

EG. Execution works

Resources are excavator, operator, soil or earth work.

Associate cost account 10101 and category EQPT

±E, for excavator similarly

operator ±L as manpower and soil ±M as material. And so

on.

To eliminate the loop, click tools, schedule, Schedule now

and execute the report. It will show where wrong relationship

is causing a loop.

EX. Activity 102 linked to 103 and 103 linked to 104 and 104

linked to again 102 forming a loop. Eliminate the wrong

relationship leading to 102 from 104. And run the schedule by

F9.

Filter the activities in p3 by selecting activities whose percent

comp. NE zero. Then execute it. Copy by highlighting the

filtered activities and paste it on .XL sheet then format it as

convenient for presentation.



All


Answers:

Click ± tools, project utilities, export, add, give a name

Then name the file at the place of P3

Type as dbase III file then save

It will appear in Excel then save as in EX format by specifying

a name.

If we enter bill of quantities in our activity budget by allocating

resources it gives rise to billing diagram.

Similarly if we enter internal budget excluding profit it gives

rise to our estimated budget.

We load bill of quantities (BOQ) with cost for billing purpose.

And internal budget for internal cost monitoring.

If heavy billing is occurring at a latter stage of the project or

activities which have large amount associated with its

resources occur in the last stages of project is treated as

back-loaded schedule.Similarly if heavy billing is occurring in the initial stages of the

project schedule thereby allocating maximum resources is

regarded as front loaded schedule.



All


Answers:

A bell shape curve or s-curve which will show smooth

distribution of resources across time.

Percent complete is the proportion of the resource

requirement of the activity that has been completed. If unspecified P3 calculates budgeted cost for work performed

x with schedule percent complete.

Whereas percent expended is a calculated value based on

actual cost to date and original budget cost. Or it is the

proportion of the cost budget that has been spent. Or it

differs from percent complete which represents the amount of

work accomplished rather than the proportion of the

resources expended.

Revision of budget is done at a time when there is a change

order initiated by client involving extra work for the existing

activity. It can be entered as a separate activity grouping with

change order activities apart of tender activity or by revisingthe budget quantity and cost in the original activity.



All


Answers:

Earned value is also called budgeted cost for work performed

(BCWP).

It is also called ACWP. Or the cost actually incurred for the

work accomplished up to data date. The cost of the work is

independent of the value of work, or the planned cost.

Earned value ± minus BCW should be (+)ve

Earned value ± ACWP should be (+)ve if we are gaining

profit.

By executing graphical report and comparison with the target.

Firstly prepare a cost loading report from P3. Export it to XL.This distribution is based on budget. Actual shall be traced

from site and updated to P3 to execute the report.

Click tools, tabular reports, cost ± control ± then execute

detail roll up of cost report. Or tools, tabular reports, cost ±

earned value report.

We go through the drawings, specifications, contract, bill of

quantities, scope of works. Coordination with tendering

manager, direct or project manager is carried out.



All


Answers:

Execute resource loading report in tabular form or format ±

organize ± organize by resource and enter the activities as

1. Material submittal

2. Material approval.

3. Placement of P.O.

4. Material fabrication .5. Material delivery.

6. Material QA/QC before installation.

These activities are to be sequentially linked to installation

activity. Then organize by material to give rise to procurement

schedule for monitoring.

By past experience or by stipulated period of contract or by

negotiation with managers.

We begin cladding tilling from top floor coming down to

ground floor for better alignment and workability.

By stretching a single activity bar spanning total length

of project and allocating all the indirect manpower and

expenses to it.



All


Answers:

Secondly by converting the last 1/3 span with reduced

overheads or indirect manpower namely all office stuff

QA/QC, managers, engineers, finance dept, HR dept.

Create custom data items as WEGT. % and earned value

EVWT. And select precision in a schedule which is costloaded. Then go to tools global change and add the following

items:

ThenWEGT. EG budget cost- BC/total cost of the project

EVWT = earned value or progress = EVWT EQ WEGT X

PCT

EVWT EQ EVWT / 100In both the operations run global change to execute the

conversion of cash into weighted PCT.

Separate the direct and indirect cost by assigning different

category as direct labor, indirect labor.
