A crest vertical curve begins with a 1.2% upgrade and ends with a 1.08% downgrade. The PVC is at station 125+00 with an elevation of 711.10ft and the PVT is at station 131+30. The distance to the highest point is.............ft from the PVC.

A Seven-sided closed field traverse has the following angles and distances in meters which were measured using a Total station:

AB = 51.7660;

BC = 76.9470;

CD = 37.0700;

DE = 29.2019;

EF = 28.7758;

FG = 36.7056;

GA = 41.9555;

The adjusted angles are as follows:

A = 128˚27’02”;

B = 101˚41’49”;

C = 102˚22’05”;

D = 143˚12’43”;

E = 161˚08’23”;

F = 131˚57’22”;

G = 131˚10’35”;

DE = 29.2019;

EF = 28.7758;

FG = 36.7056;

GA = 41.9555;

azimuth AB =251˚00’00''

question

1. Compute the coordinates of the traverse stations using coordinates of station A as 1,000.000 N, 1,000.000 E.
2. Compute the area enclosed by the traverse using the co-ordinate method.
3. It was decided to divide the traverse into two parts AGFED and DCBA, find the area of each part and the length and direction of AD.

“My Lord A Valuation Is Not The Valuation'The Above Sentence Was Made By An Astute Valuer Who Was Defending His Values In A Court. The Judge And All The Learned In The Courtroom Were Baffled And Astonished. After 30min Of Elucidating On The Statement, The Entire Court Cannot But Applauded The Valuer.The judge concluded ‘’you Valuers are really friend whose are learned’’.

As a friend of the Valuer and a Land Surveyor in the making,Critically examine the statement,with examples and illustrations convince a client why a valuation is not the valuation.

What will you propose for a concrete mix design to be used in constructing a bridge pier during a cold winter month. The bridge is designed to be constructed on a site where sulfate attack on the concrete is a problem. In this project, high cost is not allowed and the concrete’s cost must be priority without lowering quality.

I have a BIM model for a pavement structure with all the relevant data. The question is how do I use this to predict dynamic, thermal effects, creep, complex load patterns, and large displacements using a combination of Navisworks and COMSOL?. Try to explain the important steps....like where should I start and end?

A proposed highway has two tangents of bearings N 45°54 ^,36^,, E and N 1°22 ^,30^,, W. The highway design engineer, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 43.00 ft. The PI is at station 65+ 43.21 Determine:

(a) The central angle of the curve

(b) The radius of the curve

(c) The length of the tangent of the curve

(d) The station of the PC

(e) The length of the curve

(f) The station of the PT

(g) The deflection angle and chord from the PC to the first full station on the curve
